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 in 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.

When setting out to buy a moss killer, you have to consider some factors. But many customers do not know what to look out for and end up with unsatisfactory products. This has nothing to do with the quality of the product but on whether it best suits your needs. So, before you set out to pick a moss killer product, be sure to list these questions on your checklist;

What Type Do I Need?

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.

Your choice should depend on how much convenience matters to you, how 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.

While most powders are termed ideal for all-purposes, it takes a certain level of skills to brew the perfect mix. And while many 3/4-in-1 products are beneficial, they're usually on the steep price end. Plus, you might eventually discover you never really needed the multi-purpose feature. So, make sure you do before you pay for it. And if you don't, pick a more specific product that suits your requirements.

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 surfaces like tarmac and concrete upon contact, causing discolouration. This is most especially when the product is wet. Look out for such warnings and go for hard surface-friendly products if this is important to you. You might end up spilling some over surrounding surfaces, so you need to be sure it won't be an issue.

Is Eco-friendliness Important to Me?

Though moss killers attack weeds 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 to the environment.

Some moss killers and weed feed even come with matter-decomposing bacteria and compounds that improve soil structure. Others carry new grass seeds for automatic reseeding. And there are some which do not restrict access to the lawn while still in effect.

These family-friendly moss killers are available in the markets around. And although not as fast as their harsher counterparts, they always give impressive results.

Understanding the Jargons.

Iron sulphate: a chemical salt often used as a fertilizer and acidifier to kill moss on alkaline soils.

Dicamba: a chemical herbicide used mainly on broadleaf and woody weeds.

Mecoprop or Mecoprop-P: a general use herbicide for controlling broadleaf weeds.

MCPA: an acronym for 2-Methyl4-Chlorophoxyacetic acid; a powerful and widely used herbicide. It is very selective and acts, especially on broadleaf weeds.

What are the Different Features?

Many people usually consider three handy features before purchasing moss killers. The first is its specialization. Most users go for all-purpose products more than specialized ones as they believe it gives more value for money.

They also think it is a wise investment, in case a problem arises on the lawn. 3-in1s and 4-in1s enjoy massive patronage because of this.

Another handy feature, usually considered by the vast majority is quantity. People prefer to get more at less cost.

This is why most users quickly purchase powder and liquid products because when mixed with water, you get more volume. This also proves to be cost-effective as they can cover more lawn area.

Moss Killer For Lawns Buying FAQs

Q: How to get rid of moss in a lawn

A: There are multiple ways to get rid of 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 tool to scrape the moss off hard surfaces. You can also increase the acidity of the corners and damp surfaces 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 branches create too much shade over damp areas in 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. This is because 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: Reseeding lawn after moss removal

A: The best way to reseed your lawn after moss removal is overseeding. To do this, you need to make sure you scarify around spring and autumn as these are the best periods for grass germination. You should also choose the right lawn seeds, preferably the same as the species already on your lawn. After that, ensure regular watering to guarantee seed germination and growth.

Q: What does a scarifier do?

A: A scarifier or lawn scarifier is like a mower with a reel and knife edges lined on it. It is used to aerate the soil and remove plant debris. Scarifiers are run over lawns to remove moss, sometimes even after eradication with moss killers.

Q: Can you scarify a wet lawn?

A: It is ill-advised to scarify a wet lawn. Doing this may result in uprooting the grass instead of just removing moss or thatch. If you have to water your garden, do it a couple of days before you scarify.

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

A: Iron sulphate is used as fertilizer on gardens, used to improve growth and green hue of plants. It can also be used as a moss, weed 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 method of preventing and controlling weeds and moss growth on lawns. It is also a good stimulant of grass growth and encourages greening.

Q: How to care for a lawn?

A: Regular watering, moss and weed control and fertilizer application are proper maintenance techniques. Rake up plant debris, thatch and moss to prevent re-growth. Also, use high-quality moss killers and lawnfeeds. And practice periodic scarification and overseeding, preferably in the fall or spring.

Q: When to weed and feed lawn?

A: The most appropriate time to weed and feed lawn is in early spring or late winter, before the growth season. This will not only wipe out the weed population before the growing season but will also sustain your lawn during that time.
