The practice of hydrating Tillandsia, commonly known as air plants, involves providing these epiphytes with sufficient moisture to sustain their biological functions. This is achieved through methods such as soaking, misting, or submerging the plant in water. For instance, a xerographic air plant may require submersion in water for 20-60 minutes every one to two weeks, depending on environmental humidity levels.
Appropriate hydration is critical for the survival and propagation of Tillandsia. Adequate water intake facilitates photosynthesis, nutrient absorption, and overall plant health. Historically, understanding optimal watering techniques has allowed collectors and horticulturalists to cultivate diverse species of air plants outside their native tropical and subtropical environments, expanding their availability and aesthetic appeal.
