How to care for your Air Plant

Everything you need to keep your Air Plant healthy: watering, light, humidity, feeding, repotting and pruning.

Tillandsia ionantha is a small epiphytic plant native to Central America and Mexico, belonging to the bromeliad family like the pineapple. Having no functional roots for absorption, it draws all its water and nutrients directly from the ambient air through the trichomes covering its leaves. Before flowering, its foliage turns a striking red, and a small violet flower emerges from the center of the rosette. Easy to care for, it can be attached to any decorative support.

Watering your Air Plant

Every 4 days

Submerge the entire plant in water for 20–30 minutes, then shake well and allow to dry upside down to prevent water pooling in the centre of the rosette. Use rainwater or demineralised water.
