Base Substrate Mix


This is the soil mix we use in the nursery to ensure our Bonsai grow vigorously and stay healthy. It is a standard mix used to ensure drainage, aeration and just enough moisture retention. 

Depending on the Bonsai or Pre-Bonsai being potted we add substrates like Akadama, Pumice, Lava Rock, Vermiculite, Perlite, Kanuma and others. But this is the basis for most of the substrate mixtures we use and recommend. 


Base Substrate Mix:

  • 60% Sphagnum Peat Moss
  • 20% Perlite
  • 10% Crushed Dolomite for acidity balance
  • 5% Rooting Agent 
  • 5% Mycorrhiza

Great Product

This is a great mix for my bonsai’s, something I wish
I had found a long time ago. It’s perfect blended with
other products to complement the substrate mix.

I ordered extra to have on hand for future repotting.

Thriving Hawaiian Umbrella Bonsai

The plant came securely packaged, healthy, and ready to plant with the base substrate mix and it’s now thriving.

Good dirt!

Good high quality earth for bonzai growing.
It's not very dense. Perfect for roots to spread.
