February Garden To-Do List Spotlight Special Urban™ Columnar Apples

New fruit tree introductions that yield great tasting apples in a tiny space. Urban™ Columnar Apple trees are loaded with fruiting spurs along the main leader, and branches are short and upright, producing straight, uprightgrowing, cylindrical apple trees. Plant Urban™ Columnar Apples in the ground, or transplant to large containers coordinated with home and architecture and enjoy moving them around as desired. Romantic apple blossoms in spring will enchant homeowners, apartment dwellers, condo owners, suburbanites, and those short on space. Urban™ apple trees mature at 8 to 10 feet tall but less than two feet in diameter (!), and are extremely healthy and disease resistant. When grown in full sun expect full-sized fruit the first year from planting, so long as there are two or more varieties for cross pollination. As trees mature, the yield of apples will increase. Be sure to maintain fertility levels for good growth and yields. The Urban™ Columnar Apple Series was developed by Dr. Jaroslav Tupy of the Czech Republic, a member of the Garden Debut® (www.GardenDebut. com) consortium of growers, breeders, retailers, and marketers. Tupy’s choice of four varieties ensures a wide selection of flavor, plus good cross-pollination and fruit set: • Tasty Red™ is a bright red apple with a sweet, juicy flavor • Blushing Delight™ produces a blush of reddish green fruit with a slightly sweeter taste • Golden Treat™ greenish-gold apples are tart in early fall, but get sweeter the longer they are on the tree • Tangy Green™ lime green apples add a crisp, tart flavor to the series. 2

Here is our comprehensive garden task list for gardens in the greater DC metro region for February 16-March 15. Your additions to this list are most welcome: • Cut some branches (forsythia, quince, bittersweet, redbud, willow, etc.) for forcing indoors. • Put suet out for birds. • Keep bird feeders filled and provide a source of water. • Check outside plants and trees for animal (deer) damage. • Mist indoor plants and set up pebble trays to increase humidity. • Rejuvenate holly bushes and boxwood with a hard pruning. • Plan landscape design projects. • Check evergreens for sign of desiccation. • Start seeds of cool season vegetables and flowers. • Keep ice melting chemicals away from garden beds. Use coarse sand instead. • Prune any dead or diseased wood off trees and shrubs. • Fertilize trees, shrubs, and evergreens. • Prune roses. • Begin tilling beds (when the earth is dry enough to work - mot muddy) and work in compost. • Plant or transplant trees or shrubs including berries, roses, and evergreens. • Apply pre-emergent weed control like corn gluten. • Protect tender plants by covering them with some type of cloth material, if an unusually cold day or night is forecast. Be sure to uncover them if it warms up. • Weed. • Trim ornamental grasses such as liriope, mondo, and pampas. • Divide overgrown or crowded perennials such as daylily and shasta daisy. • Scan houseplants for insect activity. • Dust your house plants with a slightly damp cloth. • Clear out perennial beds of any dead plant parts and debris. • Clean and organize the garden shed. • Clean, sharpen, and oil the tools. If not done last Fall. • Walk your yard and check plants and bulbs for heaving and place them back into the ground. Cover with more mulch to prevent further heaving. • Apply dormant oil spray to ornamentals and fruit trees before dormancy breaks. • Check and tune-up power equipment (mowers and trimmers). • Build garden furniture. • Spread new gravel on paths. • Mulch bare areas. • Design new beds and gardens. • Pick up new gardening books and magazines for inspiration. • Start seedling indoors under grow lights. Some good choices to start early are peppers, artichokes, onions, beets, turnips, cabbage, kale, and leeks. • Put up trellises and tee pees for peas and beans to climb on. • Direct sow early, cool season crops as soon as ground soil can be worked. Good choices are peas, lettuces, mustards, onion sets, kale, and cabbages. • Start or turn your compost pile. • Do an annual soil test and amend soils as recommended. • Check for snow damage. Gently brush off snow weight, if you must. But better to let snow melt off on its own. • Have a wonderful 2012 growing season!

