Bonsai trees are delicate and beautiful, requiring special care to thrive. One essential aspect of bonsai tree care is providing the right nutrients to ensure healthy growth and stunning foliage. While commercial fertilisers are readily available, many enthusiasts prefer to make their own natural fertilisers to avoid harmful chemicals and promote a more sustainable approach to bonsai cultivation.
Creating your own natural fertilisers for bonsai is not only cost-effective but also allows you to customise the nutrient mix to suit the specific needs of your trees. By choosing natural ingredients and following simple procedures, you can provide your bonsai with the essential nutrients they require to flourish.
Organic matter plays a vital role in bonsai fertilising. Composting kitchen scraps, fallen leaves, and grass clippings is an excellent way to generate organic matter. These materials are rich in nitrogen, phosphorous, and potassium – the primary nutrients needed for healthy bonsai growth. You can collect organic matter in a compost bin or pile and allow it to decompose over several months. Once fully decomposed, the rich compost can be used as a top dressing or mixed with water to make a nutrient-rich tea for your bonsai.
Another natural fertiliser option is comfrey tea. Comfrey is a nutrient powerhouse, bursting with potassium, calcium, and trace elements required by bonsai trees. To make comfrey tea, simply harvest comfrey leaves and soak them in water for several weeks. The resulting liquid can be diluted and used as a liquid fertiliser. Comfrey tea is particularly beneficial during the growing season when bonsai trees have increased nutrient requirements.
Why use natural fertilisers for bonsai
Bonsai trees require regular fertilisation to maintain their health and promote strong growth. While there are many synthetic fertilisers available on the market, using natural fertilisers has several advantages.
- Environmentally friendly: Natural fertilisers are made from organic materials and do not contain harmful chemicals. They are safe for the environment and do not contribute to pollution or damage the soil, water, or air.
- Nutrient-rich: Natural fertilisers, such as compost or manure, are rich in essential nutrients that bonsai trees need to thrive. They provide a wide range of macro and micronutrients that synthetic fertilisers may lack.
- Sustainable: Producing natural fertilisers can be a sustainable practice. Composting kitchen scraps or using animal manure are examples of recycling waste and turning it into a valuable resource.
- Slow release of nutrients: Natural fertilisers release nutrients slowly over time, which prevents overfeeding and reduces the risk of root burn. This allows the bonsai tree to absorb nutrients gradually and in a more balanced manner.
- Improved soil structure: Natural fertilisers help improve the soil structure by promoting microbial activity and enhancing moisture retention. This creates a healthy soil environment for the bonsai tree’s roots to grow and develop.
- Long-term benefits: Using natural fertilisers can improve the long-term health and vitality of bonsai trees. They enhance the overall strength and resistance of the plant, making it more resilient to diseases and pests.
In conclusion, natural fertilisers provide several advantages for bonsai trees. They are environmentally friendly, nutrient-rich, sustainable, and promote slow release of nutrients. Additionally, natural fertilisers improve soil structure and have long-term benefits for the health and vitality of bonsai trees.
Types of natural fertilisers
There are several types of natural fertilisers that can be used for bonsai plants. These fertilisers provide essential nutrients needed for the growth and development of bonsai trees. Below are some common types of natural fertilisers:

2. Manure
Manure, both from animals like cows, horses, and chickens, as well as from other sources like sea birds, can be used as a natural fertiliser. It is rich in nitrogen, phosphorus, and potassium, which are vital for plant growth. However, manure should be aged or composted before using it on bonsai trees to prevent burning the roots.
3. Fish emulsion
Fish emulsion is a liquid organic fertiliser made from decomposed fish or fish by-products. It is rich in nitrogen, phosphorus, and trace elements. Fish emulsion is a great source of nutrients for bonsai plants, and it can be easily absorbed by the roots, promoting vigorous growth and overall health.
4. Bone meal
Bone meal is a natural fertiliser made from animal bones. It is rich in phosphorus, which is essential for root development and flower production. Bone meal is particularly beneficial for flowering bonsai trees and can help in enhancing their blooming.
