Q.Weeping Cherry
We moved into a new home and it has an old weeping cherry tree. I have discovered tent caterpillars have hatched and are having a great time eating the leaves. There is a lot of old dead growth on the tree too. Is there something I can do to control the damage until pruning season? Of course, I am inclined to cut it down and start all over.

Here is an article that will help you on how to deal with tent caterpillars. Good luck!
