Water Thunbergia alata regularly, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings, especially during warmer months.

Reduce watering in cooler periods. Consistent moisture encourages lush growth and abundant flowering.

Prune Thunbergia alata to maintain shape, encourage bushier growth, and remove spent flowers. Pinch back tips regularly to promote branching. Prune lightly after flowering to encourage a second bloom.

Heavy pruning can be done in late winter or early spring before new growth begins.

Propagate Thunbergia alata from seeds sown indoors in spring, or from stem cuttings taken in summer. Seeds germinate best with warmth and light. Cuttings root readily in moist potting mix or water.

This easy propagation makes it simple to start new plants annually.

Repot Thunbergia alata when it becomes root-bound, typically every 1-2 years. Choose a pot that is one size larger than the current one. Use a well-draining potting mix.

Repot in spring before the active growing season commences to minimize transplant shock.
