Deadhead Hollyhocks Like A Pro With These Helpful
Garden Tips
Reaching heights of up to 9 feet, hollyhocks are majestic giants that grace you with their elegance between June and August, bringing a mighty splash of splendor to your garden.
To give them the best chance to show off their magnificent blooms into late summer or even early fall, it’s necessary to deadhead them, meaning remove wilted or dead flower heads.
You should deadhead your hollyhocks as soon as the flowers start wilting. Deadheading energizes the plant, so it keeps reblooming; however, it also deters self-seeding.
If you want your hollyhocks to multiply through self-seeding, pause the deadheading until the flowers get brown. If their pods are full of seeds, remove them and plant the seeds.
The flower stalks carry multiple heads that bloom at different times. Pinch off the wilting flower buds from the bottom of the stalk, while the heads further up will still bloom.
When three-quarters of the top heads have bloomed, snip them at the base with your pruning shears. New flower stalks will grow — maybe not as tall, but just as vibrant.
