How To Create Your Bonsai Soil At Home

Soil is much more than just a potting soil for bonsai plants. It’s an essential part of creating healthy, vibrant landscapes that are full and rich with life – from the ground up!

There are a few things you need to consider when creating your bonsai soil mix.

  1. The first is the type of tree you are growing. Some trees thrive in well-draining soils while others prefer moist soils.
  2. The next consideration is the climate where you live. If you live in a hot, dry climate, you will need to create a soil mix that drains well and retains moisture. If you live in a cooler, damper climate, you will need to create a moister mix.

Once you have determined the type of tree and climate you are dealing with, it’s time to start creating your soil mix!

There are a few things you need to know before you create your bonsai soil mix. The ingredients in bonsai soil are a mixture of different materials, including pumice, akadama, lava rock, fine gravel, and organic potting compost. This creates the perfect balance to promote healthy roots as well as an aesthetically pleasing appearance for your tree!

To maintain the perfect bonsai soil, it is important to make sure that your tree’s potting mix has a pH between 6.5-7 which will keep its nutrients from becoming acidic or basic.

This means that if you are creating your own soil mix, you will need to test the pH of your soil before adding any fertilizers. You can use a simple kit that is available at most garden stores, or send a sample off to a lab for testing. If you are sure of your mix already, you can also just take a sample of the soil to your local garden center.

Components of a Bonsai Soil Mix

Bonsai mix is typically separated into two categories, organic and inorganic. The difference between organic and inorganic is based on water retention. Both organic and inorganic have grit. The mix becomes dry due to this gritty nature, which allows for excess water to drain from the mixture.

Organic: Organic components of bonsai soil include peat, moss, and bark. These materials hold onto water to help the tree sustain moisture. This is perfect for trees that require more moisture to survive.

Inorganic: Inorganic components of bonsai soil include lava rock and akadama clay. These ingredients allow for the soil to dry out more quickly so that the tree will not become overwatered. This is perfect for trees that thrive in well-draining soils.

When creating your bonsai mix, it is important to use a variety of materials to create balanced soil. By using both organic and inorganic materials, you are allowing for the perfect amount of water retention to keep the bonsai soil at just the right humidity.

Why is the Organic Component Important?

The organic component of bonsai soil is very important because it provides the tree with nutrients. The organic ingredients that are used in bonsai typically come from peat moss, sphagnum moss, and aged bark.

This aquatic plant has many beneficial properties for your tree. It allows for good water retention which will help your trees retain moisture. It also provides your trees’ roots with beneficial nutrients that promote healthy growth.

Peat moss is another aquatic plant that holds onto water which makes it perfect for bonsai soil! The sphagnum moss is the last organic component you need to create the perfect bonsai mix. This moss provides an acidic pH which is perfect for bonsai trees. It also helps to retain nutrients and moisture in the soil mix.

Aged bark is the perfect organic component for your bonsai soil because it is rich in nutrients! The bark has been aged for some time so that all of the beneficial properties are released. This ingredient will help to promote healthy root growth as well as a healthy appearance.

Why is the Inorganic Component Important?

The inorganic component of your bonsai soil mix is important because it helps to create well-draining soil. The ingredients, such as lava rock and akadama clay, help to absorb excess water and allow the soil to dry out quickly.

Lava rock is a great inorganic ingredient for your soil mix because it is porous. This means that it will absorb water and release it back into the soil slowly. This is perfect for bonsai trees that require well-draining soils!

Akadama clay is another great inorganic ingredient for your soil mix. This particular clay absorbs water very well and releases it back into the soil slowly. This is perfect for promoting healthy root growth without overwatering your bonsai!

What are the Advantages of Using a Bonsai Mix?

There are several benefits to using a bonsai soil mix. Some of the most beneficial attributes include:

  • Promotes healthy root growth – Using quality ingredients for your bonsai soil can promote healthy root growth. By using organic and inorganic ingredients, you are providing your tree with everything it needs to grow healthy roots.
  • Allows for well-draining soil – The inorganic ingredients that are used in bonsai soil mix allow for the soil to dry out quickly. This is perfect for trees that do not like wet soils!
  • Retains moisture – The organic components in bonsai soil will help to retain water and keep the soil at just the right humidity. This is perfect for trees that require high levels of moisture!
  • Increases aeration – Using a bonsai mix allows for better air circulation within your tree’s roots. This means that your tree will receive more oxygen which is essential for healthy growth.
  • Saves time – Creating your bonsai soil mix is a great way to save time. You can buy all of the ingredients that you need online or at your local garden store.

There are many benefits to using a bonsai soil mix! By using quality ingredients, you are providing your tree with everything it needs to grow healthy roots.

