Water thoroughly when the top 5-7 cm of soil is dry. Cochlospermum adjanyae prefers well-draining soil and is susceptible to root rot if overwatered.

Reduce watering significantly during cooler, dormant periods to prevent waterlogged conditions. Ensure good drainage to avoid stagnant water.

Prune to shape the plant, remove dead or damaged branches, and improve air circulation. The best time for pruning is after flowering has finished.

Heavy pruning can be done to maintain a desired size or encourage bushier growth. Remove any crossing or inward-growing stems.

Propagate primarily through seeds, which require scarification or soaking before sowing. Cuttings can also be taken from semi-hardwood in late summer.

Ensure cuttings are treated with rooting hormone and kept in a warm, humid environment for optimal success. Germination can be slow.

Repot young plants annually or every two years, and mature plants less frequently, typically when root-bound. Use a well-draining potting mix, such as a blend of potting soil, perlite, and sand.

Repot in spring before new growth begins. Choose a pot only slightly larger than the current one.
