Propagation of Brillantaisia grandidentata S.Moore
Propagating Brillantaisia grandidentata S.Moore is relatively easy and can be done by different methods. Two commonly used methods are through stem cuttings and seed propagation.
Propagation through stem cuttings
Stem cuttings can be taken from the mature plant during the active growth period, which is typically from spring to early summer. Cuttings should be from the current season's growth and should be about 10-15 cm long. Remove the lower leaves from the bottom one-third or half of the stem. Dip the base of the cutting into rooting hormone powder and plant it into a free-draining soil mix in a pot or container. Keep the soil moist and provide adequate light and warmth. The cutting should root in about 4-8 weeks, after which it can be transplanted into its permanent location.
Propagation through seed
Brillantaisia grandidentata S.Moore can also be propagated from seed. Collect the seeds from the plant when the seed capsules have dried and turned brown. Sow the seeds immediately into a well-draining soil mix in a pot or container. Sow the seeds at a shallow depth and cover them lightly with soil. Water the soil well and keep it moist. Place the pot or container in a warm and bright location but out of direct sunlight. The seeds should germinate in about 2-4 weeks. Once the seedlings have grown to about 10 cm tall, they can be transplanted into their permanent location.
