When to choose Biochar Pro Garden Mix™
Choose Pro Garden Mix when you want biochar plus compost in one bag for general garden and ornamental use. Blend it with existing soil when refreshing beds, filling a targeted planting area, or preparing containers and patio planters.
Choose Premium Biochar when you want to build your own mix with compost and other ingredients, or Biochar with CarbonBoost™ for added biological support. Choose Tomato & Vegetable Blend for edible garden beds, or Cactus & Succulents Blend for dry-loving containers.
How Biochar Pro Garden Mix™ supports soil
Biochar, organic compost, and mycorrhizae work together in a ready-to-blend soil conditioner. The blend helps support soil structure, water and nutrient retention, and beneficial soil biology.
Use it when preparing or replacing soil. Soil already amended with biochar may only need compost or other amendments rather than another biochar-containing mix.
How to use Biochar Pro Garden Mix™
Mix equal parts Pro Garden Mix and existing soil by volume, so the product makes up about 50% of the finished soil mix. Mix thoroughly with garden soil, raised-bed soil, or potting soil.
No additional charging is needed. Mix with soil as directed, then plant and water in. Continue feeding as appropriate for your plants and soil conditions.
For larger beds or uncertain quantities, use the Biochar Calculator or contact Wakefield for product help.

Pro Garden Mix™ questions
Can I use Pro Garden Mix as a standalone potting soil?
Pro Garden Mix is designed to be mixed with other growing media. Mix equal parts Pro Garden Mix and existing garden soil, raised-bed soil, or potting soil by volume. For example, combine one scoop of Pro Garden Mix with one scoop of soil, so Pro Garden Mix makes up half of the finished mix.
Do I need to charge Pro Garden Mix before use?
No additional charging step is needed. Pro Garden Mix already combines biochar with organic compost and mycorrhizae. Simply mix it with soil at the recommended 50/50 ratio by volume and water it in.
Do I still need fertilizer when using Pro Garden Mix?
The compost contributes nutrients, and biochar helps retain nutrients for plant use. Additional fertilizer may still be needed, depending on your plants and soil conditions. Continue feeding as appropriate for what you’re growing.
