The Year in Review The close of 2019 finds us not only at the end of another year, but also rounding out a decade. How can it be 2020 already?!?

Looking back through my phone’s photo files, it seems like just yesterday that I was sorting seeds for our winter Seed Exchanges and here I sit again, surrounded by boxes of seed packs that need labeling and counting.

This year, I was lucky to travel with fellow garden communicators. I spent a week each in Denver, CO, and Salt Lake City, UT, and return from each city with renewed gratitude for our green East Coast climate.

It was not a great year for my own garden nor our community garden plot.

The very wet spring delayed plantings and much of the direct-sown seeds washed away. Then the late summer Your editor attending a “Purple Rain” drought put a fast end to the season. movie party in Columbia, MD. Still, there were a few successes.

My garlic bulbs were huge and flavorful, my marigolds won ribbons at the county fair, and lilac shrubs yielded armfuls of bouquets. I was able to grow enough cut flowers and herbs to share with attendees at a talk I gave at a local DC library.

Speaking of talks, I spoke at more than two dozen garden clubs and at a number of other locations this past year—from independent garden centers to local public gardens. At the Rooting DC conference back in February, I gave three talks in one day—each on a different topic and to a standing-room-only crowd. That was an exhausting day that I will make a note not to repeat.

I also had the privilege of attending talks by dozens of other garden speakers and learning from them. I pick up not only horticultural knowledge, but also tips on becoming a better public speaker. I won’t soon forget the talk I attended this fall by Christopher Woods, author of Gardenlust, that started with him running down the aisle to a rock anthem, then making everyone get up to dance along with him, Now that is a way to get the room energized!

Outside the garden world, I attended my fair share of concerts, art exhibits, and movie screenings. If you didn’t know it already, I am not a morning person, due in large part to my late nights out.

Looking back through my scheduler, I see days crammed with deadlines and conference calls, as well as numerous meetings with project partners and press tours for story ideas. These last few weeks of the year, I plan to figure out how we will celebrate the upcoming 15th anniversary of this publication. Yes, time sure does fly!

I look forward to a busy 2020.

Happy gardening,

Meet Ruthie Mundell

By Taylor Markey

Community Forklift Uplifts with Upcycling Washington Gardener Magazine recently had a chance to speak with Ruthie Mundell, donations outreach & special projects coordinator, Community Forklift board member, Build Reuse, on what Community Forklift does, what led her there, and what projects they have coming up.

Tell us a little bit about Community Forklift and its mission.

Community Forklift (communityforklift. org) is called that because we aim to lift up communities through reuse. The idea is that something like 40 percent of our nation’s solid waste is made out of building materials. If you think about it, every time that a house gets demolished or every time somebody renovates a kitchen and takes out some old cabinets, it’s all going to landfill incinerators, which cause greenhouse gases and are usually located in poor communities.

We’re trying to be one solution. The idea is that if somebody has a kitchen or renovation project in their house, 6

WASHINGTON GARDENER DECEMBER 2019

or even their entire house, that they want to get rid of, and it’s still in decent shape, then, instead of throwing it in a dumpster, they donate it to us, and we’ll come pick it up for free. They get a nice tax deduction and all of that good material that’s reusable can come to us.

We can sell it cheaply, so folks can afford repairs. We’re located in a working-class part of the DC region, so basically instead of wealthy communities sending their construction waste to working-class communities for them to deal with the pollution, we’re sending it as resources to them because we haven’t trashed everything up and wrecked it all; we carefully removed it, basically turning waste into resources.

Our mission is to make repairs affordable, create green jobs for folks facing barriers to employment, and help prevent construction waste and reduce construction waste and demands for new materials.

Tell us about your background.

I have always known that I wanted to

be a treehugger. When I was young, I thought that meant I was going to be in environmental law or be a scientist.

I was not a great student at science. I went to a pre-law program and did okay, but it was not where my gifts lay.

I did not go straight to law school after college, I took a little time. I did fundraising for an environmental education organization for a while, and then, I was in my early twenties and my mother got sick, so I moved back home to Southern Maryland, where I grew up, and took care of her until she passed away.

After that, I wasn’t quite ready to go back to an office job, so I found an organic farm for a time, which was wonderful, but very hard work. I was making minimum wage as a farmhand, I was still looking for work.

I was at Green America’s Green Festival—a big show for green businesses. I came across this booth, and there was a guy who was explaining that they were about to open this place called Community Forklift near Edmonston, MD. He explained the concept—salvaged parts for old house parts and keeping stuff out of the landfill—and I thought, “That’s perfect for me.” I had renovated an old farmhouse with my parents when I was a teenager, so I loved old stuff, and knew a bit about remodeling, renovation, and old house parts, and the mission really just spoke to me. He said, “Well, we’re hiring for a CEO,” and I said, “I’m 24. I don’t think I’m quite CEO-level yet, but why don’t you hire me when you find your CEO?” There were just a few of us in the beginning and everybody did everything—ran the cash register, researched prices, picked up donations—but we just kept growing and growing. I sort of carved an image for myself here because I was so passionate about the mission that I was always the person who was going to community festivals saying, “Hey, check this place out.”

I would go on Craigslist, Facebook, and community discussion lists and say, “Have you heard of this place?”

I became the marketing & outreach director just because that was where my passion was. I wanted to spread the gospel. I carved out that spot for myself.

We kept growing and now we have 50 people.

NEIGHBORnwork What is a typical workday like for you?

