What To Look For in a Moss Killer
Moss killers come either as concentrated liquid, soluble powder or solid granules. Choose liquid moss killer or soluble powder if you want something easy to apply. It can be applied using a watering can with a rose attachment, meaning you can use equipment you already have. Alternatively, you could use a garden sprayer over a large area.
I recommend liquid-form moss killer if you’re worried about grass burn. Because the solution is diluted, there’s less danger of patchy application. Patchy application can lead to areas of product concentration (which ultimately burns grass!).
However, if you already have a spreader for granulated fertiliser, applying a granular moss killer will be straightforward. Plus, granulated moss killer is a good choice for those on a budget – it’s typically cheaper than liquid products.
Diluted moss killers often show visible results within one to two days. Although, they shouldn’t be applied if rain is forecast as they may wash away and become less effective. Granular moss killers generally take effect in around two weeks. They slowly release their active ingredient so bad weather shouldn’t reduce their effectiveness.
One final tip: a combination moss killer and lawn feed is also worth looking out for, as this can help prevent bare patches after the moss has died off.
I recommend the Tradefarmni Iron Sulphate Premium Moss Killer as the best moss killer overall. This fast-acting moss killer offers the best of both worlds: it’s a powder that can be applied dry or dissolved in water. It comes in a 5 kg resealable tub with enough product to cover around 1000m² – great value for money as well!
