Potassium K (Potash) has a NPK ratio 0:0:49 and is essential for flower and fruit production. Containing the essential nutrient potassium, Sulphate of Potash provides plants with greater resistance to weather and disease, as well as promoting the development and colour of flowers and increased fruit yields.
Why use Sulphate of Potash?
Plants low in potassium are stunted in growth and provide lower yields. Excessive levels of potassium can lead to magnesium and calcium deficiencies. Minerals and trace elements are an important requirement for good plant health. Over time, with each and every harvest, the soil is depleted of these vital ingredients, and they also need replacing.
How to apply Sulphate of Potash
Sulphate of Potash can be raked into the soil, used as top dressing or used as liquid feed.
Prior to planting or sowing vegetables Sulphate of Potash can be used as a top dressing for established plants, sprinkled evenly between the rows once or twice during the growing season. For fruit trees and bushes a top dressing can be applied in early spring.
When to apply Sulphate of Potash
Use twice during growing period.
Which crops/areas will it benefit?
Potatoes, fruit and tomatoes all need high levels of Potassium to crop well. It is beneficial for vegetables and fruits (particularly tomatoes, cane fruits and blueberries), fruit trees and soft fruits. Also ideal for flowering plants and shrubs where it promotes bigger, vibrant blooms.
