Acorns Aplenty - bad for lawn?
I live in a beautiful neighborhood with huge, stately pin oak trees, with "acorns aplenty". Some windy nights it's been like sleeping under a pinball table. Walking on the front yard is like getting a foot massage (wearing sneakers, and not bearfoot!).
Question: Is it "bad" to leave many (thousands) acorns on/in the grass? Will they make the soil too acidic perhaps?
