I'd let the leaves fall off on their own.

What kind of soil do you have these trees planted in? When did you repot? When did you fertilize and with what?
Do you have a neighbor that may have been spraying a herbicide around? Are these guys in full sun? Any one or all of the above could be the problem. Generally a air born fungus will not cause the kind of problem you are having, a soil born fungus is another matter, the reason for the soil question.

My trees died. These were very small 1 and 2 year old grafts, without much in reserve to fight/recover. Your tree is larger, but that doesn't mean your tree will fair any better, based on its current condition. I agree with Vance. If similar symptoms are affecting another tree, I would definitely consider a soil issue, as well as the location of the trees.

The Japanese maple that is pictured at the top of the thread is in bonsai soil that I bought from a nursery. I couldn't say what the make-up of the soil is. I'm not that knowledgeable about soil yet. It does need to be repotted though. There's wire on that large root that's visible that needs to be removed. I could try repotting it and putting it into new bonsai soil. That might stress the tree more though...
I guess a good starting point might be to spend some time learning about soil and trying to figure out what kind of soil it is in. The other tree, the trident maple, is in potting soil. Infact it's still in the same deep growing pot that it was in when I got it from the nursery. |
