Verigrow is manufactured by Veratin, an Australian public company. It is an innovative all-purpose fertiliser and soil improver made using 100% Australian low grade wool. Wool is a sustainable and rich source of amino acids (more than 75% of wool is made of amino acids). Verigrow contains an organic (from amino acids) and an inorganic source of nitrogen (12% w/v total N). The inorganic nitrogen provides an immediate source of nitrogen while the organic nitrogen provides a slow release and longer lasting effect. You can use Verigrow on anything and everything including lawn, fruit trees, vegetables, flowers, natives, herbs and more.
