Water Brachychiton bidwillii thoroughly when the top few centimeters of soil feel dry. Allow soil to dry out slightly between waterings. Avoid waterlogging, especially during cooler months.

Reduce watering significantly in winter to prevent root rot.

Prune Brachychiton bidwillii to maintain shape and remove any dead, damaged, or crossing branches. Pruning is best done after flowering or in late winter before new growth begins.

Avoid excessive pruning, as it can reduce flowering.

Propagation is typically done from seed, which may require scarification or soaking before sowing. Grafting is also a successful method for propagating specific cultivars. Layering can be attempted, but is less common.

Repot young plants annually or every two years in spring. Mature plants can be repotted less frequently. Use a well-draining potting mix.

Choose a pot that is only slightly larger than the current root ball to avoid overwatering.