When using natural fertilisers, it is important to follow the instructions and recommendations provided by the manufacturer. It is also advisable to use a balanced fertiliser that provides a mix of essential nutrients for your bonsai plants. Regular and proper fertilisation will help keep your bonsai trees healthy and thriving.
Organic fertilisers for bonsai
When it comes to feeding your bonsai, using organic fertilisers can provide a gentle and long-lasting source of nutrients for your miniature tree. Organic fertilisers are derived from natural sources and contain a wide range of essential nutrients that your bonsai needs to thrive.
One popular type of organic fertiliser for bonsai is compost. Compost is made up of decomposed organic materials, such as kitchen scraps, yard waste, and leaves. It is rich in nutrients and provides a slow-release fertilizer that nourishes your bonsai over time. To use compost as a fertiliser, you can mix it into the soil or sprinkle a layer of compost on top.
Another effective organic fertiliser option is worm castings. Worm castings are the waste product of earthworms and are highly nutritious for plants. They contain essential minerals, enzymes, and beneficial microorganisms that promote healthy growth. You can purchase worm castings from gardening stores or create your own worm bin to produce your own supply.
Additionally, seaweed is a fantastic natural fertiliser for bonsai. Seaweed contains an abundance of trace elements, minerals, and hormones that help improve root development, strengthen the immune system, and enhance overall plant health. You can use liquid seaweed extract as a foliar spray or dilute it with water and apply it to the soil.
Lastly, you can also make your own organic liquid fertiliser using kitchen scraps. To do this, collect vegetable peels, coffee grounds, and tea leaves, and place them in a container filled with water. Allow the mixture to sit for a few days to weeks, and then strain the liquid. This liquid can be applied to your bonsai as a nutrient-rich fertilizer.
Remember, when using organic fertilisers, it is important to follow the recommended application rates and not over-fertilise your bonsai. Organic fertilisers provide a slow-release source of nutrients, so it’s best to apply them sparingly and regularly to avoid nutrient deficiencies or imbalances. Happy fertilising!
DIY Natural Fertilisers for Bonsai

How to make compost tea
Compost tea is a nutrient-rich liquid that can be used as a natural fertilizer for bonsai trees. It is made by steeping compost in water, allowing the beneficial microorganisms and nutrients to be extracted. Here is a step-by-step guide on how to make compost tea for your bonsai:
1. Gather your materials
To make compost tea, you will need the following materials:
- Compost – Use mature compost that is rich in organic matter.
- A container – Choose a container that is large enough to hold your compost and water.
- Water – Use chlorine-free water, such as rainwater or tap water that has been left to sit for at least 24 hours to allow chlorine to evaporate.
- Aeration device – This can be an aquarium air pump with an air stone or a simple stirring device.
- A cloth or fine mesh – This will be used to strain the liquid when it is ready.
2. Prepare the compost
Fill your container with compost, leaving some space at the top. Break up any large clumps of compost to ensure good contact with the water.
3. Add water
Add water to the container, making sure to completely saturate the compost. The ratio of water to compost can vary, but a common guideline is to use 4 parts water to 1 part compost.
4. Aerate the mixture
If using an aquarium air pump, attach the air stone and place it in the container. Turn on the pump to create a flow of air bubbles, which will provide oxygen to the microorganisms. If you don’t have an air pump, you can simply stir the mixture vigorously for a few minutes.
5. Let it steep
Allow the mixture to steep for 24 to 48 hours. During this time, the microorganisms in the compost will multiply and release beneficial nutrients into the water.
6. Strain the liquid
After the steeping period, use a cloth or fine mesh to strain the liquid, removing any solid particles of compost. The remaining liquid is your compost tea.
7. Application
Apply the compost tea to your bonsai by watering the soil around the tree. You can also use it as a foliar spray by misting the leaves. Repeat the application every few weeks to provide ongoing nutrients to your bonsai.
Compost tea is a great way to enrich the soil and promote the overall health and growth of your bonsai. It is a natural and sustainable alternative to synthetic fertilizers, and the beneficial microorganisms it contains can help improve the soil structure. Give it a try and watch your bonsai thrive!
