Keep the soil consistently moist but not waterlogged, especially during active growth. Reduce watering in winter, allowing the top layer of soil to dry slightly between waterings.

Good drainage is crucial to prevent root rot. Overwatering is a common mistake.

Pruning is generally minimal. Trim away any dead or damaged foliage to maintain a tidy appearance. If the plant becomes too dense or leggy, you can shear it back lightly after flowering to encourage a more compact form.

This also helps prevent overcrowding.

Sagina caespitosa is easily propagated by division. Carefully separate small clumps of the plant during spring or early autumn. Replant the divisions immediately into moist, well-draining soil.

Alternatively, it can be propagated from seed sown in spring.

Repot young plants annually or every two years in spring to provide fresh soil and adequate space for root growth. Mature plants may require less frequent repotting, but check for root-bound conditions.

Use a well-draining potting mix and a shallow container.
