Best weed killer for your lawns in 2018 - How to Choose?
Please note from the beginning that some of the products are the best weed killer for lawns that are old and that you wish to remove altogether before replanting with a fresh new type. These types are also suitable for clearing a piece of ground of all weeds and unwanted vegetation before planting a brand new lawn. Other products are suitable for spraying onto an existing lawn that is infested with weeds. The weeds will be killed but the grass unharmed.
Before choosing what you think is the best lawn weed killer, the most important thing is to identify exactly what kind of weeds are growing in your turf. This will determine what kind of product you choose. You need to be careful about this, as choosing the wrong one, or using too strong a mix, can damage or kill the lawn as well. Some weeds are resistant to the chemicals, and will need to be sprayed more than once. Take note of whether the weeds are annuals, such as crabgrass, or perennials (more difficult to control) such as dandelions. Your local nurseryman or garden center will probably be familiar with the common weeds in your area. If you’re struggling with identification, just dig out a sample and take it into the shop for advice.
It’s also important, before purchasing the best weed killer for your lawn, to establish what you’re trying to achieve. Are you trying to prevent weeds from growing in the first place? (In which case you’ll need a “pre-emergence” herbicide, which is usually applied in spring.) Or are you trying to solve an already existing weed problem? In this case, you’ll need what is called a “post-emergence” herbicide. Some of these are selective and only target, for instance, broad-leaved plants, while others will kill anything green and growing. These ones, obviously, will not be the best weed killers for your lawn, but are best used on paths and edgings.
You’ll also need to decide whether to buy a concentrated herbicide- ideal for if you have a large area to spray, or a ready-mixed spray. These are best for small spaces.
What follows is a selection of five herbicides, one of which you may decide is the best lawn weed killer for your purposes. We’ll discuss the pros and cons of them all, so that hopefully at the end you’ll have a better idea of which one is most suitable for your needs.
Top 5 Best weed killer for lawns reviews 2018
Here are top 5 best weed killers for lawns in 2018:
1. Compare-N-Save Concentrate Grass and Weed Killer, 41-Percent Glyphosate
This is a very strong, concentrated product for use on most kinds of weeds. This is useful if you don’t know what type of weeds you are dealing with. It’s the best weed killer for lawn only if you are wanting to clear an area for a new lawn. You can use it for spot-spraying bigger stubborn weeds in your existing lawn, but you’ll need to be careful as it will kill any grass it comes into contact with as well.
It’s very useful for times when you have an old lawn that you want to replace that’s become full of weeds and old growth. You’d spray the entire lawn, and, once it had completely died (usually after about a week) you’d be able to remove and replant it.
The product is easy to mix up with the recommended amount of water, and a little goes a long way. This product is best used in warm, dry conditions when no rain is expected. However, after just two hours, if rain does fall or if the lawn is irrigated, the product will still be active. It’s also best to pick a day that’s not windy, to prevent the spray from blowing onto plants you want to keep.
Grass and Weed Killer can be sprayed on very easily using a tank sprayer device, or a hand spray with a trigger. (Don’t apply it with a watering can or irrigation system.)
One of the big disadvantages of the product is that it is non-selective, meaning that it will kill any plants that it comes into contact with, including your lawn. This means that it’s possibly not the best lawn weed killer when you want to preserve your lawn, but is certainly worth a try when you are clearing an area for new grass.

This amazing product is one of the best weed killers for your lawn as it kills many different kinds of broadleaf weeds on contact. This means that it will kill most weeds, but leave the lawn grass unharmed.
A little of the chemical goes a long way (you’ll only need about two tablespoons in four gallons of water to treat about a thousand square feet of lawn.) You’ll need to water the grass a couple of days before applying it, or else wait for rain. It’s important not to spray the lawn when conditions are very dry. After application, the grass shouldn’t be watered for a day and night, to give the product time to work before being washed off. It can be applied using a low-pressure type spray nozzle.
This lawn weed killer is made with a mixture of three different herbicides, so that it’s able to kill a wide variety of lawn weeds. It’s best to use it in spring, when the weeds are still small and haven’t established a foothold in the lawn yet.
