A weed free lawn starts with regular lawn maintenance such as scarfing and aerating the lawn, weed and feed in spring and autumn, this all helps, however, one way to deal with weeds at any time of year, especially leafy weeds, is by using a concentrate or ready to use lawn weed killer you can spray on, either the whole lawn or spot weeding

If you have weeds causing mayhem on your lawn, you’re are not alone. There are many ways to control the weeds on your lawn. Non-chemical options are to remove all the weeds by hand you a weed puller is a good idea and more importantly treating your lawn yearly to keep it nice and healthy which will help to reduce the weeds on the lawn in the long term. We have a good article on controlling moss on lawns here too.

If your lawn is particularly weedy and manual weeding is not an option, there are a selection of what are known as ‘selective lawn weedkillers on the market’. These weedkillers can be applied and will kill the weeds but not the grass as they generally only target leaf weeds such as white clover, black medick, lesser trefoil, daisy, dandelion, plantain and common mouse-ear.

If you scarifier your lawn in spring and autumn as well as weed and feed the lawn with a granular feed using a spreader then your on the right track to keeping your lawn weed-free.

However, if you have a problem with dandelion or similar then applying a lawn weedkiller is probably the best answer. Below is what we highly recommend using, formally known as Verdone, it’s now called Weedol lawn Weedkiller and it probably the best weedkiller currently available for treating lawns.

Best Pick

Weedol Lawn Weed Killer Concentrate Liquid
Weedol Lawn Weedkiller is perfect as it can be used on new lawns (from 2 months old) without risk of damaging a new lawn. It has proven effective in dealing with a wide range of weeds including the most common weeds found in lawns including black medick, lesser trefoil dandelion, daisies and clovers. It is easy to apply easily with a watering can with a fine hose but we recommend using a sprayer as its less wasteful. It is also an affordable weedkiller while still being very effect which is why it’s probably the most popular weedkiller sold for lawns currently available.


Miracle-Gro Evergreen Complete 4 in 1
Miracle-Gro Evergreen Complete 4 in 1 is a lawn feed but is also specially formulated to control both moss and weeds in case you are facing a double infestation. The granulated weed killer and feed for lawns comes with a set of detailed instructions on how to use the product. Using a spreader to cover the lawn with the mixture, this product covers an area of 200m2. If you have a large lawn to work with, this product will give you good value for money. We recommend setting up a yearly schedule to use this product every year. When you see perfect lawns and even golf courses, they nearly always use this product or similar. Just don’t try and apply it by hand as you can easily burn the lawn, use a spreader as they also make it much easier and there not to expensive either.

Best ready to use weedkiller

Resolva 3 Litre RTU Extra Lawn Weedkiller
Our top pick for the best ready to use lawn weed killer is none other than the Resolva 3 Litre RTU Extra Lawn Weedkiller, it comes ready to use with a spray head. The weed killer covers an area of 120m2 and it is affordable. For those who want a herbicide that comes ready to use, this product is one to look out for. It will leave your lawn green and healthy from those pesky weeds.

Which weeds can they control?

They are selective in that they kill broad-leafed weeds. Not all weedkillers kill the same types of weeds as it will depend on the active ingredients. Many of them will kill the most common such as buttercups, daisies, dandelions, clovers, docks as well as many more. If you know which weeds you have on your lawn, it’s always a good idea to choose weedkiller which specifies that it controls those types of weeds.

Types of lawn weedkillers – Concentrates vs Ready to use

Weedkiller concentrates offer better value for money but ready to use offers convenience but are perfect if you only have a small amount of mixture.

Weedkillers can be purchased ready-mixed or as a concentrate that you mix yourself in a sprayer. The concentrate option is usually much cheaper and ideal for larger areas where you may need to treat your whole lawn.

If you just have a few weeds and want to spot weed, just spraying the weeds and not the whole lawn or don’t like the idea of mixing your own from concentrate, then ready to use sprayers are the way to go, however, remember this is usually much more expensive.

If you do want to buy the concentrate and want to know which garden sprayer we recommend, we did a roundup of the best garden sprayers which you can read here.

Top 5 Best Lawn Weedkiller Reviews

1. Weedol Concentrate Lawn Weedkiller

Our Recommended – Lawn Weedkiller Concentrate

Weedol 1 litre Lawn Weed Killer Concentrate Liquid

Probably one of the best lawn weedkillers available, formally produced by Scotts Miracle-Gro but its now branded as Weedol buts it the same great mixture and very effective.

