In Reply to: Sick Weeping Cherry Tree posted by Charlene on July 26, 2003 at 08:21:12:
: I have a weeping cherry tree that is very large; about 8 years old. It bloomed this spring, and produced leaves. However, the leaves hung wilted, and are now turning brown and falling off. The tree grew very quickly and developed a vertical split in the trunk that has gotten bigger over time, but never seemed to bother the tree before. Virtually no sap coming out of the split. There is a small area of healthy shoots coming from mid trunk that I would normally cut off, but have left thusfar until I know whats causing the problem with the tree. No apparent bugs or white residue. Any advice would be welcome.
To follow up with the cherry tree problem, I had a tree specialist view the tree. He wasn't able to give a positive i.d. of the problem, but suggested two things: 1. excessively wet/cool soil conditions of the spring without well drained soil, and 2. a fungal disease called verticillium wilt. There is no cure for the second, but to try to increase the tree's vigor through watering and fertilization. He drilled some small holes in the trunk of the tree and injected capsules of liquid nutrients. He further suggested that we water the tree, about 1"/week during dry periods this summer. There is no guarantee that this will save the tree, but is the best we can do for now. The vertical split in the trunk that I mentioned above is called "southwest injury", and is not generally harmful to the tree. Hope this may help others with the same situation.
