An estimated 4000 susceptible elms grow in Seattle, and the disease has the potential to destroy 18% of the city’s large tree population. American elms are the most susceptible, although all elm species are vulnerable. We hope that by attacking the problem early, widespread damage can be prevented. History: DED is caused by a fungus that was introduced into Europe in 1919 from Asia and was first described by a Dutch biologist, thus the name Dutch Elm Disease. After entering the United States in the 1920’s, the disease rapidly spread throughout the native and urban elm populations throughout North America. A more aggressive fungus has since replaced the original strain and is responsible for the disease damage that is seen today. Symptoms: Symptoms of DED include small, sparse leaves in spring, usually at the top of the tree, followed by a sudden wilting of leaves in early summer. Leaves curl and turn brown and in late summer may fall prematurely. Infected branches often show a brown stain on the wood, seen by peeling back the bark. At first, individual branches may be affected although symptoms may spread rapidly throughout the tree. Young, vigorously growing trees may be killed in several weeks whereas larger, slower growing trees can take one to two years. Source of disease: Elm bark beetles are the vector for disease transmission. The beetles lay eggs underneath the bark of a stressed, dead or dying tree. When the mature beetles emerge, they carry with them the spores of the DED fungus. As the beetles move to other elms to feed or spend the winter, infection is spread to healthy trees. Infection can also spread through the root systems of adjacent trees if the roots are growing together. ( continued on page 5) CUH and the PNW Chapter of the International Society of Arboriculture are sponsoring a free public forum on diagnosis and control of Dutch Elm Disease on Friday February 1 5 at 7 p.m. Visit the CUH website at www.urbanhort.org or call 206-68S-8033 for more information. /orURBAN HORTICULTURE CENTER FOR URBAN HORTICULTURE WINTER 2002 CUH Healthy Garden Symposium at the Northwest Flower and Garden Show Friday, February 8, 9:45 a.m This special series of lectures on healthy gardening features faculty, staff, students, and alumni of CUH, all experts in their fields. gardening in this place.

When Pruning Hurts Plants LINDA CHALKER-SCOTT, PhD, ASSOCIATE PROFESSOR, CUH Gardeners are often advised to prune back the crown of transplanted trees and shrubs by as much as 50% to reduce transpiration and compensate for lost root systems. Internet web sites, even the usually reliable “.edu” sites, continue to spread this myth. Research performed under landscape conditions shows that pruning when transplanting is not necessarily beneficial, and may even harm the tree. There may be short-term benefits in balancing the root and shoot mass, but the long-term effects are generally negative. When growing tips are removed from most plants, the plant responds by putting its resources into shoot growth at the expense of root growth. So although gardeners may see the top part growing, they are unaware that root growth is inhibited. In contrast, plants left intact after transplanting may appear to be dormant but are actually putting resources into root growth. Shoot growth resumes after roots are established. Top-pruning also removes a significant amount of biomass which decreases photosynthesis. So the plants are hit with a “double whammy”: reduced photosynthesis and growth of shoots instead of roots. It’s no surprise that roots have a hard time growing after the top is pruned. Research assistance for this article was provided by Greg Hostetler, UW student.

CARING FOR NEWLY TRANSPLANTED TREES AND SHRUBS: • Don’t top-prune landscape plants when transplanting. Water well afterwards. • Only prune broken, dead or diseased branches from newly transplanted trees or shrubs. • If pruning is warranted, use thinning rather than heading cuts. Assessing Washington’s Urban Forests KATHY WOLF, RESEARCH ASSISTANT PROFESSOR, CUH CUH graduate students and faculty are assessing the urban forest in Washington. This project will help streamline urban forestry across the state. Currently, individuals who plant, main- tain and protect trees work independently and “reinvent the wheel.” The results should help to create a unified approach that will impact policy decisions pertaining to resource alloca- tion and tree ordinances. The study is being performed in three phases: l)Assessing tree inventory databases, 2)Reviewing management practices used in Washington cities and towns, and 3)Assessing the urban forestry policies of Washington municipalities. Graduate student Robeit Codetta started phase one by collecting data from 27 Wash- ington municipalities about tree inventory procedures. Tree inventory systems are city-wide databases, used to monitor the health and condition of urban trees. His results will help communities to more efficiently set up and use the inventories. Phase two is being carried out by graduate student Noel Studer who is assessing the management practices being used by Washington’s cities and towns, including professional staffing, budgets, work schedules and tree care practices. Phase three will involve collecting and analyzing the policy and ordinances of Washington municipalities regarding trees and forests. Faculty members Al Wagar, John Wott and Kathy Wolf are participating in the study which is sponsored by the US Forest Service through the Department of Natural Resource’s “Urban and Community Forestry Program.” CENTER FOR URBAN HORTICULTURE WINTER 2002 News from CUH and WPA a. i Q Z < X D U z 0 cc.

