Air Plant Sunlight: Do They Need It and How Much?

Air plants do need sunlight to thrive, but they prefer bright, indirect light. Exposure to direct sunlight for extended periods can cause the leaves to burn and become damaged. Placing your air plants near a window with filtered light or in a well-lit room is ideal. If you’re growing air plants outdoors, provide them with dappled shade or hang them under an awning or tree to protect them from harsh sunlight.

Air Plant Soil Tips

One of the most intriguing aspects of air plants is that they don’t require soil to grow. Instead, they absorb nutrients and moisture from the air through their leaves. This makes them incredibly low-maintenance and allows for a wide range of creative display options, such as mounting them on driftwood, placing them in glass terrariums, or hanging them in decorative air plant holders.

Air Plant Watering and Frequency

While air plants don’t need soil, they do require moisture. There are two main methods for watering air plants: misting and soaking. Misting involves spraying the plant with water 1-2 times per week, ensuring that the entire plant is dampened. Soaking involves submerging the plant in water for 20-30 minutes once a week. After watering, gently shake off any excess water and allow the plant to air dry completely to prevent rot.

Pruning Air Plants Properly

Pruning air plants is a simple process that helps keep them looking their best. To prune your air plant, use a clean pair of scissors or pruning shears to remove any dead, damaged, or discolored leaves. Be sure to cut as close to the base of the leaf as possible, without damaging the main stem.

Optimal Air Plant Temperature: Can They Tolerate the Cold?

Air plants prefer temperatures between 50-90°F (10-32°C) and can tolerate a range of indoor and outdoor environments. However, they are sensitive to extreme cold and should be protected from frost and freezing temperatures. If you live in a region with cold winters, bring your air plants indoors or provide them with adequate insulation to keep them warm.

Common Air Plant Problems

Browning or Yellowing Leaves

If your air plant’s leaves are turning brown or yellow, it could be a sign of underwatering or exposure to direct sunlight. Ensure that you’re providing your plant with adequate moisture and move it to a location with bright, indirect light.


Rotted air plants are often a result of overwatering or not allowing the plant to dry properly after watering. To prevent rot, be sure to shake off excess water and let the plant air dry completely before placing it back in its display.


While air plants are generally pest-resistant, they can occasionally be affected by mealybugs or scale insects. If you notice pests on your air plant, treat the plant with a mixture of water and a few drops of mild dish soap. Gently wipe the affected areas with a soft cloth or cotton swab to remove the pests.

Air Plant Outdoors vs Indoors

Air plants can be grown both outdoors andindoors, each with its own set of advantages and disadvantages.

Location Pros Cons
  • Controlled environment for temperature and humidity.
  • Less risk of pests.
  • Year-round enjoyment, unaffected by seasonal changes.
  • May require supplemental lighting for adequate growth.
  • Less airflow compared to outdoor settings.
  • Natural light and airflow promote healthy growth.
  • Can be incorporated into outdoor living spaces and garden designs.
  • Exposure to extreme temperatures and weather conditions.
  • Potential for more pests and diseases.
  • May need to be brought indoors during cold months.

Best Pots for Air Plants

Since air plants do not require soil, traditional pots are unnecessary. Instead, consider using a variety of creative containers and displays to showcase your air plants. Some popular options include:

  • Wire or mesh baskets
  • Glass terrariums or globes
  • Driftwood, cork bark, or other natural materials for mounting
  • Decorative air plant holders designed specifically for Tillandsia

When choosing a display for your air plants, ensure there is adequate airflow and consider how the container will affect the plant’s access to light and water.

Growth Rates: How Fast Do They Grow?

Air plants generally grow slowly, with most species taking several years to reach maturity. Their growth rate depends on factors such as light, temperature, and humidity. Providing optimal care conditions will encourage healthy and steady growth.

Air Plant Lifespan

Air plants can live for several years, with some species living up to 20 years or more under the right conditions. After flowering, air plants will produce pups, or offsets, which can be separated from the mother plant to create new plants, ensuring a continuous cycle of growth.

Are Air Plants Safe?

Air plants are non-toxic and safe to have around children, pets, and other animals. However, it’s always a good idea to keep plants out of reach of curious pets and children, as ingesting plant material could cause digestive upset.

Air Plant Flowers

Air plants produce colorful and unique flowers that can last for several weeks to months. Flowering is a one-time event in an air plant’s life, and it signals the beginning of the plant’s reproductive cycle. After flowering, the plant will produce pups that can be separated and grown into new plants.
