Taking care of your lawn during the fall is as important as it is during spring and summer, even more so for lawns with cool-season grasses such as Kentucky bluegrass and tall fescue. Nearly all fertilizers and broadleaf herbicides should be applied in the fall, and it is by far the best time to renovate (seed) lawns. Here are some tips for cool-season grasses:
Fertilize - fertilizing your lawn in the fall will help it grow stronger, thicker and greener.
Cool - season grasses should be fertilized with nitrogen in late October and again in four to six weeks. Use either farm fertilizers such as ammonium nitrate or urea, or use specialty fertilizers found in garden centers. The normal rate is 1 to 1.5 pounds of actual nitrogen per 1,000 square feet of lawn. A common rate would be 15 pounds of 10-10-10 fertilizer per 1000 sq. feet. Remember to spread it evenly over your lawn.
