How Often Do You Water A Bonsai Tree
Although watering a bonsai plant once every 2 to 3 weeks is alright, it also depends on the type of soil and container you are using. The container you will use for potting the bonsai must be well-drained to stop overwatering and clogging.
If the bonsai container has poor drainage, the water will clog into the soil and may rotten the roots and stems of the tree. Next, the soil you will use for the bonsai plantation must be drainable too. The soil’s texture must drain water properly and feature homogenous properties.
Know your bonsai tree species:
Not all bonsai trees will need the same amount of water. Hence the watering frequency for bonsai plants will vary depending on their species. For instance, succulent bonsai species come from arid and drier parts. So, they will need less watering.
However, tropical trees such as willow will require more water. So, for these trees, you need to increase the watering frequency.
Understand the growth period:
As a thumb of rule, bonsai trees need the most watering during their growth period. It means you may need to water them more during summertime and spring season. But when they enter the dormancy period, they will slow down the growth too.
Therefore, during the dormancy period, bonsai trees will need less water. It means you have to slightly increase and decrease the bonsai tree watering frequency depending on their growth period.
Picking the right soil:
When it comes to the bonsai tree watering frequency, choosing the right soil is also important. If the soil lacks a drainage facility, the water will not drain and clog in the pot. Thus, it will damage the roots of the tree.
This is the last thing you would want for the bonsai tree. Hence, ensure that the soil for the bonsai tree is highly drainable and free of any gravel or bits right at its bottom. On top of it, you have to maintain the bonsai tree repotting schedule tightly to allow the soil to drain properly.
Choose the right bonsai pot:
Once you have sorted the soil of the bonsai tree, next focus on the container itself. It is seriously important since the container must be effectively draining and holding the bonsai tree without any clogging issues.
If the pot retains the water or blocks the drainage system, it will rot the tree’s roots. You may look for the following points while choosing the right container for bonsai:
- The container must drain empty when it is empty. If you see the water getting stuck or clogged even in an empty state, you must leave the pot and look for another one.
- Look at the drainage holes in the pot. There should be adequate holes at the bottom of the pot, and their size should be around 10mm to 20mm. But it must not be less than 10mm as smaller holes can’t drain the container properly.
- You should pick a bonsai tree container with feet at its base. The feet help to lift the pot a bit, and so it improves the drainage system.
When you have the right soil and container for the bonsai plants, the standard watering frequency of once every 2 to 3 weeks will be perfect. However, you have to avoid overwatering and choose the right watering can or hose for a comfy watering session.
But before we get into these, let’s check the bonsai tree watering techniques first.
Techniques For Bonsai Tree Watering
You can’t just start watering the bonsai plants following your wish and hope the tree will strive to grow to a beautiful piece of artwork. Instead, you need to focus on it and pay attention to the proper watering tricks for a bonsai tree.
Ensure the right soil mixture:
We have already described the importance of choosing the right soil for bonsai trees. So, it’s time to take the discussion further. When choosing the soil mixture for bonsai, ensure that it has proper drainage, which may come through different materials.
Experts suggest that the right soil mixture for bonsai should contain pumice, lava rock, and Akadema. The ratio can be anywhere from ½ to ¼. Nonetheless, choose a different soil mixture that retains the water for an extended period if you continuously fail to water the bonsai timely.
Avoid routine watering:
The idea of watering the bonsai plants routinely may seem tempting and easy to follow, but it is not effective. Each bonsai tree has different watering needs, and so you must avoid a routine to water them for their healthy growth.
It is better to observe the soil dampness and water each plant when they require watering. Also, it helps the bonsai plants to soak the water better.
Watering when the soil starts drying is the best thing:
You should check the dryness of the bonsai soil to find the perfect time for watering them. Ideally, you should water the trees when the soil starts feeling a bit dry but not entirely dry. You can insert your finger inside the soil to feel the dampness and determine whether or not it needs watering.
Thankfully, there’re three ways to determine the dampness of bonsai soil for the perfect watering for bonsai planters.
Techniques to Determine Soil Moisture Of Bonsai Tree For Watering
The soil of the bonsai tree must not get dry entirely. Hence, you need to find a way to check the dampness of the soil and regulate the watering frequency with perfection. But you may ask, “How do I determine the soil moisture and dampness for bonsai trees?”
Well, check this not one but three suggestions:
The finger method:
The finger method is perhaps the oldest and yet the most effective way to check the dryness of the soil, be it for bonsai or any plants that need watering.
Insert your finger about 1-inch or 20mm deep inside the soil and feel the dampness. If the soil feels too dry, it’s time you water the trees. However, this technique doesn’t apply to all bonsai species. For instance, succulent bonsai trees strive in dry soil. So, you have to know about the bonsai plant watering needs as well.
Use a chopstick:
Alternatively, you may use a wooden chopstick to find the dryness of your bonsai soil. You can use any chopstick that you have previously used for eating noodles. Carefully insert the chopstick about 1-inch to 2-inch deep inside the soil.
Ensure that you don’t hurt the bonsai roots. Leave the chopstick inside the soil for 5 to 10 minutes to absorb the moisture properly. Then, take out the chopstick and check it. If it gets darker or you find water soaked into it, there’s enough moisture in the bonsai soil. So, you can wait for a couple of days before watering it.
If the chopstick color doesn’t change or is void of watermarks, the soil is dry. So, you should water it adequately ASAP.
Use a soil moisture meter:
Both the finger and chopstick will give you an approximate idea of the moisture level of bonsai tree soils. If you want the most accurate readings, you can use a soil moisture meter. It not only frees you from guesswork but also stops under or overwatering the bonsai plants.
So, the soil moisture meter can be extremely valuable for beginners especially. The meter has readings from 1-10, mostly with 1 being the driest reading and 10 being the dampest reading for the soil. So, the lower the reading, the faster you should water the bonsai soil.
For this, insert the long probe of the meter into the soil and check the readings. If the reading is below 4, you should immediately water the soil. If it is between 4- 7, you can wait for a couple of days before watering the soil.
If you wonder how to get the best soil moisture meter, here’re our top three suggestions:

Stop Overwatering Your Bonsai Trees:
Most beginners are concerned about drying out their new bonsai trees. Thus, they end up overwatering the plants. This can be lethal for the bonsais if not identified timely. Hence, we suggest you check the wetness of the soil daily.
If you overwater the soil, it will constantly feel wet. But a properly watered soil will drain out and feel less damp as the day progresses. The best thing is to use a soil moisture meter to find the right wetness of the soil and apply water accordingly.
If you overwater the bonsai plants, they will rot the roots. On top of it, overwatering may block the oxygen from reaching the tree roots, eventually turning the leaves yellow. Also, the branches will grow weak, and finally, the stem will die.
So, be aware of it and follow our suggestions of watering bonsai trees once every 2 to 3 weeks adequately for their proper and healthy growth.
Here, we will end our discussion on how often do you water a bonsai tree. Ideally, watering once or twice every three weeks will work fine. However, during the growth time in summer and spring, you may need to increase the watering frequency a bit. On the other side, lower the watering frequency during the dormancy period.
The best way is to use your finger or the moisture meter to measure the dampness of the soil and water the bonsai plants accordingly.
