Water Cochlospermum planchonii thoroughly when the top inch of soil is dry. Allow the soil to drain completely between waterings. Reduce watering significantly during the dormant winter period.

Overwatering can lead to root rot, so err on the side of caution.

Prune Cochlospermum planchonii in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain shape and encourage robust flowering.

Pruning can also be done to control size.

Propagate Cochlospermum planchonii from seeds sown in spring or from semi-hardwood cuttings taken in summer. Seeds require warm temperatures and consistent moisture for germination.

Cuttings need to be kept in a humid environment.

Repot Cochlospermum planchonii every 2-3 years or when it becomes root-bound. Use a well-draining potting mix. Repotting is best done in spring before the active growing season commences. Water lightly after repotting.
