Watering, pruning, propagation, and repotting details from plant data
Water deeply when the top 2-3 cm of soil feels dry. Ensure good drainage to prevent waterlogging, which can lead to root rot. Reduce watering significantly during the dormant winter months.
Overwatering is a common mistake, so err on the side of caution.
Prune in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain shape and promote air circulation.
Light pruning can be done after flowering to remove spent blooms, but avoid heavy pruning.
Propagate by seed sown in autumn or early spring, or by division of established clumps in early spring. Seeds may require a period of cold stratification.
Division is generally the most successful method for home gardeners.
Repot young plants every 1-2 years, and mature plants every 3-4 years, or when root-bound. Use a well-draining potting mix. Repot in early spring before new growth appears.
Choose a pot only slightly larger than the current one.
