What rate of Yates Sulphate of Potash should I use on my parsley

If I used Yates Sulphate of Potash what dilution rate is needed. Would it be similar to Thrive in a normal 9 litre water can ?

Dear Earle,

The dilution rate for Sulphate of Potash is to dissolve 20 grams of product into 9 litres of water and apply via a watering can over 2 square metres. This product is no longer ranged so consider using Yates Thrive Flower & Fruit Soluble Plant Food which has a high potassium level. Apply fortnightly.
