Water Oroxylum indicum regularly, ensuring the soil remains consistently moist but not waterlogged. Allow the top inch of soil to dry out between waterings, especially during the growing season.

Reduce watering in cooler months, but never let the soil become completely dry. Good drainage is crucial to prevent root rot.

Prune Oroxylum indicum to maintain its desired shape and size, and to remove any dead, damaged, or crossing branches.

Light pruning can be done at any time, but heavier pruning is best performed in late winter or early spring before new growth begins. This encourages bushier growth and better flowering.

Propagate Oroxylum indicum from seeds sown in well-draining soil mix, ideally in spring. Seeds may require scarification or stratification to improve germination rates.

Cuttings can also be taken from semi-hardwood in summer and rooted in a humid environment with bottom heat. Patience is key for successful propagation.

Repot Oroxylum indicum every two to three years, or when it becomes root-bound. Use a well-draining potting mix, preferably containing sand or perlite. Choose a pot that is only slightly larger than the current one.

Repotting is best done in spring, just as new growth begins, to minimize transplant shock.
