I'm one of the few people in NW Florida crazy enough to try the new "Low-Chill" Cherry trees. I've got 8 of them and they are in their 2nd year. They were doing great until one of them started to get the brown spots and then the leaves would turn yellow and fall off. It's a pretty common problem here. I came at it first with Neem Oil. I wanted to try to stay as organic as I could. And I've been keeping it really clean under the tree so the spores don't get me next year. But when the all started to get it, I had to break out the big guns. I've been using Immunox multi-purpose fungicide. But it's not doing any good.
Anyone have any better suggestions before the spring brings me to another round of fights?

If it is one of the fungus diseases that spreads in the fall and winter, spray then. That is, right now.

Try copper. It may be a bacterial leaf spot.

Was a good call drobarr! They all filled with leaves and got a ton of blooms this year. Just waiting not to see if it stays healthy. 2 of them seemed to drop their leaves overnight. But I didn't see those spots. It might just be too humid here but I'm not ready to give up yet.
