January Garden To-Do List

Spotlight Special Lifeberry® Goji berries (Lycium barbarum)

Two varieties of tasty, beautiful goji berries: Sweet Lifeberry® and Big Lifeberry® have been added to the line of Proven Winners® ColorChoice flowering shrubs. Grow superfruit in your own backyard! These extra-sweet fruit are perfect for snacking. Goji berries are easy to grow in full sun, although some staking may be necessary for maximum access to the nutrientrich fruit. A pollinator is not needed. These plants are hardy to USDA zone 5; heat tolerant to AHS zone 9. The plants tolerate some drought once established, but for best fruit set and quality, water regularly. Any well-drained soil will do. Goji berry plants will not be bothered by insects or diseases, but birds, deer, and raccoons may all find the fruit as appealing as you do. If you notice damage to the fruit or plant, or have a problem with these visitors damaging other plants in your garden, use a netting or repellent, particularly once the plant begins flowering and fruiting. Goji does not require pruning to grow well and produce fruit. However, you may find the plant is more manageable and easier to harvest when its lateral (horizontal) branches are lightly pruned to encourage branching and the production of vigorous new growth. Goji berries begin to ripen in early summer. They should be plucked off by hand when they are brilliant red and taste sweet. They come off the plant easily, without the need for pruners or a knife. For an abundant crop, apply a fertilizer formulated for flowering woody plants in early spring, just as new growth begins. Rose fertilizer is an excellent, readily available choice. The plants will be available at local nurseries and through mail order this year. 2

• Prune any dead or diseased wood off your small trees and shrubs. • Plant frost-tolerant trees. • Cut off the flower stalk on your amaryllis once flowers fade. Leave foliage to grow. • Keep poinsettias in a well-lit area — but out of direct sun and away from drafts. • Buy a few new house plants. • Fertilize only your winter-blooming house plants – such as Violets. • Give your house plants a quarter turn every few weeks. • Build a compost bin. • Repair your shed and repair/paint your fences. • Clean out your cold frame or build a new one. • Collect large plastic soda bottles to use as cloches. (A cloche is a clear, bellshaped cover used to protect tender plants from frost.) • Clean and refill bird feeders. • Wash and refill the birdbath or set out a shallow bowl of water in icy weather. • Check on stored summer bulbs and seeds. Discard any that have rotted. • Buy seeds and order plants from the new garden catalogs. • Prune summer bloomers such as hydrangeas, rose-of-sharon, crepe myrtles, and butterfly bushes. • Till and add organic matter to annual/vegetable beds. • Weed – especially look for fast-growing vines such as honeysuckle, autumn clematis, bittersweet, wild grape, Virginia creeper, and poison ivy. • Place a floating ball or a small plastic soda bottle filled two-thirds full with water and a tablespoon of salt in your pond to stop it entirely icing over especially if you have fish. When ice has formed, remove the ball/bottle by pouring hot water on it. • Insulate outdoor containers by wrapping with bubble wrap or landscape fabric. • Check that newly planted trees, shrubs, and perennials have not been heaved out of the ground due to freezing and thawing cycles. • Take hardwood cuttings from willow and dogwood to propagate them. • Look for evidence of pest or fungal damage throughout your garden. • Clean out your greenhouse and wash those windows. • Set out your live potted evergreens from holiday decorating in a protected outdoor space to harden them off in advance of their planting. • If we do get more snow in the DC area, gently dislodge snow from trees and shrubs with a broom to prevent damage to branches. • Start hardy herbs, onions, cabbage, pansies, and perennials. • Clean and tidy up pots and seed trays to a get good start in February. • Use leftover holiday greens and cut up tree branches to mulch beds and create wind-breaks. • Do not step on frozen soil in flower beds or lawns. • Keep all houseplants out of drafts and away from heat vents. • Use de-icer sparingly or use a nonchemical substitute such as sand, grit, fireplace ashes, or non-clumping kitty litter. • Volunteer at a local public or historic garden. • Paint a few terra cotta pots in spring-like colors. • Pot-up any leftover bulbs that did not make it into the ground by now and force them for indoor blooms.

Washington Gardener Magazine’s 8th 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.


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 Gardening 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 24.

Pruning Shrubs and Trees by Jim DeRamus

Step-By-Step Protocol 1. Look at the plant. Is it single trunk or multi-trunk. Are the branches spaced evenly or clustered? Examine it for structural defects and rot. Should it be low branched or limbed up? Is the bark damaged? Are limbs growing toward a structure? Keep these factors in mind as you prune! 2. Always remove dead and dying branches and twigs first. 3. Remove suckers and water sprouts, girdling roots and check for codominant leaders. 4. Remove one of the two crossing branches that are rubbing, or almost rubbing, throughout the tree or shrub canopy. 5. Remove branches growing inward toward the center of the tree or shrub toward other branches because they will become rubbing branches. 6. Check the branch spacing and if one is right above another, remove one. 7. Thin out dense areas along trunk and throughout the length of the limbs where branches are competing for space. 8. Tip prune for overall shape if necessary. If tip pruning cuts are even necessary, prune the offending branches of the shrub or tree to a bud growing in the right direction.

