My husband is terrible with his weed eater. He chewed up my little peach tree that would not grow or bloom or do anything since I planted it 6 years ago. And I have watered and fertilized it just like the others. Well this year it bloomed and has new top growth and a few little peaches on it! The reason... DH chewed into half the bark on one side of the tree, forcing it to bloom and put out new growth!
I told DH he did a good thing this time but I was going to buy some aluminum plates to put around the trees to protect them from his weed eater.
