Thunbergia affinis prefers consistently moist soil, especially during its active growing season. Water thoroughly when the top 2-3 cm of soil feels dry to the touch.

Reduce watering slightly in cooler months or when the plant is dormant, but avoid letting the soil become completely parched.

Prune Thunbergia affinis to maintain its shape and encourage bushier growth. Pinch back the tips of new stems to promote branching. Remove any dead, damaged, or leggy stems at any time of year.

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

Thunbergia affinis can be propagated from stem cuttings taken in spring or summer. Select healthy, non-flowering shoots, cut them to about 10-15 cm, and remove lower leaves.

Dip the cut end in rooting hormone and insert into a moist, well-draining potting mix. Keep in a warm, humid environment.

Repot Thunbergia affinis every 1-2 years or when it becomes root-bound. The best time for repotting is in spring, just as new growth starts.

Use a slightly larger pot with good drainage and a fresh, well-draining potting mix. Water thoroughly after repotting.
