Propagating prayer plants is surprisingly easy. Some Maranta species can be propagated by stem cuttings or rhizome division. The most common (and easiest) way to propagate this plant is by division at repotting.Division: When repotting, you can divide your prayer plant into several smaller plants by gently shaking the soil off the roots and working them apart. Each new plant should have a good mass of roots and several stems. Pot these new smaller plants up separately in small, shallow pots. Keep new divisions very warm and moist during the first few weeks until new growth emerges.Cutting: Make a stem cutting below a leaf node. Dip the cutting in a rooting hormone and place it in a glass of water, making sure to change the water every two days or so. Once roots form, place the cutting directly into potting soil. Keep the soil moist and mist the plant from time to time.
You should not need to repot your prayer plant often. But, if it becomes root-bound or pot-bound, it will grow much slower. If you repot, choose a pot that is only one to two inches wider than the existing pot. During repotting, gently remove the plant from its old container, shake roots clean, and place into a new container with fresh potting soil. Water well. The best time to repot is in the spring before the growing season starts.
