Air plants do not require soil and are very easy to care for. I recommend the website that I use to buy my plants as a place to download an excellent and free booklet on air plant care and their history by Jody James. The site is airplantcity.com
These plants should be submersed in room temperature water ( tap water is ok if you let it sit for 24 hours to allow the chlorine to dissapate) for at least an hour. Then place the plant upside down to drain completely ( water sitting in the base of the plant will cause it to rot. And a light misting is good once a week especially indoors. If kept outdoors in warm seasons or climates the plants take a bit less care as they will get their water and nutrients from the air. Please read the booklet for more indepth advise.