It depends on the time of year. We’ll do a lot of community events here at the warehouse to bring people together and to teach people about repair and upcycling. In the nicer weather of the spring and the fall, I may be planning workshops or getting ready for events that we have coming up here. We just had the Green Friday event, where people can make presents instead of going to the mall to buy plastic junk. We’re Pallet alwaysfence tryingat to Wangari do creativeGardens things to get people thinking about ways they can reuse or upcycle stuff.

Some of my work is contacting people from the community who love us and who want to help us—kind of helping match them up with ways they can volunteer here, whether that’s teaching a workshop or a lawyer who just wants to get their hands dirty on the weekends, so they’ll help us process the donations.

What mistakes and triumphs have you Old roof �les garden encountered in = your work?edger We’ve been through a lot of debt in the early years, and we’re still climbing out of that. It was partly because there was a long learning curve with figuring out how to price things. We’d get amazing, really valuable antiques, and then we’d get very basic building materials—a toilet or a sink from five years ago from Home Depot—everything was just priced the same.

That was definitely hard at the beginning to figure out. It’s easy enough to look up something and say, “Oh, here is this piece of modern lumber. This is what is charged at Home Depot or Lowe’s.panel Okay,doors we’ll charge 40 percent Old wood —> Garden wall! less,” but it’s a lot harder with a vintage item to figure things out.

The problem was that we weren’t making enough money to cover our expenses. Yes, people donate the materials to us for free, but we put a lot of time and resources into this to pick up donations—gas and keeping our big trucks on the road.

In the early years, there were a few times I was never sure if I was going to get paid, but over time, the mission attracted so many interested, smart people, both volunteers and staff, that we kept getting more and more The Larkins builtyear, a treehouse efficient. Every there would with be

do, they would love this. We were right.

We had a lot of support from our community. Wonderful people came out to teach workshops and to exhibit, like the educational booth hosted by the Prince George’s County Master Gardeners.

Every year, it’s gotten bigger and bigger. Even that first year, we had people lined up outside the gate before we opened. It is like Black Friday for gardeners.

After that, we realized, “We hardly Jeff Wilkes built an insect hotel sell any gardening over the winter with scrapssupplies from the Forkli� anyhow, so let’s not even bother to put them out. Let’s just keep everything in storage, organize it all together, and then have it ready to go out the morning of the Garden Party every year.”

This year, I think we had something An arbor made of old secutity doors from like 75 people waiting in line before Community Forklift.

We also have so many more donations coming in. The word has been spreading. More and more folks are calling us up and saying, “Yeah, I have an entire house to donate. Will you come deconstruct it?” We’re working with partners who will deconstruct a house instead of demolishing it, basically taking it all apart by hand rather than bulldozing it.

Upside-down granite counter scraps make great pa�o stones

recently moved into a house in Laurel, MD, so I don’t have anything growing yet, but I am very proud of a place where I lived years ago in DC. It was a little rowhouse down off of H Street in Northeast, and the whole backyard was paved. It was ugly. It was backed by a garage that we couldn’t access. It was a rental property. There was a garage wall and completely paved, so it was hot.

I really wanted to at least grow tomatoes and have a little bit of a backyard sanctuary, so I took some panel doors and I painted the panel doors in bright colors and attached them along the fencing of the walls. I had very pretty, multi-colored garden walls and that did a lot to make the whole backyard look brighter. Then I did container gardening and I built some containers out of Forklift materials, and I got some really cool, over-sized flower pots here. They were wonderful and that’s what I grew my tomatoes in. I created myself a pretty little backyard sanctuary out of this ugly, paved mess. I was very proud of that.

Jeff Wilkes built an insect hotel Any final thoughts? with scraps from the Forkli�

I would like to say that Community Forklift would not be here without the support of the local gardening community, because the Garden Party that we’ve had every year has really helped us spread the word about our services.

That’s one of the best things for us.

The more thatCoopers we’ve been able to get the word The built a chicken coop out there, the more good stuff we’ve with materials from the Forkli� been able to keep out the landfill, and the more people we’ve been able to employ.

Garlic Shoots

Back in early November, I planted garlic. I see that some green leaves have already sprouted. Can I cut off these green shoots for a salad before winter kills the bulb?

No, don’t cut those leaves now! Your garlic won’t be killed by winter weather.

Protect it with shredded leaves or mulch, leaving about 1" of the green showing. In spring, pull back the covering when the soil warms and fertilize in mid-April and again in mid-May. Leaves will shoot up, and the bulb will bulk up.

Leaves begin to die back in late June/ early July. Harvest when ½ of the foliage turns brown. In our area, garlic is ready to be harvested around July 1.

Clivia Starting to Yellow

Many years ago, I purchased a Kaffir Lily (Clivia miniata) at the Philadelphia Flower Show and it has special meaning to me. Recently, the bottom leaves are turning yellow. What is causing this and what should I do? Also, sometimes it does not bloom well. Is it true that they need a rest period?

It is normal for the older leaves to turn yellow and eventually shrivel as the plant ages. Prune off the affected leaves. The rest of the leaves should be green, strappy, and healthy. Yellowing of younger leaves can indicate overwatering: a more-serious symptom. The potting mixture should dry out slightly between waterings when it is actively growing and completely dry out during the rest period.

