There is a valid explanation behind the moniker air plants. They lack the roots that other plants have to draw moisture from the soil. The air around air plants serves as their source of water and nutrients. These plants absorb the moisture they require from humidity and rain water via microscopic, hair-like growths on their leaves known as trichomes. Despite this clever trick, air plants cultivated as indoor plants typically need regular watering. That’s because our homes often have relatively dry air (and hopefully rain-free). Follow these professional recommendations for the best technique, frequency, and type of watering to effectively hydrate your air plants.
How does water absorb by air plants?
Tillandsia air plants use their leaves to absorb water. Not their roots; they mostly use them to affix to things like wood or other plants.
Trichomes give most air plants their velvety appearance. They have structures that resemble hairs and use them to absorb water. Some air plants’ trichomes give them the appearance of being dusted with white powder.
How should an air plant be watered to avoid wetting it?
Most air plants with plenty of trichomes (xeric plants) should be often misted or soaked, whereas mesic plants, which have bright green leaves and less trichomes, prefer to be drenched only once a week. In our blog post Mesic Vs Xeric Air Plants, we go into further detail regarding the differences between Xeric and Mesic plants. However, there is one exception to this rule: air plants with bulbous bases, even those with bright green, smooth leaves, should frequently not be wet for extended periods of time as well. Because of water buildup in their bulbous bases, plants are susceptible to internal rot.
Instead of being wet, Xerographica air plants should be sprayed or submerged. These plants, which are xeric in nature, are indigenous to arid areas. These plants can survive more sun and less water. A xerographica should be submerged in a basin or pail of water, then gently shaken to let the water drip off the leaves. To prevent water from getting stuck in the leaves, let the item dry upside-down.
The Tillandsia tectorum is an air plant that you shouldn’t wet because it has a lot of fuzzy leaves. The tectorum’s large trichomes on its leaves aid in absorbing moisture from the surrounding atmosphere. These plants have evolved to survive without much precipitation and are naturally found in arid areas of Ecuador and Peru. Depending on how hot and dry it is where you live, we advise spraying these guys every other week or so. They also favor open air and strong light.
The distinctive feature of bulbous air plants is that they have what are known as “pseudobulbs.” In the natural, ant colonies construct their nests inside of these hollow onion-shaped bulbs, which are essentially hollow themselves. When watering these plants, especially when soaking them, exercise caution. These so-called pseudobulbs are susceptible to water intrusion, which can cause the plant to rot from the inside out. You can either submerge them in water and shake off the extra afterward, or you can hold them under running water while avoiding their bases. The T. caput medusae, T. bulbosa, T. pruinosa, T. pseudobaileyi, T. butzii, and T. seleriana plants are included in this group.
Another reason not to soak T. pruinosa and T. seleriana is that they both have a lot of trichomes. They could decay from soaking because of too much water.
You shouldn’t immerse air plants with delicate leaves like T. fuchsii v gracilis and T. andreana. These plants benefit more from light misting or rapid dunks. You may need to spritz these plants as frequently as every couple of days to make sure they are receiving enough water because of their thin, wispy leaves, which can cause them to dry out more quickly between waterings.
The Tillandsia magnusiana should be misted or dipped rather than soaked because it has a lot of trichomes. These plants’ form and trichome content can make them more prone to decay.
When watering air plants that are in bloom, exercise caution to avoid getting the blossom itself wet. While it would be acceptable to soak the plant’s bottom leaves, we frequently advise pouring water over them or immersing them to avoid wetting the blossom. A bloom that has been moist for a long time may develop rot, which may eventually spread to the leaves and kill the plant.
In nature, how do air plants obtain water?
Although air plants are typically fairly easy to maintain, watering is often the deciding factor. But don’t worry! To make things simple and easy, we offer some tips and tricks.
Air plants acquire their nutrients from rainwater, bird droppings, and dead insects in their natural habitat. The greatest choice would be if you have access to a pond, creek, lake, or well, or if you can collect rainfall.
Neither filtered water nor tap water should be used. Municipal tap water typically contains more chemicals than minerals. Many of the natural minerals and nutrients that are advantageous to air plants have been removed from filtered water.
Depending on the weather and time of year, it is ideal to bathe your air plants for 20 minutes to an hour once per week to 10 days. Because cold or hot water will shock the air plants, the water should be lukewarm. If you choose to mist your air plants only, be sure to do it once daily, or as frequently as necessary. When misting your plants, be sure to water all of the leaves just enough to prevent them from dripping, but not too much.
