Knowing all the factors that determine how much water your Bonsai tree needs will ultimately make it easier when it actually comes to doing it. So let us delve a little deeper into these factors. But, first, make sure to ask yourself these simple questions.

What Is a Bonsai Tree? 

So, what actually is a Bonsai tree? Bonsai trees is a term that we use in English to describe any tree that can be grown in a pot. 

These trees’ can be of any species or type, whether deciduous or evergreen. The species you are growing will determine how much water they need, good to know what you’re dealing with.

What Soil and Pot Are You Using?    

The soil you plant your Bonsai in is extremely fast draining because it doesn’t retain an awful lot of water. Therefore, it is always good to know how much soil you have to support your tree. 

The amount of soil you have is determined by the size of your pot. Obviously, the smaller the pot is then the less soil it can hold; on the reverse, the bigger the pot, the more soil.

The smaller pots will need watering a couple of times a day, and the bigger ones can get away with a few times, every couple of days or so. 

When is Your Bonsai Active? 

No, we don’t mean when your tree likes to walk or go on a jog; this is when your tree is growing. This growth stage is probably one of the most significant factors in deciding how much water your tree needs. 

Trees that have entered their dormant stage in their cycle will require less water than when actively growing. 

Keep an eye out for fruits and flowers, as flowering plants/trees need more water to support themselves. 

Where Is Your Bonsai Located?

You should ask yourself is where you are keeping your Bonsai tree. Your tree’s location will have a pretty significant impact on how much water your tree will need. 

An example of this is if your tree is in the sun during the height of summer, then your tree will need more water. However, when you compare this situation against a tree in the shade or undercover, your tree won’t dry out as fast. 

Take a look at the location you are in as well. Are you in a hot climate or a cooler climate? If your tree is kept outside, has it rained recently? All things need to be taken into consideration when finding out when to water.

What Are Good Techniques for Watering Your Bonsai? 

Why Are Bonsai Pots So Expensive

There are many ways of watering plants, but there are few great ones for watering Bonsai trees. 

The first method you can use to water your tree is the conventional watering method. The method you should all be familiar with. Watering from the top of the plant. 

This method either requires a hosepipe or any watering can, ideally with the shower attachment/setting. This technique creates and simulates the falling rain, as it provides either a gentle stream of water or the shower effect. 

This way, hold your hose or watering can over your Bonsai for around thirty or sixty seconds, just enough water to saturate the soil. 

The second method for watering a Bonsai tree is what we mentioned earlier. Watering your tree from the bottom. 

In this method, you place your tree in a container or shallow dish of water. Just make sure that the water reaches the rim of the pot your tree is in. By using this method, you can leave your Bonsai in the water for a long time.  

In fact, you can leave it anywhere from a few minutes to half an hour, just sitting in the water. So, the short amount of time your plant is submerged won’t damage or affect your plant. Just keep half an eye on how long you leave it in there for; they don’t like spending too long in the water. 

Whichever method you pick, whether one described here or elsewhere, they all will work as effectively as each other. However, you may find that you discover you prefer one method over the other when it comes to watering. 

In this case, stick to the one you prefer. Specific methods may work better depending on the size of your specific plant; for example, bigger trees may be easier to water from the top. 

Whereas smaller trees may be easier to put into a container. Just remember, it is a lot easier to underwater a Bonsai tree than it is to overwater one

We all make mistakes, especially when it comes to caring for our Bonsai trees. Here are some common mistakes and see how to avoid them. 

Forgetting to Water 

This should not need much explanation as to why it is a mistake to forget to water your bonsai tree. Put simply, the roots can dry up, and the tree dies. Make sure you stick to a routine. You can even set reminders up on your phone, so you won’t forget. 


This mistake can be just as costly as not watering your tree. If your soil is too wet, the roots can rot and die, causing your tree to die in the process. A way to avoid this is to adopt a good care routine. Make a plan and stick to it like glue.

Being Too Over the Top  

We know sometimes we can get a little bit carried away when caring for your Bonsai tree. Whether that is watering your plant or pruning it. Don’t forget your tree can not change as quickly as you can snip, so develop an excellent simple routine will help stop any eagerness on your part. 

So, what happens if you don’t think you have made any of these mistakes with your own Bonsai tree? Is it still not looking its best?

Well, in that case, it may have become infected with a pest or other illness. Have a look at the leaves of your Bonsai for any sign of insects, and remove the tree from its pots and have a look at the roots. 

If you see something you are sure doesn’t look right, take it to a local expert and get their advice. 

In Conclusion 

One of the most essential things about caring for a Bonsai tree is making sure you give them enough water. Depending on your specific tree dictates how much water you should give.
