Hemigraphis sumatrensis prefers consistently moist soil. Water thoroughly when the top inch of soil feels dry. Avoid waterlogged conditions, which can lead to root rot.

Reduce watering slightly during cooler months, but do not allow the soil to dry out completely.

Prune Hemigraphis sumatrensis to maintain its shape and encourage bushier growth. Pinch back leggy stems to promote branching. Remove any yellowing or dead leaves promptly to keep the plant healthy and attractive.

Pruning can be done anytime growth seems excessive.

Propagation is easily achieved through stem cuttings. Take 4-6 inch cuttings from healthy stems, remove the lower leaves, and place them in moist potting mix or water.

Roots typically form within a few weeks, after which they can be transplanted.

Repot Hemigraphis sumatrensis every 1-2 years, or when it becomes root-bound. Choose a pot that is only slightly larger than the current one. Use a well-draining potting mix.

Repotting is best done in spring, coinciding with the start of active growth.
