Dahlias and Winter

Question

What should I do with my dahlias before winter? I live in the Pittsburgh area of PA. I planted them from seed and I’ve never seen plants explode in growth like them. I really love them but don’t want to dig them up. Should I cut them down? If so, to what height?

Answer 1

Unless you live in an area with mild winters, you need to dig up your dahlias. Here is an article or two that you may find helpful: https://www.gardeningknowhow.com/ornamental/bulbs/bgen/storing-bulbs-in-south.htm
