Watering, pruning, propagation, and repotting details from plant data
Giant chain fern thrives in consistently moist soil. Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, which can lead to root rot.
In drier conditions, misting or a pebble tray can help maintain adequate humidity around the plant, especially during warmer months.
Prune out any dead, damaged, or discolored fronds at their base to maintain the plant's health and appearance. This can be done at any time of year as needed.
Removing old fronds also encourages new growth and helps prevent fungal diseases.
Giant chain fern is best propagated by division. In spring, carefully divide established plants into smaller sections, ensuring each division has roots and at least one frond.
Replant the divisions immediately into moist soil and maintain consistent moisture until new growth appears.
Repot young plants annually or when they become root-bound, typically in spring. Use a well-draining, peat-based potting mix. Mature plants can be repotted every 2-3 years.
Choose a pot only slightly larger than the current one to avoid excessive moisture retention.