It is crucial to allow your air plants to completely dry after soaking or misting them, especially before putting them back into a terrarium or other container. Place your air plants in some indirect sunshine to make sure they dry. Like drying a cup, you can place them upside-down on top of a towel and allow the water trickle down the leaves. As air plants are highly prone to rotting if they are left wet for too long, give them a few hours to completely dry.
What month is it in the year? Are you frequently using your heater? Do you reside in a humid or arid environment?
You may more accurately assess how much water your air plants need by taking into account all of these elements. Your plant will require more regular watering if you reside in a dry region than if you do in a humid one.
The time of year might also affect when to water. You will need to water more in the summer because the air is hotter and dryer. Your air plants may require a little less water in the winter because the weather will be cooler and more humid. However, if you have a heater on or are using a fireplace, this will also slightly dry the air.

An air plant’s best formula for success is proper care. Despite the fact that air plants are among the easiest indoor plants to care for, it is still preferable to give them some attention. Taking care of your air plants include giving them the water they require, the right amount of light, appropriate airflow, and fertilizers like orchid plant food to improve their health.
Without water, air plants may survive for two weeks. Additionally, the plant’s health is compromised even if it is still alive. Regarding the recommended watering regimen, you should bathe your air plants in water at least once every two weeks and spritz them once a week.
They will stay hydrated and have all the moisture they need to perform essential functions like photosynthesis if they are often watered. But what happens if you are unable to water your air plants on time? How long can they go without drinking?
To shed further light on this subject, we have put together this extremely useful post. Are you scared that your air plants will wither while you are away since you plan to be gone from home for a few days? Or perhaps you’re too busy with your schedule to give your air plants the proper amount of water? If so, you should read this article! Learn how long it takes for the absence of water to actually harm your air plants by reading on.
How long does an air plant live?
Perennial plants are tillandsias, also referred to as air plants. According to the source, they have a lifespan of between two and five years, which indicates that they normally survive longer than two years.
The type of air plant and the growing conditions have an impact on how long they live, though. They reside in deserts, on various surfaces, and on tree branches in their natural habitat (other surfaces they can grow on).
Air plants only experience one flowering during their existence, which marks the culmination of their development and maturity.
Depending on the species, the flowers might remain in bloom for a number of months. However, the air plant will begin to die when the blossoms start to wilt and fade. Air plants develop pups or offsets before they die to carry on the same growth cycle.
Despite the mother plant dying, you can take the pups out and raise them separately. Separating the pups from the mother is referred to as “division is a method of air plant propagation.
As an alternative, you might leave those puppies grouped together ” (also known as “tillandsia balls).
Could you simply sprinkle the plants?
The final technique in our series on watering air plants is misting, which you can employ in between regular soaking or immersing. Read more in our earlier blog posts to learn more about the dunk method and soaking.
If you notice that your plant’s leaves are starting to seem a bit dry or if you live in a dry region with low air humidity, misting is an excellent approach to give it a little additional hydration. Misting is probably not enough water for your plant to grow, therefore you shouldn’t utilize this method as its only supply of water.
The T. tectorum, which has a lot of trichomes, is an exception to this rule and prefers misting to soaking or submerging. In a temperate area, you might only need to mist once a month with one of these guys, or once a week in a hotter environment.
In contrast to other plants with bigger leaves, plants with wispy leaves such the T. ionantha, T. andreana, or T. fuchsii v gracilis may require misting more regularly in addition to weekly watering.
- It’s easy to spritz plants; just use a spray bottle or hose attachment set to the “mist” setting. Make sure the entire plant gets soaked before misting. As previously mentioned, if this is their sole source of water, this is not the greatest approach for watering. If you mist your plants, remember to additionally soak or dip them once a week at the very least.
A useful generalization to remember is that a healthy air plant will have leaves that are wide open, whereas a dehydrated air plant would have leaves that curl inward. Bring on the mist if you see that your plant is starting to appear a touch dry between your regular waterings!
Can air plants be watered with tap water?
