When Kyodama no longer became available I started a search to find as near identical product as possible. My Pines had always thrived on 70% Kyodama so I wanted to repeat the success if possible.
After three years dismissing countless products I have actually found one which is better than Kyodama.
Phosphate and Nitrate free, it allows oxygen and nutrients to be stored for use when the tree requires it. Roots will actually grow through this product as with kyodama. Around half the weight of conventional grits it does not make the tree overly heavy.
Being (loosely) clay based it is completely lime free and studies thus far have been a big thumbs up. I’m just glad i found a product to take the place of Kyodama.
