Hello all, I had my lawn aerated yesterday by a well respected local company that happens to be owned by my two brothers and myself. I am a silent partner. They have been in the business for years, but just added core aeration services this fall. I know it is best to leave the plugs behind, and they did so. The problem is that the plugs are moist, as they asked me to water the lawn before they came. They told me that I used just enough water and that the plugs came out perfectly. As they were aerating, they were continually stepping on plugs and turning them into thick mud. In some places, multiple plugs were smashed down and looked like big mud pies. This mud is trapping my healthy grass underneath it. It doesn't look like it will be drying or disintegrating any time soon. Won't this mud permanently kill the grass underneath it? (I tried raking this mud away but the grass beneath is stuck in it. That mud isn't going anywhere). Years ago, I was digging a hole and inadvertently left a couple of shovels of dirt on top of healthy grass. A week later that grass was dead and never grew again. Isn't this the same thing? Am I worrying about nothing? I picture my lawn with a hundred bare spots..right where those "mud pies" are now. I would appreciate the opinion of someone other than my brothers, so that is why I am writing here. Thanks to all who answer!