Clivias do need a dormant period to help with blooming. Starting in late fall or early winter, withhold water and fertilizer and move the plant to a cooler area where temperatures are in the 40–50° F range. Keep it there for about 6–8 weeks, then move it back to a sunny location and begin to water again. You will soon see some new growth and a flower stalk. At this point, begin to fertilize it every two weeks with a water-soluble houseplant fertilizer at half-strength. They bloom best when pot bound. Repot your Clivia every three to five years in the spring, after the flowers fade, when necessary.

Ask the Expert

Evergreen for Screening

Unfortunately, I had to remove a spruce tree that blocked my house from the road. I need to replace it as soon as possible. Do you have any suggestions for an evergreen tree that will provide a screen and can I plant it now?

Evergreens are vulnerable to drying winds, freezing weather, and fluctuating winter temperatures. The damage shows up as browning of needles and tip dieback. If at all possible, wait until early spring to plant. There will be more choices of plant material in the spring as nurseries receive new shipments of trees for the planting season. Eastern red cedar (Juniperus virginiana), Norway spruce (Picea abies), Japanese cryptomeria (Cryptomeria japonica), and Green giant arborvitae (Thuja plicata ‘Green Giant’) are some suggestions for a replacement tree.

Nandina Invasive

My gardening friends and I have gotten into a discussion about nandinas. Is it true that they are now considered an invasive plant? We were also disturbed to hear that the berries are toxic to birds. Should nandinas be removed from landscapes?

As of May 14, 2017, the Maryland Department of Agriculture (MDA) added Nandina domestica to their Tier 2 invasive plants in Maryland. They are still sold, but appropriate signage has

to be posted in a conspicuous manner, informing consumers that the plant has the potential for environmental harm and to plant with caution.

Nandina was the subject of a February 2018 blog from the Maryland Invasive Species Council website titled “Not so Heavenly” (http://mdinvasives.org). According to the blog post, the plant has naturalized in two Maryland counties: Prince George’s and Frederick. Fortunately, there are attractive alternatives, such as itea (Itea virginica), fothergilla (Fothergilla gardenia or F. major), cranberry viburnum (Viburnum trilobum), and sweet shrub (Calycanthus floridus).

Then, there is the issue of berry toxicity and birds. The berries contain cyanide. There have been reputable reports about the death of cedar waxwings after feeding on nandina berries in Georgia.

We recommend replacing nandina, or at least removing the berries, and not replanting them. o Debra Ricigliano is a Certified Professional Horticulturist. She has worked as a horticulture consultant for the University of Maryland Extension Home and Garden Information Center since 1997.

Growing Amaryllis: Three-to-a-Pot

A single blooming amaryllis bulb can be a beautiful windowsill display in your home, but planting three to a pot is the key to creating a fuller potted plant display. Colorblends shared the best tips to successfully grow three-to-a-pot amaryllis. To get started, you will need: • Three top-size amaryllis bulbs • A broad, shallow pot with at least one drainage hole in the bottom (round pots work best); the minimum pot size should be 7 inches deep by 11 inches in diameter • Potting soil • A waterproof saucer or plate to catch the water under the pot • A cork or other pad to place underneath in case the saucer gets wet Once you have everything you need, it is time to begin planting. To plant your three-to-a-pot amaryllis, you should: Fill 1/3 of the pot with potting soil.

Place the three bulbs close together but not touching, approximately 1½ inches apart; Position each bulb so the bottom 2/3 will be buried, leaving the top 1/3 above the soil surface.

Add potting soil around and between the bulbs. Tamp the soil to seat the bulbs securely. Do not fill soil to the top of the pot; leave space below the rim for water to pool and drain when watered.

To ensure the best growth, you should water your bulbs well. During the 10

WASHINGTON GARDENER DECEMBER 2019

pre-growth stretch, water them sparingly. You can tell if water is needed by touching the soil and seeing if it is dry. After three to eight weeks, a stem will appear, and you should water as needed to keep the soil damp, but not wet or soggy.

Set the pot by a sunny window. The warmer the room, the faster the bulbs will grow. South- and west-facing windows offer the best light. You should turn the pot occasionally to encourage balanced growth, since amaryllis are phototropic and lean toward the dominant source of light. If they are in dim light, their stems may grow overly tall and become weak.

Once your flowers open, move the pot out of direct sunlight and keep them away from heaters or hot air vents, so the flowers will last longer. To keep the blooms looking fresh, snip off faded florets. If all of the florets on a stem are spent, cut off the stem about 2 inches above the bulb.

You can also cut stems from the pot for use as cut flowers, but do not cut them until their flower buds have opened. Never use scissors to cut them; always use a sharp knife, and make the cut about 2 inches above the bulb.

Refresh the water every three days or so and retrim the stem ends once or twice weekly, and they can last up to 10 days in the vase.

Leaving Crops Up Over Winter Can Improve Soil

Did you know that leaving plants in your garden over the winter can be good for the soil? According to the Soil Science Society of America (https://soilsmatter. wordpress.com), this is something that gardeners should consider on a yearly basis. Leaving the residue, also known as plant “litter,” over the winter provides numerous benefits for the soil and your garden.

By doing this, you can reduce erosion and the loss of valuable topsoil.

Residues cover soil and protect it during the non-growing season. It also helps soil to catch rainfall, which reduces the impact that rain can have on the soil surface. It will also slow down any flow of melting snow over the soil, which will

help protect the soil structure, keeping it intact for next year’s crops and gardens.

Leaving residue on the soil surface can also prevent soil crusting. Without the residue, the soil will not absorb any water, which can create little streams that can turn into larger streams. Such streams will carry away the soil and the important nutrients that it needs. By having residue, you can avoid this.

