Water Cenostigma diversifolium 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 bone dry. Overwatering can lead to root rot, so ensure good drainage.

Prune Cenostigma diversifolium lightly in late winter or early spring to shape the plant and remove any dead or damaged branches. This also encourages bushier growth. Avoid heavy pruning as it can stress the plant.

Propagation of Cenostigma diversifolium is typically done through seeds sown in spring, or by semi-hardwood cuttings taken in summer. Seeds may require scarification or stratification.

Cuttings should be rooted in a well-draining medium.

Repot Cenostigma diversifolium every 2-3 years, or when the plant becomes root-bound. Use a well-draining potting mix. The best time to repot is in early spring before new growth begins.

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