Spotlight Special New Berry Shrubs

At MANTS 2012 this past January, Fall Creek Farm & Nursery, Inc. unveiled their new BrazelBerries™ Collection of small ornamental fruit shrubs that will change the way gardeners and retailers think about berry bushes. “BrazelBerries is an exciting new venture for us — bringing a collection of new varieties targeted specifically to the home garden market,” says Amelie Brazelton Aust, New Products Manager and a second-generation owner of Fall Creek. “With the soaring consumer demand for blueberries and the trend towards edible landscapes and sustainability, we decided the time was right to introduce a collection of berry bushes for the home gardener.” Through their private breeding program and breeding partnerships, the Brazeltons and their team have spent the past 20 years working to develop blueberries and other small fruits specifically for the home gardener. “Our family’s goal was to develop new varieties that met our three key breeding criteria: simple, beautiful and delicious,” say Aust. “First and foremost these new berry plants must be beautiful, ornamental shrubs. Then they must be simple to grow, and produce delicious, abundant fruit.” Historically, home garden berry bushes lacked ornamental appeal. “They were bred for commercial production so they were bushy, not very pretty and most often relegated to the garden,” she explains. “BrazelBerries are gorgeous plants that bring beauty and healthful, delicious fruit to the patio or ornamental landscape.” Initial quantities will be available in 2013 to independent garden centers exclusively through an established network of wholesale growers.

April Garden To-Do List

Here is our comprehensive garden task list for gardens in the greater DC metro region for April 16-May 15. Your additions to this list are most welcome: If you started seeds last month, thin them and start the hardening off process. • Start some more seeds -- especially try flowering annuals like impatiens, marigolds, nasturtium, and petunias. •Do not set out seedlings or tender annuals until after Mother’s Day (traditional last frost-free date for our entire area). • Water shrubs and trees deeply during any dry spells. • Prune winter damage on evergreens. • Make compost tea and use on seedlings. • Turn your compost pile • Sharpen tools. • Prune flowering shrubs, such as forsythia, lilacs, and azaleas, when they finish blooming. • Repot and fertilize houseplants. • Set aside a few hours each weekend for attending garden shows and tours. • Weed by hand to avoid disturbing newly forming roots. • Soil preparation -- add lime, compost, etc. as needed. • Walk your garden -- look for early signs of fungal disease. • Divide perennials and herbs. Pot up extras to give away at plant swaps. • Fertilize new growth. • Plant and prune roses. • Transplants small trees and shrubs. • Buy or check on your stored summer bulbs (such as dahlias and caladiums). Pot them and start to water, if you want to give them an early start on the season. • Build a raised bed for vegetables. Add lots of manure and compost. • Buy an indoor plant to liven up your office space. Try an orchid or African violet. • Start/keep fertilizing your indoor plants. • Cut back and clear out the last of your perennial beds and ornamental grasses. • Mulch beds with a light hand. • Feed birds and provide nesting materials (try dryer lint) as well as houses for the start of their family season. • Sow beans and corn directly outdoors. • Start carrots, turnips, and parsnips in well-draining beds or in deep containers. • Keep cutworms off newly planted edible seedlings by surrounding them with a collar cut from a plastic bottle or cardboard tube. • Pick peas often to encourage the plants to produce more. • Ensure new seedlings do not dry out by installing a drip-irrigation system. • Start herbs from seed or cuttings. • Edge garden beds. • Remove Ivy, Pachysandra, and other vine-like groundcover from under shrubs. • Work in dry, not wet soil to avoid compacting the earth. • Hand pick cabbage worms from broccoli and other cabbage family plants. • Put row covers over vulnerable crops — remove cover to allow for pollinating once they set flowers. • Thin lettuce seedlings and plant more seeds in new rows. (You can eat the seedling greens you pull.) • Plant a tree for Arbor Day or Earth Day.

