Moss is a major headache for lawn lovers. Unfortunately, in reality, most lawns will be rarely free of moss, this is due to our ever-changing climate and the conditions our lawns grow in.

Take each season as it comes.  Large amounts of moss can easily be treated with fertilizers containing iron (ferrous sulphate). Some examples are Lawn Sand and Lawn Builder with Moss Control. Repeated practice of using fertilisers containing iron, moss removal and aeration will help keep moss from getting a hold on your lawn.

It is always best to treat moss early in the spring, which is why we prefer to use lawn sand, this has a small nitrogen content but a very high iron content. The iron will hammer the moss and the nitrogen will give the grass a “pick me up” tonic.

Apply the fertiliser when the lawn is damp and rain is NOT imminent the iron needs to sit on the moss for at least 24 hours (36 hours is best) to work its magic. After this period, rain or a watering would be perfect to wash the nitrogen into the soil. After 3-5 days the moss will start to turn black. Leave for a week or two and then remove with a plastic rake. We prefer these PLASTIC RAKES as they are lighter to use. The plastic tines don’t dig into the turf like a metal rake would, making the job a lot less hard work. If the moss is very thick it may be worth hiring a scarifying machine from your local hire shop for around £40 for half a day or even investing in your own. There are plenty to suit your budget from electric to petrol machines. There are some examples HERE with customer reviews to help you decide which machine suits you best.

  • Moss loves damp compacted areas of soil (You will notice moss growing on porous roof tiles and brick wall tops). The more you can keep the surface of your lawn open by raking or aeration the less chance moss will have to grow.
  • Creating good drainage. Hollow tining or spiking your lawn will allow the surface water to drain away. AERATION SHOES may look ridiculous but they are brilliant and really do help to break up the surface and get fresh air into your lawn!

An Alternative to Killing and Removing Moss

No Rake Moss Removers are fast becoming the moss killer and fertiliser of choice. Ideal for gardeners who struggle to remove the dead moss by means of raking or scarifying.

These fertilisers use large doses of Potassium to kill the moss, the moss then breaks down and is consumed by an already present bacteria, Bacillus.

Although this can be a slower process of removing the moss and fertilising the lawn, usually around 3-4 weeks, the potassium element builds strong disease resistant grass compared to the fast, grass growing nitrogen based fertilisers we have been used to in the past.

Evergreen No Rake Moss Remover has not been on the market long and 2018 spring has been particularly late so the jury is still out. Mo Bacter has been on the market longer and has some impressive 5 star reviews.

Mo Bacter

The Perfect Garden has been using Mo Bacter, a new product which breaks moss down naturally. On purchase we were quite sceptical however, we are experiencing some very interesting results!

This fertiliser/moss killer really does eat the moss, breaking it down to produce an organic fertiliser directly to your lawn.

In fact, it does such a good job you hardly need to rake the moss out at all.

It’s now May ’18 and the areas of grass that we treated with Mo Bacter are considerably greener with more prolific growth than surrounding areas.

Mo Bacter is quite expensive compared to other moss killers but if you are not a fan of raking the moss out, then this could be for you.
