Water Psephellus andinus thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, which can lead to root rot. Reduce watering during winter dormancy. Ensure good drainage to prevent waterlogged conditions.

Prune Psephellus andinus after flowering to maintain its shape and encourage bushier growth. Remove any dead, damaged, or leggy stems. Light pruning can be done at any time to improve air circulation and appearance.

Propagate Psephellus andinus from seed sown in spring or by taking stem cuttings in late spring or early summer. Cuttings should be treated with rooting hormone and planted in a well-draining medium.

Seeds may require stratification.

Repot Psephellus andinus every 2-3 years in spring, or when the plant becomes root-bound. Use a well-draining potting mix.

Choose a pot that is only slightly larger than the current one to avoid excessive soil moisture retention.
