Cleome aculeata prefers consistently moist soil but dislikes waterlogged conditions. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering frequency during cooler months or when the plant is dormant.

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

Pruning Cleome aculeata is primarily done to shape the plant and encourage bushier growth. Pinch back the tips of young stems to promote branching. Remove spent flowers (deadheading) to encourage continuous blooming.

Prune back significantly in late winter or early spring to rejuvenate the plant.

Cleome aculeata is easily propagated from seeds sown indoors in early spring, about 6-8 weeks before the last frost. Germination typically occurs within 1-3 weeks.

Transplant seedlings into the garden after the danger of frost has passed. Division of established clumps in spring is also possible.

Repot Cleome aculeata annually or biennially, preferably in spring before new growth begins. Choose a pot that is one size larger than the current one, ensuring it has ample drainage holes.

Use a well-draining potting mix. Repotting helps to refresh the soil and provide more space for root development.