Simply mix with water at the required rate and you are good to go. It is very effective and is season long meaning you only need to apply it once in most cases.

It is available in 250ml, 500ml and a larger 1 litre quantity, with the larger one covering 667 Sq.m which is ideal for larger lawns. What makes this weedkiller one of the best is that it contains 3 types of herbicide which means it kills a large selection of broad-leafed weeds including:

Dandelions, Daisies, Clover, Plantain, Common Mouse-Ear, White Clover, Black Medick, Lesser Trefoil.

The weeds start to die within a few days, they will start to wilt and it then takes around 4-6 weeks before they turn brown and turn to mulch which in turn adds nutrients to the soil feeding the grass. Sometimes this process happens a lot more quickly but as a guide around 4 weeks is normal.

Two others advantages are that you can apply it to lawns over two months old, most other weedkillers it is a minimum of 6 months and once dried it is safe for pets and children to go onto the treated area.

Overall this is what we would recommend, get yourself the concentrate and mix with water, it works out much cheaper and is easy enough to measure out and mix in a sprayer. Then you can just mix a little as and when you need it.

It is recommended to mix the product with 1.5-3 litres of water depending on how intense the infestation is. The six tubes all together can cover an area of 90m2 which is roughly around 9 car parking spaces which should give a good idea of what area you can cover.

This product would be appropriate for those with small lawns that need occasional weed killing. It is sold at an affordable price and you get adequate instructions to get the best results.

Ready-mixed weedkillers

Ready-mixed weedkillers are ideal for spraying individual weeds and are ideal for spot weed killing. The advantage of doing this is that you reduce the number of chemicals used on your lawn and the less you can use any types of chemicals in the garden the better.

You can now purchase larger, ready to use weedkillers that come with a sprayer attached that uses a pump-action for spraying larger areas without the need for mixing it yourself which is handy but as mentioned this does work out more expensive but it means you don’t need to do anything but spray the weeds.

General tips when applying lawn weed killers

  • Try not to apply weedkiller onto a new lawn until they are at least 6 months old, if you really need to you can spray Weedol lawn weedkiller after 2 months but the longer you can wait for, the better.
  • Apply when the weeds are actively growing, this is usually between April and September. oF Like all weedkillers if you apply then they are not growing, it will result in poor results.
  • Apply ideally then the soil is moist but the weeds and lawn are dry. Check the weather forecast as ideally, it should not rain for at least 24 hours after the application for them to be effective.
  • Lawn weedkillers will not kill seeds so apply a second time around 6-8 weeks after the first application to kill new weeds or stubborn weeds that need more than one application. Most weedkillers will say only one treatment is needed but this is not always the case and a second dose can finish off the last few weeds and seedling.
  • If covering larger areas, use concentrate as this will be cheaper and easier to apply.
  • Do not spray when windy as they can kill shrubs, trees and plants if spray drifts onto them, this goes for all weedkillers.
  • Do not mow the lawn 3 days before or 3 days after the application of lawn weed killers.


When do you apply weed killers to lawns?

The best time to apply weed killer is between late spring and early autumn. This is because the weeds are actively growing and therefore it will be easier for the weed killer to be absorbed. Once the weed killer is absorbed the plants die off without harming the grass.

Can you use any weed killer on a lawn?

No, it depends on the type of lawn you have and the intensity of weed growth. There are weed killers that may harm new lawns and therefore, they are discouraged. Most weedkillers not sold as weedkillers for lawns will nearly always kill grasses which includes lawn grass.

Why don’t lawn weed killers kill grass?

This is because the herbicide is designed specifically to kill off weeds or moss that is competing for water and other nutrients. The herbicide is absorbed into the plants through the leaves killing off the roots.

How do you apply weed killer to lawns?

In many cases, manufacturers provide instructions on how to use their products. Whether you need to dilute the mixture or it comes ready to use, the idea is to spread the mixture over the weeds. This is especially targeting the leaves where the absorption rate is high. Some weedkillers come in granular form and are best applied with a lawn spreader.

Our Final Conclusion

Keeping your lawn in good shape is important and that is why the kind of product you choose matters. That is why effective products like the Weedol Lawn Weedkiller which is our best pick has gained so much popularity.

If you prefer another brand, the Resolva Concentrate Lawn Weedkiller Extra is always a good option. Regardless of the product you select, make sure that it qualifies to be among the best lawn weed killers in the market. The health of your lawn will be the proof in the pudding.
