Air plants, or Tillandsia, are bromeliads that originate primarily in Central America. A few species, like Spanish moss, are much more widespread. They grow mostly in trees above the ground. Some air plants have roots, but they only use these to anchor themselves in place. Water and nutrients are absorbed through the body of the plant itself.
Air plants grow best in bright filtered light. Both natural and artificial light work well, but they will not thrive in low light.
When kept indoors, air plants definitely need to be watered. It’s best to use filtered or distilled water; tap water can be hard on them and hard water can cause mineral deposits over time. Although many people mist their air plants several times a week, we recommend that you soak your air plant for about 30 minutes weekly. Afterwards, shake the excess water off your plant and place in a spot with good air movement. Air plants should be dry within four hours of watering.
Feeding y our air plants is important to long term success. Air plants are very slow growing, but they can flower and offset. Feeding them helps greatly with this process. Make sure to use a plant food formulated for air plants, as they don’t have a typical root system to help break down nutrients.
