This Liquid Bonsai fertilizer is a great way to control fertilization when watering. With a liquid fertilizer, you are able to regulate feedings. 

Mix one teaspoon in 1 litre of water when feeding between May to November. For indoor Bonsai, you can use half a teaspoon in 1 litre of water for plants that are growing well and could use little nutrients. 

This bottle is enough for 90 litres of full strength fertilizer of 180 litres of half strength. 

Never feed or fertilize a Bonsai that is not doing well, either showing signs of stress, leaf loss, browning or any other issues. 

Soil (Substrate)

Bonsai soils are usually a mixture of organic potting compost (Pine Bark or Forest Floor), Akadamapumice, lava rock in varying amounts. 

It is important for the soil have good water retention while also draining well, along with very good aeration. The quality of the soil directly affects the health, size and growth of your tree. One of the worst things you can do to your tree is plant it in regular garden soil. Garden soil hardens when it drys and can often lead to a disadvantage when growing a Bonsai. 

Soil mixtures can be purchased here, but given their weight and cost of shipping, you can also easily make your own. 


Depending on the type of Bonsai you're growing, here are the general formulas for successful mixtures. 

Deciduous Tree (Leafy and looses leafs in the fall)

50% Akadama

20% Pumice

20% Lava Rock

10% Potting Compost


Coniferous Tree (Evergreen like Juniper, Cedar)

1/3 Akadama

1/3 Pumice

1/3 Lava Rock


If you are not able to check on your Bonsai's moisture levels daily, add more Akadama to the mix. 

Given how these soils erode over time, repotting every 2-3 years is required. 


Here are some suitable replacements if you cannot find the recommended types of soil.

  • Akadama - fine fired or baked clays, some even recommend cat litter as a substitute. 
  • Pumice - fine crushed aggregates, expanded shale and vermiculite.
  • Lava Rock - This can be replaced with fine gravel or you can also look into purchasing a larger lava rock at a hardware or gardening centre and crushing it. 



One of the best and easiest ways to fertilize your Bonsai, is to add a liquid fertilizer mix when water your Bonsai's once a month during the spring/summer. If your Bonsai looses leaves in the winter there is no need to fertilize it then. If you have a coniferous tree, fertilizing the tree once in the beginning of winter and once in the middle of winter should be sufficient.

So nice to get Bonsai specific Food!

I love the folks at and trust that the products they sell and support will do their job. I was very pleased to find Bonsai food with clear instructions for use. I have only used it once but look forward to starting a feeding routine in May as instructed. This food can be used for African Violets and Succulents as well which is great!

Stephan G. (Canmore, CA)
Very convenient and works great!

I have been using this product for a few weeks now. One bottle of 250 ml concentrate makes 50 L of feed. It is very convenient to use as compared to solid pellets. It works well and new buds started appearing after a couple of applications.