Not only is residue great for preventing soil crusting, it is also beneficial to reduce the growth of weeds. Weeds are often early spring germinators, but residue will limit the resources and space that the weed seedlings require to grow.

Residue also benefits the soil by providing it with shade, which regulates the soil temperature. It is important to keep the soil cool, because cooler soil temperatures provide more-suitable conditions for soil microbes, which are necessary for maintaining a productive soil for crop growth.

The cooler temperatures also aid in the retention of soil moisture, which is great for crop growth and seed germination in the spring.

Lastly, crop residue provides microhabits and a source of organic matter.

Micro-habits protect and benefit the germinating plant seeds and establishing seedlings, and organic matter provides an energy source for soil microbial populations, which results in faster decomposition rates and the release of essential nutrients for crop growth.

Organic matter also helps maintain good soil structure, which will reduce erosion, improve water infiltration, and soil aeration.

One caveat: Unhealthy plants—such as leaves with powdery mildew or other diseases—should be removed and discarded in the trash, not composted.

If you have not already cleared out your garden, you should try leaving residue in place to prepare for the upcoming winter months. o These tips were compiled by Jessica Kranz, a senior broadcast journalism major at the University of Maryland, College Park and an editorial intern at Washington Gardener this autumn.

Tomato Crokini F1 This small, round, cherry tomato crushed it as the winner of the AllAmerica Selections (AAS) trials for the best new edible plant tested in the Southeast region.

It was bred by H.M. Clause (http:// clausehomegarden.com), a company based in Portes-Les-Valence (in the French county of Drôme).

It has a very sweet (Brix of 8.5), light acidic taste, giving it the perfect sweet/ acid balance.

Pronounced like “rock” not “crook,” Crokini’s round fruits are small and firm with a crunchy texture and good flavor.

This winner gets high marks for durability because fruits do not crack on the vine, yielding up to 10–12 fruits per cluster. Crokini provides a lovely burst of sweetness.

Overall, the yield was better than comparisons because of the in-bred Late Blight resistance well into September. The Southern AAS judges like the better taste and texture as compared to Sweet Million.

It is also highly resistant to tomato mosaic virus, Fusarium wilt, root-knot nematodes, and tomato yellow leaf curl.

Overall, Crokini is a “cleaner” plant because it is slightly more compact than comparisons with evenly distributed fruit. o

PLANTprofile Pansies and violas are easy-care flowers that thrive in cool weather and add a bright spot to garden beds and container plantings.

These dainty blooms aren’t your grandmother’s old-fashioned flowers. Pansies and violas now come in dozens of colors, color combinations, bloom sizes, and growth habits (from mounding types to trailing). Recent introductions have improved their cold tolerance and blooming vigor as well.

There are more than 500 known species of violas and they are indigenous to every continent except Antarctica, according to Barbara Melera of Harvesting-History.com.

By the way, did you know the differences between a pansy and a viola? Although pansies are generally larger than violas, it is actually the petal count and position that differentiate them. Pansies have four petals pointing upward and only one pointing down. Violas have three petals pointing upward and two pointing down.

Pansies and violas (also known as Johnny Jump-ups) can be started from seed in the fall for spring blooms or in the spring for summer and fall blooms.

Pansies and violas are perennials that are hardy from Zone 3 to 9, although they are short-lived plants and usually treated as coolseason annuals.

They prefer highly composted, evenly moist soil and they bloom best in full to part-sun.

They go dormant in the heat of the summer and coldest parts of winter, but will begin to bloom again when the weather is more temperate in the spring and fall.

Give them a slow-release fertilizer mixed into the soil when planting them or added as a top dressing after planting. The best time to fertilize pansies and violas is in the early spring and again in late summer as they come out of their dormancy for fall blooming.

To keep them looking their best, deadhead them regularly (that is, removing the spent flowers and stems). When they become leggy and overgrown, you can cut back the whole plant to a couple of inches high to rejuvenate it.

In the winter, lightly mulch around the plants and keep them watered. If they are in a container, it is especially important not to let them dry out in the harsh winter winds.

Great companions to pansies and violas are snapdragons and sweet alyssum. o Kathy Jentz is the editor and founder of Washington Gardener Magazine.

BOOKreviews religious, medicinal, and celebratory rituals for many cultures throughout history.”

Coming into this book with no prior knowledge of floriography, I had great interest in finding out about how nature speaks to us and how we can speak through nature in return. “By creating a sentiment using the language of flowers, a posy can serve as a vehicle to convey profound messages that sometimes cannot be articulated in words.”

This book is great to flip through and very visually appealing. I would recommend it as a coffee table book, a gift to someone looking for wedding ideas, or some inspiration about bouquets for any occasion or emotion. o The Posy Book: Garden-Inspired Bouquets That Tell a Story

By Teresa H. Sabankaya with Foreword

by Amy Stewart Publisher: The Countryman Press List Price: $24.95 Order Link: https://amzn.to/2M0Yhtg Reviewer: Taylor Markey Teresa Sabankaya provides information about the language of flowers, posy recipes to help figure out what you want to say, and steps for how to make a posy in The Posy Book, which is complemented with beautiful photos taken by Danyelle Dee and illustrations

by Maryjo Koch. The book is also augmented with a modern floral dictionary.

For those who do not know (like me), posies are small flower bouquets, “like floral greeting cards,” as the author describes in her first chapter.

The Posy Book is split up into five main chapters: A Posy Primer, A History of the Language of Flowers, Posy Recipes, Making Posies, and The New Language of Flowers Dictionary.

