Q.What to do to save old magnolia tree believed poisoned last year?
I have a large Magnolia tree that I believe may have been accidentally poisoned last year when my husband was spraying for weeds in a pasture near the tree. Leaves are sparse (several branches don’t have any leaves) & I have no blossoms this year on it. Is there anything I can do to save it and/or help it to recover?

Your state's extension service is your best resource on this. They will ask you what kind of poison was used, how long ago, etc.
