Selaginella is a moisture-loving plant and needs constant moisture to stay fresh and healthy. It prefers semi-shady to shady locations with well-drained, humus-rich soil. Regular watering is crucial, but waterlogging should be avoided as this can lead to root rot. High humidity is also beneficial, especially indoors. Outdoors, the plant should be protected from strong winds. The exact care requirements can vary depending on the Selaginella species, so it is advisable to check for a specific species for its individual needs.
