Cost: $25; pre-registration required
Instructors:

firm.

Bernie Hedeen, Partner, General manager, and Chief Designer of General & Marine
Construction Company.

Bernie Hedeen, who has many years of experience with slope repair and foundation
construction, will discuss slope components including soil structure. He will relate
glacial history to how it effects the management of these areas. Issues such as soil
types and their characteristics, soil friction and cohesion, soil reports, and landslide
types in the Northwest, and repair methods will be discussed. Pat Roome, who
specializes in slide prevention and remedial design, will discuss the role and
selection of plants for repair after slide damage and preventive measures on
potential slide areas. She will focus on how to select aesthetic plants that exhibit
the necessary properties for erosion protection, are adapted to the climate of the
slide, are pest and disease resistant, and require no water or maintenance. There
will be time for questions and discussion.

Root pathogens such as phytophthora have devastating effects on the landscape,
especially when infecting large, established trees. These diseases often appear to
have few if any controls or treatments. In fact, there are many techniques to
prevention and management of root pathogens, such as soil conditioning and
mycorrhizal injections. Continue on next page.

The latter half of the seminar will focus on examples of diagnosis and management
practices currently in use at the Washington Park Arboretum. Please join us to
discuss and explore these issues which are so prevalent in the Pacific Northwest
landscape.

Academic Education at CUH

Many of you are aware of the outreach education programs such as ProHort semi-
nars that the Center for Urban Horticulture produces each year. It is in fact part of
the Center’s mission to disseminate horticultural knowledge to professional horti-
culturists in the community. Another large part of our mission is academic research
and education. CUH is part of the College of Forest Resources at the UW and
boasts one of the largest bodies of undergraduate and graduate students in the
college.

A new undergraduate degree, Environmental Horticulture and Urban Forestry, made
a debut in the College this year. The three areas of concentration, environmental
horticulture, public horticulture, and urban forestry will provide the education,
experience and skills for profession in horticulture and related fields. Undergradu-
ates have expressed enthusiastic interest in the newly structured program.

The graduate program is more closely tied with the research and teaching at the
Center. Faculty guide students in programs such as environmental horticulture,
urban forestry, public garden management and education, curation, restoration
ecology, and plant conservation biology. Teaching and research takes place at the
Center, the Washington Park Arboretum and other sites around the Puget Sound.
Currently, there are 26 graduate students in residence, bringing a diversity of
experience that further enriches the Center.

If you are interested in learning more about the programs at the Center, please visit
or log on to our web site at http://depts.washington.edu/urbhort or call 206-543-

ProHort Seminars are planned and conducted cooperatively by the University of Washington Center for Urban
Horticulture and the Washington State University Cooperative Extension-King County Horticulture Program.
