Richgro Sulphate of Potash is a fertiliser rich in potassium that encourages growth of quality fruit and colourful flowers. It also helps plants resist fungus attack.
It is an effective means of increasing potassium levels when using organic fertilisers that tend to be low in potassium.
The granular formula is easy to spread and provides a slow release of potassium. It is ideal for use on pot plants, gardens and lawns that require a boost.
