Water thoroughly when the top 2-3 cm of soil feels dry. Ipomoea horsfalliae prefers consistently moist soil but dislikes waterlogged conditions. Reduce watering slightly during cooler months to prevent root rot.

Ensure good drainage to avoid issues.

Prune annually in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing stems to maintain shape and encourage vigorous flowering.

Lightly trim back overly long vines to manage size and promote bushier growth.

Propagate from semi-hardwood cuttings taken in late summer or early autumn. Select healthy stems, cut them to about 10-15 cm long, and remove lower leaves.

Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep moist and warm.

Repot young plants annually in spring, and mature plants every 2-3 years, or when root-bound. Use a slightly larger pot with fresh, well-draining potting mix. Ensure the new pot has adequate drainage holes.

Water well after repotting.
