What Are The Best Moss Killers For Lawns & Grass Areas?

A majority of grass lawns have issues with invasive moss. Once this happens, it spreads at a high rate.

If you are looking for a solution to stop it from killing and suffocating your grass, then I have listed the best moss killers for lawns to help rid your grass of moss.

There is nothing worse than caring for your grass, feeding it and watering daily only to discover that there are patches of moss appearing between the blades of grass.

This can devastate a lawn if not correctly treated in time, moss will grow at an unusual rate especially in boggy, damp or shaded areas.

Unlike artificial grass, a natural lawn takes a lot of work, but as you continue to feed and water your garden, you are creating the right environment for moss to thrive.

Why Is Moss Growing On My Grass?

Treating your lawn with the best moss killer is only the first part of any moss removal treatment.

When you discover that you have patches of moss, then you need to sort the route of the problem.

Here are a few examples of the perfect moss growing environment:

1. No drainage: means your soil is always damp/wet
2. Overwatering: Adding too much water and not allowing it to dry or drain away
3. No sunlight: shaded areas will cause moss to grow under trees or behind buildings
4. Winter months: because the sun does not rise above fences or trees
5. Compacted soil: You will need to aerate your soil
6. Low PH level: your soil needs lime

All the points above have simple treatment plans to bring your lawn back to life. We would suggest you first get your soil PH tested and start from there.

For a more immediate solution, we have listed the best moss killers we have been using for customers who require severe moss removal from their grass lawns.

These moss killers should be applied to your grass every week, depending on the severity of your moss issue.

Best Moss Killers For Grass Lawns

The main ingredient of killing moss is iron sulphate; all the professional gardeners and greenkeepers use this form of sulphate.

All the best moss killers also use iron sulphate to improve the effectiveness of their grass treatments.

But, if you do not want to use chemicals such as iron sulphate, then there are a few options listed further down this article for you to implement.

So, without further ado here are the best moss killer brands that work every time recommended by our experts.

1. Pro Kleen Iron Sulphate
2. Maxicrop Moss Killer
3. Guard-EN-Force

1) Pro Kleen Iron Sulphate (Best Option)

For a 2.5kg tub of Pro Kleen Iron Sulphate, you pay around £13 which treats 2500m2 area. We have used the Pro Kleen brand since 2006 and have always had great results.

It is the market leader because it contains a fine powder that should be dusted over the lawn and not diluted. If you dilute this stuff, it will soak through to the roots of the grass and dissipate.

When you sprinkle the powder, leave it for a day and then water your lawn. By this time the powdered iron sulphate would have been absorbed into the topsoil. After a few weeks of use, you will notice the moss going brown and dying off. After a month, check PH levels and air your soil if possible.

Best Option for Managing And Killing Off Moss

From experimenting over the years, we can safely say that use both Pro Kleen Iron Sulphate & Maxicrop Moss Killer alternatively will remove any moss plus rejuvenate your lawn.

But, you have to get to the root of the moss issue. If you are struggling to keep on top of the moss, then we would advise you to seek some professional help with the soil.

Grass lawns grow best when their roots are drained and have the right nutrients, moss is invasive and will strangle the roots until the grass has been replaced by moss.

Here are a few videos to help you diagnose and kill any moss:

Conclusion

If you have a serious issue with moss killing your grass then the options above will work well.

Catching the moss growth early on will likely increase your chances of your grass recovering without any grass seeds being sown.

Remember that moss will kill grass off by strangling its roots and depriving it of nutrients.

If your grass area is large and you have a severe case of moss, then we would advise you to seek professional help with larger areas.