Why is Water Retention an Important Factor in Mixing Your Bonsai Soil?

When creating your bonsai soil mix, it is important to consider water retention as one of the main factors. A good mix will allow for consistent moisture levels in the soil, while also providing drainage when needed. Too much or too little water can be damaging to your bonsai, so it is important to find the right balance.

  1. One way to increase water retention in your soil mix is to add organic matter. This can be in the form of compost, peat moss, or any other organic material. The organic matter will help to hold on to water, keeping the soil moist for longer. In addition, it will also provide nutrients and minerals that are essential for the health of your bonsai.
  2. Another way to increase water retention is to use a pot with a wide base. This will help to keep the soil moist by preventing it from drying out as quickly. It is also important to make sure that your pot has drainage holes so that excess water can escape.

If you live in an area with high humidity, you may not need to worry as much about water retention. However, if you live in a dry climate, it is important to take into account the amount of water your soil mix will hold. By using a mix that retains water well, you can help to ensure that your bonsai stays healthy and thriving.

Why is Proper Aeration an Important Factor in Mixing Your Bonsai Soil?

Aerating is an important action when mixing Bonsai soil because it allows air to connect the particles of the soil’s components. The particles will hold better when one is made more porous by aeration.

When mixing Bonsai soil, it is important to ensure that the particles of the larger, inert component (typically Akadama, Turface, or calcined clay) and of the organic components (typically pine bark and peat), are well aerated. Thorough aeration will make the particles more porous and allow them to hold water and nutrients better.

Aeration can be achieved by hand or machine. Hand mixing is typically done with a rotating steel drum (such as the Wilma Mixer). The drum should move slowly, covering all of the ingredients during each revolution to ensure thorough aeration. Machine mixing produces excellent results every time, but it requires more time. The extra time is well worth it for a professional or serious enthusiast.

Machine mixing ensures thorough aeration of the soil components and will provide excellent results every time.

What’s Needed When Making Bonsai Soil?

To make a bonsai soil mix, you will need potting soil that drains well, some organic matter like compost or peat moss, and perlite or sand.

If your bonsai is indoors, you will also need to add some moisture-retaining ingredients like humus or a wetting agent. You can use a premade mix or do what many bonsai artists do and create your own from scratch.

How to Make a Bonsai Soil From Scratch

If you are making bonsai soil from scratch, follow these steps:

1. In a wheelbarrow, add some potting soil and perlite and mix them (perlite will increase the soil’s ability to drain and air space). For healthy outdoor bonsai plants, use a 50:50 mixture.

2. Add some organic matter like compost or peat moss if desired; about 20% is sufficient. You can also add at this time whatever fertilizer or wetting agent you like.

3. Mix everything well and store it in a covered container until you are ready to use it.

Why is Drainage an Important Factor in Mixing Your Bonsai Soil?

Drainage is an important factor in your bonsai mix for a few reasons.

  1. First, if the soil can’t properly drain, water will sit in the pot and rot the roots of your tree.
  2. Second, good drainage allows air to circulate the roots, which is necessary for healthy growth.
  3. Finally, proper drainage prevents the salt build-up that is toxic to your tree.

Sample Steps to Making Your Bonsai Soil

Gather all the components you need, an organic compost, Lava rock, and akadama. This is to make the bonsai soil mix simple for you.


  1. Have medium-sized granules of your akadama, lava rock.
  2. Next, you must screen both your organic compost and your akadama properly.
  3. Also screen the laval rock.

That’s it!

Common Mistakes In Preparing a Bonsai Soil Mix

There are a few common mistakes people make when preparing a bonsai soil mix.

1. One of the most common mistakes is using potting soil or garden soil in their mix.

  • Potting soil and garden soil are not meant to be used for bonsai, as they do not provide the right balance of nutrients and drainage needed for healthy bonsai trees.
  • Potting soil and garden soil (topsoil) do not contain enough nutrients and organic matter for bonsai and should be avoided in favor of a bonsai mix.
  • Potting soils especially should be avoided as they often contain slow-release fertilizers meant for indoor, pot-grown plants; these fertilizers will burn the roots of a bonsai if used over an extended period.

2. Another common mistake is using too much soil or not enough soil in their mix.

The right mix depends on the size and type of pot the tree is planted in, so it’s important to do your research before starting to mix your soil.

Having too much soil will affect the drainage of the pot and could lead to root rot while having too little soil will not provide enough nutrients for the tree.

3. Using soil with aggregates instead of sand.

Double-check what kind of soil you have before you start mixing. If your soil has a lot of aggregates in it, you’ll need to add sand to help with drainage.

