April Garden To-Do List

Spotlight Special Mulberry ‘Issai’ (Morus alba)

Rare and hard-to-find, Mulberry ‘Issai’ is a dwarf tree that performs admirably as a container plant. The fruit is larger than most dwarf mulberries, and the plant flowers and fruits most of the year in repeating cycles.

When grown as a container plant, its plump sweet fruit is easily picked and is also easily protected from birds with lightweight netting.

Mulberry ‘Issai’ is hardy as a garden plant in zones 5-9. When grown outdoors, it is deciduous. When grown inside in a container, it reaches 2-4 feet tall and will hold its leaves and continue to flower and fruit as long as the light level is high enough (a southern exposure is best.)

Maintain indoor temperatures above 35 When grow outside in sub freezing temperatures in containers the pot needs to be mulched to protect the roots from freezing and thawing.

Moderate to heavy feeder under warmth and high light. Feed with a balanced fertilizer at regular intervals through it active growing season. Don’t fertilize under low light and warm temperatures, which can be found in indoor growing conditions.

Pruning plants in late winter or early spring will allow the summer growth to produce fruit. Seasonal varieties should be pruned after fruiting is complete or in winter when the branches are thinned and headed back enough to maintain form as fruit buds developed on the previous season growth.

Allow the soil surface to become visually dry between waterings and then thoroughly saturate the soil. Try to avoid a severe wilt.

One plant in a 4-inch pot sells for $19.95 in Logee’s catalog based in Danielson, CT, a destination greenhouse for thousands of gardeners throughout the Eastern United States. To receive a free Spring 2013 catalog or place an order, call Logee’s at 1888-330-8038 or visit the website at www. logees.com.

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.

Impatiens Alternatives:

Downy Mildew Disease Drives Local Gardeners to Search for Inventive Solutions for Color in the Shade

by Kathy Jentz

You may have heard that a soil-borne disease, Impatiens Downy Mildew, hit the Eastern half of the U.S. last summer. Some had it worse than others. If you grew Impatiens walleriana and you were not impacted, count yourself lucky. For those hit by it, whole beds and containers of Impatiens seemed to collapse and lose all their flowers and foliage overnight.

It spreads when sporangia (sac-like structures filled with zoospores that are produced on the underside of infected leaves) are easily dislodged and spread short distances by water splash and longer distances by air currents (up to 100 miles).

Once a plant has been infected there is no cure. There are preventative fungicides that can be applied by licensed professionals while the plant material is being grown at grower greenhouses. These fungicides have proved affective preventing the disease for short periods of time. Unfortunately, at this time, there are no home sprays for the general public to use.

It is not known how many years the disease may live on in the soil, so good gardening practice is to dispose of the soil, if in containers, and the plants in bags. Please do not add them to your compost pile.

Most reputable garden centers and nurseries will not be carrying Impatiens this year in a cooperative effort to eradicate the disease. “Obviously, we are not carrying them. It is just too much of a risk to our customers’ gardens,” said Bobby Lewis of Meadows Farms Nurseries.

Note that the New Guinea Impatiens (Impatiens hawkeri) are not effected by this disease and are fine for your garden. They can take more sun than Impatiens walleriana and are a bit more expensive as they are tissue-propagated and not grown from seed. They come in more vibrant colors and variegated foliage as well.

Listed here are several choices for adding color to your shade gardens. Part-shade is defined as 3-6 hours of direct sunlight. Full-shade as 3 hours of direct sun or less. Perennials are plants that may die back over the winter, but come back each year. Annuals last for just one growing season.

Kathy is going to miss using Impatiens in her shade-filled back garden, but is looking forward to experimenting with different shade-loving varieties . She is the editor of Washington Gardener Magazine (www.WashingtonGardener.com) and a long-time DC area gardening enthusiast. Kathy can be reached at wgardenermag@aol.com and welcomes your gardening questions.

TOP AREA GARDENING EVENTS DC-Area Gardening Calendar ~ Upcoming Events ~ April 16 - May 15, 2013 • Wednesday, April 17, 7:30 - 9:00pm Ben Morrison and His Azaleas Talk This meeting is jointly sponsored by the Takoma Horticultural Club and Historic Takoma Inc. It will feature the ardent azalea aficionado William (Bill) Miller III, speaking on “Ben Morrison and his Azaleas.” The Glenn Dale azaleas, which are a feature of city parks and gardens in Takoma Park, were developed by the first director of the National Arboretum, Benjamin Y. Morrison.

Beginning in the late 1920s, he worked more than 25 years to achieve a group of winter-hardy azaleas with large, colorful flowers, suitable for the Washington, DC region. Eventually the program included 454 hybrids. They are probably the best known and most popular feature of the Arboretum today.

Morrison lived nearby on Piney Branch Road and shared his hybrids with many Takoma Park friends.

Held at the Historic Takoma, 7328 Carroll Ave, Takoma Park, MD. FREE and open to the public. Doors open at 7, talk starts at 7:30 p.m. Please bring a snack to share. As usual, the Club will provide beverages. Wear a recycled name tag and save a tree. More details at: www.takomahort.org.

Magazine Excerpt: A Dependable Duo of Native Azaleas

BY BARBARA L. BULLOCK Native plants are getting a lot of press these days, much of it through electronic media and internet sites. Many nurseries now specialize in native plants. A successful native plant design calls for a knowledge of plants native to your region, the growing conditions they require, and combining or layering plant types like trees, shrubs, and groundcovers to create a diverse habitat for insects, birds, and animals. This does not mean you have to give up beautiful flowers. One group of natives, the native azaleas, can and should be used more often as part of today’s landscapes. The North American native azaleas are curiously absent from the traditional gardening pallet but are among the most beautiful ornamental shrubs in the world. It might surprise you to learn that many native azaleas are not difficult to grow.

They’re deciduous, which may be the reason they are not more widely grown.

There are two azalea species that grow without the help of the gardener’s hands in Washington, DC area woodlands: the pinxter azalea, Rhododendron periclymenoides and the swamp azalea, Rhododendron viscosum. The pinxter azalea, sometimes called “wild honeysuckle”, is quite showy and has long stamens that extend past the perianth evoking the look of Japanese honeysuckle (Lonicera japonica). Its delicate flowers are white to pale pink but it’s not particularly fragrant. The swamp azalea is very fragrant with tiny white flower clusters appearing in late June. They are great plants for woodland gardens, but gardeners looking for azaleas with loads of bright spring flowers that are adaptable to a range of conditions might want to consider a couple of azaleas that are found in other parts of the eastern U.S. ...

Want to learn more about this two native azaleas? Read the rest of this Special Feature Story in the Spring 2013 issue of Washington Gardener Magazine now printing and mailing soon. See how to subscribe below to start with this issue.
