Selaginella thrives in high-humidity environments, making it an excellent choice for terrariums or shaded areas with consistent moisture. To enhance humidity around the plant, place it on a tray of water with pebbles or group it with other moisture-loving plants. Avoid exposure to direct sunlight, which can scorch the delicate foliage, and prune any brown or dried leaves to encourage lush, vibrant growth.

Selaginella requires regular watering to maintain its moisture-loving nature. Keep the soil consistently damp but not waterlogged, as excessive water can lead to root rot. Water deeply during dry periods or when grown indoors, ensuring even hydration. Misting the foliage regularly can also help maintain the high humidity levels Selaginella prefers. Always water early in the morning or late in the evening to minimise evaporation and ensure the plant absorbs moisture effectively.

To plant Selaginella, choose a location with moist, well-draining soil enriched with organic matter. These plants thrive in partial to full shade, making them ideal for shaded garden areas or terrariums. Prepare the soil by mixing in compost or peat to retain moisture, and dig a hole just large enough to accommodate the root ball. Position the plant carefully, ensuring the crown is at soil level, then backfill gently. Water thoroughly after planting and keep the soil consistently moist to promote healthy establishment.
