Care of Air Plants
Tillandsia and other types of bromeliads are known as air plants. This means that they are able to grow and thrive without soil. Air plants absorb the nutrients they need by means of their leaves rather than their roots, the way most plants do. Even though you do not need to plant an air plant in potting soil, they do need care and attention including adequate water, appropriate lighting and even fertilization in order to flourish.
Give your air plant plenty of water. Soak the air plant in a water-filled sink or container for two to three minutes. Turn the air plant upside down and shake it gently to drain off excess water. Mist your air plant using a spray bottle two or three times a week, as well.
Place or hang your air plant in a location that allows for adequate circulation, especially after watering. Standing water or too much moisture will damage the plant.
Provide ample indirect sunlight to your air plant, if possible. These plants love the sun but are prone to sunburn, as well. Hang or place an indoor air plant within three feet of a sunny window. Outdoor plants will do well on a porch or patio that partially shades them from direct sunlight.
Prevent air plants from extreme temperatures. Air plants are tropical and can withstand temperatures in the high 80's. Freezing temps, though, can harm an air plant, as can severely hot weather. If you keep your air plant outdoors, consider moving it inside during cold winter or scorching summer weather.
Fertilize your air plant in order to encourage blooms. Most varieties of air plants will produce dazzling flowers in tropical pinks, purples and oranges when fertilized. Once or twice a month, add special bromeliad fertilizer to your air plant's water.
Air plants: They're one of those things you've heard people mention, but if someone asked you about them, you'd be like, "They are plants, that, uh... float in the air?" They’re epiphytes, meaning they don’t need soil to grow and are natively found clinging to tree branches in the southern states of the U.S. down through Central America and South America. Because They're mostly found in tropical climates, it's important to make sure your air plant is warm enough. The general rule is if you need a sweater, your air plant is cold and needs to be moved into more sun. It shouldn't need watering for two weeks. You might be thinking, Won't that lead to over watering? Keep an eye on the shape and color of the leaves of your plant. If you notice the leaves are curling under or turning brown, shorten your watering schedule to every 10 days instead of every two weeks, and so on, until you find the right amount. One popular way to display them is to place them in 3-D geometric shapes (like the photo above).
