Build Better Garden Soil
Help your soil hold moisture and nutrients while creating better conditions for roots. Wakefield biochar products give you practical options for in-ground gardens, raised beds, containers, and specialty plants.
Start with Premium Biochar for general soil improvement, or choose a blend with added biology, compost, or ingredients suited to specialty plants.
New to Biochar
Give Soil More Capacity
Biochar is a porous, carbon-rich soil amendment made by heating renewable woody biomass with limited oxygen. Mixed into soil, its pore structure helps create lasting space for water, nutrients, air, and soil life.
Biochar works alongside compost, fertilizer, and watering to help the root zone make better use of those inputs over time.
- Moisture: Biochar helps soil retain moisture between waterings, which can be especially useful in raised beds, containers, and fast-draining garden soil.
- Nutrients: Its porous surfaces help hold nutrients in the root zone instead of letting them move through the soil as quickly.
- Soil conditions: Biochar can support soil structure, air space, root development, and habitat for beneficial soil microbes.
Where Biochar Fits
Start With the Way You Grow
- In-ground gardens: Mix biochar into the soil around the planting zone.
- Raised beds: Blend biochar through the finished soil mix so water and nutrients stay closer to the roots.
- Containers: Use the product directions to build biochar into the potting mix without crowding out the drainage and air space each plant needs.
Biochar can also be mixed with compost or used in lawn projects. For large lawn areas, extensive gardens, or other high-volume projects, see Bulk Biochar to compare larger-format options.

Simple Garden Use
Mix, Water, and Keep Feeding the Soil
For Premium Biochar and Premium Biochar with CarbonBoost, aim for about 5–10% biochar by volume of the finished soil mix. Blend evenly and water thoroughly. Follow the mixing directions for Biochar Pro Garden Mix and the ready-to-use specialty blends.
When preparing a new planting area with Premium Biochar, mixing it with mature compost ahead of time is a helpful option. See the preparation FAQ below for timing and guidance around established plants.
Fall Soil Preparation
As you plan fall soil improvements, consider planting areas beside sidewalks and driveways that receive winter deicing-salt runoff. Research shows biochar can reduce salt stress in plants and soils. Follow the preparation guidance when incorporating biochar around established plants.

FAQ
Garden Biochar Questions
How much biochar should I use?
For Premium Biochar and Premium Biochar with CarbonBoost, aim for about 5–10% biochar by volume of the finished soil mix. Use the Biochar Calculator for a package estimate. Biochar Pro Garden Mix and the specialty blends have their own mixing directions.
How quickly does biochar work?
Biochar begins interacting with water, nutrients, and soil life after it is mixed and watered in. Visible plant or soil changes take time and vary with the soil, plant, weather, and garden care. Biochar is used for lasting soil improvement, season after season, rather than a quick fertilizer response.
How should I prepare biochar for my garden?
For new plantings, an optional preparation step is to mix Premium Biochar with mature compost and keep the mixture moist for about one to two weeks before incorporating it into your soil. This gives the biochar time to interact with nutrients and microbes before planting.
The best time to incorporate biochar is planting or repotting. Around established plants, gently blend it into accessible soil without damaging roots; surface spreading does not reliably move biochar into the root zone. For established containers, repotting is usually the most practical option. Consult a qualified arborist before working around dense tree roots.
Follow the product directions for blends with added biology or compost. See our guide to preparing biochar with compost.
Does biochar replace compost or fertilizer?
No. Biochar helps improve the soil environment and retain nutrients, but plants still need appropriate nutrition. Continue using compost or fertilizer based on your plants and soil.
Do I need to add biochar every year?
For Premium Biochar and Premium Biochar with CarbonBoost, an annual application is generally unnecessary if amended soil remains largely in place. Compost or other amendments may be sufficient. Consider replenishment when substantial amended soil is removed, replaced, eroded, or moved away from roots. Keep the total at about 5–10% by volume of the finished soil mix; this is not an extra dose each year. For Pro Garden Mix and specialty blends, follow their product-specific mixing directions.
