Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist but not waterlogged. Allow the top centimeter of soil to dry out slightly between waterings. Reduce watering in winter to prevent root rot.
Ensure good drainage to avoid standing water, as this plant is sensitive to overwatering.
Prune to maintain shape and encourage bushier growth. Pinch back the tips of new shoots, especially after flowering.
Remove any spent flower stalks and yellowing or dead leaves promptly to keep the plant healthy and attractive. This also helps direct energy to new growth.
Propagate from stem cuttings taken in spring or early summer. Cuttings should be about 7-10 cm long and have a few leaves. Dip the cut end in rooting hormone and plant in moist potting mix.
Keep in a warm, humid location with bright, indirect light.
Repot every 2-3 years or when the plant becomes root-bound, typically in spring. Use a well-draining potting mix. Choose a pot that is only slightly larger than the current one.
Handle the roots gently to avoid damage during the repotting process.
