Watering Air Plants
Air plants don't have roots like other plants—they only have a few short ones which are meant to help hold it onto whatever surface it's on. In their native habitats across the Southern US, Mexico, Central and South America, air plants get what they need from high humidity and plentiful rainfall. In your home, you'll need to water your air plants about once a week—some varieties can go two weeks without being watered. Keep an eye on them to determine when your plants seems to need a drink.

To water, place them in the sink with enough water to submerge your plants. Let them soak for about half an hour, then turn them upside down on a towel to let them drain. Once they are dry, return them to their designated spot. You can also mist them every other day between baths to keep them looking fresh, especially in winter when humidity in our homes tends to be lower.

Air Plant Light Requirements
As a general rule, keep your air plants out of direct sunlight. Remember, in the wild, many air plant species like to grow up in the sheltered, shady canopy of trees. They will do best if you can put them in a brightly lit spot out of the sun's rays. A few species, such as T. cyanea or T. lindenii can handle some dappled shade or less intense morning sunlight.

Air Plant Temperature Requirements
Air plants love warm weather so it's the other end of thermometer you need to watch. Protect your plants from anything colder than 45 degrees; they will die at those temperatures.
