Transform Your Garden with Biochar
Healthier Plants. Happier Soil. Holistically Good Gardening.
What is Biochar?
Biochar is a powerful, all-natural soil enhancer made by heating organic materials (like garden trimmings and crop waste) without oxygen- a process called pyrolysis. The result? A long-lasting, charcoal-like material packed with tiny pores that hold nutrients & water, improve soil structure, and support plant growth.
For your gardening:
– Perfect for pots, beds & borders
– Boosts water retention & plant health
– 100% natural, locally made from organic waste
Why Gardeners Love Biochar?
Enriches Soils and Builds Microbe Megacities
Biochar dynamically creates a thriving habitat for the microbial life that breaks down organic matter and feeds your plants. It also improves soil texture, prevents compaction, and increases aeration– particularly important in dense, heavy soils that get waterlogged easily.
In trials, biochar-amended soils showed:
- 20-40% improved soil porosity
- Better root growth and nutrient uptake
- Higher levels of beneficial bacteria and fungi
Improves Nutrient &
Water Retention
Biochar’s honeycomb structure acts like a sponge, soaking up nutrients and water before slowly releasing it back when plants need them. Especially helpful in:
- Sandy soils
- Pots and containers
- Hot or drought-prone gardens
Root Development
Biochar helps roots dig deeper and draw in nutrients more efficiently. Gardeners report healthier flowers, bigger yields, and better resistance to disease across plant types and contexts.
It’s especially useful for:
- Improving root veg performance
- Helping young plants establish faster
- Boosting blooms in containers or borders
Safe, Organic & Long-Lasting
Biochar is:
- Non-toxic and free of synthetic chemicals
- Certified safe for gardens, with pollutant levels lower than average garden soil
- Extremely stable. A single application can last for decades or longer, unlike composts or mulches
How to Use Biochar in the Garden
Raw biochar can temporarily soak up nutrients from the soil, so it’s best to “charge” it first.
How?
Mix 50/50 with compost, leaf mulch, worm castings or manure and leave for 1–2 weeks. Or simply soak it in compost tea.
- Containers: Use 5–10% of the total potting mix
- Borders: Mix 1–2 handfuls per square metre into the topsoil
- New plants: Add to planting holes before transplanting
Good for Your Garden & the Planet
Unlike compost or mulch, biochar does not break down quickly. It stays in the soil for decades- locking away carbon and fighting climate change.
Just 1kg of biochar removes up to 3kg of CO₂ from the atmosphere, storing it in the soil for generations. That’s climate mitigation, right there in the garden.
Local Impact, Global Change
Silver Bullet Biochar works in partnership with local farmers in Sri Lanka. We turn agricultural waste into powerful, soil boosting biochar, creating a circular economy and knowledge transfer network that:
- Supports and empowers smallholder farmers
- Reduces pollution and waste from open burning
- Educates communities about soil health
- Robustly removes carbon durably & sustainably
