Air plants (Red Tilly Sky is a Tillandsia Ionantha) are supposed to be some of the easiest plants to keep alive, indoors. For starters, they don’t even need soil, absorbing water and nutrients through scales on their leaves. Once a week, dunk them in a container large enough to fully submerge them and let them sit there. For hours; it i a good practice to soak them overnight. After they soak, they need to dry out fully. Fully! Shake off any excess water and put them in a bright spot for at least 4 hours. This is key, as dampness is the main foe of an air plant. Bright filtered or indirect light is ideal for indoor air plants. Some direct sun works, too (morning is better), but they shouldn’t be baking all day. For amazing looking plants that earn you bragging rights, feed your plants once a month by adding fertilizer to the water mix. Use a bromeliad mix (air plants are in the bromeliad family), and don’t overdo it—plants can burn from too much fertilizer. Air plants are happy with a wide range of temps, from the 50s to the 90s. Just know that the hotter and drier the air, the more often you’ll have to water. Also—they’ll bite the dust in freezing temps. Air plants need air circulation. An enclosed vessel encourages wet, stagnant conditions, and this spells disaster. If you just can’t get over glass, choose a vessel with as wide a hole as possible, and be sure to let plants dry fully before you place them back inside.
