Symptoms include poor flowering and fruit sets, as well as the leaves turning yellow.

How & When to use our Sulphate of Potash as a Fertiliser

As with all feeds, pants can only intake the potash when they are actively growing. This means feeding them between Spring and late Summer. They often require more potash just after flowering or bearing their fruits. This is so they can keep healthy roots after all the nutrients have been used up.

Use every 6 weeks (4- 5 times) during the growing season. Don’t use if you’ve recently fed with another high potassium fertiliser.

Which plants to use Sulphate of Potash

You should use sulphate of potash on any plants which flower or fruit and vegetable plants from which you want a bigger and better yield.

Potash is necessary for acid loving plants such as Rhododendrons, azaleas and camellias. Blueberries also have a preference for a acidic soil so feeding them with potash is best too.
