Air plants, also known as Tillandsia, are unique and versatile plants that bring a touch of greenery to your space without the need for soil. These plants are native to forests, mountains, and deserts, and they have evolved to absorb moisture and nutrients from the air. As a result, how often you should water your air plant depends on a variety of factors like climate, humidity, and the specific type of air plant you have.

Generally speaking, air plants need to be watered once a week on average. The most common method of doing this is by giving them a soak in a water bath for about an hour. However, the specific duration may vary based on your location’s humidity and temperature. In more humid environments, shorter soaking times might be sufficient, while air plants in dryer climates may need water for a bit longer.

It’s essential to keep an eye on your air plant and adjust your watering routine accordingly. Signs that your air plant may need more water include curling or drying leaves. By paying attention to your air plant’s needs, you can ensure it remains healthy and vibrant in your care. Remember, these guidelines are a starting point, and you may need to adjust them based on your plant’s specific requirements and your environment.

Understanding Air Plants


Air plants, also known as Tillandsias, are unique and versatile plants that do not require soil to grow. They are epiphytic, meaning they absorb moisture and nutrients from the surrounding air through their leaves, rather than from rooting systems. These plants have specialized cells called trichomes that help them take in water and nutrients directly from the atmosphere, making their care quite different from other traditional houseplants.

Air plants come in a variety of species and shapes, making them attractive and interesting additions to your indoor garden. Despite their lack of roots, they still require attention to maintain a strong and healthy appearance.

Natural Habitat

Air plants naturally thrive in tropical and subtropical climates, primarily found in Central and South America, as well as the southern United States. As such, they prefer warm temperatures and moderate to high humidity levels to survive.

Given their original environment, it is essential to simulate the natural habitat of air plants when caring for them indoors. This means providing appropriate air circulation, light, and of course, water.

When it comes to watering air plants, on average, you should soak your air plant for 20 minutes once a week. However, the frequency and duration of watering may vary depending on your climate. If you live in a hot and humid climate, your air plants may require more frequent soaking, whereas in a drier environment, it might need less.

For example, if the humidity is very high where you live, a 20-minute soak may be sufficient for your air plants, but in a dryer climate, they might need to be soaked for up to 4 hours occasionally. Additionally, during summer months with higher temperatures, you may need to water your air plants more frequently, while in cooler conditions, their need for water may decrease.

Watering Frequency

General Guidelines

Air plants need to be watered differently compared to other houseplants, and the frequency depends on various factors. As a general rule, let your air plants soak in a water bath for about an hour once a week. This schedule should be adjusted according to your climate, as humidity and dryness can affect their water needs. If you live in a humid area, a 20-minute soak might be sufficient, while in a dry climate, a soaking of up to 4 hours may be required.

Factors Affecting Water Needs

  1. Seasonal changes: During warmer months, like summer and early fall, air plants might need watering two to three times a week as they dry off faster. You can begin with 15-minute soaks once or twice a week and adjust according to the plant’s response.
  2. Misting vs. soaking: Misting your air plant every 3 days could be enough, but occasionally, it’s beneficial to submerge the plant as the mist might dissipate before the plant assimilates the moisture. On the other hand, soaking the plant can keep it refreshed for up to 10 days, while misting lasts for only 2-3 days.
  3. Individual plant differences: Different air plant species have varied water requirements. Keep an eye on their condition and adjust watering frequency accordingly.

Remember to check your air plants’ progress and tweak the watering routine if necessary. It’s essential to keep track of your specific environment and species to ensure optimal growth and health.

Watering Methods

When it comes to watering air plants, there are a variety of methods you can use to keep them healthy and well-hydrated. In this section, we’ll explore three popular approaches: misting, soaking, and dipping.


Misting is a gentle method of watering air plants, which involves spraying a fine mist of water onto the leaves. This process can be performed about every three days to ensure your plants receive the necessary moisture. Misting is especially useful for air plants that are mounted in a way that makes soaking difficult or impossible. However, it’s important to note that occasionally, air plants that are primarily misted may still benefit from a full submersion.


