What are the most common soil-borne diseases in the Pacific Northwest?

There are four soil-borne diseases common to this area: oak root fungus, verticillium wilt, Phytophthora, and Texas root rot.

What can I do about verticillium wilt?

Verticillium wilt is caused by fungi in the soil that may persist for many years. There is no known treatment that will guarantee the safety of wilt-susceptible, deep-rooted trees and shrubs, but thorough fumigation has been found to make the soil safe for the growing of shallow-rooted plants.

My new homeowners' association won't allow me to build a fence. How can I create more privacy in my yard?

Many communities do not allow fences in visible areas, and they may also create more of a barrier between you and your neighbors than you really want. There are many landscaping options available that provide privacy. Consider these:

bulletArbors. An simple structure covered with vines will provide overhead protection and will often not fall under the regulations that forbid the erection of fences.
bulletBerms. A mound of soil planted with trees and shrubs will provide privacy and buffer noise.
bulletHedges. When kept properly clipped, hedges are excellent privacy screens that also act as barriers to wind and noise.
bulletTrees. A single mature tree will offer higher line-of-sight privacy than other options.

Decorative plantings will soften the appearance of solid barriers.

How can I buffer my lovely garden oasis from ugly street noise?

While fences can provide privacy from prying eyes, most do not offer much protection from noise. Reinforce your fence with natural privacy plantings to create a wide and varied buffer zone between your garden and the street.
