Can you divide bearded iris in spring?
A: August or September is the best time to divide and transplant irises, but you still can transplant them now. Your irises may not bloom this spring. Start dividing them by removing the entire iris clump. To make the rhizomes easier to handle, reduce the length of the blade foliage by half.
Should I deadhead irises?

Some irises may bloom twice a year if you deadhead properly. Break off the individual flowers on each flowering stem after they finish blooming.
