Sinapidendron frutescens prefers consistently moist soil but dislikes waterlogged conditions. Water thoroughly when the top 2-3 cm of soil feels dry to the touch. Reduce watering frequency during cooler winter months.

Ensure good drainage to prevent root rot, especially in containers.

Prune Sinapidendron frutescens in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches to maintain an attractive shape and encourage vigorous growth.

Light pruning can also be done after flowering to manage size and promote bushiness.

Propagate Sinapidendron frutescens from semi-hardwood cuttings taken in summer. Select healthy stems, cut them into 10-15 cm pieces, and remove lower leaves.

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

Repot Sinapidendron frutescens every 2-3 years, or when the plant becomes root-bound. The best time to repot is in spring. Use a slightly larger pot with fresh, well-draining potting mix.

Ensure the new pot has adequate drainage holes to prevent water accumulation.
