Biochar is a stable, carbon-rich material made by heating organic biomass (like wood) in a low-oxygen environment — a process called pyrolysis.

It’s used to improve soil health, lock carbon into the ground, and reduce fertiliser needs by enhancing nutrient retention and soil structure.

At Bio-Bloom, we offer two types of biochar:

Charged Biochar – pre-loaded with natural nutrients and beneficial microorganisms. It’s ready to use straight away and gives immediate results for soil fertility and plant growth.

Raw Biochar – untreated biochar that acts like a sponge. Before use, it should be “charged” with nutrients (for example by soaking in compost tea, organic fertiliser, or manure) to avoid nitrogen drawdown in the soil.

Wood vinegar, also known as pyroligneous acid, is a natural liquid produced as a by-product when making biochar. It’s rich in organic acids, esters, and phenolic compounds, which make it excellent for:

• Stimulating plant growth
• Enhancing soil microbes
• Controlling pests and diseases naturally
• Reducing odours during composting
  

Bio-Bloom’s wood vinegar is carefully filtered and aged to ensure purity and consistency.

Both are produced through pyrolysis, where sustainably sourced wood is heated with limited oxygen.

• The solid portion becomes biochar (carbon-rich, porous material).
  
• The condensed vapours form wood vinegar, a nutrient-dense liquid.
  

This process locks carbon into the soil and captures valuable compounds, making it both regenerative and environmentally friendly.

• Improves soil fertility and structure
  
• Enhances water retention and aeration
  
• Reduces nutrient leaching and boosts fertiliser efficiency
  
• Promotes microbial activity and soil biodiversity
  
• Helps sequester carbon, combating climate change

• Acts as a natural biostimulant for plants
  
• Helps control pests and fungi when diluted properly
  
• Accelerates composting and reduces smell
  
• Balances soil pH and supports microbial life

Absolutely. Using biochar and wood vinegar together enhances the benefits of both:

• Wood vinegar helps “charge” biochar with soluble nutrients and organic acids.
  
• The combination improves nutrient retention, soil pH, and microbial activity.
  
• Ideal for regenerative agriculture, natural farming, and sustainable gardening.

If you buy raw biochar, it needs to be “charged” before applying to soil.

Here’s how:

1. Mix it with compost, liquid fertiliser, manure tea, wood vinegar or seaweed extract.
   
2. Let it soak for at least 7–14 days to absorb nutrients.
   
3. Apply 5–10% by volume to soil or compost mixtures.
   

Charging prevents the biochar from drawing nutrients away from your plants.

Bio-Bloom Charged Biochar is ready to use, no soaking or composting required.

• Simply mix it into soil or compost at 5–10% volume.
  
• For pots and raised beds: blend it evenly through your growing medium.
  
• For garden beds or lawns: spread and lightly incorporate it into the topsoil.
  
  It works instantly to improve nutrient availability and soil health.

• Foliar spray: Dilute 1:300 to 1:500 with water and apply to leaves in early morning or late afternoon.
  
• Soil drench: Use similar dilution rates and apply near the root zone.
  
• Composting: Add 10–20 ml per litre of water to accelerate breakdown and reduce odours.
  

Always test a small area first to ensure plants tolerate the mixture.

Charged biochar gives noticeable improvements within weeks, healthier plants, better soil texture, and stronger root growth.

Raw biochar results appear more gradually, as the soil ecosystem adapts.

Wood vinegar can improve plant vigour and pest resistance within a few applications.

Yes! Bio-Bloom ships biochar and wood vinegar anywhere in the UK.

Delivery times typically range from 2–5 business days.

Bulk and wholesale orders are available for farms, allotments, and garden centres.
