Soil sizes are a good thing ? or are they

(Bill Daniels) #1

There are my three basic soils

Akadama You buy the size its either small - medium - or large

pumice You need to sift. into different grades

red lava You need to sift. into different grades

Now my questions:

  1. Is there a need to micro - manage the soil culture in bonsai soils ? Such as 4.5 mm screen verses 3 mm screen? Then rebooting a medium size bonsai 12 - 16 inches high.

  2. Would it be better for the pumice & lava to be slightly larger than the akadama for needed air space in the root zone? such as using medium size pumice & lave with small akadama?

I try to keep all particles the same size when blending different ingredients. And I definitely don’t get too picky about exact sizes. I use small mix for small and most medium trees, and larger mixes for larger trees.
