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.

Been using it for 2 years, tomato yields gone berserk, put my family and friends onto this with similar results.
So far I think I am happy with this product ! I possibly will know better once veggie season comes
A lot of brands on the market. This one is at a competitive price. I believe they all do the same job. It's the same chemical after all.
It looks like a good product. Haven't used it yet.
It's a must for any plants or vegetables and especially for shallow roots vegetables such as garlic.
