Leaf propagation is a common method of growing new plants from leaves

Leaf propagation is a method of growing new plants from the leaves of a plant. It is a form of asexual reproduction and is also often called leaf cutting or leaf propagation. Leaves contain tissues with strong meristematic capacity, and under suitable temperature and humidity conditions they can produce adventitious roots and adventitious buds, gradually developing into a complete new seedling.

Leaf propagation is simple to do and low in cost, requiring no complicated tools, so ordinary households can carry it out. Because it is a form of asexual reproduction, the new plant basically retains the varietal characteristics of the mother plant, making it suitable for gardening enthusiasts who want to increase their numbers without buying seeds or seedlings.

Not all plants are suitable for leaf propagation; usually species with thick, fleshy leaves and strong regenerative ability have a higher success rate, such as common succulents, snake plant (Sansevieria), begonias, African violet (Saintpaulia), and gloxinia (Sinningia). The methods can be divided into soil culture leaf cuttings and water culture leaf cuttings; the former involves inserting the leaf obliquely or laying it flat on a slightly moist substrate, while the latter only requires the base of the leaf stalk to touch the water surface slightly.

During leaf propagation, attention should be paid to keeping the environment warm and humid, with bright light but avoiding direct sun exposure, and the substrate should be kept drier rather than wetter to prevent the leaves from rotting and turning black. Rooting and sprouting take some time, so patience is all that is needed; slight depletion of the old leaf during this period is normal. If a leaf is found to have turned to water or become moldy, it should be removed and dealt with promptly so as not to affect the other leaves.
