Handling Instructions

Shipped Live: Fern Moss is shipped live and fully hydrated. It can be planted right after delivery.
Storage: If not planted after delivery, you can store it in a container with some airflow in a cool and shaded location. Mist it daily, but don’t overdo it. Usage: Plant this moss straight onto the substrate. Use a biodegradable mesh for vertical surfaces or pin it down. Gently push it down to remove air pockets, mist when it feels dry until it is properly established.

Ecological and Ethical Harvesting

As with all our live mosses, our Thuidium delicatulum is sustainably hand-harvested. Only 30% of the population is harvested to allow regrowth. We ensure minimal disturbance to flora and fauna.
