If you don’t have a spot like that in your home, you can use artificial lighting to provide the right amount of light for your plant.

Propagation of Chain Sword Plant by Stem Cuttings

To propagate your plant by stem cuttings, first fill a small pot with fresh potting mix and moisten it well. Next, take a 4-6 inch cutting from the tips of healthy stems, making sure each cutting has at least two sets of leaves. Remove the bottom set of leaves from each cutting, dip the cut end in rooting hormone (optional), and then insert the cutting into the prepared potting mix. Water well and place the pot in a warm, bright location out of direct sunlight. Keep the soil moist but not soggy until new growth appears.

Suitable Time For Propagation of Your Chain Sword Plant
