Bonsai Specialty Soil Bags

Our bonsai soil, like a few of the other good bonsai soils, has, as its primary need, to maximize the air in the soil (of the right size air pore spaces), to be the best pH balance, well buffered, and otherwise neutral so as not to damage the plant.

Added to that we pick our soil particle ingredients to help the roots divide and develop branching, and to promote the beneficial fungi which live in conjunction with the roots and actually act as an extension of the root system.  Often, when the new soil matrix is seeded with these fungi, the newly developed (and cut back) root system (and thus the plant above)
hardly even slows down its growth.

Finally, our mix is perhaps the best sieved mix on the market to optimize
the soil particle size.

Soil Bags

Carefully sieved to the best Japanese sized soil particles, so as to maximize the aeration within the soil. All particles are the same size: red lava rock, "soilmaster" red highly baked clay, and our best slash pine (except for the pine bark particles which are slightly larger since they are a flatter shape.)

What Customers Are Saying…

The material you supplied, for the Shofu workshop and the Lakeland demonstration was the best I’ve had to work with on on this whole trip" =========================
"Your perlite bonsai mix is great –
It’s the best I’ve used!"  – (
I made the best soil I have ever made before.  I attribute this to your pine bark.  Thanks.  I’ve got the other guys mad at me.  I kept all that we bought for myself.  They’ll have to drive over for more 


We don’t measure by weight but by sieved, mixed volume. The sieve sizes on our commercial siever are measured in mms, and allow down to roughly 1/14″ material through. That said, we use that size of screen for all the inorganic materials. For the organic material we use a slightly larger screen size, since the coarse sieved pine bark that we use is flatter and more capable of compacting. The difference in screen size doesn’t diminish the amount of air in the mix in any significant way, however.

Actually, because the type of bark particles that we use are slightly larger, the degradation takes longer and as that degradation takes place (over a period of months and years), and takes place around the periphery of the organic particles, the amount of air in the mix actually slightly increases for the better part of the time used in the soil mix.

Mycorrhizae, other aerobic organisms and particles which benefit the aerobic aspect of the mix, further limit the degradation of the particle size, creating a matrix of hyphae which resist compaction and thereby increase the air in the mix as the particles degrade around their edges.

However, simply put, in answer to your original question, the ratio (by sieved but not mixed volume) in our mix is initially very close to 1/3 – 1/3 – 1/3; actually with slightly more air being donated to the mix by the pine bark.

This is the ratio we have developed and found to be most effective – and long lastingly successful – over the thirty-five or so years of refinement of our bonsai soil mix.

We hope this helps answer your questions without being too technical.
