When to deadhead "Reblooming" Hydrangea and Iris?
Thanks for writing. Remove the flowers on both varieties as soon as they fade; it will help your hydrangea bloom faster and will increase your chances of seeing a rebloom on the iris. You can remove the entire bloom stalk on the iris; cut the hydrangea back to the first set of leaves under the flower head.
