Prof. Charles Hartman, Ph.D.In climates suited to it, keeping air plants outside can be favorable while requiring some considerations. Air plants can be grown outdoors because they are suited for USDA zones 9-11, provided they are in a suitable location and given some protection. When air plants are grown outside, they grow much faster; however, the risk from environmental factors is also higher. Whether you should keep your air plants outside depends on your location and your awareness of seasonal changes.
Placement Strategies
- Hang under tree canopies for filtered sunlight
- Position on covered porches avoiding direct rain
- Elevate displays to prevent ground pests
- Ensure protection from strong winds
Weather Protection
- Bring indoors when temperatures drop below 50°F
- Shelter during heavy rain to prevent oversaturation
- Shade from intense midday summer sun
- Cover during hail or extreme weather events
Seasonal Transitions
- Acclimate plants gradually over 7-10 days
- Increase watering during hot summer months
- Reduce hydration as temperatures cool in fall
- Discontinue fertilizing before winter dormancy
Take advantage of outdoor perks, such as faster growth and the benefits of insect and animal pollination. Additionally, the increased airflow helps prevent fungal-related issues. Natural rainfall can help supplement your watering schedule, with the morning dew adding another layer of moisture that benefits your plants. Lastly, my outdoor plants bloomed more abundantly than my indoor plants.
To maintain safe outdoor plants, you should implement pest prevention.Check frequently for pest insects such as aphids and mealybugs, and gently spray your plants with water to dislodge insects from leaves, stems, and any bird nests. Please do not use chemical pesticides, as they can destroy trichomes. Before adding new plants with trichomes to your outdoor collection, quarantine them indoors for a few days to ensure they are free from pests.
Alter watering practices depending on outdoor conditions. Extend the frequency of soaking during hot, dry periods. Reduce watering when the humidity level is greater than 60%. Use rainwater whenever possible. Always allow for complete drying in 4 hours or less to prevent rot in humid climates.
Anticipate seasonal changes between the outdoor and indoor environments. Each spring, slowly acclimate the plants for a period of 10-14 days. Each fall, check the plants for pests before bringing them indoors. Each spring and fall, allow for gradual adjustments to lighting to reduce potential shock. These cultural practices will help keep the plants healthy throughout the entire year.
