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.

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.
