- Grow Thunbergia in rich soils to help fuel growth. Prior to planting, mix in ample amounts of compost.

- Keep the soil well-watered, especially when young, and during hot and dry weather. If grown in containers, be vigilant that they do not dry out.
- Keep young plants well weeded, until they get established and begin to climb. Thunbergia plants can be trimmed, as needed.