These sections are followed up with a resource listing and an index of posy ingredients.

Although she explains that she is not a historical scholar, Sabankaya shows her interest and dedication to gaining knowledge on flowers and how they speak to us. In the introduction, she says that her purpose for writing this book is to inspire and “to impart the simple knowledge that flowers have captivated us for centuries, and they have played some role in symbolic 14

The Gardener Says: Quotes, Quips, and Words of Wisdom

By Nina Pick Publisher: Princeton Architectural Press List Price: $15.95 Order Link: https://amzn.to/2LXDRkN Reviewer: Jessica Kranz In Nina Pick’s The Gardener Says: Quotes, Quips, and Words of Wisdom, you will be exposed to an abundant number of quotes that showcase all of gardening’s many moods and phases.

The quotes in the book come from a range of different types of people, such as gardeners, poets, philosophers, and landscape designers, who highlight the

joys and challenges of gardening. Some of the quotes in this book discuss the exhaustion at the end of a long day’s work, the amazement at watching a seedling sprout, and the peace and happiness of time spent in reverie on a quiet bench.

Each quote in the book is written in a fun, different font, and I really enjoyed how the important words that the author wanted the reader to see were in pink, while the rest of the words were in green. This allowed the reader to see what they should take away from the quote, and I also thought that the different colors added an exciting element.

One quote that I enjoyed while reading the book was “Gardens are a form of autobiography,” by Sydney Eddison.

This quote spoke to me because it showed me that no garden is the same, and the garden you build speaks to the person that you are.

I would recommend this book to any gardener or non-gardener looking for a simple read about the highs and lows of gardening. o

By Carol J. Michel and Ty J. Hayden Publisher: Gardenangelist Books List Price: $9.99 Order Link: https://amzn.to/36JJgnD Reviewer: Jessica Kranz The Christmas Cottontail, written by Carol J. Michel and illustrated by Ty J. Hayden, is a fictional Christmas story about how a regular bunny was named the “Christmas Cottontail” by Santa Claus.

The story begins with the Christmas Cottontail talking about his job of how

BOOKreviews he creates a list of good gardeners and bad gardeners. Once this list is sorted out, he will fly out with Santa on Christmas Eve and plant seeds and bulbs in each good gardener’s garden.

Each year, the Christmas Cottontail will show how grateful he is for his job by telling his fellow workers the story of how he was given his title. He says that one Christmas Eve, he was starving and saw some carrots that were left for the reindeers to eat, and when he went to go eat them, Santa saw him, took pity on the bunny, and decided to take him back to the North Pole. Santa decided to train him to properly scatter seeds and plant bulbs, which is how he became the Christmas Cottontail.

This book is a great story to tell any child or gardener over the holidays, and it is also accompanied by terrific illustrations that enhance and help the reader visualize the story. If you are looking for a new holiday book, this should be the one you read next. o Jessica Kranz is a senior broadcast journalism major at the University of Maryland, College Park and an editorial intern at Washington Gardener this autumn.

Crops in Tight Spots

By Alex Mitchell Publisher: Kyle Books List Price: $24.99 Order Link: https://amzn.to/2rQJpXh Reviewer: Erica H. Smith I have read a lot of books about planting edibles in small spaces and containers. This one is a decent example

of the genre. It’s pretty and well-written, and has interesting suggestions for plants and projects that all look possible and fun.

I should note up front that this book was published in the UK and is written in British English. This shouldn’t be a problem for most American readers, but if you tend to be startled at being asked to start your aubergines in bog-standard fruit punnets and label them with lolly sticks, or to harvest courgettes with your secateurs next to the wormery in the side return, then it may not be for you. It’s also worth noting that the recommended products and suppliers won’t be accessible in this country; of course, we have equivalents for most of them, but some of the advice about “composts” (a.k.a. potting mixes) may be confusing.

The book covers plants and projects best suited to indoor growing, ledges and sills, terraces and courtyards, roofs and balconies, small in-ground gardens, and “other awkward spots.”

There’s a chart showing which plants are recommended for which situations, and lots of suggestions about appropriate containers. Even in a very small growing area, you could fit in many edible plants following these guidelines.

(You will be watering your containergrown plants frequently, especially in our hot summers, but that’s a good way to get to know your garden intimately.)

Succession planting maps for a small backyard garden take up several pages and are a useful guide.

One thing I appreciate in this book is how each plant is introduced with a level of difficulty, which include “easy,” “moderate,” and “ambitious.” I like that final descriptor better than “hard” or “challenging.” Occasionally, a difficulty level doesn’t fit with my experience, but that’s mostly a matter of climate difference. All the plants are worth trying!

I also like the emphasis on recycling; most of the suggested containers and materials are either reused or reusable.

Perhaps you’ll come away from this book wanting to grow beans in your alley, or harvest potted cocktail ingredients from shelves, or plant herbs in tin cans attached to a trellis, or start a crop of mushrooms under your bed.

You might even want a wormery. o

Gardener’s Guide to Compact Plants: Edibles and Ornamentals for SmallSpace Gardening

By Jessica Walliser Publisher: Cool Springs Press List Price: $24.99 Order Link: https://amzn.to/34k8ya1 Reviewer: Erica H. Smith While the gardening industry continues to expand, our gardens are shrinking.

Between millennials who can’t afford houses, older people who are downsizing, real estate trends for smaller yards, and everyone’s busy lives, many of us are trying to grow more plants in less space. That means there’s a real need for books like this one. Jessica Walliser writes smart, useful guides to solving gardening problems, and this is no exception.