The Miller Library has been closed since May 21 as staff has worked in other libraries on campus and, along with volunteers, cleaned, re-labelled and re- jacketed library books. Now the collection has been freeze-dried, treated with ozone and cleaned. A majority of the books and files are ready again to fill library shelves. The Isaacson Hall classroom, just off the CUH courtyard, will house the reading room with a selection of journals, reference books, and lending books. Reference help will be available, the Plant Answer Line will operate, and two computer terminals will be available for public use. The downstairs of Isaacson Hall will house part of the rest of the collection, work space for library staff, and the Hyde Herbarium. Due to limited space, at least half the library’s book collection will continue to be housed at Sandpoint until the new Merrill Hall is built. Library staff will take requests and pick books up at Sandpoint twice each week. The old and rare books remain in Allen Library on the UW upper campus until we again have a safe and secure facility for them at CUH. Thanks to the Northwest Horticultural Society for sharing office space with library staff. Their generosity has allowed a base of operations that has helped get the library going again. Starting December 10, the library will be open its regular, pre-fire schedule: 9 a.m. to 5 p.m. Tuesdays through Fridays, 9 a.m. to 8 p.m. on Mondays, and 9 a.m. to 3 pm. on Saturdays. We appreciate your patience and we look forward to getting back in business again. Please bring in all those questions you’ve been saving up. CUH Facility News Meeting space is tighter than normal due to the library’s move to Isaacson Classroom. Anyone requesting rental space should place their reservations as early as possible. Facilities managers Ray Larson and Becky Johnson continue to serve the horticultural and local community and will try to accommodate eveiyone who submits a request. Graduate students Steve Van Hoven, Sean Dugan and Robert Corletta have been hired part time to assist with facilities management. You may bump into one of these fellows at either the reception desk or in the classrooms, as they are setting up or taking down equipment. Five trailers are now located on CUH grounds. While Merrill Hall is rebuilt, these are providing office space for staff and faculty, student desk and computer space, as well as laboratory facilities. Ensuring that trailers have computer hook-ups, telephone and electrical connections and heating/ventilation systems has been no small task, and many individuals are to be commended for their help. Next time you visit CUH, be sure to admire the containers placed around McVay Courtyard and the Soest Garden. The containers were bought with a generous donation by Steve Burgess, UW professor and neighbor. Valerie Easton and Ray Larson recently redesigned the plantings for winter interest. Eagle Scout Completes Project Eric Bowley completed an Eagle Scout Project in the Washington Park Arboretum. Eric chose to improve the public image of the Puget Sound Beekeepers Exhibit, housed behind the greenhouses. The entire area has been fenced with fence posts and yellow rope. A series of signs will be installed on the posts so that visitors can learn more about bees. They will also be used as a teaching tool for the Saplings School program. The area will also be marked with two entrance marquees. The bees are the source of the famous Arboretum honey which is sold in the gift shop. Graduate Students Earn Degrees Perry Gayaldo, PhD. Perry's research was concerned with the restoration of coastal marine habitats, eelgrass restoration in particular. He characterized the marine sediments and shoreline conditions where eelgrass grows and correlated its growth to these conditions. He also investigated how oxygen availability is related to growth of eelgrass. Finally, Perry performed a case study for the Port of Anacortes. He increased eelgrass habitat by removing submarine debris and sections of dock, installing reflective panels underneath a dock and selectively transplanting eelgrass. Stephen Brueggerhoff, M.F.R. Steve surveyed visitors to the UW Medicinal Garden. His survey showed that visitors to the garden use it primarily for its restorative or stress relief aspects. They also use it for an informal learning, as opposed to a formal teaching, experience. Emily Griswold, M.S. Emily researched the origin and development of ecogeographic displays, or gardens that mimic natural plant communities. She found that the origin of this display concept was closely tied to the emergence of the science of plant ecology and to the development of dioramas in natural history museums. Robert Corletta, M.F.R. Robert collected data regarding tree inventory procedures from Washington state municipalities. His results will be used to create a “toolbox” for communities to develop or improve their tree inventories. Michelle Connor, M.S. Michelle’s research focused on stands of our native spiraea, Spiraea douglasii, in wetlands of the lowland Puget Sound region. She examined how the spiraea is able to outcompete other plants, what conditions favors its spread, and how it should be managed in natural systems and restoration sites. Dutch Elm Disease (continued from page 1) Prevention and Control: To keep a healthy elm from becoming susceptible to DED, maintain the tree in prime condition through proper tree care. This includes pruning all dead wood during the dormant season (between October 1 and March 30), along with regular watering and mulching. Healthy trees can be injected during the summer with the fungicide ‘Arbotect’. Although injections are moderately expensive and must be repeated every few years, they can be effective even if the tree exhibits early symptoms. If a tree on your property is diagnosed with DED, it should be removed within 2 weeks. Pruning out diseased areas will have no effect unless detected in the very early stages. Be sure to remove all dead and diseased elm trees and firewood. Only store the tree for firewood if the bark has been removed or beetles will be provided with habitat for reproducing. Further information and diagnosis: Assistance is available to property owners who require information about identifying elms, DED symptoms, and prevention and management methods. For trees within the City of Seattle, call the City Arborist’s Office at 206-684-7649 or 206-615-0957. Outside of Seattle, call a private arborist or a local municipal tree expert. If you need a company to spray, prune or inject your elm trees, look in the phone book under Tree Service. Ensure that the company you select employs certified and insured arborists and tree pruners. Companies which spray or inject trees must hold a pesticide applicator’s license.

