Mosser Lee Sphagnum Moss and Indoor Dormancy for Temperate Plants

Dried Moss Rarely Regrows Live

A Zone 8 grower asks if Mosser Lee long-fibered sphagnum moss can revive, and how to induce dormancy in VFTs and Sarracenia indoors with 4 hours direct sun + 10 hours artificial light.

Moss Regrowth Is Rare Luck

Mosser Lee is excellent (we use it), but dried moss rarely contains viable spores. Occasional fresh batches with green bits may regrow, but it’s the exception.

Indoor Dormancy Is Extremely Difficult

Temperate plants need cold temperatures and shortening days to trigger dormancy—homes are too warm. We grow all North American plants outdoors in zone 8; nights in the 40s naturally induce dormancy. Move plants outside now (before first frost) to acclimate. They’ll go dormant after frosts and can stay out. See care sheets and videos: caresheets | videos.

Good growing!
