Water
Keep the soil consistently moist but not waterlogged. Water when the top 1-2 cm of soil feels dry. Avoid letting the plant sit in standing water, as this can lead to root rot.
Reduce watering slightly during cooler, dormant periods.

Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist but not waterlogged. Water when the top 1-2 cm of soil feels dry. Avoid letting the plant sit in standing water, as this can lead to root rot.
Reduce watering slightly during cooler, dormant periods.
Pinch back growing tips regularly to encourage bushier growth and more blooms. Remove spent flowers promptly to prevent seed formation and encourage further flowering.
Light pruning can be done any time to shape the plant.
Easily propagated from seed. Sow seeds thinly on the surface of a well-draining seed-starting mix in spring. Keep consistently moist and warm, providing bright, indirect light.
Germination typically occurs within 2-4 weeks.
Repot young plants annually in spring to provide fresh soil and more space. Mature plants can be repotted every 2-3 years or when root-bound. Use a well-draining potting mix, such as a blend of peat moss and perlite.
