Moss Killer For Lawns Buying Guide

Having moss growing on your lawn destroys its appearance. A petrol lawn mower and cordless strimmer only trim the grass. They do not get rid of the moss at its root. A garden rotavator is used to prepare the land for planting grass and flowers, and will thus not be effective in separating the weed and moss from the mature grass.

To get rid of moss on your lawn, you need the right solution. Some weed killers and patio cleaners may eliminate moss, but your best bet is using a moss killer for lawns. We will guide you through choosing the right brand.

What Type Do I Need?

You need to consider several things. Moss killers basically come in three different forms; solid granules, liquid solutions and powders. The solid granules can be applied by hand or conventionally. This allows their easy application by watering can or sprayer, and they’re well-known for fast-acting and quick saturation of moss. Powders can be applied either dry or dissolved in water.

Our advice – your choice should depend on how much convenience matters to you, how small or large your lawn is, and how quickly you want results. While granules are the most efficient, powders are the fastest-acting while liquids are the easiest to apply.

Is Specialization Important to Me?

Most moss killers are multi-purpose; offering triple or quadruple action features. Usually, these revolve around moss killing, weed killing, lawn feeding and lawn greening. While this seems like an enticing offer, it doesn’t apply to all users.

Other moss killers are particular; usually offering one or two of these features- usually regarding treatment. Of course, all moss killers are lawn feeds as well, but some are most effective on moss than weeds.

What about Quantity?

The size of your lawn will determine how much moss killer you need. The trick here though is. Usually, you don’t need to buy a lot of it to meet up. Powders offer you more quantity when dissolved, as do liquids when diluted. Granules might be required in large amounts, but many products carry detailed instructions on a practical application to save costs.

Am I Bothered about Surrounding Surfaces?

Many moss killers are not hard-surface friendly. The chemical composition might react with hard surface areas like tarmac and concrete upon contact, causing discolouration. This is most especially when the product is wet. Look out for such warnings and search for hard surface-friendly products if this is important to you. You might end up spilling some over surrounding surface areas, so you need to be sure it won’t be an issue and avoid ones that stain hard surfaces.

Is Eco-friendliness Important to Me?

Though moss killers attack weed and moss but not the grass, this doesn’t automatically make them safe for other organisms. Many products carry warnings announcing its hazardous nature to aquatic life, human skin or even household pets.

So, if this is something you wish to consider, then organic moss killers should be your choice. Many are made purely of natural ingredients and components that are very safe for the environment.


Q: How to get rid of moss in a lawn

A: There are multiple ways to remove moss from lawns. The most effective way, however, is to use moss killers, which are available in different forms. You can also employ cultural practices such as raking up plant debris, improving soil drainage and reducing watering. You can also make a homemade moss killer with water and dish soap.

Q: How to get rid of moss on the path?

A: You can use a scraping gardening tool to scrape the moss off hard surface areas. You can also increase the acidity of the corners and damp areas on the path. For this, apply undiluted acetic-acid vinegar (20%) can be used in practical quantities with a sprayer. Saturate these corners and areas to increase the soil acidity. If you notice any trees or branches create too much shade over damp patches within your path, cut them off.

Q: When to apply moss killer?

A: For a more effective result, it is advised to apply moss killer either in late winter or early spring. The cause of this is – moss releases reproductive spores during the spring season. Applying moss killer at this time would ensure they never make it to the growing season.

Q: What is iron sulphate used for in the garden?

A: Iron sulphate is used as lawn grass fertiliser on the garden, used to improve growth and green hue of plants. It can also be used as a moss and worm killer on garden soils.

Q: What does lawn sand do?

A: Lawn sand is a combination of fine sand, iron sulphate and ammonium sulphate. It is a very effective way of preventing and controlling weeds and moss growth on lawns. It is also a good stimulant of grass growth and encourages green.