Aggregates can affect the overall stability and look of a bonsai, so avoid using them if possible.

Using aggregates in your soil mix will also make it harder to water and fertilize your tree, as the aggregates will hold onto the water and nutrients.

4. Not using compost in their mix.

A good bonsai mix should always contain compost, as it helps with drainage, nutrient retention, and overall root health.

Compost is a key ingredient in any healthy soil mix and should not be skipped.

5. Not mixing their soil.

While it’s possible to buy pre-mixed bonsai soils, it’s always best to mix your soil to ensure that it’s the right fit for your tree and pot.

Pre-mixed soils often contain the wrong mix of ingredients or too much of one ingredient, which can be harmful to your tree.

Mixing your soil also allows you to customize it to your specific needs, which is important for healthy trees.

6. Not enough aeration.

One of the benefits of using a bonsai mix is that it’s easier to create air pockets in the soil.

These air pockets allow for better aeration and help keep the roots healthy. If your soil doesn’t contain enough sand, you can add perlite or vermiculite to increase aeration.

Good aeration is key to healthy bonsai trees, so make sure your soil mix has the right ingredients to create air pockets.

7. Failing to do artificial feeding.

Even if you have the perfect soil mix, your bonsai will still need to be fed regularly.

Fertilizing a bonsai is important for keeping it healthy and looking its best; without regular fertilization, a tree can start to look sickly and stressed.

There are many different types of fertilizers available on the market, so find one that fits your tree’s needs and stick to a regular feeding schedule.

Tips in Caring for Your Bonsai

The bonsai is a miniature tree that has been developed in Japan and China. It is used as an ornamental plant and represents the traditions and culture of these countries. Caring for your bonsai is not difficult, but it does require some basic knowledge and a bit of effort.

  • In order to care for your bonsai, you will need to water it regularly and fertilize it twice a month. You should also trim the tree’s branches and leaves regularly to keep it looking neat and tidy. It is a good idea to repot the tree every year, adding some fresh soil to the pot. You can then fertilize it again and turn it slightly so that it will continue growing toward the sun.
  • In order to water your bonsai, you should pour water into the bowl at its base until it begins draining from the holes in the bottom of the pot. Be sure to pour out any excess water, as you do not want the roots to sit in water for an extended period of time.
  • Fertilizing your bonsai is easy – just sprinkle some fertilizer onto the soil at its base and then water it in. You can find bonsai fertilizer at most plant shops.
  • When should you repot your bonsai? This depends on the type of tree you have and how large it is. You can tell that your tree needs to be repotted when its roots begin to break out of the pot or if there are too many roots compared to leaves and branches. At this point, remove as much of the old soil as possible and then replant it in a pot that is one size larger. Add fresh soil to the pot and then water it in well.
  • Your bonsai should be positioned so that it will receive plenty of sunlight. Place it near a window where it will get at least four hours of direct sun each day. If you cannot put your bonsai in a spot that gets enough direct light, you can supplement the sunlight with an artificial source by placing it under grow lights for twelve hours each day.
  • A general rule of thumb when caring for your bonsai is to not fertilize the tree during the spring and summer months. This will encourage leaf growth instead of root growth, which will weaken the tree. You can begin fertilizing it again in September or October.
  • Before caring for your bonsai, it is important to familiarize yourself with its specific needs and characteristics. This way you will know how much water to apply, when to repot it, and so on.

The process of growing bonsai can be an enjoyable and relaxing activity. It has deep historical roots in Asia, and while you grow your tree, you can reflect on the ancient history of China or Japan.

Final Thoughts on How to Care for Your Bonsai Soil

Bonsai is one of the most popular plants to own. They are easy to care for, can be placed anywhere in your home, and are small enough that they don’t require a lot of attention. The best part is that you can keep your bonsai alive with just a little know-how and some TLC.

One of the most important things to remember when caring for your bonsai is to keep the soil healthy. The type of soil you use will affect the health of your plant, so it’s important to find soil that is right for your bonsai.

There are a few things you should look for when choosing soil to use, such as how much it holds water and whether or not it is nutrient-rich. You will want soil that drains well but also retains moisture, as this type of soil will keep your bonsai from drying out too quickly.

Healthy roots are vital for bonsai because they absorb nutrients from the soil and take in the water that your plant needs to survive. When you choose soil that is not healthy, you may notice that your bonsai’s roots are yellowing or browning, and sometimes even blackening. Your bonsai will need a healthier type of soil so the roots can grow properly and be able to absorb nutrients from around them.

Take note that the overall health of your bonsai depends on the soil, the seed you choose, the pot, and even more factors you must consider.
