Air Plants, or also known as Tillandsia, should be watered 2-3 times a month. In a hot and dry environment, it may be watered more often and less often in a cool humid one. A common rule of thumb is to water it once a week in more hot climates.
Spray misting is not sufficient in watering but will help in between waterings in the more hot conditions.
For best results, place the plants in a bowl of water to cover a partial amount of the plant for up to 10 minutes.
Tillandsia plants should not be left in standing water, so you should blot the plants with tissue paper or cloth after watering. Don’t forget to get rid of water in the base of the leaves! Rot will occur if too much water is left standing in the base.
Tillandsias need bright but not direct sunlight for long periods of time during the summer. From November to March they can thrive with direct sunlight.
Artificial light can work if you use full spectrum (fluorescent) light, although I prefer letting them thrive in a bright window.
Things You Will Need:
Bowl or plastic container as deep as air plant
Rock or brick
70 percent isopropyl rubbing alcohol
Submerge the air plant in the container’s lukewarm water. Tie the plant loosely to a rock or brick by using string if doing so is necessary to weight the plant and prevent it from floating to the water’s surface. Pour additional water into the container if it is needed to cover the entire plant with water
Move the container to a room with a constant temperature of 65 to 75 degrees Fahrenheit. Position the container in bright, indirect sunlight on a flat surface where it will remain undisturbed. Let the air plant soak in the container for 12 hours.
Remove the air plant from the water. Cut the string holding it to the rock or brick if applicable. Swing the plant gently back and forth with your hand to shake excess water from the leaves. Place the plant on a paper towel, and let it air-dry. Return the plant to its original growing site.
Check the air plant for signs of leaf curling two or three days after you soaked it in water. Submerge the air plant in water again in the same manner as before if it sports curling foliage, and let the plant soak in the water for four hours. Shake the plant gently to remove excess water. Place the plant on a paper towel, and allow it to air-dry.
