Deadheading is an essential gardening practice that encourages continuous blooming and keeps your garden looking vibrant. For columbine (Aquilegia), deadheading throughout the growing season can promote more flowers and prevent unwanted self-seeding. This guide provides a month-by-month schedule to help you deadhead your columbine effectively.
Early Spring (March – April)
As the weather warms and new growth emerges, inspect your columbine plants regularly. Remove spent flowers as soon as they fade to encourage new blooms. Use clean, sharp scissors or pruning shears to make clean cuts just above the foliage.
Mid to Late Spring (May – June)
During peak blooming season, deadheading should be a weekly task. Remove all faded flowers to prolong flowering. Pay attention to any seed heads forming and prune them if you want to control self-seeding. This helps the plant focus energy on producing new flowers.
Summer (July – August)
In summer, continue deadheading to maintain a tidy appearance and promote additional blooms. Some varieties may naturally fade, but regular removal of spent flowers can extend the flowering period. Be cautious of heat stress; avoid deadheading during the hottest part of the day.
Fall Preparation (September – October)
As the growing season winds down, deadheading is less critical but still beneficial. Remove any remaining spent flowers to prevent seed formation if you wish to control spreading. After flowering ceases, cut back the plant to about 2-3 inches above the ground to prepare for winter dormancy.
Additional Tips for Deadheading Columbine
