Worm Castings - Vermigro

R55 - R110


Wurmbosch Vermigro worm castings 100% organic plant food. This organic fertilizer is produced from green garden waste material that earthworms, through their unique digestive system, have converted into castings which are rich in micro-organisms and packed with minerals that are essential for plant growth. These minerals include concentrated nitrates, phosphorus, magnesium, potassium, and calcium. 

Vermigro is the only vermicast product in the country certified by the Department of Agriculture, Forestry and Fisheries. These worm castings have undergone a fine sifting (2mm) to ensure their purity.
