Maerua arenaria prefers infrequent watering, allowing the soil to dry out completely between waterings. Overwatering can lead to root rot, especially in poorly draining conditions.

Reduce watering significantly during its dormant period in cooler months to prevent waterlogged roots and promote plant health.

Pruning Maerua arenaria is primarily for shape and to remove any dead or damaged branches. Minimal pruning is usually required.

If you need to control its size or encourage bushier growth, prune in early spring before new growth begins. Use clean, sharp tools to make precise cuts.

Propagation is typically achieved through seeds, which may require stratification or scarification to enhance germination. Cuttings can also be attempted, but success rates can be variable.

Take cuttings from healthy, mature stems in spring or early summer and use rooting hormone.

Maerua arenaria benefits from repotting when it becomes root-bound, typically every 2-3 years. Use a well-draining potting mix, such as a cactus or succulent blend. Repot in spring, just as new growth appears.

Handle the roots gently to avoid unnecessary damage.
