Frosty Ferns, often mistaken for true ferns, are actually a type of Selaginella kraussiana, also known as spike moss. Their delicate, frosted tips give them a festive, wintery appearance, making them a popular choice for holiday decor and year-round indoor greenery. While these plants are relatively easy to care for, they thrive best with specific attention to their humidity and watering needs. Here's how to keep your Frosty Fern lush and vibrant.
Frosty Ferns prefer bright, indirect light. Place them near a north or east facing window where they can receive filtered sunlight. Avoid direct sunlight, as it can scorch its delicate foliage. If natural light is limited, consider using a grow light to supplement their needs.
These plants love moisture and require consistent watering to keep their soil evenly damp. Water your Frosty Fern when the top layer of soil feels slightly dry, but never allow it to dry out completely. Use room-temperature water to avoid shocking the roots. Ensure the pot has proper drainage to prevent waterlogging, which can lead to root rot.
Frosty Ferns thrive in high-humidity environments. Aim for a humidity level of at least 50-70%. If your home is dry, especially during winter, use a humidifier, place a tray of water with pebbles under the plant, or mist the foliage regularly. Keeping the plant in a bathroom or kitchen, where humidity levels are naturally higher, can also be beneficial.
Plant your Frosty Fern in well-draining, moisture-retentive soil. A mix designed for tropical plants or a combination of standard potting soil with added peat moss and perlite works well. This ensures the soil retains enough moisture while allowing excess water to drain.
Frosty Ferns prefer temperatures between 60-75°F (15-24°C). They are sensitive to temperature fluctuations and do not tolerate cold drafts or extreme heat. Keep them away from air conditioning vents, heaters, or drafty windows.
Feed your Frosty Fern a diluted liquid fertilizer every 4-6 weeks during the growing season (spring and summer). Use a balanced fertilizer and avoid over-fertilizing, as this can harm the delicate roots. Reduce feeding during the fall and winter months.
Regular pruning helps maintain the shape and health of your Frosty Fern. Remove any yellowing or browning fronds to encourage new growth and keep the plant looking tidy.
Frosty Ferns grow slowly and don’t require frequent repotting. Repot them every 2-3 years or when the roots begin to outgrow the pot. Use a slightly larger container with fresh soil to give the plant more room to grow.
Frosty ferns can be propagated through plant division or stem cuttings. Division is best done in spring or early summer by gently separating the plant into smaller sections, ensuring each has healthy roots and shoots, and replanting them in moist, well-draining soil. For stem cuttings, take a 2-4 inch cutting below a leaf node during the growing season, remove the lower leaves, and plant it in moist soil or a sphagnum moss and perlite mix.
Keep the cuttings in a warm, humid environment with indirect light, covering it with a clear plastic bag or using a propagator to maintain humidity. Roots typically form within a few weeks. Propagated plants thrive in high humidity, bright indirect light, and evenly moist soil.
Frosty Ferns are considered non-toxic to pets, making them a safer choice for households with cats and dogs. However, it's always a good idea to monitor pets to ensure they don’t chew on the plant excessively.
