Moss is a common problem in gardens for a variety of reasons. It can give the lawn an uneven colour and feel spongy to walk on.
Moss often occurs when there is sparse grass cover, on compacted or waterlogged soil, in shady areas, or on soil that is lacking in nutrients or too acidic.
Moss killers are an easy and effective way to rid your lawn of that ugly moss. The moss will die quickly after treatment and can then be raked or scarified out.
So, if you want to start using moss killer, read these helpful tips to help you make an informed purchase:
The Benefits of Using Moss Killer
If allowed to get out of control, moss can overrun your lawn. It often outcompetes grass and will steal valuable water and nutrients away. As a result, moss will spread, killing off your grass.
A lot of moss on the lawn will look patchy and spongy, it won’t give you the smooth, well-groomed lawn that you’re after.
Using a moss killer will stop this spread, and the majority of them will actually fertilise your lawn and help improve its appearance.
Moss requires a moist environment to thrive; unlike most other plants, it doesn’t have roots to transport water and nutrients. The best way to treat moss is to dry it out completely, and this is how a moss killer works. Most moss killers contain iron, which can dry out the plant over time.
The best moss killer products will also improve the health of your lawn. If you have a lot of moss you may need to repeat the application. Most moss killers contain iron sulphate which kills the moss as well as greening up the lawn. At lower concentrations, these products can be used as a lawn tonic.
What’s Best – Liquid or Granular Form?
Both liquid and granular form moss killers are very effective.
One factor that may affect whether you choose one or the other is the type of spreader you have available.
If you already have a granule fertiliser spreader, you may be more comfortable with granular moss killer. Equally, if you normally use a liquid sprayer when fertilising, or have a watering can with a fine-holed rose, it might suit you better to use liquid moss killer.
Pros of Liquid Moss Killer
- If applied properly, gives very even coverage
- Easily and quickly absorbed
- Easy to apply
Cons of Liquid Moss Killer
- May not last as long in storage as granules
- Shouldn’t be used before rainy weather
Pros of Granular Moss Killer
- Can be ‘slow release’ – lasts longer and may be more effective
- May be cheaper than liquid products
Cons of Granular Moss Killer
- May burn the grass if not carefully and evenly applied
- Can be more difficult to apply evenly
Moss Killer With or Without Lawn Feed?
All of the moss killers featured in these reviews also advertise themselves as lawn feed. Personally, I think it’s best to buy a moss killer combined with lawn feed because when moss dies off it can leave sparse patches. If the lawn is treated at the same time, it won’t take long for the grass to grow and fill in these areas.
However, if your lawn has been really overrun by moss, you might want to consider buying a specified moss killer. This will be the best way to really tackle a carpet of thick moss.
