Watering, pruning, propagation, and repotting details from plant data
Water consistently during the growing season, especially when establishing. Allow the top inch of soil to dry out between waterings. Reduce watering in cooler months.
Prune in late winter or early spring to remove dead or damaged stems and to shape the plant. Can be cut back hard to control spread and encourage bushier growth.
Easily propagated from seed sown in spring or from stem cuttings taken in summer. Division of established clumps in spring is also effective.
Repot container-grown plants every 2-3 years in spring, or when root-bound. Use a well-draining potting mix and a pot that is slightly larger than the previous one.
