Tillandsias grow differently from most house plants, so they can be confusing to the beginner, but they are very hardy, and require a lot less care than most house plants.
1. Provided the atmosphere is not too dry they can survive with water misting and the occasional bath.
2. Never plant in soil. Give them bright, filtered light.
3. Protect them from frosts. If you are growing them indoors and the air is dry, you will need to submerge the plant in water for 2-3 hours every two weeks.
4. In a shaded-house or unheated home, you can use a soaking mist once or twice a week in summer, once a month in cooler weather.
5. You can fertilize by adding a pinch of Bromeliad or Orchid fertilizer to your mister.
Thoroughly wet your Tillandsia 2-3 times per week; more often in a hot, dry environment; less often in a cool, humid one. Tillandsia cannot get water from their roots like a terrestrial plant, or draw on internal reserves like a succulent. You may notice that your new air plants appear to be fuzzy. These are trichomes, a coating of special cells which helps air plants absorb water and nutrients.
