What are Tillandsia airplants
Tillandsia (airplant, aerial plants, epiphytic plants) refers to hundreds of epiphytic species and selections—over 500 varieties in the genus—that can live without potted substrate. These plants absorb water and some nutrients through their leaves—in nature, from rainwater running down tree trunks, for example. The roots, when present, mainly serve to anchor the plant to wood, stone, or other supports and do not absorb “nutrients from substrate” like traditional potted plants.
They are easy to grow if you follow three key ideas: good filtered light, watering with complete drainage, and drying after watering. Do not keep them permanently wet or enclosed damp in airtight globes/containers without air circulation.

Cultivation highlights
The watering frequency, misting, and exposure below are approximate guidelines. Species with silvery (more “xeric”), tougher leaves tolerate dry air and infrequent watering better; greener and more delicate ones require water more often. Plant size, room temperature, and dry air from radiators affect the actual growth rhythm.
Placement and light
For active growth and chances of flowering, place airplants in a well-lit spot with filtered light. Strong direct sun, especially afternoon sun, can quickly burn the leaves—and even more, can dehydrate and dry out the plant completely in a short time.
Keep specimens away from radiators in winter and air conditioning drafts in summer. Very hot and dry air or cold drafts stress the plant more than a stable, slightly imperfect temperature.
You can mount Tillandsia on wood, cork, stone, or open supports. If you place it in a glass bowl, choose one with ventilation holes and remove the plant when you want to water it—do not let it sit in water at the bottom of the container.
Watering and drying
Do not pour water “like for potted plants” over a plant on a support without draining the water from between the leaves afterward.
Practical method: once a week (approximately), run the plant under lukewarm water or briefly submerge it in room temperature water. Let the water drain well. Turn the plant upside down with leaves down for a few minutes if it retains water in the rosette. When the leaf surfaces are completely dry, put it back in place.
If leaves remain wet for hours in poorly ventilated air, the risk of rot at the base increases. Drying after watering is as important as watering itself.
In very dry rooms or heat, you can water a bit more often. In cool rooms, reduce watering frequency. Watch the plant: very wrinkled leaves over time indicate it needs more water; a soft, darkened base signals excess.
Misting and feeding
Misting complements but does not always replace weekly watering. On hot days, you can mist 1-2 times a week; in cooler periods, once every 1-2 weeks is often sufficient.
If you use nutritive spray for tillandsia / very diluted foliar fertilizer for orchids, apply it to a wet plant or after light watering, not on dry leaves. Excess salts leave marks and can burn leaf tips.
Ongoing maintenance
As the plant grows, the lower leaves may dry out. This is normal. You can remove them when they come off easily; if they resist, wait a few days and try again to avoid tearing live tissue.
After flowering, many Tillandsia produce pups at the base. The mother plant may gradually decline after flowering; pups continue growing if you let them develop enough before detaching.
Common problems
- Soft base, unpleasant smell – water trapped in the rosette or too slow drying after watering. Drain the plant well and improve ventilation.
- Burned/dry leaves, brown spots on exposed side – too strong direct sun. Move the plant to filtered light.
- Very wrinkled leaves, hard to rehydrate – watering too infrequent. Increase watering frequency without leaving the plant permanently wet.
- No growth at all – low light or plant kept always wet/cold. Check light and drying after watering first.
Frequently asked questions
Do they need soil?
No, not in the classic sense. Most airplants are grown on supports without potted substrate. Some ground-growing Tillandsia species are exceptions; those sold as airplants are generally epiphytic.
Can I grow them only by misting, without soaking?
For some small species, yes, if you mist often and the air is not very dry. For most commercial mixes, a thorough weekly watering plus complete drying is safer.
Why do they rot in a glass globe?
Because water and moisture remain trapped without sufficient ventilation. Remove the plant at watering time, drain it, dry it, then put it back.
