I thought it might be worthwhile having a thread running to deal with problems in general - where one could go to post problems they are having and see what resolutions might be there. I didn't see anything of that sort, so I thougth I might post something for a starter.
JM Problems and Care
What do I do when trees have been over-watered? I've had a few that have wilted. I didn't know what to do. I tried a fungicide - assuming that might be it. But it didn't work.
Pictures will have to wait until a next time it happens, if it does.
If your tree has been overwatered the plant has drowned or gotten root rot it's toast play taps and bury it..David
I agree with David, if the wilting is due to a fungus or crown rot then it's too late to save it. Wish that I had a better answer for you.
