IPM of Midwest Landscapes
The University of Minnesota's Center for Urban Ecology and Sustainability site has a reference called IPM of Midwest Landscapes that is absolutely invaluable for diagnosing and treating landscape pests. The site has information on pests and beneficial insects on trees and shrubs and turf, as well as details about IPM tactics, and up-to-date pesticide information. You can purchase a written copy of the book through the Web site, but the book itself is all on the site. Best of all, it was updated in 2007. This is definitely a site to bookmark.

Wiggle Worm Soil Builder
Have you ever tried worm castings as a soil conditioner? I had the opportunity to tour the production facility of Unco Industries, which produces not only bait worms, but also Wiggle Worm Soil Builder. I began to use these worm castings in my garden, and I'm firmly convinced that they are some of the best conditioners I've found.
As they tout on their Web site: "The nutrients in our earthworm castings are plentiful. Most importantly, these nutrients are perfectly balanced in two forms. One form can be immediately absorbed by the plant as if it were directly injected and the other is able to provide nutrition which slowly feeds the plant for long periods of time. This very cost effective because small amounts provide incredible results and last a long time." To find out more, visit: http://www.vermiculture.com/.
