Selaginella Uncinata

Selaginella uncinata, commonly referred to as the peacock fern or blue spikemoss, originates from tropical and subtropical regions, particularly in Central and South America, as well as parts of Africa and Asia. This plant is recognized for its striking, iridescent blue-green foliage, which adds a unique aesthetic to various indoor and outdoor settings.

In terms of care, Selaginella uncinata thrives in conditions that replicate its natural humid forest habitat. 

For lighting, the plant prefers bright, indirect light. Exposure to direct sunlight can scorch its delicate leaves, so it's best to place it near a north or east-facing window. If natural light is insufficient, using a fluorescent grow light can be beneficial.

Temperature and humidity are crucial for its health. Selaginella uncinata grows best in temperatures ranging from 60°F to 75°F (15°C to 24°C) and is sensitive to cold drafts. High humidity is essential, as this plant flourishes in moist environments. To maintain humidity, use a humidifier, place the pot on a humidity tray, or mist the plant regularly.

Watering should be consistent, keeping the soil moist but not soggy. It's important to water the plant when the top inch of soil feels dry, as overwatering can lead to root rot. Good drainage is essential, so ensure the pot has holes to allow excess water to escape.

For soil, a well-draining potting mix is ideal. A standard potting soil mixed with perlite or sand can enhance drainage, or a fern-specific mix may also work well.

Fertilization is not always necessary, but during the growing season (spring and summer), you can use a diluted liquid fertilizer. A balanced, water-soluble fertilizer applied at half strength every 4-6 weeks can provide additional nutrients.

Propagation can be done through division. Carefully separate a portion of the plant, ensuring that it has roots attached, and replant it in appropriate soil.

While Selaginella uncinata is generally resistant to pests, it can occasionally attract spider mites or aphids. Regular inspection and maintaining high humidity can help prevent infestations. If pests appear, treating them with insecticidal soap or neem oil can be effective.

By following these care guidelines, you can enjoy the beauty of Selaginella uncinata while ensuring its health and vitality.
