With West Nile Virus (WNV) now in our state, there is reason for caution but not panic. Despite heavy news coverage, WNV has barely arrived. Rash action with excessive and unncecessary spraying can actually increase mosquito problems by removing the checks and balances that keep mosquito populations low. Here are some common sense tips to keep in mind this summer: Where WNV outbreaks have occurred, there is evidence that many people have contracted it without knowing they were sick; or they experienced only mild flu-like symptoms. As with the flu and other common diseases, the most susceptible people to WNV are those with compromised immune systems, the elderly and very young. Susceptible people should take special precautions against mosquitoes. Check with your physician if you have flu-like symptoms with a rash. Beware that WNV may become a popular and “easy-out” diagnosis; physicians should request a lab test to confirm the disease. The virus is not spread by casual contact and humans are not a preferred host. In the Home and Garden Mosquitoes breed in calm waters. Remove or manage water sources by cleaning gutters and drains, removing old tires, and turning over buckets, pots, toys, and other containers. Fix leaky faucets and sprinklers, and remove puddles. Replace the water in bird baths, fountains or wading pools every four days if larvae are present. Stock ponds with fish to consume mosquitoes; check with pond specialists on the best ways to protect the fish from raccoons. Turn ponds or low spots into bog gardens (no standing water) with appropriate plants.

On Sunday May 4 from 5 p.m. to 8 p.m. the Northwest Horticultural Society hosts its eighth annual auction and garden party to benefit the Miller Library. Gardeners will gather to enjoy this fine party at CUH while helping raise funds to furnish the new and improved Elisabeth C. Miller Horticultural Library. Cost is $65 (benefactor donation $150). NHS members automatically receive invitations. If you are not a member and would like to attend, call the NHS office at 206-527-1794. Learn to photograph gardens by learning how to see in the garden. Allan Mandell is an award-winning professional garden photographer whose work is published internationally in leading garden magazines and books. His books include Artists in their Gardens and Naturalistic Gardening. He will teach students to work toward a new understanding of what it means to practice photography in this 3-part class that includes a lecture, photo shoot at the Bellevue Botanic Garden, and follow-up potluck/critique session. See additional information on page 9 of this newsletter. The Rare Plant Care Program at the Center for Urban Horticulture is sponsoring a Celebrating Wildflowers event to promote appreciation of Washington State’s native plants. There will be lots of activities for kids (wildflower coloring, pollinator game, microscopes to look at flower parts, and petting moss). The U.S. Forest Service, Native Plant Society, and other program sponsors will have information available on how you can help protect our native plants. Look for the fun near the Butterflies and Blooms Exhibit at Woodland Park Zoo. West Nile Virus Tips (continued from page 1) Join with your friends and neighbors to help the elderly and others who are unable to remove mosquito breeding sites themselves. Landscape professionals can be especially helpful in spotting mosquito breeding areas and advising customers. Place or repair screens on all doors and windows. Do not spray inside buildings to kill mosquitoes. This provides relief only until the next mosquito flies in the door. Protect Yourself and Your Pets People vary in their attractiveness to mosquitoes and mosquitoes vary in the time of day, or season, that they bite. Most are active at dusk and dawn but some are day fliers. Mosquitoes have favorite areas you can avoid, and they are less active when it is windy and cold. Most human infections occur in late summer during hot weather. If you are among the “chosen”, wear long-sleeved shirts and long pants made of tightly woven fabric, and hats with mosquito netting especially near woods or ponds. Use a mosquito repellent formulated with DEET or Eucalyptus Oils labelled as repellants. Apply lower concentrations of DEET (10 to 35%) lightly to any exposed skin only if needed. Use higher concentrations ONLY on clothing, netting, or tents. READ, and FOLLOW THE LABEL (especially the “fabrics-to-avoid” info). See health websites for more detail, particularly for children under the age of 2. For pet birds, dogs, cats and horses, consult with your veterinarian or the web. Do not use repellents unless advised by a vet. Animals can ingest the repellent when they are grooming. Birds and horses are especially susceptible to WNV, but not most dogs and cats.

Developed by Douglas Jackson & Associates, the bed was designed to represent a typical Olmsted-designed park. “Signature plants” used by the Olmsteds include cotoneasters, viburnums, rhododendrons, spireas, dogwoods, and several northwest natives, including salal and evergreen huckleberry. These and other plants were selected to demonstrate the casual feel, the layering effects, and the unusual combinations of color (in bark, foliage and bloom), leaf shape and texture that the Olmsteds were famous for. The bed includes a greater variety of plants than would typically have been used in that small a space. Plant lists for the Signature Bed are available at the Graham Visitors Center. Stop by and pick up some Olmsted-inspired ideas for your own garden. Visit the FSOP website for updated information on Olmsted events. It is at http://www.cityofseattle.net/ friendsofolmstedparks! .

