Every great garden needs phosphorus – it’s the nutrient that fuels strong roots, healthy growth, vibrant flowers, and bountiful harvests. BioPhos® delivers a big dose of phosphorus in a natural, gentle way that your plants and soil will love.

Made from high-quality rock phosphate that’s been biologically activated with beneficial fungi and enriched with fish nutrients, BioPhos® gives your garden phosphorus in a form that is more readily available to plants, while still releasing slowly over time. This means your plants get the boost they need for root growth and flowering, without the waste or runoff that can happen with harsh, highly soluble fertilisers.

Alongside phosphorus, BioPhos® also provides valuable calcium, which helps balance soil pH and strengthen plant cell walls, and trace organic nutrients to support healthy soil life. The result is stronger plants above ground, a healthier root zone below ground, and living soil that stays fertile for the long term.

Perfect for veggie patches, flower beds, fruit trees, and general garden use, BioPhos® is the natural way to give your garden the phosphorus boost it needs to thrive.
