There is a reason why not all plants thrive in deserts. One of them is that there are scanty resources such as water. Therefore, plants need water, both in the air and in the soil or medium in which you are growing them.

Is humidity good for plants?

Firstly, you should know the optimum humidity for plants recommended for a certain plant. Some plants need more humidity and some need less. Read up some botany information!

Secondly, always remember that high humidity for plants is bad for your home, your furniture and even your health. Too high humidity is not good for them. It has to be just the right percentage.

Thirdly, all that you wanna do is create a habitable environment for the plants, same as they would find outdoors in their natural habitat. To clarify this further, a cactus plant would need less humidity than an orchid which requires a humid environment to thrive.

What is the right humidity for plants?

Indoor plants need different humidity levels. For example, if you have a desert plant, it may require humidity levels of 40 to 50%.

Are you considering getting a humidifier for tropical plants? Indoor tropical plants need a humidity level of between 50 to 60%. However, some plants may need even more than 60%. However, if you increase the indoor humidity level higher than 60%, it will damage your paintings, walls and it can cause mold.

Signs that you need more humidity for plants

One of the ways for how to increase humidity for indoor plants is to get a humidifier for plants. However, do not crank up the humidity yet. First, you need to see that truly, your indoor plants need some humidity. Here are the main indicators to watch out for before you increase humidity for plants:

1. When your indoor plant leaves start developing brown edges

One surefire sign that your plants need more humidity is when they start to develop brown edges on their leaves.

According to this site, when plants start to develop brown edges on their leaves, it means they are not getting enough water. Thus, you can consider increasing the watering frequency as you also consider cranking up your humidifier.

Be careful not to make the humidity too high. You see, browning on the leaves can be caused by other factors as well. For example, if the soil has too much salt content, the leaves can start turning brown.

Therefore, use a hygrometer to check the humidity level in the room where you are growing your plants. If humidity is between 40 and 60 percent, it is fine for plants. You can therefore check out other possible causes of brown edges on the leaves.

2. When plants wilt – When should I use a humidifier for my plants?

When should I use a humidifier for my plants? Definitely, it is not best to wait for plants to start wilting so that you can tune on the humidifier.

All the same, check out for signs of wilting in your plants. But first, what really causes wilting and how is it connected to dry air?

How low humidity affects plants

When you water your plants, they take it through the roots. Then the plant will lose the water as vapor in a process known as transpiration. I guess this is a way to try and keep the air around the plant as humid as should be. It is the plant’s cooling mechanism.

Therefore, since the plant is trying to regulate the area around it, if the air is too dry, the process of transpiration will be reversed. Therefore, instead of opening its stomata to let out transpiration gases and water, it closes them! Thus, it chokes on its own gases and vapor, and it starts failing.

Can you then water the plant much more than you need to? Sorry, but this too will not prevent wilting. The most helpful thing would be to turn on the humidifier and increase the level of humidity in the grow room.

When you water the plant more than necessary, you will waterlog the roots and this hinders their absorption ability.

Low humidity causes stunted growth

Another thing that you need to check is when the flowers fall off as soon as they open. Check also whether the buds fell off just as they were about to open.

How high humidity affects plants

Considering the effects of low humidity that we have discussed above, you might be tempted to make the air more humid than necessary.

Bad idea!

Knowing how to create humidity for indoor plants requires you to know the right level of humidity for your indoor plants.

Let me explain why. When the plant senses too much humidity in the air, it does not take enough water from the medium (soil or other).

This also means that it does not take up enough nutrients from the surrounding, which eventually hampers its growth. When the plant lacks important nutrients such as iron and calcium, it becomes emaciated and it will not flower well.

The solution – When should I use a humidifier for my plants
