4. Lilly Miller Moss Killer For Lawn

Lilly Miller Moss Killer For Lawn

Hose ‘n Go Moss Out! For Lawns is the fast, easy way to kill moss in lawns.

Pros & Cons

It helps the grass absorb nutrients

It is easy to use because of its liquid form

Best for killing moss within hours

It can leave stains

Overview & Review

The Lilly Miller brand also makes liquid ready-to-spray moss killers for people who put ease of use above anything else. However, ease of use here does not imply that this product is inferior to their granular product or will not produce good results.

Once sprayed, the formula starts working immediately, and you will see the moss turning brown and black in a few hours. And since the recipe is ready-to-use, you do not need to mix it or anything, and it easily attaches with a garden hose sprayer.

As for the size of the product, it is a 32 oz bottle that can treat an area of about 500 square feet.

However, please remember that the product is not designed for hard surfaces, as it can leave stains and must be used in the correct dosage to produce desired results.

Scotts Turf Builder with Moss Control kills moss, and at the same time, it feeds your lawn.

Pros & Cons

Prevents future moss growth

It kills moss in a few days

Ideal for all types of grass

It helps your lawn absorb more nutrients and water

Easy to use

Available in two size options
Not available for purchase in some states

Overview & Review

There are instances when moss is not the only issue plaguing your lawn.

For example, your grass might also be thinning in places that will create even more favorable conditions for the moss. Here is where Scotts Turf Builder With Moss Control could come in handy.

The 2-in-1 formula of moss is designed explicitly for lawns with thin turf and lots of moss. It first kills moss and then feeds the yard, which has been deprived of nutrients due to the competition from moss.

The product is granular and can be applied to the lawn using a spreader. However, you will need to water afterward to activate the formula.

Furthermore, I highly recommend that you use Scotts Turf Builder With Moss Control during the active growth season so that your grass can make the most out of it.

6. Lilly Miller Moss Out For Roofs And Walks Concentrate

lawn moss killer

Lilly Miller Moss Out is a potent liquid product for removing moss from your roof, sidewalk, and patio.

Pros & Cons

It has a non-staining formula

It works well in shaded spots

It easily gets to hard-to-reach surfaces

It acts quickly and kills moss in hours

It is very affordable
It will not work well if the moss is dryIt only covers about 500 square feet

Overview & Review

Your lawn is not the only place that gets invaded by moss. It can also attack hard concrete surfaces such as your home’s roof, patio, and driveway. Unfortunately, you cannot use any granular moss-killer product here and will have to use a liquid product instead.

However, which product works best for solid surfaces to remove moss? 

In my experience, lawn moss killers can kill moss on roofs and patios, but you would be much better off with a hard-surface targeted moss-killer product.

An excellent example of such products is Lilly Miller Moss Out For Roofs And Walks Concentrate. Its formula contains zinc sulfate instead of iron sulfate, which is present in regular moss killers. And zinc sulfate does not stain hard concrete surfaces.

Furthermore, the formula includes ammoniated soap of fatty acids, which allow the moss-killer to seep into hard surfaces killing the moss once and for all.

7. Wet & Forget Mildew Cleaner

Wet & Forget Mildew Cleaner

Wet and Forget Outdoor Cleaner makes treating moss, mold, mildew, and algae stains quick and easy.

Pros & Cons

It can cover up to two thousand square feet

It can spray areas up to 30 feet high

It is easy to use and needs no preparation

It also works well as a cleaner and stain remover

It produces long-lasting and satisfactory results
If applied to plants, it can be hard to take off

It sometimes leaves a drippy slime behind

It takes longer than other products to kill moss

Overview & Review

The following product in our list is Wet & Forget Mildew Cleaner. Its 2-in-1 formula allows it not only to kill algae, mildew, mold, and moss from hard surfaces but also lets it clean stains.

Also, like most stain cleaners on the market, it has no bleach; even better, after its application, you do not need to scrub and rinse surfaces when applied.

Furthermore, it is non-scented, and according to the brand, it has an unlimited shelf-life. 

The product is available in several different sizes, and you can get anyone depending on your use and requirements.

However, the formula is toxic, and you should not spray it close to wildlife, lakes, and ponds. For best results, apply the product when no precipitation is predicted for a few hours and ensure the temperature is above 55 degrees Fahrenheit.

8. Scotts MossEx 3-in-1 Ready-Spray

Scotts MossEx 3-in-1 Ready-Spray - lawn moss killer

The fast-acting Scotts 3-in-1 MossEX Ready-Spray kills moss, algae, and lichens within hours.

Pros & Cons

It is based on a no-stain formula

The product is affordable and easy to use

It works quickly and kills moss within a few hours

Performs remarkably in outdoor settings

It can be used at any time of the year
It only covers about 500 square feet

It cannot be used when the temperature is above 85F

Overview & Review

The last moss killer on our list is another one from the Scotts. However, unlike the previous two products mentioned in this list, this one is designed for lawn use.

