This is my first year mowing alone. I had a customer ask about aerating and putting down fertilizer and seed. My question is after I aerate the lawn and put some fertilizer down with the seeds will I need to cover it with straw or compost? Or since I aerated just lay the fertilizer down and seed and let it go. Going to do this end of Sept first of Oct I'm in central pa and was wondering whats a good fertilizer to put down and good seed?
