My sycamore trees are dropping leaves like crazy. Even though they aren't getting any less water than normal in this drought...because I never water much where these trees are...and even though its the middle of July, they are shedding as if it were October. Is this "normal" or could it be the fact that we've had a month of dark days due to the smoke from forest fires? Or all of the above? This IS July isn't it? I haven't been in a coma have I?
