Water thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, as Drymaria arenarioides prefers well-draining soil and can be susceptible to root rot.

Reduce watering frequency during cooler months or when the plant is dormant. Ensure good drainage to prevent waterlogged conditions.

Prune lightly after flowering to maintain a tidy shape and encourage bushier growth. Remove any dead or leggy stems to improve air circulation and overall plant health.

Pinching back the tips of young plants can promote a more compact habit. Pruning is generally minimal for this species.

Easily propagated from stem cuttings taken in spring or summer. Insert cuttings into a well-draining potting mix and keep them moist. Alternatively, seeds can be sown in spring. Germination may be slow and erratic.

Division of established clumps is also a viable method in spring.

Repot every 2-3 years or when the plant becomes root-bound. Use a well-draining potting mix, such as a cactus or succulent blend. Choose a pot only slightly larger than the current one.

Spring is the ideal time for repotting to allow the plant to establish before the growing season. Ensure good drainage holes.
