Pruning and Propagating a Leggy Dieffenbachia (Dumb Cane)

Owner has 30-year-old Dieffenbachia (called mother-in-law tongue, but that's Sansevieria). Expert Will Creed: Dieffenbachia loses lower leaves, becomes top-heavy. Prune all leggy stems to 6 inches above soil; new growth emerges below cuts. Root top cuttings in water or moist soil after removing lower leaves. Air layering is another propagation method.
