Caterpillars - Yikes!
This is my first year with passionflowers and until last week I was fine with the idea that I would be sharing the leaves with caterpillars. Almost overnight the darn things wiped out every single leaf on my 10' vine! Will they kill the plant completely if I don't do anything? I hate to harm future butterflies but I don't want my vine to die - Help! What should I do?