Spring Garden Care Advice from the Master Gardeners Master Gardeners report that many of the questions asked in the fall have their prevention or remedy in early spring. Peg Pearson, Master Gardener, offers tips for planting, pruning, lawn care and other seasonal topics with fresh spring eyes: Planting and Dividing Transplanting and dividing before new growth emerges contributes to better odds of success. This mild year, many plants are ahead of schedule and the window of opportunity has passed. Fall actually is the preferred time for planting most trees and shrubs here. As with newly potted or bare-root plants, planting and transplanting should not be attempted when soils are saturated. Wait until you cannot make a solid “mud-ball” with your soil before doing serious digging or tromping in your spring garden. Hostas may be divided just as the First leaf tips poke out of the ground. Dig up the whole clump, rinse the roots free of soil, and look where to cut so that viable roots will support each unit of new growth. Use a sharp, clean knife. This technique also works well with heucheras and hardy geraniums. Pruning Foliage and seed heads left on ornamental grasses, ferns, sedums, fennel, lavender and oregano need cutting back before new growth makes the chore more tedious. Rhododendrons and camellias may be pruned to reshape and control size in the two weeks after flowering to ensure flowering next spring. In general, spring-flowering plants may be pruned shortly after bloom. Removing at the ground a third or a fifth of older stems of shrubs like red- twig dogwood produces the new red stems that we admire in winter. Butterfly bush (Buddleia) and smoke tree ( Cotinus) may be pruned down to a height of 18" to 36" before growth starts. You will end up with a bushier, less lanky form. ratio fertilizers. Aerate and top dress with 'U to V2 inch of compost, then overseed damaged areas in May. Use mulching mowers to recycle up to 23% of your lawn’s nutritional needs over the growing season. If chemicals are required, only Diazinon remains registered for home use. However, it must be applied between April 1 to 15 to avoid injuring nesting birds and won’t be sold after December 31 of this year. Temperature and Water Even with the recent mild winter, temperatures could still dip below freezing. The average last frost date at CUH is February 21 while colder pockets and higher elevations may have a cold snap after Mother’s Day. Soil temperature is important for warm weather plants such as tomatoes and basil. Although spring plant sales sell them in April, do not plant before Memorial Day, since a soil temperature of 50 to 55 degrees F is required. Our prolonged dry spell since last July will surely impact our gardens and water bills this year. Western red cedars and pines shed more last fall. How trees and shrubs leaf out this spring may give clues of drought damage to roots and indicate a need to mulch with compost or wood chips to improve water holding capacity and reduce evaporation. The Master Gardener hotline is available to answer gardening questions. Phone 206-296-3440 Monday to Friday I 0 a.m. to 4 p.m. 7 Plant Selection Don’t forget that plants have preferences in location, soil, light, and water when shopping at spring plant sales. Planting the right plant with the right companions in the proper place can create sections of your garden requiring less water and mainte- nance. Many native plants offer texture, structure, and wildlife habitat while saving resources as well as your time. Lawn Care Crane fly monitoring in February and March is the key step. Remove random 6" squares of turf and look for the larvae near the top of the soil layer. In lawns struggling to thrive on 1" of topsoil, damage may occur with very few numbers, whereas lawns with a healthy soil base (6" to 12" of sandy loam) may take more than 40 larvae per square foot to show damage. Cultural controls are preferred.

CENTER for URBAN HORTICULTURE REGISTRATION FORM UNIVERSITY OF WASHINGTON CENTER FOR URBAN HORTICULTURE director’s notes This spring brings excitement as Merrill Hall nears ground breaking. Fundraising continues, with the Northwest Horticultural Society holding its eighth annual auction and garden party, “Blueprint for the Future”, on Sunday May 4 to help furnish the Miller Library. Over 400 tiles have been sold to support the Merrill Hall Commons, bringing in $1 10,000; however, more than $170,000 is still needed to fully develop this central space, so our fundraising work continues. The UW will apply for a building permit by the end of March, hoping to begin construction in July. The Miller Seed Vault was recently completed this winter inside the Douglas Conservatory with a grant from the Miller Foundation. The seed vaults main purpose is to provide long-term seed storage of Washington’s rare plants as well as seeds of horticultural value. We are thankful for the support of all who are helping us rebuild and grow.
