The Best Weed Killer For Lawns – For controling broad leaf weeds
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, specially 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, its now called Weedol lawn Weedkiller and it probably the best weedkiller currently available for treating lawns.
Our favourite choice when it comes to controlling weeds on a lawn, specially dandelions, daisies and clover but it also controls many more weeds and is super easy to apply with a sprayer.
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.
Our Recommended – Lawn Weedkiller Concentrate
Weedol Concentrate Lawn Weedkiller
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 guide around 4 weeks is normal.
Two others advantages is 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.

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 amount 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.
Our Recommended Ready-to-use Lawn Weedkillers
Weedol Ready To Use Lawn Weedkiller
As mentioned above, this is one of the best lawn weedkillers available, it comes in a ready to use in a 800ml spray container and can be purchased either as a single carton or sometimes in a twin pack..
Ideal for smaller applications where the concentrate would be too much, spray individual weeds or small patches of weeds with ease using the trigger gun included.
If you just have a small lawn with a few weeds this is probably the best way to go.

General tips when applying lawn weed killers
- 1Try 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 the better.
- 2Apply 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.
- 3Apply 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.
- 4Lawn 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 them last few weeds and seedling.
- 5If covering larger areas, use a concentrate as this will be cheaper and easier to apply.
- 6Do not spray when windy as they can kill shrubs, trees and plants if spray drifts onto them, this goes for all weedkillers.
- 7Do not mow the lawn 3 days before or 3 days after the application of lawn weed killers.
There are many weed killers available for lawns from lots of different brands but Weedol Lawn Weedkiller does seem to be the most effective at killing the largest range of broad-leafed weeds and has many advantages to others available on the market which include quick but longer lasting effectiveness, can be used on new lawns over 2 months old and once dry children and pets do not need to be excluded from the treated areas.
It is available in many sizes, in concentrates and ready to use carton and really does tick all the boxes for an effective weedkiller to use on lawns. Don’t be tempted by cheaper products, you will only find yourself applying multiple applications and find that it is not as effective on some weeds.
