Many of the most popular houseplants out there originally come from tropical regions, meaning that they can sometimes struggle with the lack of humidity in a home environment. If you want your plant to be as healthy as possible, it’s important to get the humidity right. There are a few different ways in which you can adjust the humidity for your plant, but, before you begin, you need to first understand how much humidity your plant actually needs.
Although humidity requirements vary depending on where your plant comes from, the average home has a humidity of around 20%, or even lower when indoor heating or cooling systems are used. To work out how much humidity your plant needs, you will need to know a little more about its native environment.
Plants that come from the tropics or rainforest regions, such as the Monstera, can sometimes need as much as 90% humidity, whereas those that come from the desert, such as the ZZ Plant, only require around 30% humidity. Most other plants fall somewhere in between the two, with 60% usually being a happy medium.
If your plant is lacking in humidity, you may notice that the edges of the leaves are turning crisp and brown. On the other hand, if your plant is in an environment that is too humid, it will start to rot.
Humidity is difficult to get right, but if you know that you need to give your plants a little more, there are a few different ways in which you could go about doing this.
One of the easiest is to mist the leaves of your plant, as well as the air around it. However, this water quickly evaporates, meaning that you will need to do this several times a day for it to really make a difference. The downside to this is that all of that water on your plant’s leaves could cause fungus spores to germinate.
Grouping your plants together can help raise humidity levels, since plants release moisture as they transpire. Another way to create a more humid microclimate would be to fill a tray with gravel, before adding in some water, making sure that the stones at the bottom of the tray are in the water, but the top layer is dry. Then, sit your plant on top of the dry stones - as the water evaporates, your plants will receive extra humidity. Just be sure to keep the tray constantly half-filled!
If you’ve got a humidifier, then this is something else that could help, as could simply moving your plants to a more humid room in your house, such as your bathroom or your kitchen.
Proper humidity levels are key when it comes to keeping your plant healthy, so spend some time working out exactly what your plant needs.
