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!

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

About Moss:

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.

Causes of moss invasion:

  • A moist turf – poor drainage encourages the fern-like and tufted mosses
  • A very dry soil, e.g. over drains, on mounds and ridges
  • Cutting grass too low 
  • Diseased turf
  • Dry acid soil
  • Low fertility / deficiencies of plant nutrients
  • Low nutrient status
  • Over-consolidation of the soil
  • Shade from hedges, trees, buildings and topography – north facing lawn
  • Prolonged periods of wet weather
  • Time of year – autumn, winter and spring

Well it certainly killed the moss almost immediately. Now I've got 2.49kg left......... a smaller size might be useful for some of us town dwellers! But it did the job, just fine.

Yes, this can be used in Autumn, Winter and Spring. The concentration would depend on what you are using the Iron Sulphate for. Please see product details for application on grass greening, turf hardening or removing moss.
Does it get rid of wormcast

We are not aware of this product detering moles, but it will surpress worm casts.
Can this product be used on artificial grass to kill the weeds at the edges?
This product will not kill weeds, and we would not advise you to use on artificial grass.
How long after applying Iron Sulphate before reseeding bare patches?
Once the moss has blackened and been raked away from the lawn, we would advise you to leave one to two weeks before reseeding.

Although the product is not classified as environmentally hazardous, this does not exclude the possibility that large or frequent spills can have a harmful or damaging effect, so we would advise to avoid contact with the pond.
