Regular deadheading of any plant promotes healthier growth.
Deadheading irises, which involves removing spent flowers, is essential for maintaining plant health and aesthetics. And did you know that some iris will bloom a second time in a season if deadheaded as soon as possible after bloom?
The optimal time to deadhead irises is immediately after the flowers begin to fade and wither, typically in late spring to early summer depending on the variety and climate.
Throughout the blooming season, regularly check your irises and remove individual spent flowers to encourage new blooms and prevent the plant from directing energy toward seed production.
Once all flowers on a stalk have bloomed and faded, cut the entire flower stalk down to the base of the plant. Use clean, sharp scissors or garden shears to make precise cuts, ensuring not to damage the foliage or emerging buds. Properly disposing of spent flowers and stalks helps prevent disease spread and keeps the garden tidy.
