I applied commercial compost and hardwood mulch to an area where I am establishing a small garden. I did a few soil tests on the area and the results indicated the nitrogen was depleted. I intend to spread a bag of dried blood to rectify this problem When is the best time to apply the dried blood?
Landscape professionals are usually skeptical about results from home soil tests. They don’t always produce accurate results unless you take a large soil sample from many parts of your yard.
“Take your home soil test results with a grain of salt,” advises Tony Fulmer, manager, Chalet Nursery, Wilmette. He cautions not to become overly excited by the results. “Hard-wood mulch is used by landscapers all over the area, and I don’t see a problem with it causing nitrogen depletion.”
Apply the dried blood now. The 12% insoluble nitrogen starts working when soil temperatures rise.
