Water Asteranthera ovata moderately during the growing season, allowing the soil to dry slightly between waterings.

Reduce watering significantly in winter, providing just enough to prevent the soil from becoming completely dry. Ensure good drainage to avoid waterlogging, which can lead to root rot.

Prune Asteranthera ovata lightly after flowering to maintain shape and encourage bushier growth. Remove any dead or damaged stems at any time. Pinching back young shoots can also promote a more compact form.

Avoid heavy pruning, as it may reduce flowering.

Propagate Asteranthera ovata from semi-hardwood cuttings taken in late summer or early autumn.

Insert the cuttings into a well-draining rooting medium and keep them in a warm, humid environment with bright, indirect light. Rooting typically takes several weeks.

Repot Asteranthera ovata every 2-3 years in spring, or when the plant becomes root-bound. Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost.

Choose a pot that is only slightly larger than the current one to avoid overwatering.
