Tillandsias are very hardy and require much less attention than other house plants. Provided the atmosphere is not too dry they can survive with water misting and the occasional bath. Give them bright, filtered light, and protect them from frosts. If you are growing them indoors and the air is dry, you will need (at minimum) to submerge the plant in water for 2-3 hours about every two weeks. 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.
Since air plants do not require soil to grow, they can be mounted to almost any surface for display. Use the base of the plant as the mounting area. Adhesives like E-6000, Liquid Nails, or Goop work great, as well as fishing line or any non-copper wire. When choosing a mounting surface remember that your plant will still need to be watered, so something waterproof or water-resistant will be the best choice for a long-term display.
