Do Gerbera Daisies Need to Be Deadheaded?
Certified GKH Gardening Expert
Yes, you can deadhead these plants. That being said, rather than simply pinching back the spent blooms, for daisy varieties that produce single stems per flower, such as Gerbera,, it’s better to cut the individual stem back to the base of the plant. If all the blooms are spent, simply cut the entire plant back to the base. This will stimulate new growth and additional flowering.
