Post-Bloom Care for Lilacs and Iris

A gardener asked if lilac flowers should be trimmed after blooming and what to do for iris after flowering.

Simple Maintenance

Tom said deadheading lilacs improves appearance but isn't necessary. For iris, cut the flower stalk (scape) about 4 inches above ground. Let leaves grow and collect sunlight until fall; they can be cut in wedges then, but he usually leaves them alone.

Minimal post-bloom care keeps these perennials healthy and ready for next year.
