Tillandsia (Air Plant)
Tillandsia spp.
Epiphytic bromeliads that grow without soil, taking moisture and nutrients through leaf trichomes. Mount them or set them in open displays with bright filtered light, weekly soaks, and full drying afterward so the crown never stays wet.

Full care guide
Tillandsia Care
Grow Tillandsia (air plants) with bright indirect light, a weekly soak, a full dry-down, and free airflow so trichomes can drink without rotting the base.

Full guide →Light
Bright, filtered light keeps plants firm. Direct afternoon sun can dehydrate and burn leaves. Strong airflow matters; skip sealed terrariums unless you can ventilate.
Water
Soak in room-temperature water for 20-30 minutes about once a week. Shake off excess, then dry upside down on a towel with good air movement so the plant is fully dry within about 4 hours. Trapped water in the crown causes rot.
Soil
Do not pot in regular soil. Mount on wood, wire, or an open display. Traditional potting mix will rot the plant.
Humidity & Temperature
Higher humidity helps between soaks. Keep temperatures around 50-90°F and away from frost and drafty winter windows.
Common Issues
Brown crispy tips usually mean underwatering or dry air. A black or soggy base means rot from trapped water; remove soft parts and dry more thoroughly after soaks.

Fertilizer
Bromeliad or Air Plant specific liquid fertilizer (low-copper)