Soaking is a widely recommended method of watering air plants, particularly for those who live in drier climates or have plants with thicker leaves. To soak your air plants, simply fill a sink or bowl with room-temperature water and submerge each plant for 30 to 60 minutes. After removing the plants from the water, gently shake off any excess moisture, and set them upside down on a clean cloth or paper towel to drain for an hour or two. This process should typically be done once a week, but if you live in a humid area, you may reduce the soaking time to 20 minutes, while in extremely dry climates, it could last up to 4 hours.


Dipping is another method to water air plants, and it involves briefly dipping the plants into a water source, such as a bowl or sink. Dipping can be done more frequently than soaking but may not provide as much moisture. It’s essential to remember that, similar to the other watering methods, the frequency and duration of dipping will be influenced by the specific needs of the air plant variety and the environmental conditions in which they’re grown.

In summary, the optimal watering method for your air plants will largely depend on factors such as climate, plant variety, and mounting options. Misting, soaking, and dipping each offer their own advantages, so choose the one that best suits your air plants’ needs and adjust the frequency accordingly to maintain their health and vitality.

Troubleshooting Common Issues

Overwatering Signs

The key to keeping your air plants healthy and happy is to give them just the right amount of water. Overwatering can lead to problems like rot and fungal growth. Some signs that you might be overwatering your air plants include:

  • Yellowing leaves: When the leaves start to turn yellow, it’s often an indication that the plant is receiving too much water.
  • Soft, mushy base: A healthy air plant should have a firm base. If it becomes soft and mushy, it’s probably holding on to excess water, which can cause rot.
  • Foul smell: A rotting air plant will typically emit a foul smell. If you notice an unpleasant odor coming from your plant, it’s likely suffering from overwatering issues.

Prevent overwatering by ensuring your plants completely dry out within 4 hours after watering, and adjust your watering frequency accordingly.

Underwatering Signs

On the other hand, underwatering can cause your air plants to suffer from dehydration and even death. Watch for these signs to determine if your plants need more water:

  • Curled leaves: If your air plant’s leaves start to curl inward, it’s a sign that they’re trying to retain moisture and are in need of more hydration.
  • Brown leaf tips: Dry, brown leaf tips may indicate that your plant is not receiving enough water, especially if it occurs in combination with other underwatering signs.
  • Crispy texture: An underwatered plant will often have a crisply dry texture when touched. This is a clear sign that it needs more water.

To avoid underwatering your air plants, soak them in a bowl of water for 20 minutes to 1 hour each week and mist them between waterings to maintain their humidity levels.

Remember that each air plant is unique and may require specific care. Monitor your plants closely and make necessary adjustments to their watering routine to ensure their health and wellbeing.

Additional Tips for Air Plant Care

Light Requirements

Air plants thrive in bright, indirect sunlight. Place your air plant near a window with filtered light, skylights, or fluorescent lighting. Direct sunlight may be too intense, especially during hot summer months, and can cause the plant to dry out or become sunburnt. If you notice your plant’s leaves turning yellow or brown, it might be receiving too much sunlight, so consider relocating it to a shadier spot.

Temperature Preferences

Air plants prefer temperatures between 50-90°F (10-32°C). They can tolerate occasional temperature fluctuations, but consistently high or low temperatures can cause stress and ultimately lead to the plant’s demise. Avoid placing your air plant directly above or below heating or cooling vents. Air plants can also be sensitive to sudden temperature changes, such as drafts from open windows or doors.

Air Circulation

Good air circulation is essential for the health of air plants. Stagnant air increases the risk of rot, especially after watering. Keep your air plants in a space with adequate airflow, such as near a window or by using a small fan. Avoid placing your air plants in small, enclosed containers without air holes, which can trap moisture and reduce airflow. If you choose to use a glass terrarium or container, be sure to select one with an opening to allow air to circulate.

Don’t forget to water your air plants regularly by soaking them for 30-60 minutes once a week. After the soak, gently shake off excess moisture and place the plants upside down on a clean cloth or paper towel to drain for an hour or two. Following these care tips will help keep your air plants happy and healthy.
