The Q&A Archives: Stimulating New Growth on Lower Part of Dieffenbachia

Question: My dieffenbachia has grown to well over 6 feet tall. However, the bottom 3 feet of the stem is bare. How can I stimulate new leaf growth on the stem? I have often air-layered which produces roots. (I then cut off the top and plant it.) I want new leaves all the way down to dirt level! LouAnn Ross Louisville, KY

Answer: The only possible way to stimulate new growth on the bottom of your dieffenbachia is to prune it below the foliage to stimulate the dormant buds along the stem. It will look like a stick for awhile, but eventually will regrow new leaves. When you're growing the plant, be sure it gets enough light on the bottom leaves, so they don't drop. Loosing the lower leaves is normal, by the way.
