How to propagate Wax Begonia from stem cuttings

Take a 3-4 in. stem cutting from a healthy Wax Begonia plant from low down the plant as cuttings from low down the plant root more easily.

Strip off the lower leaves of the Wax Begonia Cutting and insert the cutting in moist free-draining soil.

Cover the set up with a clear plastic bag to create a greenhouse effect to hasten rooting.

Place the set up in a warm shaded place and maintain the soil moist until the Wax Begonia cutting has rooted.

Once rooting has taken place, gradually remove the clear plastic to acclimatize your new Wax Begonia plant.
