Air Plant problems & how to fix them
Tillandsia ionantha
Drooping, yellowing, brown tips, or a plant that just won’t thrive? Here are the most common Air Plant problems, what usually causes them, and how to turn things around.
Common problems
Root rot
Water trapped in the leaf base after soaking rots the core — the classic air-plant death. A fungal or bacterial infection of the roots, almost always triggered by soil staying wet too long. Caught early, most plants recover within a few weeks after repotting; if most roots are already mushy, recovery is uncertain.

Underwatering
Misting alone isn't enough; curled, crisping leaves mean it needs proper soaks. The plant is not getting enough water, either from infrequent watering or soil so dry it repels water. Prognosis is excellent - most underwatered plants perk up within days of proper rehydration.
Sunburn
Hot glass-magnified sun scorches patches on the leaves. Leaf tissue scorched by more direct sun than the plant was acclimated to, often after moving it to a brighter spot or outdoors. Burned patches are permanent, but the plant itself usually recovers fully once moved - new growth comes in healthy.

Cold damage
Temperatures near freezing on a winter windowsill damage the tissue. Tissue injury from a cold draft, a chilly windowsill, or a night outdoors below the plant's tolerance. Damaged leaves will not heal, but if the stems and roots survived, new growth typically appears within three to four weeks in a warm, stable spot.

The mistakes that most often kill it
- Letting water sit in the crown after soaking — rot follows within weeks.
- Relying on the occasional mist as its only water.
- Gluing it into a decoration that can never be soaked or dried properly.
