Choose a healthy stem with at least one leaf and make a clean cut below the leaf node. The cutting should be around 4-6 inches long.
Once you have prepared the cutting, dip it into rooting hormone powder and plant it into a pot filled with a moist and well-drained potting mix. Cover the pot with plastic or glass to maintain humidity, and place it in a warm place that receives indirect light.
Within four to five weeks, the cutting should have formed roots. You can remove the cover and transplant the cutting into a bigger pot.
Overall, Dorstenia psilurus Welw. var. psilurus is an easy-to-grow plant that can be propagated through seed and cutting propagation techniques.
