Improve the structure of your soil with the Soil & Microbe Booster by Plant Runner. This secret weapon activates your plant’s natural defences against pathogens, like the ones that cause root rot. It increases the availability of nitrogen to your plants.

Some things just belong together. Like this mix of biochar and frass. Frass is an all-natural fertiliser made from insect manure and bursting with nutrients and good microbes. Biochar is a charcoal-like substance that comes from heating raw materials without oxygen. 

  • Biochar keeps plants kicking through dry spells and overwatering. It boosts the capacity of soil to hold nutrients and water, complementing the richness of frass.
  • Frass on its own boasts a nitrogen-phosphorus-potassium (NPK) ratio of 4:2:2. But it’s still full of those underrated trace nutrients to help your plants flourish: iron, copper, zinc and so much more.
