Water the plant when the top inch of soil feels dry to the touch. Be sure to water the soil and not the leaves to avoid fungal diseases.
Fertilization
Begonias need regular fertilization to maintain healthy growth and vibrant foliage. During the growing season, apply a balanced liquid fertilizer every 2-3 weeks.
Make sure to follow the manufacturer's instructions on the product label. It is also important to avoid overfertilizing as this can lead to burnt roots and damaged foliage.

Water the cutting thoroughly and keep it in a warm, bright location. New plantlets should develop from the base of the leaf in a few weeks.
Propagation by Division
Propagation by division is another method of propagating Begonia cultrata Irmsch. This method is ideal for mature plants that have developed more than one crown. Carefully remove the plant from its pot and gently separate the individual crowns. Plant each crown in a separate pot and water it thoroughly. Keep the pots in a warm, bright location and water regularly until the plants are established.
Begonia cultrata Irmsch. is a highly decorative plant that can be propagated easily at home through stem cuttings, leaf cuttings, and division. With the right care, these propagation methods can help you grow a beautiful and healthy Begonia cultrata Irmsch. plant.
