Oh no! Another soil mix post!

[Clicio]

I've been trying a mix of Brazilian akadama (Qualitá), wich has acidic PH (5.7) and some cat litter (Diatomaceous Earth-DE), which is alkaline, averages 8ph,+ or -2 in my soil mix. So the result is neutral PH. For azaleas, I add pinus bark and less DE; for the others, crushed fired brick.
All sifted.
Another advantage of DE is insect control.
I'll keep you posted on the results.

We have Mayo-dama.
Comes from our central hills, used for making cement.

Clay that has become stone by being under the ocean.
Thus far the Tamarind loves it.
Good Day
