Here is our comprehensive garden task list for gardens in the greater DC metro region for December 16-January 15. Your additions to this list are most welcome: • Keep watering your poinsettias and give them plenty of light. Ensure they are away from drafts and that the pots drain freely. • Last chance to plant bulbs or if you have waited until the ground is frozen, pot them up for forcing indoors. • Gather holiday greens. Some, like holly and boxwood, benefit from being pruned by growing thicker. • Feed birds and provide them with a fresh water source. • Check houseplants and any plants you brought indoors for the winter, for insects. • Provide some special protection to tender or early flowering plants like Camellias. • Stake newly planted large trees or shrubs to protect them from winter winds. • Check any bulbs, corms, tubers and bare root plants in storage for rot or desiccation. • Apply scale and dormant oil treatment to evergreens. • Spread ashes from wood fires on your vegetable beds. • Keep succulents and cacti on the dry side. • Water your cut Christmas tree daily. • Gently remove layers of snow from evergreens with a broom. • Start organizing your pile of incoming garden catalogs. • Keep an eye out for bark damage from rabbits and deer. • Spray broadleaf evergreens with anti-desiccant to prevent dehydration. • Use the branches from your Christmas tree as bedding mulch or as a wind-break. • Keep watering newly planted trees and shrubs as needed. • Cover strawberry beds with straw or pine needles. • Prune stone fruit trees like cherries, plums, and peaches. • Clean, sharpen, and store your garden tools. • Reduce fertilizing of indoor plants (except Cyclamen). • Set up a humidifier for indoor plants or at least place them in pebble trays. • Continue to rotate houseplants to promote even growth. • Attend a local garden club meeting. • Start new indoor plants from cuttings -- try an easy one such as violets. • Check the plants under tall evergreens and under the eaves of the house to see that they have sufficient moisture. • Weed. Weed. Weed. • Pick a budding gardener on your gift list to give some inspirational garden books and magazines then watch them blossom. • Store your fertilizer and seeds in rodent-proof containers. • Do any filling and grading around your yard. The soil will settle during the winter months. • Vent cold frames on sunny days. • Avoid walking in frozen planting beds. • Remove and destroy gypsy moth egg masses. • Clean your gutters. • Prune maples, dogwoods, birch, elm, and walnut -- if needed. • Bonus Tip: Some alternatives to de-icing salts include sand, beet juice sugars, light gravel (grit), or non-clumping kitty litter. Using de-icing salts around driveways and sidewalks can harm your garden plants and turf. Have a wonderful holiday season!

Maryland Native Plant Society White Oak Library New Hampshire Avenue Silver Spring, MD www.mdflora.org

• Sunday, December 19, 10:00AM3:00PM WINTER SOLSTICE CELEBRATION Sponsoring Organizations: Maryland Native Plant Society, Virginia Native Plant Society’s Potowmack Chapter, and the Arlington Regional Master Naturalists. The Travilah Serpentine Barrens is the Mid-Atlantic region’s stellar example of a globally-rare forested serpentinite community. This vegetation type once comprised many thousands of acres in the area of Montgomery County west of Potomac and Rockville, with about 1,000 acres of this rare local landscape preserved today. Serpentinite is an ultramafic rock derived from magnesium-rich silicate materials that typically weathers to a soil that is high in magnesium and iron. The Travilah serpentinite is dark grayish green and closely underlies the surface, frequently outcropping throughout. Soils of this type are fairly nutrient deficient and produce a somewhat stunted vegetation characterized mainly by oaks, hickories, pines, and heaths, though plants of the Rosaceae, Cyperaceae, Poaceae, and Lamiaceae, among others, are also prominent. Much of the forest at the Travilah site is old-growth, despite the relatively short height of the canopy trees. The canopy is predominately white, northern red, and post oak; sweet pignut, mockernut, and pignut hickory; and shortleaf and Virginia pine. Prominent understory plants are eastern red cedar, blackjack oak, sweet crabapple (Malus coronaria), a variety of hawthornes (Crataegus spp.), black haw, dogwood, fringe tree, and others. Some sections of the forest floor are densely vegetated with colonies of ericaceous plants of the Heath Family, such as deerberry, lowbush blueberry, and black huckleberry. Other are extensive glades of graminoids (grasses and grasslike plants) and wildflowers, many of which are regionally rare. We’ll also see many grasses and plants typical of meadows and prairies and a rare Upland Depression Swamp. Wear sturdy shoes and bring lunch or snacks and water. Most of the walk traverses fairly open woodland, open glades, and grassy areas over gently rolling uplands, though some trails may be gravelly to moderately rocky. We’ll probably walk maybe 2 to 3 miles maximum throughout round trip - and the way back to the cars will be pretty clear for those who want to duck out early.

Gardening by the Rul by Kathy Jentz

We are almost starting the second decade of the 21st Century and many of the old gardening rules we have lived by are being turned on their heads. New gardeners often hear conflicting and misleading advice. Experienced gardeners may need a fresh perspective and to evaluate their old habits. With a look towards the coming new year, here are five old rules we no longer need obey and five new to add to our collective garden rulebooks.

