How to care for Spanish Moss
Tillandsia usneoides · Bromeliaceae
Not a moss at all but a rootless, trailing air plant that hangs in silvery curtains from trees across the American South. Indoors it makes an unusual living drapery, provided you can offer bright light, real humidity, moving air, and frequent thorough wettings. Water roughly every 3 days while it's growing (about every 6 in winter), give it bright, indirect light, kept above 41°F (5°C) — it wants humid air.
Care at a glance
Mist heavily or dunk the whole strand every couple of days, ensuring it dries fully between wettings — never leave it soggy in still air.
Hang it near a bright window with good air circulation; filtered sun mimics its life in tree canopies.
Monthly quarter-strength bromeliad fertilizer sprayed on during a wetting.
Mistakes that kill this plant
- Hanging it in dry centrally heated air and misting once a week — it slowly mummifies.
- Keeping the clump constantly wet with no airflow until it rots.
- Displaying it deep in a room away from any window.
Seasonal tips
- It thrives outdoors in a shaded, humid spot in summer where rain and breeze do the work.
- Increase misting during heating season, its most dangerous time indoors.
- Fluff and separate the clump occasionally so air and water reach the inner strands.
