Besides the birds I feed the squirrels, I nailed a feeder to the tree and keep it filled with peanuts, walnuts and a
occasional peanut butter sandwich, and I have never ever had a problem with them at my bird feeders, and I
think it is because I feed them well, so hopefully anything I plant they leave alone, but if I do plant something I
think they will mess with I will MAYBE use some cayenne pepper....I have 2 dogs that go in the yard.
