Watering, pruning, propagation, and repotting details from plant data
Water consistently, keeping the soil evenly moist but not waterlogged, especially during the growing season. Reduce watering in winter, allowing the soil to dry out slightly between waterings.
Avoid overhead watering to prevent fungal diseases. Ensure good drainage to prevent root rot.
Prune in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches. Lightly shape the plant to maintain its desired form and encourage bushier growth.
Pruning can also help manage size and promote flowering.
Propagate by seeds sown in spring or by stem cuttings taken in late spring or early summer. Seeds may require stratification.
Cuttings should be treated with rooting hormone and placed in a well-draining medium in a warm, humid environment. Patience is key for success.
Repot young plants annually or every two years in spring. Mature plants can be repotted less frequently, every 3-4 years, or when root-bound. Use a well-draining potting mix.
Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
