How to Choose the Best Moss Killer for Lawns?

As you can see, there is a large selection of moss killers available. But how can you choose the right one for your lawn? To help, we have created a simple buying guide below:

Basic Tips for Using Moss Killer Effectively

There is no denying that using even the best moss killer can be tricky. It requires forethought and careful application. If you are not careful, you could damage your lawn.

The first tip is to check the best time to use the moss killer. Some moss killers are seasonal and should only be used between certain months. Others are safe to use all year.

Next, you must always read the instructions and be liberal with your application. Moss killers are safe to use and will not kill grass, but if you saturate your lawn, you could end up burning your grass.

Finally, always check if you need to treat your grass afterwards. Most moss killers kill moss but do not remove it. You may need to rake the grass afterwards to remove the dead moss.

What to Look for When Choosing Moss Killer?

To choose the best moss killer you must consider several factors.


Firstly, is it a seasonal product or can you use it at any time? Some items can only be used during specific months, and you may only be able to use them once or twice per year for best results.

Next, you should look at the safety of the lawn fertiliser. Some products are children and pet safe, whereas others can be harmful. As a result, you should assess your situation and consider which would be the most practical to use.


Also, you should consider aftercare. Most moss killers simply kill the moss but do not degrade or remove it. As a result, you may have to rake the grass afterwards to remove the dead moss. Consider if you don’t mind doing this, or if you have any physical ailments that may prevent you from raking.

Action Time

Finally, you should look at the action time of the killer. Some moss killers work within a few hours, whereas others may take a few weeks to work fully. Also, moss killer and weed killer combinations may take longer for the best results. This depends on how much time you have, what season you use the killer during, and how quickly you want to remove the moss.


If you want to keep your garden looking fantastic, and protect your grass, using the best moss killer for lawns is a great idea. Any one of these best moss killers listed above should yield great results.

However, our choice for best lawn feed and moss killer is the Miracle-Gro Fast Green Lawn Food. This is a great fast-acting product that is safe to use and should yield results in three days. It has an easy applicator, and is one of the best moss killers that also strengthens your grass, and improves its colour.

Which moss killer is best for your lawn? Good luck in your search.
