Looking for the lowest-maintenance plant? Tillandsia, or "air plants" require only light and water.
Air plants can be placed in aeriums (soil-less terrariums) for greater humidity so you don't have to mist or water them as often.
During Winter, place air plants in direct morning or afternoon sun to improve their appearance.
Dunk air plants in water for a few minutes two or three times a week to help their health.
Fertilize air plants with water-soluble fertilizer for houseplants or orchids monthly or every other month.