The biggest section of this book is taken up by profiles of specific shrubs, trees, perennials, and edibles that can be considered “compact.” This list could have expanded into an encyclopedia; to fit into a compact volume, it’s necessarily limited to a few best examples. All of them should be available from local retailers or online sources.

Profiles include common and botanical names for the specific cultivars, mature dimensions, hardiness, ideal sun conditions, bloom or harvest times, and details of appearance and care. What “compact” means for all these plants naturally varies somewhat. Trees are judged more by width than height; all cultivars mature to a lesser size than others in their species, but obviously Book Reviews continued on page 16 DECEMBER 2019

a basil plant will be smaller than an apple tree, and a coneflower miniature compared to a hydrangea. The one omission I see in these profiles is plant origin; in most cases, North American natives are described as such in the notes, but if you want to put together a garden of natives, you’ll have to read carefully and then do more research.

If you want more plants to choose from, review the sample gardens contributed by various garden designers—also a great resource if you prefer to start from a template. There’s also a chapter listing plants that solve particular gardening challenges, such as a boring winter landscape or not enough pollinators.

Helping with plant selection is terrific, but I think the best parts of this book are the introductory chapters that talk about defining, selecting, and maintaining compact plants; they answer the basic how, what, and why questions about this sort of garden. One of the sections I liked best was “Where do small-statured plants come from?” with its explanations of selective breeding, vegetative propagation of genetic variants, grafting, and the “fake-out” of plant growth regulators. How do you shop for these plants? How do you plant them and take care of them?

Lots of questions are answered with easy-to-read, scientifically up-to-date information.

If you’ve got a small garden to start or renovate, this book will guide you through that project. Even if your garden is large, it’ll help you squeeze in a few more plants! o The Half-Hour Allotment: Timely Tips for the Most Productive Plot Ever

By Lia Leendertz Publisher: White Lion Publishing/Royal Horticultural Society List Price: $20.00 Order Link: https://amzn.to/2YVbdG7 Reviewer: Erica H. Smith Let’s just get the language issue out of the way up front. This is two books in a row I’ve reviewed that are published in the UK and use British English; we’re still dealing with aubergines and courgettes here, but I’d say you’ll trip over them less in this book. The title itself could be a mystery to some, however.

WASHINGTON GARDENER DECEMBER 2019

If you don’t know, an allotment is what we’d call a community garden plot, and this book is all about how to maintain yours (or your home garden) efficiently.

It’s very common to take on a plot of land with good intentions of producing healthy, delicious food, and to end up with a weedy, discouraging mess. I do a talk on this same topic, so I was interested in how this author approaches it. Indeed, she’s given us a practical method that should lead to success: Plan on spending two and a half hours a week in your allotment, divided up however works best for you. The weekday half-hour provides the title, but if you only have time on weekends, you can make that work, too. Whenever you finish up your tasks for one day, make a plan for what you’ll do the next time, so you can be prepared with the right supplies and get started right away.

Don’t take on too much at first; If your plot is large, don’t be afraid to cover some of it until you’re ready to plant.

Choose your plants carefully, and don’t plant too little or too much. All great advice!

The only hesitations I have are the usual ones when a book is written far from my usual digging ground. You can throw out most of the information about pests—we sure have them, just different ones—and a lot of the advice about best varieties of crops. If you have a community garden plot, you’ll need to adjust some of the recommendations to adhere to your group’s rules.

For example, in the Montgomery Parks

garden I belong to, we can’t install permanent structures like sheds, or solidmaterial paths, and we must garden organically (which this book advises in most cases, but not exclusively). It’s easy enough to consider and then skip these sections, just as you pause over the occasional piece of fleece (floating row cover) or mange tout (snow pea). But that adds up to a lot of pages you’re not likely to refer back to.

In general, though, the recommendations are good and translatable to local circumstances. I did spot a few outof-date dictates—no, it’s fine to leave water drops on leaves during the day; the sun won’t burn them, and in fact, you should avoid watering in the evening because of fungal diseases—but that’s made up for by bits like the clear, sensible advice about companion planting with no trace of folklore or woo-woo. As a community gardener, I appreciate the sections about getting along with neighbors and how to keep kids entertained in the garden, and there’s a chapter about how to manage as a new gardener in your first year that’s extremely helpful. There are also a lot of cool photos that make me wish our garden looked more British and I could put up a cute little shed, although I can’t spare that in 400 square feet anyway.

I’d recommend this book to anyone who has taken on a plot that feels too challenging, as long as you’re willing to pick and choose from among the morsels of guidance. Encouragement, especially to new gardeners, is more precious than tomatoes. o Erica H.

The conference was an opportunity for researchers, practitioners, educators, and planners working in cities all around the world to come together, exchange ideas, and create partnerships. With urban populations surpassing 50% worldwide, proper city planning, specifically enhancing green space, is a priority. This conference highlighted cutting-edge urban forestry and urban planning research to inform practitioners and policymakers.

The day kicked off with a welcome breakfast and time to meet exhibitors and sponsors, including the Washington Gardener.

Dr. Michael Dirr was the opening keynote speaker and discussed “In Search of the Next Great Tree.” He is a professor emeritus at the University of Georgia and author of numerous books, including the Manual of Woody Landscape Plants.

