Question:
Should I fertilize the lawn in summer?Answer:
Do not fertilize Kentucky bluegrass and other cool-season grasses during the summer months (June, July, and August). The best times to fertilize cool-season grasses in Iowa are spring, mid-September, and late October/early November. When fertilizing the lawn, do not apply more than 1 pound of actual nitrogen per 1,000 square feet in one application.
