Pro-Kleen Iron Sulphate is a long-lasting fertiliser, rich in iron, that helps prevent lawn disease, encourages growth of healthy dark green grass whilst suppressing worm casts. Iron sulphate is also known as ferrous sulphate and sulphate of iron. Benefits of using iron sulphate are: grass greening and turf hardening. Did you know that it also helps to keep your grass healthy throughout the winter months?

Why choose Pro-Kleen Iron Sulphate?

EXTREMELY POWERFUL, HIGH QUALITY 3-in-1 FORMULA

Our iron rich and long lasting formula encourages strong, healthy green grass to improve the appearance and quality of lawns. It's highly effective in grass greening and turf hardening!

USED & TRUSTED BY PROFESSIONALS

Pro-Kleen Iron Sulphate is used and trusted by greenkeepers, lawn keepers, park keepers and sports groundsmen for perfect pitches, green lawns and superior golfing greens all across the UK.

HELPS TO PREVENT LAWN DISEASE

Our thoroughly revised, tried and tested formula even helps to prevent lawn disease with its turf hardening qualities.

EASY, RESEALABLE TUB

Pro-Kleen's easy to use, resealable tub makes it easy to close after use and conveniently reseals for optimum freshness.

EASY TO USE

Simply refer to the suggested usage on the reverse of the tub, dissolve your chosen amount of solution into water and apply via watering can or sprayer onto your grass.

Grass Greening

For greener, healthier looking grass, mix with water at the rate of 10g-20g per 10 litres of water for 10 square metres of lawn. You can use iron sulphate at this concentration at any time of year as long as good soil moisture is available and there is no strong sun or heat!

2.5kg will cover over up to 2500 square metres 

1-2g per 1 litre of water per 1 square metre 

10-20g per 10L of water per 10 square metres.

Turf Hardening

Increase the concentration and not only will it have an amazing effect on the greenness of your grass but it will also start to ‘harden’ the turf making it more resistant to disease and fungal attack. This makes it a very common practice on sports turf in autumn and winter. For hardening, we recommend applying between September and April when plenty of moisture is available and when sunshine is unlikely.

2.5kg will cover over 1000 square metres

2-3g per 1 litre of water covers 1 square metre.

20-30g per litres of water covers 10 square metres

How to Kill Moss:
As a guide, use 5g to 1 litre of water when removing moss.

40-50g per 10L of water per 10 square metres. 

1kg Covers 100 square metres.

Mosses are plants, comparatively simple in structure and function and, with the Liverworts, comprise the Bryophyta family – one of the least complicated groups of the plant kingdom. Moss is unsightly and often hard to manage. Simply increase the concentration to get rid of it. Moss grows where there is nutrient poor soil, high acidity soil, compacted soil, or soil that drains poorly or where there is excessive shade basically where grass cannot survive. Sulphate of iron, commonly applied in winter or early spring removes the moss. After the moss turns brown, you can rake it loose with a garden to remove it from the lawn.
