How Cold is Too Cold for Tillandsias

As the icy chill of winter creeps in, you may be concerned about the well-being of your beloved tillandsias. After all, you want those fuzzy little fellows to stay alive and thriving for as long as possible! But how cold is too cold for Tillandsias?

Tillandsias are generally quite resilient and can withstand temperatures as low as 10°C (50°F). However, you should never let them put outside if the temperature is below 45°F or 7°C. If the temperature drops below this, you should consider moving them indoors until the weather warms up again.

Let’s explore the question of how cold is too cold for Tillandsias and provide you with all the information you need to keep your air plants healthy and thriving.

How Cold Can Tillandsias Tolerate?

Tillandsias are a hardy plant species that can withstand a wide range of temperatures. However, there are limits to the cold temperatures that they can tolerate. Here are some key points to keep in mind:

The specific temperature range that Tillandsias can tolerate varies depending on the species and their origin. In general, most Tillandsias prefer temperatures between 50-90°F (10-32°C).

Some species, such as Tillandsia tectorum and Tillandsia ionantha, are more cold-tolerant than others and can handle temperatures as low as 45°F (7°C) for short periods of time.

Cold tolerance also depends on the health and maturity of the plant. Young, weak, or recently transplanted Tillandsias are more susceptible to damage from cold temperatures. Excessive colds can cause Tillandsias to suffer from frostbite, which results in discolored leaves and tissue damage. In severe cases, the plant may die.

It’s best to avoid exposing Tillandsias to temperatures below 40°F (4°C) for prolonged periods of time. If you live in an area where temperatures regularly drop below this threshold, you may need to take extra precautions to protect your plants.

What Temperature Range Do Tillandsias Prefer?

Tillandsias, also known as air plants, are native to tropical regions of South and Central America, where temperatures tend to stay relatively warm year-round. As a result, they prefer warmer temperatures than many other houseplants. However, they can tolerate a wide range of temperatures as long as they are not exposed to prolonged extreme heat or cold periods.

Here are some temperature ranges that Tillandsias generally prefer:

  • Daytime temperatures: Most Tillandsias prefer temperatures of 70-90°F (21-32°C). This temperature range is ideal for their growth and flowering.
  • Nighttime temperatures: Tillandsias can tolerate nighttime temperatures that are slightly cooler than daytime temperatures. A range of 50-70°F (10-21°C) is generally considered acceptable.
  • Temperature fluctuations: While Tillandsias prefer a relatively stable temperature range, they can tolerate fluctuations as long as they are not extreme or prolonged.

What Are The Risks Of Exposing Tillandsias To Cold Temperatures?

Tillandsias, like all plants, have specific temperature requirements to thrive. When exposed to temperatures outside their preferred range, these air plants may experience a range of negative consequences. Here are some risks associated with exposing Tillandsias to cold temperatures:

  • Frost Damage: Tillandsias are sensitive to frost and can easily be damaged or killed by exposure to freezing temperatures. Frost damage can cause the plant’s leaves to turn brown, black, and wilt.
  • Slow Growth: When exposed to temperatures that are too low, Tillandsias will slow down their growth rate. This can be problematic if you are trying to propagate or grow them for ornamental purposes.
  • Root Rot: When Tillandsias are exposed to cold temperatures, and their growth slows down, the risk of root rot increases. This is because the soil will remain moist for longer periods, creating a breeding ground for fungi and bacteria that can damage the plant’s roots.
  • Stress: Exposing Tillandsias to cold temperatures can be stressful for the plant, causing it to divert energy away from growth and repair to deal with the stressor.

How To Protect Tillandsias From Cold Temperatures?

Tillandsias can be protected from cold temperatures in a few ways, including:

Move Tillandsias Indoors

If you live in an area with cold temperatures, you can move your Tillandsias indoors during winter. Indoors, they can thrive in temperatures between 60-80°F (15-27°C).

Cover Tillandsias

If you want to keep your Tillandsias outdoors, you can protect them from the cold by covering them with a cloth or blanket during the night. This can help retain heat around the plant and protect it from freezing temperatures.

Use A Greenhouse

If you have a greenhouse, you can move your Tillandsias into it during the winter. Greenhouses can provide a controlled environment with the right temperature, humidity, and light for Tillandsias to thrive.

Use Grow Lights

If you are growing Tillandsias indoors, you can use grow lights to provide the necessary light and warmth for the plants. Grow lights can help simulate their natural habitat’s natural light and temperature conditions.

Use A Heat Source

 In areas with extremely low temperatures, you may need to use a heat source to protect your Tillandsias. You can use a space heater or heat lamp to keep the air around the plants warm.

How To Revive Tillandsias That Have Been Exposed To Cold Temperatures?

Tillandsias can recover from cold damage if the damage is not severe. However, reviving them requires careful attention and patience. Here are some steps to revive Tillandsias that have been exposed to cold temperatures:

Assess The Damage

Take a closer look at your Tillandsias to determine the extent of the damage. You may notice discoloration or browning of the leaves. If the damage is severe, it may be irreversible, and you may need to consider replacing the plant.

Remove The Damaged Leaves

Once you have assessed the damage, carefully remove the damaged leaves with a pair of sterilized scissors. Cut the leaves close to the base of the plant, taking care not to damage any healthy leaves or the center of the plant.

Increase The Temperature

Move your Tillandsias to a warmer location with a temperature range of 60-80°F. Avoid exposing them to direct sunlight or hot, dry air, which can further stress the plant.

Increase Humidity

Tillandsias require high humidity to thrive, especially when recovering from cold damage. Increase the humidity around the plant by misting it with water several times a day or by placing it in a humidity tray.

Provide Proper Care

While your Tillandsias are recovering, ensure they receive proper care. Water them regularly, but avoid overwatering, as this can lead to root rot. Also, provide them with adequate air circulation to prevent fungal growth.


Tillandsias are fascinating plants that can bring beauty and life to any indoor or outdoor setting. While they are hardy and low-maintenance, you need to understand the temperature requirements of these plants to ensure their health and survival.

Too much exposure to cold temperatures can be detrimental to Tillandsias, but there are steps you can take to protect them and revive them if they have been damaged. By following the guidelines outlined in this article, you can ensure that your Tillandsias thrive and bring joy to your space for years to come.
