1. Take a Stem Tip Cutting of Chinese Evergreen Plant

Pick a stem with a node. Cut a 3 inch long stem.

2. Place Chinese Evergreen Stem in a Jar of Water

Place the Chinese Evergreen stem into a jar of water and wait for it to grow roots. To help it focus its energy on growing roots, make sure your stem has a maximum of 2 leaves. Cut off extra leaves as needed.

Another way to stimulate root growth is to dip your stem cutting in root hormone and plant it in moist sand. I personally prefer the jar method so you can easily see the roots come out. Know that not all stem cuttings of Chinese Evergreen will grow roots, so to be safe, cut a few stem cuttings so you will at least get one with roots.

3. Plant Stem Cutting in a New Pot

Once the roots grow, plant these stem cuttings into a new pot. Water the new plant immediately after planting. Then water every 2-3 days until the roots are established.
