Watering, pruning, propagation, and repotting details from plant data
Keep soil consistently moist but not waterlogged. Water when the top 2-3 cm of soil feels dry. Reduce watering in cooler months to prevent root rot.
Ensure good drainage to avoid overwatering issues, especially for container-grown plants.
Prune to maintain shape and encourage bushier growth, especially when young. Remove any dead, damaged, or diseased branches promptly. Pinch back the tips of young plants to promote branching.
Pruning can also help improve air circulation.
Propagate by seeds sown indoors in early spring or directly outdoors after the last frost. Cuttings taken from healthy stems in late spring or early summer can also be rooted in moist potting mix or water.
Repot young plants annually or when they become root-bound, typically in spring. Choose a pot only slightly larger than the previous one. Use a well-draining potting mix.
Established plants may not require frequent repotting.
