Something is eating my bougainvillea. It's a well established plant and heretofore was vigorous and beautiful. Both the leaves and the colored bracts are affected and at times the plant is nearly denuded. I can't seem to find a culprit. Any ideas?

Any number of insect pests could be responsible for this, including bougainvillea looper. We recommend using neem oil for pests. It is safe for animals and beneficial bugs but will kill any chewing bugs that may be present, even if you don't see them.
