Dividing autumn fern
I have a lot of healthy autumn ferns, and I divided them successfully a few years ago. I'd like to do it again, but I'm not sure when is the best time. I want to make sure I do it before they start growing, but I don't want to do it too soon if the cold weather is a risk factor

The best time is early spring. You may want to wait until you see some new growth so you can locate the entire clump and divide as needed.
