How to Use Espoma Organic Bonsai Mix

Repotting Bonsai:
Carefully remove the bonsai from its container, loosen the outer root mass, and trim roots as needed. Add a layer of Bonsai Mix to the bottom of the container, position the tree, and fill around the roots with fresh mix.

Drainage Support:
Use a container with proper drainage holes and add mesh over the opening to help keep the mix in place.

After Repotting:
Water thoroughly and place the bonsai in a protected area away from direct sun and wind while it recovers.

Top Dressing:
Apply a thin layer to the surface of the container for a clean, decorative finish.

Check moisture regularly and water as needed based on your bonsai variety, container size, and growing environment.