Scotts MossEx 3-in-1 Ready-Spray is very easy to use too. All you have to do is attach the container to a hose and spray. It can be used at any time of there year, and it does not stain.

However, please remember that for best results, you should spray it during the active growing season of your lawn grass and not spray it when it is too hot outside. It is because the ferrous sulfate-based formula of this product can cause lawn burns.

Also, unfortunately, the product covers only about 500 square feet. So, if you have a large lawn or need to treat a larger area, you will need to buy more than one.

How To Use A Moss Killer Correctly?

lawn moss killer

Always follow the manufacturer’s guidelines when applying a moss killer on your lawn.

The first thing you need to know when using a moss killer in your yard is that it should be done at the right time of the year. While you can kill moss on your lawn any time of the year, the spots left behind from the moss removal will need to be reseeded.

Therefore, if you time moss removal treatment with the active growing season of your lawn grass, you will be able to reseed it immediately. The practice will also save you from worrying about weeds or moss returning to the cleared spot.

Furthermore, if the moss is very thick, I highly recommend that you dethatch your lawn before applying the moss killer. It will ensure that the chemical reaches the lawn surface and kills any moss hidden beneath the grass blades.

Finally, once the moss dies and turns brown or black, you must remove it from the law.

You can do it with a simple garden rake. Once you remove the moss from your lawn, you can either throw it in the trash or compost it at home.

Things To Consider Before Buying A Moss Killer

lawn moss killer

Moss killers that work great on lawns do not produce the same results on hard concrete surfaces.

Even though all the products mentioned above are great and work wonderfully at killing moss in yards and homes, they are not all perfect. Some are better suited for one application than the other and vice versa. I am trying to say that depending on your use and needs. 

You might get more out of one product than the other.

Therefore, here I have compiled a few things you must remember before buying a moss killer on your lawn, root, patio, driveway, and home.

Type Of Moss Killers

Depending on where you want to remove moss in your home, various moss killers are available. These moss killers have different chemical compositions to work effectively on targeted surfaces. It would help if you bought a moss killer that will act on the material or surface you need to clean to avoid potential damage.

Moss Killer For Lawns

The active ingredient in most lawn moss killers is ferrous sulfate. However, if you have thin turf, you might want to use a moss-killer containing fertilizer.

Moss Killer For Concrete Surfaces

The active ingredient in moss killers designed for concrete surfaces such as patios and driveways is often zinc sulfate. It is because the iron in lawn moss killers can rust over time and leave stains if used on hard concrete surfaces outside.

Moss Killers For Roofs

Moss killers designed for lawns and concrete surfaces often contain acidic compounds. These acidic compounds can cause significant damage to roofing materials. So, when you buy a moss killer to clean a rood, ensure it has neutral pH.

Liquid Vs. Granular Moss Killers

Granular moss killers often come in large packaging and can cover vast areas.

As you know by now, moss killers come in two forms: granular and liquid.

Liquid moss killers are easy to use and come in ready-to-use form. However, they are often shipped in small quantities and cannot be used to treat large areas and big yards.

Here granular moss killers come in handy. They come in large shipments and can be spread over a large area to kill moss. However, granular moss killers are somewhat cumbersome to use in yards compared to liquid and ready-to-spray moss killers.

Size Of The Lawn

As mentioned earlier, liquid moss killers are often shipped in ready-to-use diluted forms that cannot cover large areas.

So, if you have a large lawn, you should buy concentrated liquid moss killer or moss killer granules that you can spread on your property.

Ease Of Use

Lastly, consider the ease of application when buying a moss killer. Caring for a lawn and keeping a home free of moss can be tedious, and you do not want to increase your work. So, go with liquid lawn care if ease of application is your priority.

Final Thoughts

If you are concerned about moss growth on your property, investing in a good moss killer is something you will not regret. However, when buying a moss killer, please keep in mind the things mentioned above so that you do not run into any issues.

Lastly, moss-killer products are temporary treatments. They are not permanent solutions.

So, unless you get rid of the thing causing moss growth, moss will come back to your property sooner or later, no matter how harshly you treat it.

Frequently Asked Questions (FAQs)

What kills moss permanently?

If you want to kill moss once and for all, use a product based on ferrous sulfate. However, it will return unless you remove the things that cause moss growth.

What kills moss the fastest?

The fastest way to kill moss is to use vinegar and water solution. Mix equal parts of vinegar and water in a bottle and spray it on moss. It will die in a few hours, and you can remove it.

What kills moss naturally?

You can use many things to kill moss naturally without using any chemicals. Some examples include baking soda, vinegar, and horticultural oils.

How do you stop moss from growing back?

If you want moss to never grow again on your property, determine the cause and conditions for its growth and fix them or eliminate them from your property.

Does lime kill moss?

Lime can be used to kill moss as it increases the pH of the soil and makes it inhospitable to moss. However, the rise in pH can also be detrimental to your grass.
