Hi! I have patches of hardy Chinese ground orchids (Bletilla) growing in my perennial beds and something (I'm guessing an animal) is causing weed-wacker-like damage to them. The stalks, leaves and all, are being chopped down at the base (ragged cuts) and even strewn a few feet from the actual patches. Strangely, surrounding plants such as peonies, poppies and columbines are not being attacked. No slime, so not slugs or snails. No leaf damage besides the fact that entire plants are being chopped down. I've seen the occasional mouse and raccoon in my yard in past years, but this is the first year that anything like this has happened to my orchids (which I've been growing for 10 years now). By the way, this only started happening about 2 weeks ago. Any help would be appreciated. Thanks!
