Air Plant Care

Air plants, known for their resilience and unique ability to grow without soil, have gained popularity as intriguing, low-maintenance houseplants. Properly known as Tillandsias, these plants absorb water and nutrients through their leaves, making them an interesting addition to any indoor garden. Understanding how to care for them ensures they thrive and bring a touch of nature’s wonder into your home.

Scientific Classification

Every living thing has a unique place in the tree of life. Air plants, or tillandsias, are no different. Their exact scientific name and group tell us about their family tree. Here’s where they fit:

  • Kingdom: Plantae
  • Division: Bryophyta
  • Class: Bromeliopsida
  • Order: Bromeliales
  • Family: Bromeliaceae
  • Genus: Tillandsia
  • Species: There are over 650 species of air plants


Light is crucial for the well-being of your air plant. These plants need bright, indirect sunlight to thrive. Think of placing them near a window, but not directly in the hot sun. Direct sunlight can be too harsh and may scorch the leaves. In contrast, low light might not provide enough energy for your air plant to grow properly. Natural morning light is best because it’s more gentle. If natural light is limited, you can use artificial grow lights. Place them under these lights for about 12 hours a day. Remember to avoid putting your air plants in places where they won’t get any light, like a dark room. They need light to make food for themselves through a process called photosynthesis. This keeps them healthy and helps them develop vibrant colors.


Air plants, also known as Tillandsias, need water to survive. Unlike other plants, they don’t grow in soil and get moisture from the air. You should water them by misting or soaking, depending on the humidity in your home. In a humid environment, mist air plants two to three times a week. If it’s drier, soaking them in water for 20-30 minutes every one to two weeks is best. After soaking, shake off excess water to prevent rotting. It’s important to use room temperature water and let them dry before placing them back in their spot. Remember, too much water can harm your air plant, so make sure they are not left soggy.


For air plants, soil is a bit of a trick question. You might think all plants need soil, but air plants break that rule. They don’t require any soil at all to grow. This is because they are a type of plant known as epiphytes. Epiphytes attach themselves to other things, like tree branches, instead of growing in the ground. So when it comes to air plant care, forget about soil. Instead, you’ll focus on providing them with the right light, water, and air circulation. They absorb what they need from the air and occasional waterings. This is a neat adaptation that sets air plants apart from many other houseplants you might know.


When you’re taking care of air plants, temperature is important. These plants prefer things not too hot or too cold. Think of the climate where you’re comfy in a T-shirt; that’s what air plants like. They thrive in temperatures ranging from 50 to 90 degrees Fahrenheit. If it gets colder than 50, they can get damaged. When it’s hotter than 90, they might get stressed and dry out. You should keep your air plants away from cold drafts and hot heaters. Place them in a spot with a stable, moderate temperature. During winter, be extra careful to keep them warm and cozy. If you take care of the temperature, your air plants will grow happily.


Humidity is the amount of moisture in the air. Air plants need the right level of humidity to thrive. They come from environments where the air often feels moist. This means you should aim for a room with a fair amount of water in the air. But it shouldn’t be too damp, as too much moisture can harm them. A good humidity range for air plants is between 40% and 70%. To increase humidity, you can mist your air plants with water. Keep them in a well-ventilated space so they dry properly between waterings. If the air is too dry, the leaves of your air plants might start to curl or crack. Therefore, check on your air plants regularly to make sure they have the moisture they need.


Fertilizer is like food for your air plant. These plants get most of what they need from the air. Still, they sometimes need extra nutrients. Think of fertilizer as vitamins for your plant. You can spray a special liquid on the plant or mix it with water. It’s important not to overdo it. Too much fertilizer can harm your air plant. A small amount once a month is enough. Always follow the instructions on the fertilizer package. This will help your air plant stay healthy and grow.

Size & Growth Rate

Air plants come in various sizes and they grow at different speeds. These plants usually stay small, fitting in the palm of your hand. Some air plants can be as tiny as a couple of inches, while others might grow to be over a foot wide. Air plants grow slowly. You may not even notice them getting bigger day by day. But over months or even years, you’ll see the change. They don’t have a fast growth rate like some other plants. This means you don’t have to worry about them quickly outgrowing their space. Remember, each type of air plant grows at its own rate. Therefore, if you have more than one kind, you’ll see that some may get bigger faster than others. Keep a lookout for baby air plants, known as “pups,” which can appear at the base of the plant after it flowers.

Common Issues

Often, your air plant might not look healthy. It could be turning brown or wilting. These signs usually mean something is off with its care. For example, too much sun can scorch the leaves, making them look burnt. Or, not enough water might make them dry and brittle. Sometimes, air plants get too much water. This can lead to rot, where the plant looks black or mushy. Pests like aphids or scale might also harm your air plant. They suck the sap and weaken the plant. If you see tiny bugs or sticky residue, pests could be the problem. Therefore, keep an eye on your plant for these issues. That way, you can catch and fix them early.


Toxicity is about how poisonous a plant is to humans and animals. Air plants are safe and non-toxic. You don’t have to worry about them making you, your kids, or your pets sick if touched or eaten. However, always be careful and keep any plant away from small children and pets, just to be on the safe side. Not all plants are as safe as air plants. Always check if a new plant is toxic before bringing it into your home. This way, you’ll keep everyone safe.