Dirr provided an educational and upbeat journey across the many types 18

of trees around us and which ones he has encountered, along with some fun stories that go along with them. He notes that you do not breed them, but you find them. He also said, “If you see it, get it. And if you can’t get it, steal it.”

He provided some information on where to discover new genetics, such as forests, fields, campuses, and golf courses. Dirr also talked about the different sources of variation, which include seedlings, sports/mutations, traditional breeding and selection, chemicals, radiation, and genetic manipulation.

Promising tree selections he highlighted included a Mongolian Oak (Quercus mongolica) that he called, “rare, but beautiful.” He said he had yet to “crack the nut on propagation.”

He shared an American Beech (Fagus grandifolia) selection that is “more compact and upright than the typical species.” He said that Schmidt Nursery will soon introduce it to the trade.

Another highlighted tree was a Japanese Zelkova (Zelkova serrata) that he found on Cape Cod and described as “the most impressive Zelkova I have observed.”

He concluded with his final slide in his presentation, stating, “In pursuit of the next great tree, the journey is forever.”

Urban Planning Issues

The “Planning Green Spaces” section within Session One featured roughly 20-minute talks from three presenters, followed by a panel where audience members could ask questions.

Ken Ray made a presentation titled “Moving Beyond Complete Streets: Trees in Urban Landscapes.” Ray is deputy director of landscape architecture for the Toole Design Group. He had us consider “four principles to change our approach to transportation design and how trees fit in.” These principles included: design for people, integrate green infrastructure, design from the outside-in, and start with the trees and they won’t be left out. Ray also provided pictures of streets across the country (including some in Boston, New York, St. Paul, Virginia Beach, and more).

The second presenter was Kimberly Burrowes, a technical assistance specialist with the Urban Institute. Her presentation was titled “Reflecting Community Priorities in Sustainable Park Planning.” She talked about parks, how they can be better used, and how we can benefit from them.

She had us consider the fact that onethird of Americans do not have a park within a 10-minute walking distance

GREENliving of where they live. She stressed the importance of having accessible parks and how they should include input from the community. She also included three strategies for engaging the community to improve parks: community ownership, community advisory boards, and equitable programming.

The third and final presenter was Louis Thomas, a project specialist for urban planning at the Center for Sustainable Development and Resilience at the University of the District of Columbia, on “Great Streets Without Trees: Assessing Quality Over Quantity in Urban Tree Canopies.” He brought up questions of “How are we managing green spaces?” and “Where is the appropriate space for trees?”

Citizen Participation

Session Two included a section on “Engaging and Retaining Volunteers,” with three presentations followed by a panel with the presenters.

Trinity Pierce, stewardship coordinator of the Chicago Region Trees Initiative (CRTI), presented on “Empowering Citizens to Expand the Chicago Region Canopy by 2050.” Pierce stressed the importance of having clear goals and went into the goals of CRTI, which include increasing the Chicago Region’s Tree Canopy, Reduce Threats to Trees, Enhance Oak Ecosystems, and Inspire People to Value Trees.

The second presenter was Jeanne Braha, Rock Creek Conservancy executive director. Her presentation was titled “People-Powered Restoration.”

Braha explained the concept of working from the outside in and the importance of considering that there is unequal access to green spaces when thinking about recruitment.

Laura Schatzmann, a project specialist at the Center for Sustainable Development and Resilience, had a presentation titled “Engaging Citizens and Enriching Programmatic Environmental Stewardship with UDC Master Naturalist Program.”

Schatzmann talked about why DC needs a Master Naturalist Program, along with activating and engaging within the program. Some next steps include a DC Master Naturalist meeting in spring 2020 to connect local

communities and create enhanced curriculum.

Quantifying the Benefits of Trees for the Bay

During Session Two, ecologist Nancy Sonti and Smithsonian researcher Amy Hruska presented their studies to the attendees on the benefit of trees, also referred to as forest patches, in the Chesapeake Bay area.

Sonti presented first, and discussed the importance of how trees can mitigate stormwater. As more infrastructure is built, we lose more forest patches, leading to quantities of water flowing into local bodies of water, which carries pollutants and toxic elements, she said.

A lot of this polluted/toxic stormwater is flowing into the Chesapeake Bay, affecting the water quality. Through Sonti’s studies, she found that protecting forest patches can prevent this from happening.

Sonti studied stormwater infiltration and transpiration on many forest patches in the Baltimore area to understand whether a single tree, cluster of trees, or closed canopy absorbed more stormwater runoff. She found that single trees absorbed the most water because clusters and canopies tend to have overlapped leaves, so it is more difficult for water to penetrate through and reach the ground. Sonti concluded her presentation by telling the audience about the importance of protecting the forest patches they live by and that they should plant a single tree in their garden opposed to planting shrubs because of the benefits they provide.

After Sonti’s presentation, Hruska discussed her studies of forest fragmentation in the Chesapeake Bay watershed, which has an area of 64,000 miles. She began her presentation by showing the audience how the watershed is currently ~50 percent forested, when it should be at 95 percent.

Hruska also discussed the importance of forest patches, but her study specifically focused on their impact on habitats and global change mitigation.

Unfortunately, since her study began in July 2019, she did not have any findings to present yet, but she discussed how they are looking to find out how urbanization has altered forest cover, and how urban forests can benefit biodiversity and ecosystem services in the watershed.

The presentations concluded with a panel discussion, and the audience was able to ask any questions they had for Sonti and Hruska.

