Spike Moss likes humid environments and thrives with consistent moisture. They grow easily in humid environments and is overall easy to care for.
Light: Bright but indirect light should be used indoors; partial shade outdoors is usually a good idea for most Selaginella Plants.
Water: Keep the soil of a Selaginella Plant moist but never soggy and avoid using cold water. A Selaginella Plant becomes totally dormant and the leaves roll into tight little brown balls when there is no moisture. Once the Selaginella Plant is watered, it turns green and starts to grow again.
Temperatures: Best temperature for a Selaginella Plant is 50-75 (F) degrees (10-24 C). Some types of Selagenella Plants can handle temperatures as low as 40 degrees.
