The Ultimate Guide to Caring for Air Plants
Everything you need to know about these fascinating epiphytes – from watering to displaying and troubleshooting
Introduction to Air Plants
What are Air Plants?
Air plants (Tillandsia) are unique epiphytes that don’t require soil to grow. In their natural habitat, they attach themselves to trees, rocks, or shrubs, absorbing nutrients and moisture from the air through specialized structures called trichomes.
Why They’re Popular
Air plants have become increasingly popular houseplants because they’re:
- Low maintenance and versatile
- Perfect for small spaces and apartment living
- Available in a variety of shapes, sizes, and textures
- Can be displayed in creative ways since they don’t need soil
- Many varieties produce colorful blooms
Important to Remember:
Never plant air plants in soil! They’re epiphytes, which means they grow attached to other plants in nature and get their nutrients from the air and water around them.

Soaking air plants in a bowl of water is the most effective watering method
The Soaking Method
The most effective way to water air plants is by soaking them thoroughly. Here’s how:
Weekly Soak: Submerge your air plants completely in water for 20-30 minutes once a week.
Shake Off Excess: After soaking, gently shake the plants to remove excess water from between the leaves and base.
Dry Thoroughly: Place plants upside down on a towel in a bright area with good air circulation. They should be completely dry within 1-3 hours.
Pro Tip:
Adjust your watering schedule based on your climate. In hot, dry environments, soak more frequently or add misting between soakings. In humid environments, you may need to water less frequently.
Water Type Matters
- Best choices: Rainwater, aquarium water, or filtered water
- Acceptable: Tap water that has sat for 24 hours (to allow chlorine to dissipate)
- Avoid: Distilled water (lacks minerals) and softened water (too salty)
Warning:
Never let air plants sit in standing water! Always ensure they dry completely after watering to prevent rot.
Light Requirements
Finding the Perfect Light
Air plants thrive in bright, indirect light. Here’s what you need to know:
| Light Type | Suitability | Notes |
|---|---|---|
| Bright indirect light | Excellent ✓✓ | Ideal placement: Near east or north-facing windows |
| Filtered sunlight | Good ✓ | Through a sheer curtain or nearby a window |
| Direct sunlight | Avoid ✗ | Can burn leaves, especially afternoon western exposure |
| Low light | Poor ✗ | Plants will survive but not thrive; growth slows significantly |
| Artificial light | Acceptable ✓ | Full-spectrum fluorescent lighting within 36″ of plants |
Placement Suggestions:
- East-facing windows provide gentle morning light
- North-facing windows work well in summer
- South-facing windows with sheer curtains provide filtered light
- Rotate plants occasionally for even exposure
- Keep 1-3 feet away from full-spectrum artificial lights

Air Circulation
The Importance of Good Air Flow
Despite their name, air plants don’t just need air to survive—they need good air circulation. Proper airflow helps prevent moisture-related issues and ensures plants can effectively absorb nutrients.
Do’s
- Ensure plants dry completely within 1-3 hours after watering
- Place in areas with natural air movement
- Use open containers or displays that allow airflow
- If using terrariums, choose ones with large openings
- Occasionally relocate plants to refresh air exposure
Don’ts
- Avoid completely enclosed containers
- Don’t surround plants with moss (holds too much moisture)
- Avoid placing in stagnant air areas
- Don’t place wet plants in areas without airflow
- Avoid exposing to strong, continuous drafts that dry plants too quickly
Important Note:
Air plants in glass containers require extra attention. After watering, ensure they dry completely before returning them to their container, and periodically remove them to receive fresh air circulation.
Temperature & Environment
Creating the Right Climate
Air plants are native to tropical and subtropical regions, so they prefer warm temperatures and moderate humidity. Understanding their environmental needs is key to success.
Temperature Range
- Optimal temperature range: 50-90°F (10-32°C)
- Preferred range: 60-80°F (15-27°C)
- Can tolerate brief periods of: 40-95°F (4-35°C)
- Cannot tolerate: Frost or freezing temperatures
Humidity Considerations
Air plants appreciate moderate humidity levels of 40-60%. Indoor environments, particularly in winter with heating systems, often have lower humidity than air plants prefer.
Tips for Increasing Humidity:
- Group plants together to create a microclimate
- Place in naturally humid areas like kitchens or bathrooms
- Use humidity trays (water-filled trays with pebbles)
- Mist plants more frequently in dry environments
Seasonal Adjustments
Air plants may need different care depending on the season. In winter, when indoor air is drier and ambient light is lower, you may need to:
- Increase misting frequency
- Move plants closer to light sources
- Protect from cold drafts and heating vents

Mounting & Attaching Air Plants
Recommended Methods:
- E-6000 glue – Waterproof and non-toxic when dry
- Hot glue – Allow to cool for 5 seconds before attaching plant
- Fishing line or thread – Invisible attachment method
- Floral wire (non-copper) – Good for temporary displays
Avoid These Methods:
- Copper wire – Toxic to air plants
- Super glue – Can damage plant tissue
- Nails/staples through fleshy parts – Use only on woody stolons
- Completely enclosing in moss or other material
Growth Cycle & Reproduction
Understanding the Air Plant Life Cycle
Air plants have a unique life cycle that differs from most houseplants. Each plant will bloom once in its lifetime, then produce offsets (pups) before eventually dying.
Young offset growing from mother plant
3-5 years of vegetative growth
Produces flowers (once in lifecycle)
Produces 2-8 offspring
Mother plant gradually dies
Flowering Process
Most air plants bloom at some point between winter and summer. The blooming process begins with a bloom spike (inflorescence) emerging from the center of the plant. Flowers can last from days to months depending on the species. While beautiful, the blooming process signals that the plant is reaching the end of its lifecycle.
Propagating Air Plants
The main method of propagation is through pups (offsets). After blooming, most air plants will produce 2-8 pups from their base.
How to Separate Pups:
- Wait until the pup is at least 1/3 to 1/2 the size of the mother plant
- Hold both the mother and pup at their bases
- Gently twist in a downward motion to separate
- If resistance is felt, use clean scissors to cut as close to the mother plant as possible
- Care for the pups as you would adult plants, but they may need slightly more frequent misting
Note: Don’t discard the mother plant after it produces pups! As long as it still has healthy leaves, it may continue to produce more pups over several years.
