Q: I may have done a bad thing. I fertilized a 1300 square foot lawn with a bag of 28-0-3 which is supposed to cover 5000 square feet. Is there anything I can do to correct the problem or will I be looking at a dead lawn?

A: My bet is that you’ll simply have very fast growing grass. Despite your over-application, the main ingredients in lawn fertilizer are treated to be released over several weeks. I’d irrigate with an inch of water weekly so the soil is damp enough for the grass to use the fertilizer as fast as it can. Mow regularly and bag clippings so more nutrients are removed over time.