The day ended with a final keynote by Sonja Dümpelmann entitled “Seeing Trees and the Forest.” She described the history of street tree plantings in the cities of New York and Berlin, and the changing relationship between trees and humans in the urban environment. o Taylor Markey and Jessica Kranz are seniors at the University of Maryland, College Park majoring in journalism and are editorial interns at Washington Gardener.

Seed Exchange Details

If You Have Seeds to Bring and Swap

Please package them in resealable plastic zipper or wax sandwich baggies. Put an average of 20 seeds per baggy—more for small seeds like lettuce, fewer for large seeds like acorns. Label each baggy with a white sticker (such as Avery standard 5160 address label sheets) giving all the information you have on the seeds. If known, include the plant’s common and scientific names; its soil, sun, and watering needs; and, its origins—where and when you collected the seeds. If you don't know all the information, that is okay; just provide as much as you can.

Yes, you can bring unused or opened commercial seed packs.

What If You Don't Have Any Seeds to Swap?

Come anyway! Even if you don’t have any seeds to trade, you are welcome to attend.

We’ll have plenty of extra seed contributions on hand and many attendees will be there just to learn, network, and prepare for next year’s seed collecting.

Education Program

Expert speakers from the local gardening community will give short talks on seed collection and propagation tips. There will be ample time for individual Q&A throughout the program with the featured speakers, and invited experts as well.

St. Mary’s College Awarded $30K Grant for Campus Community Farm

Barry Muchnick, assistant professor of environmental studies at St. Mary’s College of Maryland, was awarded a $30,000 grant from the Community Foundation for Greater New Haven, one of the oldest and largest community foundations in the United States, on November 12. The funds will be used to support research, development, and implementation of new programming at the Kate Chandler Campus Community Farm, according to St. Mary’s College of Maryland.

Muchnick said the “Kate Farm” is a special place to grow food and the grant will deepen and expand the ways the farm serves all St. Mary’s students, along with the surrounding community.

The farm educates students about sustainable agriculture and empowers people to become engaged environmental stewards.

Not only does the farm grow food and provide an impactful learning experience, but it also “…offers co-benefits including improved well-being through healthy eating, increased contact with nature, and a strengthened connection to our rural landscape and history,” Muchnick said.

Muchnick also plans to use the grant to help improve infrastructure, launch a new mini-grant program to support farmbased scholarly and creative projects, and develop new course offerings and a strategic plan for the farm’s future. The assistant professor hopes that this will engage all St. Mary’s students, and not just environmental studies majors. o

Rain Gardens Completion

The Golden Triangle Business Improvement District (BID) announced the completion of 11 new rain gardens and 10 expanded tree boxes along 19th Street NW, at an inaugural planting ceremony on December 9. The project adds more than 4,500 square feet of green space, lining two full blocks on one of the most-vibrant corridors in Washington, DC’s central business district.

The initiative is funded by the U.S. Environmental Protection Agency (EPA), Golden Triangle BID, and DC Department of Energy & Environment (DOEE).

Additional support is provided

by Pepco, Rockrose Development Corporation, The Tower Companies, Carr Properties, OTO Development, Wawa, and Population Services International.

“We are proud to demonstrate that it is possible to retrofit a dense, built-out urban environment with green infrastructure,” said Leona Agouridis, executive director of the Golden Triangle BID. “I would like to thank our partners, public and private, for their support of this project over the past years. The 19th Street rain gardens contribute to the environmental sustainability of the metropolitan area and continue to transform the Golden Triangle into the model central business district of the future.”

The new rain gardens can capture and filter up to 43,000 gallons of polluted runoff per storm, reducing the risk of local flooding and helping to clean waterways.

“EPA is pleased to be a partner in this project that has much to offer for the area’s environment, economy, and quality of life,” said EPA Mid-Atlantic regional administrator Cosmo Servidio.

“Controlling stormwater runoff through green infrastructure improves local waters and the Chesapeake Bay.” This project brings the natural environment directly to the thousands of workers, visitors, and nearby residents who walk down 19th Street every day.

The BID has planted 33 trees and more than 400 native plants specially selected for their ability to absorb water and survive long dry periods between storms.

Several of the plants were chosen for their habitat value for pollinators like bees and butterflies.

This initiative is the latest in the BID’s history of green infrastructure projects.

The BID previously built six rain gardens and converted 12,000 square feet of asphalt and concrete to green space. The implementation of these

sustainability programs contributed to the BID’s LEED certification earlier this year. The Golden Triangle was awarded LEED Platinum—the highest level of LEED certification —by the U.S. Green Building Council. It is the first BID in the world to be certified through the LEED for Communities program.

The rain gardens—which are part of the Golden Triangle’s Gold Is Green program, the BID’s portfolio of sustainability initiatives—have been added to both sides of 19th Street NW between K and M Streets. They join four existing rain gardens at the corners of 19th and L Streets and built by the BID in 2014. To highlight 19th Street as a green corridor, the Golden Triangle has installed Gold Is Green light pole banners and decals on trash and recycling receptacles. Five new educational signs explain how rain gardens work have been installed. o

Fantastic Fungi Screening.

On Thursday, December 12, the AFI Silver in downtown Silver Spring, MD, hosted a sold-out screening of “Fantastic Fungi.” The film is “a consciousnessshifting documentary that takes us on an immersive journey through time and scale into the magical earth beneath our feet.” Featured in the film are scientists and mycologists like Paul Stamets, along with best-selling authors Michael Pollan, Eugenia Bone, and Andrew Weil.

The director. Louie Schwartzberg, participated in a panel discussion after the film. o