Bonus Tips for Plant Health While pruning your woody plant, continuously look for insects such as scale, sunken or discolored bark (cankers), and other abnormalities. Early detection and treatment will save you time and money. Never “top” a tree unless you are willing to pollard it, which means revisiting it every year to cut back the dense mass of whips (epicormic shoots) produced in the previous year. These whips are poorly anchored in the trunk, will often grow 10 feet a year and will tear out in high winds. Always plant a tree at the correct height, with the widened base (flare) of the trunk above grade, so you can see if girdling roots develop. Jim DeRamus is a horticulturist at M-NCPPC Montgomery Parks Brookside Gardens. He attended Montgomery College for an Associate Arts degree in Landscape Technology and the University of Maryland for a BS degree in Horticulture with the various awards that come with a 4.0 average. He has been employed locally in the field for the past 23 years and has been at Brookside Gardens since March 2005 where he manages the Formal Gardens. He will be giving a talk on “Pruning Deciduous Woody Plants” hosted by the Silver Spring Garden Club on Monday, January 21 at 8:00PM at Brookside Gardens, Wheaton, MD. The talk is free and open to the public. You do not need to register or RSVP to attend.

Washington Gardener Book Club 2013 Dates

With the success of our first Washington Gardener Magazine Book Club meeting last fall, where we discussed Founding Gardeners: The Revolutionary Generation, Nature, and the Shaping of the American Nation by Andrea Wulf, I have set a schedule of four book club selections/meetings for 2013 using the suggestions from our first meeting attendees. For our first 2013 selection, we will be reading The Orchid Thief: A True Story of Beauty and Obsession by Susan Orlean. (Bonus points for also watching the film, “Adaptation.”) I have reserved a meeting room at the Cleveland Park Neighborhood Library Room in the CPK Second Floor Large Meeting Room on Tuesday, February 12, 2013, from 6:00 PM to 7:30 PM. (We will move the location around to various DC library locations near public transit for each meeting pending library staff approvals, the location will be confirmed to you when you RSVP.) The room allows food and drink and you may bring your dinner and/or snacks to share. I have made sure that the DC library and other local library systems currently have several copies available for borrowing of The Orchid Thief. The book club meetings are FREE and open to anyone who would like to attend. Please RSVP to “WG Book Club” at I will be limiting attendance to 20. If you need to cancel, let me know ASAP so we can give your spot to someone else, should we have a wait-list. In case you like to read ahead, the other book club selections for 2013 are: • Second Nature: A Gardener’s Education by Michael Pollan • Farm City: The Education of an Urban Farmer by Novella Carpenter • Beatrix Farrand: Private Gardens, Public Landscapes by Judith Tankard I will announce the date for the next book club meetings after each previous meeting. We will meet roughly once each quarter.

Magazine Excerpt: Icebox Watermelons by Elizabeth Olson

One of the joys of the kitchen garden in summer is watermelon. It is often overlooked in discussions of what is growing, but it is arguably the crop that supplies the highest reward on hot days. Medium and large-size watermelons are what usually come to mind. They have long been the standard in markets and are regularly featured in whimsical seasonal decorations. They have also been elegantly depicted in paintings, including two by American artists William Merritt Chase and Margaretta Angelica Peale. A pink-fleshed watermelon is the subject of “Still Life with Watermelon” by Chase, dated 1869. A yellow-fleshed watermelon is the subject of “Still Life with Watermelon and Peaches” by Peale, dated 1828. Many cultivars of watermelons produce fruits that weigh 15 to 20 pounds or more and have thick rinds that make them safe to ship. Their major drawbacks for gardeners are that they can be somewhat difficult to manage in a vegetable patch, hard to slice, and awkward to store on a shelf in a refrigerator. Icebox watermelons solve these problems. The term “icebox” comes from these watermelons having a size small enough to easily fit in an icebox or refrigerator. Their rinds are moderately thin to very thin and are easy to slice. The plants are vigorous and productive, but the leaves are smaller and the vines are shorter than those of standard cultivars. The weight range for icebox watermelons is approximately three to 12 pounds. Fruits that weigh seven pounds or less are sometimes called mini-melons or personal-size watermelons. Icebox watermelons are pleasing to the eye in their own right, and they are as juicy and delicious as their larger counterparts. Different icebox cultivars produce fruit in an amazing array of flesh colors, including white, lemon yellow, orange, pale pink, and cherry red. Melon ball salads made from different colors of watermelon flesh are beautiful. Most rind colors and patterns vary from light green with dark green stripes to solid dark green. A few cultivars have rinds that turn yellow when the fruits are ripe... Want to learn more about this fascinating, growing icebox watermelons?
