To successfully grow air plants, it's essential to understand their unique requirements, such as proper watering and lighting conditions.

With the proper care, your air plants will flourish and bring beauty to your living space.

About Air Plants

Air plants, also known as tillandsia, are unique species of epiphytes belonging to the bromeliad family.

Over 650 varieties of tillandsia spp. can grow on trees and rocky surfaces, absorbing nutrients and moisture from the air.

Tillandsias are popular for their low-maintenance care, as they do not require soil to grow.

Some common types of air plants include the sky plant (T. ionantha), bulbous air plant (T. xerographica), and T. usneoides.

They thrive in bright, indirect sunlight and need proper watering and air circulation to prevent rot and mold.

Growing Air Plants

To grow air plants, it's essential to understand that they don't require soil but need a suitable environment to thrive.

They are epiphytes, using their roots to latch onto various supports like tree branches, rocks, or even decorative items such as shells, slate, or coral.

Since air plants primarily grow in the United States, Mexico, and Central America, you can display your plants in glass globes, terrariums, or by attaching them to materials like cork or logs to mimic their natural habitat.

Be creative when arranging your air plants, as they come in various varieties, such as Caput-Medusa, Maxima, and others native to regions like California and Mexico.

Propagation of air plants is commonly done by pups or offshoots, although it is possible to grow them from seed in some instances.

Caring for Air Plant

Sun and Temperature

Air plants need a balance of sunlight and shade. They thrive in indirect light, so place yours near a window but not in direct sunlight.

Ensure the temperature is between 50-90 degrees Fahrenheit for optimal growth.

Water and Humidity

To water your air plant, soak it in a bowl of distilled water for 20-40 minutes every 1-2 weeks.

Ensure your plant dries completely after watering to prevent rot by placing it upside down on a towel. Humidity levels around 40-60% are ideal for air plants.

Soil and Fertilizer

Air plants do not require soil for growth. They absorb nutrients through their trichomes, tiny hair-like structures on their leaves.

Feed your air plant with bromeliad food or a low-nitrogen fertilizer once a month to provide the necessary nutrients.


As air plants don't require soil, there is no need for conventional repotting.

However, you can change the mounting or display of your air plant as it grows to provide more space or accommodate its new size.

Pruning and Propagation

Prune dead or damaged leaves with clean scissors to maintain the health and appearance of your air plant.

When your plant produces offsets, or "pups," you can gently separate them from the mother plant to propagate new air plants.

Troubleshooting Plant Problems

Growing Problems

Air plants, as epiphytes, grow without soil and can experience problems such as overwatering and underwatering.

To remedy this, soak your air plant in water for 20 minutes to 1 hour every 1 to 2 weeks.

Avoid excessive sun exposure and maintain proper plant temperature and air circulation.

Air plants are slow growers, taking months to germinate and years to mature. Be patient with your plants, especially during their initial growth phases.

Pests and Diseases

Pests and diseases can pose challenges for your air plants. Keep an eye out for insects, such as spider mites or mealybugs.

If you notice pests on your plants, gently remove them with water and possibly a mild insecticidal soap.

In terms of diseases, air plants can be prone to fungal infections if they are not properly cared for.

To prevent fungal issues, ensure that your plants are not left sitting in water for extended periods, and always dry them thoroughly after watering.


Caring for air plants is quite simple once you understand their unique needs.

Remember to provide them with adequate light, water, and temperature for optimal growth and health.

Soak your air plants in water for 20-40 minutes every 1-2 weeks, and place them in a well-lit area, ideally with indirect sunlight.

Following these basic guidelines allows you to grow and maintain thriving air plants without needing soil, adding a fascinating touch of nature to your home or office.

Frequently Asked Questions

What is the proper way to water an air plant?

To water your air plant, submerge it in room-temperature water for 20-30 minutes. After soaking, remove the plant from the water and shake off any excess water.

How can I display air plants indoors?

Air plants can be displayed in various ways, including mounted on driftwood or cork, placed in decorative containers or terrariums, and even hung from the ceiling with wire or fishing line.

What type of containers are best for air plants?

Air plants thrive in containers that allow good air circulation, such as wire or mesh holders, glass globes, or open terrariums. Avoid containers that trap moisture, as that can lead to rot.

Can air plants grow without being attached to anything?

Yes, air plants can grow without being attached to anything. They absorb moisture and nutrients from the air, allowing them to be placed almost anywhere as long as they receive proper care.

What are the ideal conditions for air plant terrariums?

Ideal conditions for air plant terrariums include bright, indirect light, good air circulation, and regular misting or soaking. Avoid placing terrariums in direct sunlight or areas with extreme temperature fluctuations.

How large do air plants typically grow?

Air plant size can vary depending on the species, but most air plants grow between 1 and 12 inches in size. Some species may continue to produce smaller pups or offsets, which can be separated and grown into new plants.
