Root Booster is easy to use. Simply add the pelleted granules to potting compost or the soil at planting up time. Use one heaped scoop of Root Booster per 2.5 litres of compost. One application lasts all season.
The granules do change colour from brown to milky white as they absorb moisture from the air. This is the activated stage, it’s the colour it turns once in the soil or compost, but if it occurs in the pack, don’t worry, your Root Booster is still fine to use.
