We encourage you to subscribe to Washington Gardener Magazine as well for indepth articles, inspirational photos, and great garden resources for the Washington DC area gardener.

Reader Contest

For our June 2010 Washington Gardener Reader Contest, Washington Gardener is giving away 5 sets of passes to the Brookside Gardens Wings of Fancy live butterfly exhibit (each set has two passes and is a $12 value). Running daily through mid-September, from 10:00AM to 4:00PM, Brookside Gardens South Conservatory will feature live butterflies. Come witness the butterfly life cycle as tiny eggs hatch into crawling, chewing caterpillars, which then encase themselves in jewel-like chrysalides and emerge as sipping, flying adult butterflies. Learn about the best annual and tropical plants, and hardy shrubs that are used as nectar sources to attract butterflies to your own garden. To enter to win one of the 5 pairs of passes, send an email with “Wings” in the subject line to WashingtonGardener@rcn.com by 5:00pm on Thursday, June 30. In the body of the email please include your full name, email, mailing address, and your favorite pollinator-attracting plant. The pass winners will be announced and notified by July 2. Some of the entry responses may be used in future online or print articles.

Here is our comprehensive garden task list for gardens in the greater DC metro region for June 16-July 15. Your additions to this list are most welcome: If you started seeds last month, thin them and start the hardening off process. • Water newly planted trees and shrubs weekly or as needed. • Contact a certified arborist to have your trees’ health inspected. • Check on your container plants daily and keep them well watered. • Watch for insect and disease problems throughout your garden. • Mow in the early evening and cut off no more than one-third of the grass height at one time. Leave grass clippings on the ground to provide nutrients. • Add barley straw (in a bale or ball) to your pond to improve water clarity. • Take cuttings from azaleas and roses to start new plants. • Harvest herbs to use in salads and summer dishes. • Try a few new tropical plants on your patio. • Shape your evergreens and hedges. • Look for slug trails in the early morning and put out slug bait as needed. • Tie-up climbing roses and other wandering vines. • Fill in bare spots in the garden with annuals. • Deadhead spent flowers to encourage reblooming. • Prune flowering shrubs as their flowers fade. Last chance to do so for fall blooming camellias. • Spray roses with Neem oil every two weeks. • Start a sunflower patch with help from a few kids. • Harvest strawberry beds daily. • Cut a few flowers to enjoy at your workplace. • This is the perfect time to apply grub control. • Change the water in your birdbath daily and throw a mosquito dunk (or bits) into any standing water. • Put in supports for tomatoes and tall-blooming plants such as dahlias. • Order spring flowering bulbs to arrive for planting this fall. • Take photos and update your garden journal. • Inspect your garden hose for leaks and tighten all connections. • Weed. • Sow beets, beans, cucumbers, pumpkins, and squash for fall harvest. • Prune boxwoods. • Sharpen your lawnmower blade. • Avoid pesticides or any chemicals near your water garden. • Make hummingbird food by boiling two cups sugar in four cups water. • Turn your compost pile. • Clean up fallen fruit and berries. • Cover berry bushes and fruit trees with bird netting. • Dig up garlic when the tops turn brown. Let dry in the sun then braid and store. • Fertilize your azaleas and rhododendrons and monitor them closely for any lacebug damage. • Sow heat-tolerant greens like Swiss Chard and mustard greens in part-shade. • As the heat and humidity move in, take it easy by working in the morning or early evening to avoid intense sun and humidity. Leave the big projects for this fall. For now concentrate on maintaining the beds you’ve already established and nurturing your new plantings. • Have a wonderful 2011 growing season!

Washington Gardener Magazine is hosting an emPower HAPPY HOUR at Tabaq Bistro. Each month, emPower holds a Happy Hour event in support of a different non-profit organization in the Washington DC Metropolitan Area. The July Non-Profit emPower HAPPY HOUR Recipient: Washington Youth Garden. The Washington Youth Garden’s Mission: Using the garden cycle as a tool, the mission of the Washington Youth Garden at the U.S. National Arboretum (WYG) is to inspire children and families to engage in self-discovery, explore relationships with food and the natural world, and contribute to the health and well-being of their communities. The primary goals of our programs are to: a) educate youth and families about the relationship between food, its origins, nutrition, and health; b) connect children (and adults) to the natural world as a place of wonder, exploration and resource for their personal growth; c) develop interpersonal skills, awareness of civic responsibility, and land stewardship; and d) expand interest and public awareness of urban gardening and gardening with children. Attendees can give in two ways: • By drinking (10 percent of the beverage proceeds will go to the non-profit) • By bringing non-monetary donations (depending on the needs of the organization) Non-monetary Donations: ~ Cookbooks (gently used) ~ Garden Gloves ~ Trowels ~ Pruners ~ Spices (sealed) ~ Olive Oil (sealed) ~ Honey (sealed) ~ Vinegar (sealed) Date: THURSDAY July 7, 2011 Time: 5:30 PM - 8:30 PM Place: TABAQ Bistro is located at 1336 U St NW, Washington, DC -- a few blocks from the U St-Cardozo metro stop.