Early Season Bloomers for the Mid-Atlantic By Kathy Jentz, Editor of Washington Gardener Magazine It happens every winter. We gardeners hit “the wall” where we need want, need, crave just a little bit of spring. The best way I’ve found to cope with that special brand of cabin fever is to seek out as many early-blooming plants as I can to add to my garden. You can call them pre-spring or late-winter flowers, either way they are the first signs of life and a welcome relief from winter’s dull gray landscape. The following is a listing of plants in their order of bloom dates here is the greater Washington, DC region and Mid-Atlantic states. The bloom time may vary by variety, your location, and the local weather patterns. In general though, you can rely on these bloomers coming out well ahead of the traditional start of spring on March 20. • Fragrant Wintersweet (Chimonanthus praecox) • Fragrant Viburnum (Viburnum farreri) • Sweet Box (Sarcococca humilisox) • Camellias (Camellia japonica) • Winter Jasmine (Jasminum nudiflorum) • Snowdrops (Galanthus nivalis) • Heather (Erica carnea) • Winter Hazel (Corylopsis) • Lenten Rose (Helleborus orientalis) • Daphne (Daphne odora) • Edgeworthia (Edgeworthia chrysantha) • Common Periwinkle (Vinca minor) • Spring Beauty (Claytonia virginica) • Witch Hazel (Hamamelis vernalis) • Winter Aconite (Eranthis hyemalis) • Crocus (Crocus spp.) • Dog Violet (Viola labradorica) • Flowering Apricot (Prunus mume) • Checkered Lily (Fritillaria meleagris) • Glory of the Snow (Chionodoxa forbesii) • Daffodil Rijnveld’s Early Sensation (Narcissus) • Dutch iris (Iris reticulata) • Daffodil ‘February Gold’ (Narcissus) • Redbud (Cercis canadensis) • Forsythia (Forsythia spp.) • Primrose (Primula spp.) • Daffodil ‘Tete a Tete’ (Narcissus) • Flowering Cherry (Prunus ‘Okame’ ) • Bradford Pear (Pyrus calleryana) • Quince (Cydonia oblonga)

While you are planning your garden purchases for the year, be sure to remember to plant a few of these late winter blooming beauties to give you that promise of spring.

The Garden Leader of the xeric gardens at JCRA, Charlie will show us where this open-door plant philosophy has led in the xeric gardens, and tell us about some of its history. 6

Early attempts with xeric plants met with mixed success; even so, some specimens have persisted for more than twenty years. Beginning in late 2006, the JCRA began an expansion of its xeric gardens, with an emphasis on proper bed preparation to improve long-term plant survival. Several years later, a wide variety of plants from the U.S. Southwest, the Mediterranean, South America and Australia have thrived, providing blooms during every season, as well as structural interest throughout the year. Charlie says, “We’ll see the many successes-- along with an unshrinking examination of a few of our duds-- as we take a wartsand-all photographic tour.” Event details: www.pvcnargs.org. • Wednesday, February 22, 7:30pm Growing and Showing Vegetables The Beltsville Garden Club will hold a general meeting in the cafeteria of the James E.

A Special Visit to the National Ag Library

Washington Gardener Magazine is hosting a tour day of the National Agricultural Library in Beltsville, MD, for local garden clubs and select guests on Sunday, February 26 from 1:00-4:00PM. The National Agricultural Library is normally open to the public only during regular business hours, so this is a special opportunity for those who work full-time or those who are not in the DC area to travel to town for it.

Magazine Excerpt: Radiant Radishes by Elizabeth Olson

Small, red, globe-shaped radishes are a favorite selection among school teachers who are tasked with engaging young students with the wonders of vegetable gardening. Unlike the most popular vegetables (tomatoes and sweet corn) these radishes can be planted and quickly grown to harvesting size within the academic year. In fact, they can be grown with great success in both the fall and spring semesters. These small radishes are also called spring radishes and can be harvested in as little as 21 days.

The large roots of Asian-style cultivars, also known as daikon, can be made into pickles. (Daikon radishes need about 60 days to reach harvesting size.) Radishes originated in Asia, have the classification Raphanus sativus, and are a part of the Brassica family of vegetables. They have been widely grown in Europe for many centuries and were prominent in early American gardens. Barbara Melera of the D. Landreth Seed Company says that radishes in general are too often ignored by modern American gardeners, even though they are among the easiest and least-expensive vegetables to grow. Melera emphasizes the prominence of radishes as a nutritional mainstay in the 1700s and 1800s. Her personal favorite radish is the heirloom ‘French Breakfast,’...
