Watering and Fertilizing
The appearance of your air plant's leaves can give you clues about how to care for it.
Fuzzy leaves with feathery, white, silvery, and dusty coatings indicate xeric types that come from sunny, dry climates, where rainfall is less frequent. Their pronounced trichomes collect maximum water when it falls and hold it for use during dry periods. They need watering only once or twice a week and can tolerate more sun.
Smooth, glossy leaves are most common on mesic types that come from shaded, moist rain and cloud forests, where water is plentiful. They have less pronounced trichomes and less protection from drying out and hot sun. They need more frequent watering.
The best way to water your air plant depends on the plant, its location and your own preferences. Use room temperature tap or rainwater, but never softened water because the salt in it can damage your plants.
