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 soluble formula is easy to dissolve and provides a slow release of potassium. It is ideal for use as a foliar spray on pot plants, gardens and lawns that require a boost of potassium.

I love this product as its soluble and increase blooms
I bought this product last week again because it helps my vegetables make more fruit i been using it for few years now .
Organic nutrient for the soil, to encourage flowering in your plants
I add this to Thrive Flower and Fruit to improve flowering with some plants such as Gerberas, petunias. pansies etc.
this is a good product and is a reasonable price it helped take away the yellow in the leaves of my favourite cherry tree which my grandfather planted. but I couldn't help but notice that whoever made this product online misspelt and used the wrong word it should be sulfate not Sulphate
