Water Gossypium arboreum regularly during the growing season, keeping the soil consistently moist but not waterlogged. Reduce watering in autumn and winter, allowing the soil to dry out slightly between waterings.

Overwatering can lead to root rot.

Prune Gossypium arboreum in late winter or early spring to shape the plant, remove dead or damaged branches, and encourage bushier growth. Light pruning can be done throughout the growing season to maintain desired size and remove spent flowers.

Propagate Gossypium arboreum from seeds sown in spring after the last frost, or from stem cuttings taken in late spring or early summer. Seeds germinate best in warm, moist soil.

Cuttings root readily in a well-draining potting mix.

Repot Gossypium arboreum every 2-3 years, or when it becomes root-bound. Use a well-draining potting mix. The best time to repot is in early spring before new growth begins.

Choose a pot only slightly larger than the current one.
