How to use
Mix Pre-Mix into your soil at the rate on the label, before you plant. It is Biobizz's own way of enriching a soil, and its microbes help give vigorous growth, plenty of flowers and good natural resistance to disease. It is the same Pre-Mix that goes into Biobizz All Mix.
It suits a lightly fertilised soil such as Light Mix. Once plants are growing, feed them by the Biobizz feed chart. More soil improvers are in soil amendments.
