Hi All, I am a property mgr and recently hired a lawn care professional to resurrect one of my lawns. After aerating, he applied a "top dress" of some "planters mix" to the grass which is full of dandelions. He then applied seed. The plan is to get some more grass coming in and then attack the weeds. Anyway, the top dress material has a significant amount of small stones (1/4'-3/8") or so in size. I know some of this will "disappear" once the lawn fills in but I am worried that those stones will get into the mowers and become a real problem. Could really use some advise here. Thanks!
