🌱 How to Care for Air Plant to Prevent Fungus Gnats?

💧 How to Water

Submerge the air plant completely in room-temperature water for 20-30 minutes every 10-14 days. After soaking, gently shake off excess water and place upside down on a towel or rack to dry completely within 4 hours. Standing water trapped between leaves is the primary cause of rot. In very dry environments, mist 2-3 times per week as a supplement between soakings.

☀️ Lighting

Place your air plant in a spot with bright, indirect light such as an east or west-facing window. Xeric varieties (fuzzy, grey-leafed types) can tolerate some direct morning sun, while mesic varieties (smoother, green-leafed types) prefer partial shade. Avoid harsh midday direct sunlight which can scorch leaves.

🪴 Ideal Soil

No growing medium required. Mount on cork bark, driftwood, volcanic rock, or place in decorative holders. Avoid closed containers or terrariums without ventilation that prevent proper drying after watering.
