How to use Harris Charcoal

Using Harris Charcoal is straightforward. For most potting situations, mix 1 part biochar with 9 parts potting soil before planting. This gentle incorporation keeps the soil texture familiar while adding the benefits of the biochar.

• Indoor and terrarium applications: blend into substrate or apply as a light top-dress near the root zone.
• Outdoor and ornamental use: incorporate into topsoil before planting or during soil refreshes for long‑term resilience.
