Arizona Water-Willow thrives in consistently moist soil. Water deeply when the top 2-3 cm of soil begins to dry. Avoid waterlogged conditions, but do not allow the soil to dry out completely.

Reduce watering slightly during cooler months, but maintain adequate moisture, especially if grown in containers.

Prune Arizona Water-Willow in late winter or early spring before new growth begins to shape the plant and remove any dead, damaged, or crossing branches.

Lightly prune throughout the growing season to encourage bushier growth and more flowers. Pinch back leggy stems to maintain a compact form.

Arizona Water-Willow can be easily propagated from stem cuttings taken in spring or summer. Select healthy, non-flowering shoots, and dip the cut end in rooting hormone.

Plant the cuttings in a well-draining potting mix and keep them consistently moist and in a warm, bright location.

Repot young Arizona Water-Willow plants annually in spring, or when they become root-bound. Choose a pot that is one size larger than the current one, using a well-draining potting mix.

Mature plants may only need repotting every 2-3 years to refresh the soil and provide adequate space.
