The Japanese Kingsville boxwood bonsai tree (Buxus microphylla ‘compacta’) is a tree that is native to Japan and it grows beautiful flowers during spring.
It has the smallest leaves of all boxwood varieties and this is what makes it a great tree for bonsai enthusiasts and that is the reason I have created this Japanese Kingsville boxwood bonsai for sale article.
This is an evergreen bonsai which means it will keep its leaves all year long so you can admire the beautiful bonsai you help create all year long instead of only being able to admire it during the seasons that trees have leaves on them.
The Kingsville Boxwood is pretty easy to keep healthy and thriving as an indoor bonsai tree so if you are a beginner or even an expert to this hobby then this is a great choice and why I recommend you do buy a Japanese Kingsville boxwood bonsai regardless of your experience.
Things that make the Japanese Kingsville boxwood a great bonsai tree:
- Small leaves make it easy to shape into a bonsai style
- Evergreen bonsai so you can admire it all year long
- Flowers during spring which adds to its beauty
- Slow growing so you won’t have to re-pot it often

Can boxwood bonsai be grown indoors?
A boxwood bonsai tree is a very hardy variety of bonsai which will allow you to get your bonsai to thrive in almost any conditions.
So, yes a boxwood bonsai can be grown indoors, and not only can it be grown but it can be grown into a thriving bonsai specimen.
When you have a boxwood bonsai that you are growing indoors you just have to make sure that you feed it enough water as bonsai do dry out kind of quickly because of the small pots they grow in, this can be especially problematic if you have a radiator at the window your bonsai is positioned at.
If having bonsai at your window isn’t the vision you have and you would prefer to have it as a decoration on say the middle of a coffee table then that is no real problem.
In the wild boxwoods grow under large trees so they can thrive when they do not have direct sunlight, a bit of sunlight will obviously help but if you have a bright sunlit room then your boxwood bonsai should still do ok.
How much light does a boxwood bonsai need?
Boxwood bonsai trees really don’t need to have direct sunlight all day every day because in the wild they thrive under larger trees.
Boxwood bonsai actually will do better in conditions that mimic the wild so if you can create partial sunlight conditions that would be more ideal than having it in the sun all day long.
When it comes to the science of how much light a boxwood bonsai needs then 800 Lux is all it needs which makes it possible to grow in any room with a window, the sun doesn’t even need to shine in the window but as long as the room gets bright enough your boxwood will do just fine.
If you do want to grow a boxwood bonsai but you fear you won’t be able to get it enough light you could always use a budget LED grow light for a few hours per day and that should be enough to make your boxwood thrive
What is the best fertilizer for a boxwood bonsai?
Because of the small pots and minimal amount of soil that gets used when growing bonsai, it is inevitable that your bonsai tree will eventually drain the soil of all the healthy nutrients that are required to sustain a healthy bonsai.
Using a fertilizer on your boxwood bonsai or any other bonsai is essential if you want to have success.
The best option is to use any sort of specialist bonsai fertilizer and there are two main options you should consider and they are:
- Liquid fertilizer – a liquid fertilizer is probably the most popular type of fertilizer for bonsai. They come in a concentrate so you just dilute it in the water you feed your plant. You should follow the instructions when you buy fertilizer but generally, they recommend you apply fertilizer every 1-2 weeks.
- Slow Release Fertilizer – there are a few different types of slow-release fertilizers but they all have the same advantages. Whether you use pellets or a fertilizer cake, you simply add them to the soil then when you water your bonsai the fertilizer will slowly be released over time. Normally you only have to add more slow-release fertilizer every 2-3 months
How often should you trim a boxwood bonsai tree?
You only need to trim your boxwood bonsai tree once per year and the only time that is recommended to carry out this task is during springtime.
When you chop the ends of branches it actually encourages fresh growth so you definitely don’t want to be pruning your bonsai any time after mid or late summer.
If you prune your boxwood too late in the season your tree may not have enough time to recover before winter sets in and it could potentially lose its leaves or become unhealthy in general due to stress.
If during the summer you notice any branches or leaves that are irritating you by growing in the wrong direction or are just growing too long then it’s ok to trim them off, you just want to avoid any major pruning apart from once per year during springtime.
How do you prune a boxwood bonsai tree?
When you are giving your boxwood it’s annual prune I recommend you mark where the front of the tree is so you know what side to make the most aesthetically pleasing.
Always start your pruning at the bottom of your tree and work your way up.
When you are creating bonsai there is no exactly correct way to do it as it’s your own vision you are creating so the main thing is to prune it into the shape you want it to be.
- The first thing I do when I am pruning bonsai is to firstly remove any excessively long branches that obviously need to be removed.
- The next stage is to remove any branches or leaves that are growing straight up or especially straight down.
- Now remove any larger branches that are not growing in the shape of your vision. (It’s hard but big branches sometimes have to be removed).
- Finally cut back the leaves to the correct length because it’s bonsai you are creating, not a bush.

