I am sure squirrels are eating my tulip buds. The stems are pretty tall and we do not get groundhogs or gophers. It is just disheartening as they're about to open, the buds are eaten cleanly off the stem and the petal are strew everywhere. Almost like a cruel joke. :( Is there a way to deter these squirrels? I've sprinkled cayenne pepper and blood meal but it only works until it rains.
