By accident, I found out that Bug-Geta can damage daylilies and clematis vines. I had been using this product for years with great results on my perennials and annuals, but had never read the instructions until last week. Lo and behold, it said not to use it on Daylilies or Clematis. To date, thankfully, I haven't lost any daylilies, but I did nearly kill two of my favorite clematis vines.
Some of you may know this already, but I thought it worth mentioning here. I'm posting in the Clematis forum also.
