Shady Horsetail thrives in consistently moist soil. Water regularly, especially during dry spells, ensuring the substrate does not completely dry out.

Overwatering can lead to root rot, so aim for damp, not waterlogged, conditions. Frequent light watering is generally preferred.

Pruning is minimal for Shady Horsetail. Remove any dead, damaged, or yellowing stems as they appear to maintain a tidy appearance. Pinching back tips can encourage bushier growth, but is not essential.

The plant generally maintains a desirable form without significant intervention.

Shady Horsetail is best propagated by division of rhizomes in early spring. Carefully dig up the plant, separate sections of the underground stems (rhizomes) that have buds, and replant them immediately.

This method ensures true-to-type reproduction and is highly effective.

Repotting is infrequent, as Shady Horsetail prefers to be slightly pot-bound. When repotting is necessary, typically every 2-3 years, do so in early spring.

Use a well-draining potting mix and select a pot that is only slightly larger than the current one to avoid overwatering issues.
