My clients JM's leaves are dying. He said they grew green early in the year and now they are dying. I went and checked the soil and it seems beautifully moist. Definitely not too wet and not dry. The only thing I can think is the crazy weather we've had in northern California this year. We had a heat wave at the end of winter with temps at almost 100°. Then cold and torrential rain then hot and back and forth like that. Maybe the weather is causing stress??
