Exactly. They are almost impossible to grow grass under. At least Bermuda. I tried for two years to get Bermuda to grow under it, but it just wouldn’t take off. Trimmed the lower branches high so it got morning and evening sun etc.
I think I read something later that the silver maple because it is so shallow rooted puts out a natural herbicide to kill any grass under it so it won’t be a competition for its food and water.
We don’t have it anymore. High winds took it and our Bradford Pear tree down a few years ago.