I wanted to go into more detail about this because our Facebook Page gets a lot of questions about how to water air plants. Although tillandsia, often known as air plants, are simpler to maintain than many other plant species, they still need some care and attention, and water is crucial to their general well-being. Here are some frequently asked questions about watering air plants along with our suggestions:
This mostly relies on your climate, where you’re keeping the air plants, the Tillandsia species itself, and the environment in which it naturally grows (learn more about mesic vs. xeric air plants here). Since most of the year is humid where we live in Tampa, Florida, we don’t run the heat in our home as often as our friends in the north do (I’m not trying to pick on them, I swear!). We typically water our plants twice a week, but drier climates require more frequent watering. Depending on the season, you may discover that you need to water your plants less. Additionally, it depends on where you put them at your house or office. The plants will stay more wet in a humid bathroom, but you’ll probably need to water them more frequently if they’re close to an air vent or a heat source. (Note: We don’t advise keeping your plants close to heat sources.)
It should be noted that while humidity might slow down drying, it in and of itself is insufficient for watering.
Again, you should modify your watering practices according to your climate and the species of your air plants, but for the majority of air plants and surroundings, we advise that you immerse your plants in water at least once a week. Use something that allows you to totally submerge the air plants, like a bowl, bucket, or your sink. Give them a lengthier bath for an hour or more every other week if you live in a dry area. Soak for 30 to 60 minutes at least once a week. You might wish to shorten the soaks if you reside in a location with higher humidity or if your air plant is more xeric in nature.
You should allow the air plants to completely dry after soaking. They can either be let to dry with their leaves facing down or turned over and gently shaken. If water is allowed to sit in the leaves, the plants risk rotting. The plants should be placed in an area with sufficient airflow, and they should be able to dry entirely in less than four hours. Before bringing your plants back home, ensure sure they are entirely dry if they are in a globe or terrarium.
You will observe how open and wide the leaves are after soaking your plants, as well as how much more “happy” they seem. A well hydrated air plant should appear like this! You’ll learn over time that if the color starts to look a little dull and the leaves start to close or curl, your tillandsia are thirsty and you should give them another nice wash. Try soaking your air plant for several hours or even overnight if it is really struggling to see if you can rehydrate the plant. Always allow them to totally dry off before soaking or spraying them once more.
Between waterings, you can spray the plants. If you live in a dry region, this might be a terrific method to keep plants healthy and offer them some additional care. However, unless you have one of the few species of air plants that appreciate low moisture, such as T. tectorum (for which we only advocate misting) or T. xerographica, misting is not a replacement for a thorough soak (which we recommend dunking instead of soaking).
When it comes to water, air plants aren’t particularly finicky; most tap water is suitable, although it depends on the water quality in your location. The most nutrient-rich types of water to utilize are rainwater, aquarium water, or pond water. If utilizing one of these types of water, don’t add any more fertilizer. Allow the water to rest for several hours to allow the chlorine to dissolve if you’re using tap water (maybe 24 hours in some areas.)
Use water that is not distilled since it is too “pure” and will deprive the plants of the nutrients they require. Additionally, artificially softened water should not be used since Tillandsia cannot tolerate its high salt concentration.
We advise soaking your air plants in the morning so that they can dry completely over the day. Additionally, air plants utilize the nighttime hours to breathe carbon dioxide, so if they are wet in the evenings, they won’t be able to do so effectively. This method is known as CAM; to learn more about CAM, read our page on how air plants breathe. You can check on them before you go to night and place them back in their terrariums or displays. Some indirect sunlight will help them dry more rapidly.

Regarding watering the plants with blooms, I have a query. How do you water them if, as I understand it, you don’t moisten the bottoms or the blooms? Do you bring all of your indoor air plants inside during the winter? Although it doesn’t get very cold very often where I reside in Largo, Florida, it does occasionally. Since we don’t have snow, I believe the wind to be the main issue with the cold. Please lend me any assistance you can.
I recently purchased an aquarium, and in order to ensure that my three air plants receive continuous moisture in the office, I planned to tie them to a branch and let them sit on top of the tank. Do I still need to sprinkle and soak them as usual if the water that has evaporated from the tank should be plenty for them to receive?
Our well water passes through a water softener, which I should have mentioned in my previous query. They would be set up here if they could just survive on smoke.
Since we live in north-eastern Washington, rain has not been an option for us. Instead, we use well water, which I won’t even drink. I use spring water to water my air plants because I purchase it and drink it. I haven’t had them long, but they seem to be doing fine. Is using spring water for irrigation problematic?
Due to hydration issues, I do not advise attaching air plants to driftwood. In retrospect, it sounds apparent, but I was new to air plants and lost five of my six because the wood kept too much water when I first gave them a soak.