Making YOur Garden into a Hummingbird Habitat When I wanted to talk “hummingbird gardens” I went straight to the expert, Bill Hilton Jr., Executive Director of the Hilton Pond Center in York, SC, and the force of nature behind Operation RubyThroat: The Hummingbird Project. The first thing Bill, a science educator and nature writer, straightened me out on was that hummingbird “habitat” was a more appropriate goal. While a garden full of the hummingbird’s favorite nectar plants would be terrific, Bill urges home gardeners to also provide the thumb-sized birds with shrubs for protection from predators, water features that help attract small insects hummingbirds need for fats and proteins, and trees to nest in. In our Mid-Atlantic area, the earliest hummingbirds we’d see would be the first week of April. So Bill advises gardeners to put up one feeder by April 1. “No need to have it full,” says Bill. “Just a quarter to half full is fine at that point. Then have two or three up later on.” The height of ruby-throated hummingbird season for us is in late summer for us -- mid-August to early September. We see the last of them usually by October 1. Some local birders and gardeners have noted fewer hummingbirds in their gardens in the last few years. “Don’t panic,” soothes Bill. “It’s just a low cycle year and we really won’t know till the end of migration whether the numbers are truly down or not. It was a slow start this year, but now my counts are up to average. One reason could be the cool spring we had across the Southeast and a late frost that may have caused early eggs loss. On the other hand, this trumpet creeper blooming year is the best I’ve ever seen and that is the single most important nectar source for them so they should benefit from that.”

On Bill’s web site, www.rubythroat.org, he lists the Top 10 Native Hummingbird Plants. Trumpet creeper (Campsis radicans) tops the list. Followed closely by Beebalm (Monarda didyma), Trumpet Honeysuckle (Lonicera sempervirens), Cardinal Flower (Lobelia cardinalis) and Spotted Jewelweed (Impatiens capensis). Hummingbirds are particularly drawn to the red-orange color range that contrasts most with green. “It is easiest to see against the background of nature,” notes Bill. “And red-orange flowering plants carry the heavy nectar loads that require hummingbird pollination. Plant natives when possible, the hummingbirds evolved with them.” I asked Bill what we, as home gardeners, could avoid doing while trying to attract hummingbirds to our yards. “No pesticides!” Bill exclaimed. “They kill the small insects that hummingbirds need for protein, vitamins, and minerals.” He continued, “If you have feeders, don’t let the sugar water go bad. Change it twice a week in hot weather, if they don’t drain it. There is no need to buy commercially mixed sugar water. Make your own and avoid the artificial red dye. We are not for sure that the chemical dye is harmful, but it certainly has no benefit and most all feeders have red on them in any case, so it is not needed to attract the birds.” If you are interested in interacting up close with hummingbirds, Bill hosts an annual trip to Costa Rica in late winter. Each year they band and observe hundreds of hummingbirds to track and find where they migrate to and from. To find out all about hummingbirds, visit www.rubythroat.org.

Magazine Excerpt: Dumbarton Oaks by Cheval Force Opp

If you visit only one garden in the Capital Region, make it Dumbarton Oaks. It delights with every visit in every season. Beatrix Farrand and Mildred Bliss transformed the rambling farm perched on Georgetown’s highest point into one of the great 20th-century gardens, and much of the original garden has been preserved. Patrick Taylor in The Oxford Companion to the Garden states what other garden historians confirm: “Dumbarton Oaks is the only major garden on the east coast, other than the Rockefeller Eyrie Garden on Mount Desert Island in Maine, to retain the character and details of Beatrix Farrand’s design.” The mansion built in 1800 had many owners, the most famous of whom was Vice President John C. Calhoun (elected in 1824 with President John Quincy Adams). Diplomat Robert Woods Bliss and his wife, Mildred Barnes Bliss, purchased it in 1920 for their Washington residence. The couple, part of the Gilded Age rich and famous, spent 13 years abroad before finally returning to America to live at Dumbarton. All the while, they corresponded with Farrand, collaborating on the house renovation, refining the terraced gardens, and shipped over garden adornments. It’s hard to believe, but the couple only lived at Dumbarton Oaks from 1933-1940. Lucky for us, in 1940, they donated their collections, together with the house and its upper 16 acres, to create the Dumbarton Oaks Research Library and Collection, managed by the trustees of Harvard University. The institution’s focus is on Byzantine and Pre-Columbian studies, as well as Garden and Landscape Histories. The Garden and Landscape Studies collection began with the personal library of Mrs. Bliss. Holdings now include 27,000 books and pamphlets covering the history of gardens and landscape design. The largest emphasis has been on gardens of the Western world, especially the United States and Europe, but collecting in recent years has included gardens of the Islamic world, China, Japan, and Australia. Many of the volumes are located in the Rare Book Collection. Mildred Bliss continued to oversee the garden, a favorite obsession, until her death in 1969. Beatrix Farrand’s (1872-1959) collaboration with Bliss at Dumbarton Oaks started in 1922 and continued for 30 years. A landscape trailblazer, Farrand is still studied for her exceptional designs. Farrand, self-described as “Landscape Gardener,” ... Want to learn more about Dumbarton Oaks? Read the rest of this DayTrip column in the Spring 2011 issue of Washington Gardener Magazine.
