Ipomoea triloba prefers consistently moist soil. Water thoroughly when the top 2-3 cm of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot.

During hot, dry periods, more frequent watering may be necessary to maintain optimal moisture levels.

Prune Ipomoea triloba to manage its size and shape, and to encourage bushier growth and more blooms. Remove dead, damaged, or leggy stems. Pinch back the tips of young plants to promote branching.

Pruning can be done after flowering to maintain tidiness.

Ipomoea triloba can be easily propagated from seeds. Sow seeds indoors 4-6 weeks before the last frost or directly outdoors after the danger of frost has passed. Scarify or soak seeds to improve germination rates.

Cuttings can also be taken from healthy stems in spring or summer.

Repot Ipomoea triloba annually or biennially in spring, or when it becomes root-bound. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix.

Ensure the new pot has drainage holes to prevent waterlogging, which can harm the roots.
