2 weeks ago I dethatched my lawn and about a week ago I top seeded it. A friend of mine just bought a plug aerator...is it too late to aerate the lawn? I live in Western Massachusetts. Also, if I do aerate it do I leave the plugs and mulch them in or rake them up?
i would wait until spring to aerify unless you want to reseed. leave the plugs and try to drag or rake them it unless you have a soil problem and are planning to topdress with fresh material. rule of thumb is to fertilize after first mowing.
