Q.How do I save a weeping cherry blossom tree that was sprayed with Raid wasp & hornet killer?
Hello, this tree is very special to me and it was sprayed about a month and a half ago in an attempt to kill Gypsy moth nests. Most of the limbs have brown leaves. Please tell me there’s something I can do to save it!!

It is not likely that the insecticide is the reason for leaf browning. The materials in that product are normally not phytotoxic. There must be another factor, water deficit/drought stress? Soil/root disturbance? Is it a recently planted or transplanted tree that could be suffering from transplant shock? Herbicide (week killer) used on a lawn or nearby area?
