Keep the soil consistently moist but not waterlogged. Isolepis aucklandica thrives in damp conditions, similar to its natural wetland habitat. Water thoroughly when the top centimeter of soil begins to feel dry.

Avoid letting the plant dry out completely, as this can stress it.

Pruning is minimal for Isolepis aucklandica. Remove any dead, yellowed, or unsightly foliage as needed to maintain a tidy appearance.

If the plant becomes too dense or overgrown, you can lightly trim it back to encourage bushier growth and improve air circulation.

Propagation is best done by division of established clumps in spring. Carefully separate the root ball into smaller sections, ensuring each section has roots and shoots.

Replant the divisions immediately into well-draining, moist potting mix. Alternatively, seeds can be sown in spring.

Repot Isolepis aucklandica every 1-2 years, or when it becomes root-bound. Choose a pot that is only slightly larger than the current one. Use a well-draining potting mix, ideally one with added organic matter.

Ensure the new pot has adequate drainage holes to prevent waterlogging.
