I have found that what seems like adequate watering during normal times falls far short in a very hot, dry year such as this. Information about fall needle drop, drought, and proper watering can be found in the links below. The current drought is severe and has expanded into most of southwest Ohio. The good news is that there are decent rain chances in the coming weeks. However, I will believe it when I see it. For now, continue watering and hope the rain comes through.
