Water Sterculia alata thoroughly when the top 5-10 cm of soil is dry. Avoid overwatering, as this can lead to root rot. Reduce watering significantly during winter months when the plant is dormant.

Ensure good drainage to prevent waterlogged conditions.

Prune Sterculia alata to maintain desired shape and size, and to remove any dead or diseased branches. Light pruning can be done any time of year.

For more significant shaping, prune in late winter or early spring before new growth begins.

Sterculia alata can be propagated from seeds, which require warm temperatures for germination. Cuttings are also possible but can be challenging to root. It is best to propagate in spring or early summer.

Repot young Sterculia alata plants every 2-3 years, or when they become root-bound. Mature plants may only need repotting every 4-5 years.

Use a well-draining potting mix and choose a pot one size larger than the current one.
