How to get rid of Ranunculus ficaria (lesser celandine)?
I have a wooded area that is infested with Ranunculus ficaria and I want to get rid of it or at least contain its spread. They do disappear in the summer but they are crowding out celandine poppies and other early spring flowers. Any advice is welcomed especially if you have successfully done this. I normally would prefer a more manual solution since I am mindful of runoffs but I heard that this one is hard to do by hand. So I am open to chemicals. Thanks!
