Cutting back Columbine
Have had great large columbines for years and never did anything to them after blooming except to harvest seed.
Started a woodland garden 3 years ago with lots of columbine. They are huge and crowding out other plants.
Can I cut them back, if so how far. I love them and don't want to lose them. Have transplanted some still in bloom, but they are so big I'm afraid of injuring the taproot.
