Growing air plants (Tillandsia) outside is definitely possible and can be quite rewarding! Here's how to successfully cultivate these unique plants in an outdoor environment:
1. Location, Location, Location!
- Bright, Indirect Light: Air plants thrive in bright light but avoid direct, harsh sunlight, especially during the hottest parts of the day. Prolonged exposure can scorch their leaves. Think of a location that receives filtered sunlight or is shaded during the afternoon.
- Part-Shade Option: If your only option is a location with direct sunlight, aim for part-shade where the air plant is protected from the intense late-day sun.
- Avoid Dark Corners: While they don't need full sun, air plants still need light to photosynthesize. A dark, gloomy area won't cut it.
2. Watering and Humidity
- Monitor Natural Rainfall: If you live in an area with frequent rain and high humidity, you may not need to water your air plants as often. Observe the plants; if they appear healthy and green, nature is likely taking care of them.
- Watering Schedule: If natural rainfall is infrequent, mimic indoor watering:
- Soaking: Soak the air plants in a bowl of water for 20-30 minutes every 1-2 weeks.
- Misting: Mist them with water 2-3 times per week, especially during dry periods.
- Air Circulation is Key: After watering, ensure the air plants dry completely within 4 hours. Avoid letting water sit in the crevices of the plant, as this can lead to rot. A well-ventilated location is crucial.
3. Fertilizing
- Occasional Feeding: Fertilize your air plants sparingly, about once a month during the growing season (spring and summer).
- Use a Bromeliad Fertilizer: Dilute a bromeliad fertilizer to 1/4 strength and add it to the water when soaking or misting. Avoid fertilizers with copper, as it's toxic to air plants.
4. Mounting and Display
- Secure Attachment: You can mount air plants on various surfaces like wood, rocks, or shells using non-toxic glue (like E6000) or wire. Ensure the plant is securely attached but not suffocated.
- Creative Displays: Consider hanging them in macrame planters, attaching them to driftwood, or creating a vertical garden.
5. Cold Weather Considerations
- Bring Them Inside: Air plants are sensitive to frost and freezing temperatures. If you live in an area with cold winters, bring your air plants indoors before the first frost.
By following these guidelines, you can successfully grow air plants outside and enjoy their unique beauty in your outdoor space.
