A Beginner's Guide to Watering Air Plants
Air plants look effortless.They require no soil, have minimal setup, and seem to survive on just air. However, most air plants die due to improper watering, not neglect, but doing it the wrong way. The good news is that watering air plants isn't complicated. Follow our guide to learn how.
How Often to Water Air Plants
Most air plants prefer a thorough soak once or twice a week, depending on the temperature and humidity of your environment. Generally, drier air requires more frequent watering than humid air.
You can tell if your air plants are dehydrated by observing their leaves. When they are too dry, the leaves may curl inward or become more tubular. Some thinner-leaved varieties, such as Tillandsia tenuifolia, tend to show signs of dryness more quickly than others.
Water Quality Matters
Air plants prefer slightly acidic to neutral water (around pH 5.5–7.0). Rainwater is ideal because it is naturally soft and free of chlorine. Filtered or spring water are also good options. Avoid distilled water, as it lacks the minerals air plants need.
Tap water can be used in some areas, but it may contain chlorine or high levels of dissolved minerals that can build up on the leaves. If tap water is your only choice, using a basic filter can help improve its quality.
Always use lukewarm water. Avoid water that is too cold or too hot, as extreme temperatures can stress the plants. If necessary, allow the water to sit at room temperature before soaking.
What Is the Best Way to Water an Air Plant
Watering air plants is not the same as watering regular houseplants, which can be confusing for beginners. The best approach depends on your plant’s situation, but generally there are 3 common methods:
Soaking
For removable air plants, soaking is the most effective method. Air plants absorb water and nutrients through their leaves. Place the plant in water and let it soak completely for 20–60 minutes. If your air plant is flowering, keep the flowers above the water to prevent them from rotting.
After soaking, remove the plant and gently shake off the excess water. Place the plant upside down or on its side in a spot with good airflow. Let it dry completely for two to three hours. Pay special attention to the base. If it still feels cool or damp, the plant needs more drying time. Retained moisture in the center can cause rot and eventually kill the plant.
Spraying
If your air plant is glued or mounted and cannot be easily removed, spraying is a good alternative. Use a spray bottle, or gently pour water over the plant until the leaves are thoroughly wet. Shake off the excess water, and make sure that it has good air circulation (such as near a clip-on fan), so that it can dry completely.
Misting
Misting is best used as a supplement, not a primary watering method. Using a plant humidifier or lightly misting the plant can help increase the surrounding humidity, especially in dry environments. However, misting alone usually does not provide enough water to keep air plants healthy in the long term.
FAQs
Q1: How to water air plants in the winter?
Water them thoroughly about once a week. Soak removable plants and spray mounted or glued ones. Between waterings, lightly mist them or use a plant humidifier to increase humidity. If your indoor air is very dry, water them more often.
Q2: Can air plants go 2 weeks without water?
Yes, most air plants can survive two weeks without water if they are well-hydrated beforehand. For longer absences, give them a long soak of up to 12 hours before leaving. Soak them again when you return.
Q3: Where to place your air plant?
Place your air plant in bright, indirect light. An east-facing window is ideal for gentle morning sun. A west-facing window works, too, but filter the harsh afternoon light with a sheer curtain, or place the plant a few feet back. If natural light is limited, use a plant grow light.