How do you shape a boxwood bonsai tree?
To get your boxwood bonsai or any other bonsai into the exact shape you want to achieve may actually take many years so the key thing is persistence and patience.
Pruning your bonsai is the main tool you have when it comes to creating the shape of your bonsai.
The goal of bonsai is to create a mini tree that looks the exact same as a giant tree you would find in a forest in the wild.
Most trees that grow wild don’t have any branches that grow down the way and most branches will grow out sideways and this is what you want to achieve with your bonsai so that it looks like a naturally grown tree.
Apart from pruning, the other main technique to get your bonsai growing in the shape you want is to use wire to force branches to grow at the angle you are trying to achieve.

Traditionally, wire was never used to create the shape of bonsai and it was all done by pruning, however, times change.
There are a few techniques you can use when it comes to wiring a bonsai and there isn’t really a correct way to do it; you simply have to do what works for you.
- Technique 1 – For this technique, you wrap the wire around the trunk of your bonsai as an anchor then wrap the wire around the branch you are trying to change the angle of.
- Technique 2 – the two branch technique, this works if you have 2 branches on opposite sides you want to change the angle of. Wrap the wire around the trunk then coil it around the first branch you want to change the angle of then wrap it around the 2nd branch. You should do this technique with one continuous length of wire.
- Technique 3 – the spring coil technique, this works best for younger branches, simply coil the wire around the branch but don’t do it tightly it should be more like a spring. This method will encourage rather than force the branch to grow in the desired direction.
How do I know if my bonsai needs water?
The easiest way to tell if your boxwood bonsai tree needs water is to check the soil.
If the top layer of soil looks as if it is dry that is a sign you need to water your bonsai.
To check whether the soil in your bonsai pot is dry the easiest way is to simply stick your finger in the soil and if it is dry more than 1.5 cm down then it is time to give it water.
When you become something of an expert it is also possible to tell if your bonsai needs to be watered by simply looking at it, if it looks dehydrated it definitely needs water.
There are also electronic devices you can use to probe the soil and it will tell you if the soil is dry or moist but I find it easier to simply stick my finger in the soil and check how it feels.
How often should you water a boxwood bonsai?
How often you need to water your boxwood bonsai depends mostly on the climate and environment where you are growing it.
Bonsai trees in general are known to dry out pretty quickly because the small pots they grow in aren’t capable of holding very much moisture.
During the summer months, you will more than likely have to water your bonsai every second day or even every single day if you live somewhere with a hot climate.
During the winter months, you should be able to drastically reduce how often to water your boxwood bonsai, just stick to the putting your finger in the soil technique, however, during winter the soil will dry out a whole lot more slowly so you may only have to give it some water once or twice per week.
Can you overwater Kingsville boxwood bonsai?
Yes, it is totally possible to overwater a boxwood bonsai, the exact same as every other potted plant.
Boxwood bonsai like the soil to be damp and not completely dried out however if you keep the soil permanently soaked you will run into all sorts of problems.
The signs that you are overwatering your boxwood bonsai are:
- It starts to wilt and looks generally unhealthy
- Foliage starts to turn yellow starting from the base and spreading upwards
- New growth stops appearing
- The color starts to fade from dark green to lighter green
- The biggest problem is the roots will start to rot
You definitely want to avoid overwatering your boxwood bonsai to avoid these problems.
If you add too much water every so often then that is not really a big problem as you can just give it an extra day or two to dry out before you water it next.
The problem is when you give it too much water long term without realizing you are doing it.
When you give your boxwood bonsai too much water long term then the big issue is root rot because when that sets in you may or may not be able to recover the health of your bonsai, the other signs of overwatering might not appear until root rot has started.
