Come and Celebrate Rooting DC’s 10th Anniversary — What a Blast!

rdc-tagline-logoLast year I attended Rooting DC for the first time and had a blast. Rooting DC is a free, all-day gardening forum that aims to provide education about urban food production and consumption to cultivate health and preserve the environment. There are many one-hour programs and an information fair with over 60 green businesses and non-profit organizations related to gardening and healthy eating.  Hosted by DC Greens, Rooting DC runs on a team of volunteers to make this a smooth and fun event. When I attended last year I collected a lot of information on local businesses, met well-known people in the gardening world, learned new gardening practices, and took lots of notes during the workshops.

Rooting DC opens at 9:00 am on Saturday, February 18. You can register in advance at the website or at the door. Although the event is free, a $10 donation is suggested. From 9:00 to 10:00 am you can visit the businesses at the tables in the atrium and get coffee and muffins/pastries.  Workshops begin at 10:00 am with the last one ending at 4:00 pm. There are four 1-hour sessions but within each session are about 15 to 16 topics in various classrooms. There is time to go from one session to the next and a break for lunch. I learned that it is best to download the schedule from the Rooting DC website to determine which session you want to attend before you get to the school. Map out where the classrooms are and where you want to go to take advantage of as many sessions as possible. Get to the room as early as possible to get a seat. Some are so popular that it is standing room only.

This year, Rooting DC is celebrating its 10th anniversary – it has grown from a small gathering of like-minded urban gardeners in 2007 to an annual event with more than 1,200 attendees. Fortunately, it is held in a high school with plenty of room, facilities, and even lunch options from local food trucks outside. Woodrow Wilson High School, 3950 Chesapeake Street NW, is within walking distance of Tenleytown metro station in Washington DC. Don’t forget to bring a bag for handouts, a notebook, and your phone so you can take photos and tweet about the event at #rootingdc. See you there!

Philadelphia Flower Show Celebrates Holland’s Contribution to Gardening and Landscape Design

Now is the time to think about planning your trip to the Philadelphia Flower Show, the nation’s largest and longest running flower show in North America. This year the show will run from Saturday, March 11, through Sunday, March 19. The theme is “Holland: Flowering the World.”  Celebrate the beauty and ingenuity of Dutch culture, from vivid flower fields to innovative eco-design. The Philadelphia Flower Show will transport guests to the rainbow landscapes of tulips, hyacinths, and daffodils and the cut-flower and bulb markets that have shaped Dutch history. The Flower Show will explore the innovation that has defined Holland’s approach to its unique landscape from windmills–one of the earliest uses of natural energy–to 21st century ecodomes and the Dutch Wave movement, which takes a natural and sustainable approach to landscape design. Leading designers from Holland, including Nico Wissing, Bart Hoes, Bart Bresser, and New Jersey born Carrie Preston will share their extraordinary floral and garden styles in major exhibits at the Flower Show.

The Flower Show is held at the Pennsylvania Convention Center, 12th and Arch Street, but you don’t have to drive by yourself. In the Washington DC metropolitan area, there are several nurseries, garden clubs, Master Gardener groups, public gardens, and park systems that offer day trips to the Convention Center. Green Spring Gardens, Brookside Gardens, and Greenstreet Gardens offer bus trips, contact them directly for more information. The Washington Gardener magazine offers two trips on different days: one from Behnkes Nursery and one from Silver Spring. Check out the various venues for date/time of departure, meeting locations, and prices which could include admission ticket, food, or entertainment. This is a walk-till-you-drop event: wear tennis shoes and bring your camera!

New Videos on Plant Propagation From Virginia Cooperative Extension Master Gardener Program

The Virginia Cooperative Extension Master Gardener Program has produced a series of 10 short videos on YouTube about plant propagation. Filmed in the Virginia Tech greenhouses, each video is about 4 minutes or less. Topics include seeding, transplanting, grafting, air layering, tomato grafting, and the many different types of plant division. These will be helpful as you begin to start seeds indoors now or if you are interested in dividing and multiplying your houseplants.

 

Starting Cool Season Veggies in Northern Virginia

Here is a handy chart courtesy of Seed Savers Exchange. Seeds or transplants of cool season veggies can be planted when the temperatures are at least 40 degrees, which is March and April in Virginia.  There are two types of cool season veggies. Hardy types can withstand a heavy frost and  temperatures as  low as 40 degrees so they can be planted two to three weeks before the average last frost. In Northern Virginia, the average last frost date is between April 10 and 21 so I arbitrarily pick April 15 to be able to remember. That means that I can either directly sow seed into the ground the weekend of March 25 (because I work during the week) or (having started the seeds indoors) I can plant the small plants into the ground. Semi-hardy plants can withstand a light frost and prefer slightly warmer temperatures toward 50 degrees so they have to be planted later, two weeks before average last frost date which would be the weekend of April 1. If a severe temperature drop would to occur, I would protect the plants by covering them with empty 2-liter plastic soda bottles that had bottoms cut off.

Winter is Witch Hazel Viewing Time in the Washington DC Metropolitan Area

Early Bird

Early Bird

One of my favorite winter bloomers is witch hazel, a small shrub like tree.  The flowers themselves are small, only a few inches big, but their unique shape and ability to cover dark, bare stems with flashes of color add quite a bit of excitement in winter gardens. The flowers are really clusters of four petals shaped like thin ribbons emanating from a dark, leathery base called a calyx. Depending on the cultivar, these inch to two inch long ribbons are translucent yellow or mustard yellow, red/orange or brown/orange, or scarlet red or rust red. On warm winter days, the ribbons unfurl but as temperatures drop, the ribbons curl back as a protective mechanism against the cold.

Gingerbread

Witch hazels are deciduous, about 15 to 18 feet tall and wide, with wavy-edged, hazel-like leaves. In the fall, the leaves turn a striking yellow, sometimes with orange or red tinges, before dropping to reveal an open vase structure.

There are many Hamamelis species but the more common ones are: Hamamelis japonica (Japanese witch hazel); H. mollis (Chinese witch hazel); H. vernalis (Ozark witch hazel); and H. virginiana (common or Virginia witch hazel). The first three are hardy to zone 4 or 5 while the last is hardy to zone 3. Common witch hazel is known for its use as an astringent in cosmetics. Hamamelis x intermedia is a cross between H. japonica and H. mollis – many cultivars have been bred from this to extend the flower color range as well as fall color of leaves.

Amethyst

Amethyst

Witch hazels like well-drained but evenly moist soil. They are forest understory plants, small enough for suburban properties but possibly requiring shade from the summer sun unless one can guarantee against drought. Usually they are not troubled by pests or diseases.

Witch hazels plants are easy to find and purchase at local nurseries in the spring but now is the time to view them in gardens in order to select your favorite flower color.  In Alexandria, Virginia, Green Spring Gardens has more than 200 Hamamelis plants. Green Spring Gardens’ witch hazel collection became an official Plant Collections Network (PCN) collection in 2006. PCN, a part of the American Public Gardens Association, is a network of botanical gardens and arboreta that coordinate preservation of germplasm. Member gardens make the germplasm available for studies, evaluation, breeding, and research. While Green Spring Gardens has the most extensive collection in the Washington DC area, you also can see them in bloom in other public gardens such as Brookside Gardens in Wheaton, Maryland, and the U.S. National Arboretum in Washington DC. Check out these perfect plants for the winter garden today so you can add few to your own garden this summer.
