Growing bonsai trees present many challenges, and this is especially true if you’re trying to grow them in suboptimal environments. Now, many of you may be surprised to know that one of the most difficult environments to grow bonsai trees is actually indoors. In fact, some bonsai species cannot survive indoors as they tend to just weaken and die.

Even with the right species of the plant, growing them indoors and keeping them alive can still prove to be quite challenging. This is doubly true if you’re a new grower. To help you out, we’ve prepared a short guide on how to grow bonsai trees indoors. If this something that you want to learn about, read on for a beginner’s guide on keeping bonsai trees alive indoors!

Provide Sufficient Light

The first thing you have to address is lighting. Just like any plant, bonsai trees need sufficient lighting to thrive. What makes this so difficult is that the lighting indoors is of a much lower intensity as compared to the outdoors. For this reason, keep in mind that insufficient lighting leads to poor growth, which can eventually lead to the demise of the plant.

So, how do you deal with this problem? Well, the solution is rather simple. All you have to do is use fluorescent light or high-intensity lamps to make up for the lack of lighting indoors. This should effectively help make up for the lack of lighting and will go a long way in helping the plant thrive in an indoor environment!

Maintain High Humidity

Other than lighting, you’ll also need to keep an eye out for the humidity levels because it will quickly cause the demise of your bonsai. Room heating and air conditioning are both factors that affect humidity. 

To maintain high humidity levels, put your tree on a humidity tray that’s filled with water. If you don’t have a humidity tray, you can just mist the bonsai a few times throughout the day. Increasing the air circulation by opening your windows will also help keep the humidity up and ensure your plant’s survival.

Water and Fertilise Properly

Now, keep in mind that we said mist your bonsai and not water it. This is because you only want to water your bonsai if it is dry. You can determine its dryness by either using a moisture meter or checking manually with your finger, and the same can be said about fertiliser. You don’t need to go overboard with the amount of fertiliser to use, but it is a requirement if you want to grow bonsai indoors. 

Control the Temperature

Lastly, remember that there different types of bonsai that thrive in different climates. Tropical trees require high temperature to thrive. They’ll do fine at room temperature, but you don’t really want to put them in a colder environment as they will surely not survive. 

On the other hand, the Mediterranean and semi-tropical species can thrive in colder temperatures. Just be sure to understand what species of bonsai you’re growing and the condition that it requires to grow so that the tree won’t die prematurely!


We hope this guide proves to be helpful when it comes to helping you grow bonsai trees indoors. Growing these plants is all about paying attention to every little detail.
