Re: Fwd: Nitrogen application rates


Book says mow at heights of 1 1/2 to 2 inches once a week and fertilization
rates vary from 2-6 lbs of nitrogen per 1000 square feet per year depending
on species. It also says that for blue grass and other cool season grasses a
high does of nitrogen in early spring can create disease problems so I would
lean more towards the 2 lbs per 1000 sq feet. Also says some researchers are
advocating a dose of fertilizer in fall for grass such as yours for a better
green-up in spring. So maybe 2lbs per in spring and 2lbs per in fall?
