killing lawn weeds and moss

Lawn Weeds are the Easiest Weeds to Eliminate!

The most effective way to deal with lawn weeds is to use a selective weed killer.

This is a clever weed killer. It knows that your grass has a single leaf (monocot) therefore it will kill everything that is not grass (dicot). So be careful you don’t venture off the lawn and catch an overhanging leaf from your border!

Simply mix the selective weed killer with water and spray your lawn or just the weeds if there are small patches dotted here and there.

If you have a lawn larger than 80sqm it might be worth buying a larger sprayer. It is easier to walk, spray and pump with the added benefit of not having to keep returning to the tap to refill. You can get one HERE

Verdone Selective Weed Killer is no longer available.  Weedol Lawn Weed Killer  IS available though and it’s even more effective!

  • It is always good practice to feed your lawn after spraying a selective weed killer. This will help strengthen the grass while the chemical is active Read our Guide on Lawn Fertiliser.
  • Two days after spraying, the weeds will actually start to grow. They will twist and look quite pale. Within a week or two the weeds will be brown and withered.
  • Mix some grass seed with ordinary potting compost and sprinkle over areas where the weeds are dying out. You can also use this method for bare patches in your lawn. The compost helps the seed to germinate.

Other Monocots include iris, bamboo, orchids and ornamental grasses. If you have a number of weeds amongst these monocots, you can use a selective weed killer successfully, without damaging the plants.

Monocot – strappy leafed plants

Dicot – everything on the planet except monocots!


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 maybe worth hiring a scarifying machine from you 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 porus 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 way. 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!


A New Alternative to Killing Moss

Mo Bacter

The Perfect Garden has been trialling 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 ’16 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.

We love lawns. If you have a problem with your lawn or need some advice then drop us a line in the comment box below. We would love to help. Even if it is just to tell us which spelling of fertilizer/fertiliser you prefer!
