How it works

What happens underground

  1. Add it at planting

    A teaspoon in the hole, or stirred into your watering can.

  2. Fungi join the roots

    Endo fungi for veggies and flowers, ecto fungi for trees. Both grow out into the soil.

  3. Roots reach further

    Your plant can draw water and nutrients from more soil.

“This product was recommended by my local organic nursery. I now use it on every new tree and bush I plant. A little goes a long way so you get a lot out of one can.”
