Watering, pruning, propagation, and repotting details from plant data
Water regularly, especially during dry spells, to maintain consistently moist soil. Avoid waterlogged conditions, which can lead to root rot.
Once established, it exhibits moderate drought tolerance but performs best with adequate moisture.
Prune immediately after flowering in late spring or early summer. This encourages vigorous new growth for the following year's blooms. Remove dead, damaged, or crossing branches at any time.
Avoid late-season pruning to prevent winter damage.
Easily propagated from softwood cuttings taken in late spring or semi-hardwood cuttings in mid-summer. Root cuttings in a well-draining potting mix, keeping them consistently moist and in a humid environment until established.
Container-grown plants may need repotting every 2-3 years to refresh the soil and accommodate root growth. Choose a pot one size larger with good drainage. Repot in early spring before new growth emerges.