5 Old Garden Rules to Break:

1. Turf is King – The green suburban lawn is no longer the ideal or the goal. Turfgrass is one of the most wasteful of our natural resources, not to mention high time-consuming to maintain by the owner. Today’s gardeners are looking at other groundcover choices including expanding shrub borders, installing edible beds, and hardscaping pathways. 2. Spray Away – Chemicals used to be the answer to all your garden’s ill, but along with killing grubs they were also taking a toll on your own health and that of the local environment. The key words today are diagnosis first, then exploration of chemical alternatives second. Living with some imperfection is very 21st Century. 3. Dig and Double-Dig – Just a few years ago, we were all urged to dig in that compost and fertilizer to really work it in. Researchers have shown that we are doing far more damage to the soil’s structure than any benefit. In addition, we are turning up new weed seeds that would otherwise be dormant. Stop digging and start layering on organic materials to decompose and work their own way in. 4. Fertilize Everything – Fertilizer spreaders are joining the VCR and transistor radio in scrap heaps. Most fertilizer applied on and around plants washes away and into our local streams. Today the word is to feed the soil, not the plants. Healthy soil promotes strong growth. Add your own home-made compost and organic mulch to your beds to provide nutrients. 5. Water Copiously – The oscillating sprinkler is another dinosaur headed for the junkyard. Good gardeners know to group their plants by their watering needs and to use drip irrigation not overhead sprinklers or hoses.

5 New Garden Rules to Make:

1. Use Local Natives – Research plants that are local natives and naturally grow in your home’s ecosystem. If you have a shady, forested yard, choose plants native to that environment. If you have a wet area of your lawn, redesign it as a rain garden with moisture-lovers. (Note: just because it is labeled a “native” does not mean it is from our area nor that it is suitable for your yard’s micro-climate. Do you research before buying and planting.) 2. Attract Wildlife – Birds, bees, and other creatures can naturally pollinate and spread the fruits of your garden labor. Encourage bugs that prey on other insects and can act as pest managers for you. 3. Plant en Masss – Gardening is one area in your life you can go crazy with mass quantities and the more you use, the better it looks. A bed of 300 daffodils and a grouping of 100 daisies is feast for the eyes. Go ahead and indulge. 4. Beware of Mature-Sizes – Trees and shrubs can quickly eat up your gardening real estate. Think twice before buying those large-growth plants and exactly where you will plant them to avoid having to constantly prune them or worse still, kill them, when they overgrown they space you assign them. 5. Grow What You Love – So what if your neighbors find your plant choices old-fashioned, boring, or garish. Look at your garden through your own eyes and don’t worry about what others think. It is yours and you make the rules – and don’t ever let anyone ever tell you otherwise.

Magazine Excerpt: Russian Sage - Perennial Pleasure by Kate Tyndall

A real workhorse in the perennial garden is the Russian sage, Perovskia. Neither Russian nor a true sage, this is a tall, handsome woody sub shrub with a wide spreading habit and masses of violet-blue flower spikes from mid summer into fall. Attractive as it is, Perovskia is often overlooked by gardeners, even by those who should know better — and I include myself in this latter group — in favor of showier shrubs or newer perennials. The Russian sage will simply go about its business year after year, requiring only a place in the sun and decently drained soil. It will not demand excess watering in torrid summers, when other plants wilt and collapse, nor will it fall prey to insect pests or fungal diseases. In the garden as in life, the squeaky wheel gets the grease, and Russian sage simply rolls along without complaint, causing no problems but receiving far too little attention for its solid performance and good looks. Bees, however, love the sage’s tiny, tubular flowers and you will often find the plant the buzzing center of great bee activity in your garden. Many gardeners report Perovskia is a real draw for hummingbirds, but alas, I cannot confirm this, since hummers seem to boycott my garden, regardless of my attempts to woo them. Russian sage is a member of the mint (Lamiaceae) family and its slender, serrated grayish-green leaves and stems give off a pungent odor (smelling of a mix of menthol and lavender) when bruised. This shrubby perennial is found from Afghanistan to Tibet, where it usually grows in open, rocky soil. Its botanic name honors the 19th-century Russian general and statesman V.A. Perovski, who perhaps saw it growing on the campaign trail when he led his army into Afghanistan. Russian sage requires at least six hours of sun a day and the more sun it can get, the happier it will be. Although it prefers a lean soil, regular garden soil is fine. If yours is heavy, unamended clay, you should give this perennial a pass unless you can grow it in a raised bed. Don’t fertilize it — doing so will encourage leggy growth and....

Washington Gardener Magazine’s 6th Annual

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 cleome, fewer for large seeds like acorns. Then 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's okay, just try to provide as much as you can. Yes, you can bring unused or opened commercial seed packs also.

What If I 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

from each of the category tables (if desired). After the initial seed swap is complete, attendees are free to take any of the left over seeds and to trade seeds with each other. Dividing of packets is encouraged and extra baggies with labels will be on hand for that purpose.

Schedule

What Types of Seeds?

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. (Note: This schedule is subject to change.) 12:00-12:30 Registration check-in 12:30-12:40 Introductions 12:40-1:20 Heirloom Seed talk 1:20-1:40 Gardening talk 1:40-2:00 Gardening talk 2:00-2:15 Snack break and room reset 2:15-2:30 Seed swap preview time 2:30-3:00 Seed swap 3:00-3:30 Photo Contest winners 3:30-4:00 Door prizes and closing talk

How Do We Swap?

As you check-in, staff will collect your seeds and place them at the appropriate seed category tables. You will be assigned a random seed swap number. There will be a short period for attendees to preview all the seeds brought in and available for swapping. Then, you will be called in by your number to pick a seed pack

Seed swap categories will include natives, edibles, herbs, exotics, annuals, perennials, and woodies (trees/shrubs). If you can presort your seeds in advance into whichever of these seven major categories fits best, that would help us speed up the process on the swap day.

Door Prizes! Goodie Bags!

All attendees will receive a goodie bag at the seed swap. The bags include seeds, publications, and garden items donated by our sponsors. In addition, we have some incredible door prizes to give away especially for area gardeners. If your organization would like to contribute seeds or garden-related products for the goodie bags and door prizes, please contact Kathy Jentz at 301.588.6894 by January 25.
