Air Plant
Tillandsia spp. (e.g., T. ionantha, T. xerographica)
Through the year 🗓️
☀️ Summer now
Soak more often in heat and keep air moving. Stagnant humid air invites rot.
🍂 Fall
Watch for blooms and blushing on many species now; stop feeding by late fall.
❄️ Winter
Shorten soaks in cool rooms and make sure plants dry fully before nightfall.
🌱 Spring
Resume monthly feeding in the soak water and separate any pups big enough to go solo.
The details
Light & placement
- Light
- Bright indirect; silvery fuzzy species take some direct sun, smooth green ones don't
- Ideal PPFD
- 150–400 µmol·m⁻²·s⁻¹
- Grow-light distance
- 12–24 in below LED
Water & feed
- Watering method
- No soil, no pot: dunk or soak the whole plant 20–30 minutes weekly, then shake it out and dry it UPSIDE DOWN within 4 hours. Mist between soaks in dry rooms.
- Fertilizer
- Bromeliad/tillandsia feed at ¼ strength in the soak water, monthly in spring–summer.
Home & habit
- Soil
- None; it's an epiphyte, so display it on wood, in glass, or wired to almost anything. Never plant it in soil, and never seal it in a closed terrarium.
- Humidity
- Moderate to high (50%+); dry rooms mean more frequent soaks
- Temperature
- 55–85 °F
- Mature size
- 2–12 in depending on species
- Repotting
- Never; just remount or re-perch as it grows and clumps
- Propagation
- Pups form at the base after flowering; separate at ⅓–½ the parent's size or leave them to clump.
When something looks wrong
- Overwatering signs
- Base turns brown-black and soft; center leaves pull out easily, which is rot from drying too slowly
- Underwatering signs
- Leaf tips crisp and curl inward; the whole plant feels papery and light
- Common pests
- Mealybugs, scale (rare indoors)
Common problems 🩺
The usual suspects when Air Plant looks unhappy. Most houseplant trouble is watering or light, not disease — see all plant problems if you are not sure which plant is the culprit.
Base turning brown and leaves pulling away
Likely cause
Rot from water trapped at the center after soaking.
What to do
Always shake it out and dry it upside down after a soak. Never leave it sitting wet.
Curling, crispy leaf tips
Likely cause
Not enough water — misting alone rarely gets one through.
What to do
Soak it in room-temperature water for 20–30 minutes every week or two, then dry it fully.
