I have some very old cherry trees that are prolifically dropping leaves that are yellow and orange with black spots. It looks more like Autumn underneath them. Does it have something to do with all our rain and cool weather or is it something else?

Not enough water will harm a tree but so will too much as excessive moisture drives oxygen out of the soil and roots need it to survive. So to answer your question, YES too much rain can be the causing issue. Dig down a few inches to feel the soil and assess what the moisture content is then adjust watering accordingly. Your tree may be suffering from a foliar disease. Take some samples to your County Extension Office and see if they can identify the problem and if necessary prescribe an appropriate remedy. Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
