500g Sulphur Soil (North City NR3)

Apparently, this is for lowering soil PH if soil is too alkaline, for roses, rhododendrons, camellias, azaleas, etc. Don't know any more about it, as it was my neighbour's. Packet says "see box for application instructions", but we don't have the box. Maybe go onto 'Greenacres Direct' to check for garden application.
