Browning/dying branches on Globe Willow tree
We have a beautiful & full globe willow which is several years old. We recently trimmed it due to some wind/weather damage & branch over crowding. We trimmed after we had a lot of rain to make sure moisture wouldn't be an issue. It has been a couple weeks & all of the sudden about 1/2 of the tree has turned brown & the leaves have died. The tree is mature, but not sure of the age. Even during our worst drought, it remained green & hardy. We live in N. Texas . Can you help us? Judi K.

Willow Trees will bleed sap if pruned while they are actively growing. Pruning during dormancy is important.
I suspect that the open wounds, during damp weather has opened your tree up to a fungus or bacterial blight.
If this is the case, you can apply fungicide to the tree.
You may want to have the tree examined by a certified Arborist.
