Akadama Bonsai Mix 14 L · 1 mm
Akadama is one of the most recognised Japanese substrates for bonsai. The fine 1 mm grade distributes closely around the roots, while its porous grains combine drainage and aeration with useful moisture retention. The 14 L pack is suited to larger containers or several repotting jobs.

Composition & profile
Japanese granular clay in a 1 mm grade
Akadama is a natural, inert mineral material of Japanese origin. Its granular, porous form leaves air spaces and moves excess water away while keeping useful moisture available inside the pot.
- Porous grains: Hold controlled moisture without closing the air spaces needed around the roots.
- Fine grade: The nominal 1 mm particle size distributes evenly when worked gently without heavy pressure.
- Visible colour change: The grains darken when wet and become lighter as they dry, providing a practical cue alongside checking the pot.
- Inert base: Contains no added fertiliser, allowing feeding to be managed separately for the individual bonsai.
Air and water balance
Porous grains retain moisture while the granular arrangement maintains drainage and open air spaces.
Clearer watering control
The change from darker wet Akadama to lighter dry material acts as a visual cue alongside checking the pot itself.
Adjustable mix
Use it alone or combine it with other mineral materials, tailoring the composition to the species, container and climate.
Use & repotting
Use alone or as the base of a fine 1 mm bonsai mix
Suitable for many bonsai species, with the final ratio adjusted to the plant, pot, local climate and watering routine.
- Deciduous bonsai
- Evergreen bonsai
- Indoor bonsai
- Mixes with Kiryu
- Mixes with Kanuma
- 1 mm grade
Sieve or rinse lightly only if visible dust is present, so very fine particles are not transferred into the pot.
Use Akadama alone or add Kiryu, Kanuma, lava or pumice to match the needs of the individual bonsai.
Work the fine 1 mm grade gently between the roots and secure the tree without crushing the grains.
After repotting, water evenly until clean water exits the drainage holes, then allow all excess to drain away.
Match the grade and watering routine to the individual bonsai
The fine 1 mm grade needs careful distribution without heavy compression. Check colour, actual moisture and drainage speed rather than following a fixed watering calendar.

Frequently asked questions
Quick answers about grade, blending, watering, feeding and repotting.
01What exactly is Akadama?
It is a natural, inert Japanese mineral material in granular form. Its porous grains combine moisture retention with drainage and aeration around the roots.
02What does the 1 mm label mean?
It is the nominal grade of this product. Work it without heavy compression and remove only visible fine dust before use.
03Can I use it on its own?
Yes. It can be used alone or as the base of a mix with Kiryu, Kanuma, lava, pumice or another suitable material. The ratio depends on the species, pot and climate.
04How do I know when to water?
Akadama darkens when wet and becomes lighter as it dries. Use this change as a cue, but always check moisture inside the pot before watering.
05Does it contain fertiliser?
No. Akadama is an inert substrate with no added fertiliser. Apply feed suited to the individual bonsai and follow the directions on the fertiliser product.
06When should it be replaced or repotted?
Over time the grains may begin to break down and drainage may slow. Check the structure, drainage rate and roots; the right interval varies with species, climate and cultivation.
