I have an on going battle with a really nasty type of thistle in my butterfly garden. The animals don't like it and it chokes out my wildflowers. Today I was reading on the internet about weed eating the thistle, so that's what I did today. I hope I didn't upset the balance of my garden. Things are just beginning to come up as it has not been that warm. Tomorrow I will do some reseeding. I hope the thistle that I cut will just dry up. I can't rake due to knew seedlings coming up. Help!
