Pruning blue columbine — FAQ
When should I prune blue columbine?
After flowering, early to midsummer. Remove spent flower stems at the base once blooms fade. If the foliage yellows and collapses after bloom, cut the whole clump to ground level — it will regenerate. Divide overgrown clumps in early spring every few years.
How often does blue columbine need pruning?
Deadhead during flowering season; cut back once annually after flowering. Blue Columbine (Colorado's state flower) needs minimal pruning. Deadhead spent flowers to reduce self-seeding or leave them for birds and natural re-seeding. Cut the whole plant back to its basal rosette after flowering when foliage declines. Fresh growth will emerge in late summer.
