Air plant

Tillandsia

Also known as: air plants, tillandsia, Tillandsia ionantha

Air plants (Tillandsia) are a genus of more than 600 epiphytic bromeliads that grow without soil. Their roots only anchor the plant; silvery scales on the leaves absorb water and nutrients. NC State Extension notes they need regular watering, at least once a week, and high light to flower, so the sunniest window in the home is not too much.

Care Essentials

Get to Know Your Air Plant

Watch the humidity — a little extra moisture in the air goes a long way with this plant.

Light

bright indirect

Wants bright, indirect light — sensitive to both extremes. Too much direct sun causes burns, too little causes stretching.

💡 Grow lights: Thrives under artificial grow lights (LED or fluorescent, 10-12 hours/day). A great option if your space lacks natural light.

Watering

every 7-10 days

Water when the top 1-2 inches of soil feel dry. Adjust with the seasons — less in winter, more in summer.

Humidity & Temperature

Loves higher humidity (60%+). If your air is dry, group it with other plants, use a pebble tray, or run a humidifier nearby.

Standard room temperature (60-80°F / 15-27°C) is perfect. Avoid cold drafts and sudden temperature swings.

Soil

Needs well-draining soil — add perlite or orchid bark to a standard potting mix. Good drainage is critical to prevent root rot.

Air Plant Dehydration: Curled Leaves and How to Rehydrate

Curled or rolled leaves are the main sign of a dehydrated air plant. Air plants take up water through scales on their leaves, not their roots, so occasional light misting in dry indoor air often leaves them short of water.