A Great Reason to Reduce Pesticide Use Traces of garden pesticides have been found in the urine of a number of Seattle-area preschool kids. All but one of the 110 children tested had minute amounts in their samples. Researchers noted that children whose parents used pesticides in their gardens had a significantly higher concentration. The study was con- ducted in 1998 by University of Washington researchers and published in the March edition of Environmental Health Perspectives.

CENTER /orURBAN HORTICULTURE REGISTRATION FORM UNIVERSITY OF WASHINGTON CENTER FOR URBAN HORTICULTURE 6 - director’s notes We now have $4,103,000 and an architectural firm, The Miller/Hull Partnership, to help us rebuild Merrill Hall. We are excited about the pre-design phase of the project with many hours devoted to every detail of the “new” building. Will a new building be more inviting to the public? How will the outreach and programmatic elements of the Center work together? Can the building be a showcase for sustainable design? Will the building integrate with the site in exciting ways? Wrestling with these issues has been challenging but enjoyable these last few months. At the same time, we have also begun to talk about implementing the newly- approved master plan for the Arboretum, conduct the business of the present, and still recover from the May 21 fire. In all of these activities, the University has been extraordinarily supportive. We now have five trailers surrounding Douglas. The Elisabeth Miller Library and Hyde Herbarium are scheduled to open in termporary quarters before the holidays. However, layered on all of these activities is the September 1 1 tragedy, the condition of the state’s economy, and the very strong likelihood of significant budget cuts at the University of Washington. Our dreams about the new Merrill Hall and your support have made the valleys less deep and have sustained the high points. Thank you!
