Why Airflow is Great for the Health of Your Houseplants
Learn how to keep your houseplants healthy and thriving with our plant care guide about why good air circulation matters for indoor plants. From preventing disease to boosting photosynthesis, this guide offers practical tips for optimizing your plant care routine.
Have you noticed your houseplants struggling to thrive in your living spaces? Perhaps they are prone to disease, leaves are drooping, or you're dealing with pest infestations (often).
Your plants could be struggling because of the lack of airflow and air circulation. Good air movement is crucial for your indoor plants and their overall health. In this plant care guide, we'll discuss the five reasons why good airflow and air circulation is a great way to help your plants thrive.
These are the topics we're going to look at together:
Let's learn a little bit more about airflow and air circulation, something that's often forgotten about when taking care of plants.
Airflow vs air circulation
In this plant care guide, I'm going to use 2 terms that sound the same but are slightly different: airflow and air circulation. Let's define what each of these means before moving on, just to make the plant care guide easier to follow:
- Airflow (or breeze): the movement of air from one place to another
- Air circulation: the continuous movement of air within a space (it's circulating)
An easy example of airflow would be a fan: it's blowing wind from its propellers to wherever you're pointing it.
An example of air circulation would be to open a window in a room. By opening the window, you allow fresh air to circulate and spread out in a space. In this example, airflow causes air circulation, because the wind blows through a window into the room to bring fresh air in and let stale air back out.
Now that we know the difference, we can look at the benefits from each or these for our houseplants.
Prevents Disease
The air around our indoor plants can make a big difference to their health. Just like people, plants don't do well in stuffy, still air. It can cause all sorts of problems.
Think about a hot, sticky day with no wind. That's not comfortable for us, and it's not good for plants either. When there's no breeze, moisture doesn't dry up and stays in the air. It sits on the leaves and soil and can cause rotting and disease. Good air circulation helps to dry up extra moisture on the leaves and soil. This stops diseases before they can settle in on your plants and helps to keep your plants healthy.
According to some plant researchers, airflow can cut down on the spread of certain common plant diseases and fungi. So it's important to make sure your indoor plants get good air circulation if you're regularly dealing with these plant issues.
Later in this guide, we'll look at how you can help to improve air circulation to reduce the spread of diseases.
Strengthens Plants
Your plants aren't just happy the air circulation helps to keep them safe from diseases, but it can also stimulate the growth of stronger stems and leaves.
A gentle breeze encourages plants to develop sturdier cell structures, making them tougher and better able to deal with you handling them occasionally. However, if you give them too much of a good thing, you can damage your plant. If the airflow around your plant is too much, it could cause the plant to dry out much more quickly than you might be used to. It's all about finding the right balance.
An important thing to note is that this strengthening effect doesn't just work for young plants. Even mature plants can benefit from a gentle breeze and improved air circulation.
Improves Photosynthesis
Good air circulation does more than you might expect. Good air circulation helps the air around the plant to be refreshed constantly, which means your plant will always have a new supply of CO2 available to it.
By keeping the perfect balance of carbon dioxide (CO2) around your plants, you're giving them the essential ingredient they'll need to perform photosynthesis. More CO2 means more photosynthesis and more photosynthesis means your plants will grow more. So by improving the air circulation for your plant, you're helping your plants grow more quickly. Who could've thought?
But that's not all! Good air circulation also plays an important role in maintaining the ideal leaf temperature. This helps protect the precious chlorophyll (small batteries that store energy from sunlight) that plants rely on for photosynthesis.
Talking about temperature, let's see how airflow can improve the temperature regulation abilities of your plant!
Regulates Temperature
In the previous section, we learned that good airflow plays a role in controlling the temperature of your plant's leaves. It helps to prevent overheating, which can become a problem, especially in spaces without air conditioning or ventilation. Keep in mind, that this is mostly an issue during the summer.
The leaves of your plants help to control the temperature of the plant. They do this through a process called transpiration, which is like plants sweating. When water inside the plant evaporates from the leaves, the plant cools down. This is important to stop the plant from getting too hot when it's sunny and warm.
Airflow is very important in this process. When there's enough airflow, it moves over the leaves and takes away the moisture that's been released. This causes more water to be pulled up from the roots to replace the lost water. This cycle helps keep the plant at a consistent temperature.
If there isn't enough airflow, the air around the leaves can get too moist. This slows down the sweating process and the leaves can't cool down as much as they'd like. If it's very sunny or hot, this can cause problems for the plant. It can damage the plant and stop it from growing properly.
So if your plant is in a space that's quite warm, it's a good idea to provide a gentle breeze to help the plant cool down.
Reduces Pest Infestations
At the beginning of this plant care guide, we've learned that air circulation helps to prevent diseases. But it also helps to prevent pests! Pests love indoor spaces because they are cozy and warm, making them the perfect place for them to lay eggs and spread quickly.
But there's good news! You can disrupt their lifecycle and create a less inviting environment for them by simply improving airflow. Airflow helps to reduce pest infestations in several ways.
Firstly, many pests such as spider mites and aphids thrive in warm, stagnant air. These pests find it easier to settle, breed, and spread in environments with still air. Good air circulation disrupts these ideal conditions, making it harder for them to settle in.
Secondly, good airflow can help prevent the buildup of excess humidity that many pests love. High humidity can also lead to mold and fungus growth, which can attract even more pests. By circulating the air and reducing humidity levels, you create a less inviting environment for pests.
Lastly, stronger airflow can, quite literally, blow away small pests and insects, making it difficult for them to land and settle on your plants.
Now that we've looked at 5 different ways that air circulation and airflow can help you to keep your plants healthy, let's look at how we can provide better air circulation and better airflow for our plants. You'll see that it's much easier than you might think.
How do you provide good air circulation for houseplants?
Providing your plants with better air circulation and, when needed, better airflow is quite simple. This is what you can do!
Open a window
The first way is to place your houseplants near open windows or doors, where they will naturally receive a gentle breeze. Make sure to only do this in the spring and summer though, as the temperature changes in the fall and winter will be too extreme and could cause your plant to get stressed.
If you don't have space near a window that can be opened, you can also place your plants away from the window while it's open. The plant will still benefit from the improved air circulation in the room.
Use a fan
Another great way to improve airflow, but also air circulation is to use a desk fan or a ceiling fan on a low setting. This helps the air in the room to circulate and stay in motion. If you're using a desk fan, make sure to keep it at a distance from your plants, because a gentle breeze is all the plant needs. We're not trying to create a storm and accidentally dry out the plant from too much transpiration.
Rotate your plant
The next way you might be familiar with, but for a different reason: rotating your plant. You might already do this to expose all sides of your plant to an even amount of sunlight, but this also helps to evenly expose your plant to air circulation.
Regularly prune your plant
And lastly, you can improve the air circulation around your plant by regularly pruning dead or damaged leaves from your plant. This opens the spaces around your plant's leaves and helps each leaf to transpire more effectively. Just be sure to never prune more than 1/3 of your plant, otherwise, this could cause the plant to dry out too quickly.
Conclusion
In conclusion, taking care of your houseplants is more than just watering and giving them sunlight. One important part that many people overlook is the need for good air circulation. This has several benefits that you should know about. It helps prevent diseases and keeps pests away. Plus, it helps regulate temperature and boost photosynthesis.
So, how can you make sure your plants get enough air circulation? It's quite simple! You can open a window, use a fan, rotate your plant, or prune it regularly. Whether you're new to plant parenting or have been doing it for a while, these strategies are easy to incorporate into your routine. With these tips in mind, you'll create an environment where your houseplants can thrive.
