Coulteria mollis prefers consistently moist soil but can tolerate occasional dryness. Water thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, as this can lead to root rot.

Reduce watering frequency during winter months when growth slows down.

Prune Coulteria mollis to maintain its shape and size, or to remove dead, damaged, or crossing branches. The best time to prune is in late winter or early spring before new growth begins.

Light pruning can also encourage bushier growth.

Coulteria mollis can be propagated from seeds or stem cuttings. Seeds should be sown in spring after stratification. For cuttings, take semi-hardwood cuttings in summer and root them in a well-draining potting mix.

Keep cuttings moist and in a warm, humid environment.

Repot Coulteria mollis every 2-3 years, or when it becomes root-bound. Use a well-draining potting mix. Repot in spring before new growth starts.

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