Allow soil to dry out between waterings. Santolina canescens is drought-tolerant and prone to root rot if overwatered. Water thoroughly when the top 5-7 cm of soil feels dry.

Reduce watering significantly during winter dormancy.

Prune after flowering to maintain a compact shape and encourage bushier growth. Cut back stems by about one-third to prevent woody, straggly stems. Regular light trims will keep the plant tidy and promote denser foliage.

Easily propagated from softwood cuttings taken in late spring or semi-hardwood cuttings in late summer. Root cuttings in a well-draining potting mix.

Alternatively, sow seeds in spring, though cuttings often yield faster results.

Repot only when necessary, typically every 2-3 years, in spring. Choose a pot only slightly larger than the current one, ensuring excellent drainage. Use a gritty, well-draining compost mix to prevent waterlogging.
