This worm humus is a supercharged plant fertiliser. Using a 1:4 mix of castings to soil can increase root mass up to 150% and plant growth 20-30%.
Castings are nutrient and microbe rich, containing large amounts of Nitrogen, Potassium, Phosphates and microbes and enzymes.
Castings also have great water retention properties and assist in the delivery of water soluble nutrients to plants.
Additional benefits of the castings are their ability to protect plant roots from pathogens.