Propagate Plants from Softwood Cuttings By Kathy Jentz, Editor of Washington Gardener Magazine How does the concept of FREE PLANTS sound to you in these economically troubled times? You probably know about plant multiplication by dividing overgrown old ones or starting new ones from seed, but have you ever attempted propagation by softwood cuttings? It is one of the easiest garden tasks you’ll undertake as well as the most rewarding. In a short time, you’ll have plants to fill out your beds and more to pass on to your gardening friends. The best window in time for taking softwood cutting to create new shrubs and trees is mid-May to early June. You can try some earlier though and start now in planning which ones you’d like to propagate from your own garden as well as “shopping” in your friend’s gardens. (With their permission, of course!) Recommended shrubs and trees for softwood cutting propagation are boxwood, azalea, lilac, euonymus, forsythia, weigela, barberry, viburnum, fig, roses, crabapple, quince, gardenia, camellia, flowering cherry, and hydrangea. You can also do this on “woody” perennials including geraniums, fuschias, dianthus, and chrysanthemums. This azalea, pictured here from my garden, was created from a small softwood cutting four years ago and is about two feet high and wide this spring. You will be selecting this season’s growth from your woody plants. The new, green wood is best for this purpose. The plant material should be flexible though mature enough to snap when sharply bent.. Use a sharp, and sterilized pair of pruners or knife to take your cuttings. Consider what you are doing as “plant surgery” and use good hygiene standards. Before you start cutting, prepare the growing medium (sterile moist sand, vermiculite, or perlite) and your pots. You do not want the cuttings to dry out at all and you’ll want to work quickly. Be sure your container has a cover to reduce moisture loss. You can use a store-bought large seed-starting tray and dome. Alternatively, you can make your own out of recycled salad bar trays, just be sure to provide good drainage holes. Cut a three-to-four inch length from the growing tips of the plant. The cut should be made at a slight angle, just below a node. (A node is the point on a stem where a leaf emerges.) Next, keep the top few leaves, but prune away any flower buds and the lower leaves from the cutting. Dip the cut end into a rooting hormone such as Rootone® and bury it in the growing medium until at least one node is covered. (The nodes are where the new roots will emerge.) Water the rooting medium well. Then cover them. Place the potted and covered cuttings in a bright, warm spot -- though out of direct sun. Within a few weeks the cutting will start to form roots.. Give it a tug periodically to check. When it has formed a well developed root system, remove the cover and transplant the cutting into a container by itself. Newly rooted cuttings should not be transplanted directly into the landscape. Grow the plant to a larger size before you transplant it to a permanent location and that will increase its chances for survival. 

Magazine Excerpt: Green Roofs and Walls by Kathy Jentz

Green roofs have many benefits, including holding in stormwater run-off and filtering out pollutants. Green roofs cool and humidify the surrounding air, creating a microclimate in an urban heat island. They also keep building temperatures regulated, especially in the summer. A common concern about green roofs is that they may cause leaking problems. In actuality, green roofs have proven to be much stronger and more efficient than regular roofing materials at keeping water out. But, just in case, United Therapeutics has a back-up plan. “We have lots of leak detection systems – moisture sensors built into the ceilings,” explained Halpert. The building and green roof were completed just under two years ago. The green roof plantings were designed by renowned local landscape design firm Oehme, van Sweden and Associates and are maintained by Ruppert Nurseries. “We wanted to show that green roofs can support a lot more than just sedums, “ said Sheila A. Brady, Principal, VP, FASLA at Oehme, van Sweden and Associates in Washington, DC. Brady designed the green roof gardens to include many native perennials that are low-maintenance and offer multiple seasons of interest. There are two main types of green roofs — extensive and intensive. Extensive green roofs use a very shallow growing medium with plants that have shallow root systems. These roofs are the most popular for retrofits since they generally weigh less than 50 pounds per square foot, including all live (snow, plants, water) and dead (structural components) loads. Green walls date back to the Hanging Gardens of Babylon. There are a number of green wall systems you can buy commercially, from Woolly Pockets to grid vine supports....
