Charlie Charcoal™ is a high quality horticultural charcoal/biochar that is of great benefit in sandy soils. As a permanent source of carbon, charcoal acts as a sponge to hold onto water and nutrients (having a high cation exchange capacity or CEC) and has a very large surface area - making it an ideal home for millions of beneficial soil microbes.
Charlie Charcoal™ is quite unique among biochars as it has a very low pH, so will be hugely beneficial to people in coastal regions that struggle in limestone/sandy soil; and it also means that Charlie Charcoal™ is a great addition to pots and planters where you are wanting to grow acid loving plants (eg. azaleas, camellias, blueberries, gardenias).
Key benefits of using Charlie Charcoal™ in your soil are:
Lowers pH of alkaline soils which improves mineral uptake by plants
Increases nutrient holding capacity in the root zone.
Supports soil microbial activity which help feed your plants.
Provides high level of silicon which improves plant disease resistance
Provides high levels of iron which combats iron deficiency and leaf chlorosis.
Low phosphorus levels make it safe for use on native plants.
An excellent addition to compost bins and can reduce smells.
Improves wettability and water holding capacity in sandy soils
Increases soil organic matter and carbon levels on a permanent basis.

Charlie Charcoal™ is non-toxic and safe to use for all plants. It is Certified Organic. The use of a dust mask is recommended when this product is dry as fine dust particles may become airborne.
Charlie Charcoal™ should not be applied where a source of ignition could ignite a high concentration of airborne particles.
TOP TIP: We can also supply beneficial microbes to inoculate Charlie Charcoal™ before using it in your soil. Super charge it by adding liquid nutrients like kelp, fish hydrolysate or worm juice - mix the nutrient liquid with a bucket of water, tip 5 litres of the liquid into a bucket of Charlie Charcoal™ and leave for a few hours before applying. (Think of charcoal as a sponge with billions of tiny holes to fill, so nutrient charging your Charlie Charcoal™ will give you great results in your garden much sooner.)
