How to prune spike moss

Spring and summer during active growth; trim at any time to control spread. Use clean scissors to cut back spreading stems to the edge of the desired area. For dead patches in the centre, remove brown material and improve humidity and moisture — bare patches often re-colonise from surrounding growth. Avoid letting it dry out, as dry conditions cause rapid browning.

As needed — light trimming every few months to control spread. Spike Moss (Selaginella kraussiana) needs minimal pruning. Trim back stems that have crept too far beyond their intended area or are dying back at the centre. It spreads rapidly as a ground cover and occasional light trimming keeps it contained. Remove any brown or dead patches to encourage the mat to fill in with fresh green growth.
