diffenbacia plants

Question

I have a diffenbacia plant that is about 3-4 years old. some of the stems are growing out in all directions. Is this normal? How would you suggest cutting them back.

Answer 1

Yes, it's normal for dieffenbachias to become large and unruly eventually, but you can prune them back. When pruning, you can remove up to 1/3 of the plant's total size at any one time. You can entirely remove individual stems, or you can cut a stem back part way to encourage more bushy growth close to the center of the plant.
