what is biochar
and why is it so good?

Biochar is charcoal that is used for gardening, horticultural and agricultural purposes.
It is carbon-rich and specifically designed for soil enhancement.
You can use it to nourish your soil, enhance growing conditions and get better soil structure.

●★●

Unlike other soil improvers, biochar does not decompose.
It will continue to do good in your soil almost indefinitely, making it healthy and fertile for decades to come.

●★●

And here’s a cool thing. Every time you dig in 1kg of biochar to your soil, not only do you see great results…
you can be proud that together we have helped a forest to take 3.6kg of CO2 out of the atmosphere
and buried it in your veg patch!

Quite simply, it’s great for the environment and perfect for the garden.

Biochar
helps your garden grow

01. manages nutrients

Holds on to nitrogen, phosphates and potassium. Vital nutrients do not get washed away with the rain. They are released directly to plant roots instead. 

●★●

02. increases beneficial bacteria

Helps soil to break down organic content quickly to feed your plants. Biochar is not broken down in soil.

●★●

03. quicker establishment & root growth

Trial results have shown higher plant survival rates and substantially increased roots systems. Works in all soil types and improves soil dynamics. 

●★●

04. manages soil moisture

In sandy soils, it absorbs many timesits weight in water, reducing the need for watering and creating less stress for your plants. And in heavy clay soils, it improves drainage. 

●★●

05. resilient, healthier plants

Creates healthy soils and vigorous growth, which yields plants proven to be resistant to drought and disease, including the devastating ash dieback disease

●★●

06. lasts for ages

Your biochar-enriched soil will last for thousands of years and will continue to work just as effectively, enriching the environment for future generations.

Four simple ways to use
biochar

in the garden
_

For 10% biochar in your flower beds or veg plot, give this a try. Sprinkle about 3kg raw biochar over 1m2 of soil. Then add a compost of your choice. Finally, dig it in to about 5 inches deep.

in rows
_

Make your biochar go further by adding it to planting rows or individual planting holes. Dig your planting trench, then sprinkle in a layer of biochar. Cover with your compost, place seeds/seedlings and backfill your trench. 

IN pots
_

Boost your pot plants by mixing raw biochar with your favourite compost. For a 10% biochar mix add 1kg to 40 litres of compost. Simply mix well, then get potting!

Dress the surface of the soil or plant pot witha 50/50 mix of biochar and compost. 1kg of raw biochar to 4 litres of compost should do the trick. Sprinkle pure biochar on the surface of a plant pot or soil around ornamental plants.
