Best weed killer for lawn buying guide

Weed killers designed for use on lawns are not only amazing when it comes to killing dandelions, clovers and other troublesome weeds, they also make it easier to dig and remove weeds by hand.

However, when you buy a lawn weed killer, there are some really important things to consider when shopping.

Some of them are listed below. These points not only help you to find the best product for your individual needs, but also ensure that your lawn looks beautiful and healthy all year round.


The first thing to think about is which weed species infiltrate your lawn. By determining if you have dandelion, crab grass, wild violet, clover, or any of the over 400 types of grass weed identified, you can ensure that the weed killer you buy effectively kills it.

Fortunately, most weed killers are designed to destroy multiple weeds, and some are even designed to control up to 250 different species. This is a good thing to watch out for if you are not 100% sure of what is growing in your lawn, or if you have several types of weeds strewn across your grass.

Existing lawn

It is one of the most important things to consider to ensure that the weed killer you select does not affect your existing lawn. Some weed killers are so powerful that they not only kill the weed itself, but also completely destroy the grass that surrounds it.

All of the weed killers selected above have been specifically designed for use on weeds that grow on lawns but do not affect the lawn itself.

If you are unsure whether your weed killer is suitable for use on grass or not, do not hesitate to contact the company and find out. Repairing a damaged lawn can take years of hard work and maintenance. So it's not worth taking the risk and you could potentially do irreparable damage to your existing lawn.

Targeted killing

Now that you have found out what type of weed it is, you are 100% sure that your chosen weed killer can be used safely on your lawn. It is time to examine carefully how the weed killer works.

Almost all weed killers available today are designed to penetrate the leaves of the weed and work their way through the plant to the roots. Then she continues to work until the weeds are absolutely dead.

This is a preferred method among many gardeners, as it prevents weeds from ever growing again, since a plant with a dead root system cannot produce life at all.

One thing that many people overlook when it comes to weeds is that they tend to sow themselves everywhere. This means that you may have been late even if you removed the weeds from the roots and the seeds for next year are already there.

With that in mind, it's also a good idea to look for a lawn weed killer that will help prevent further outbreaks and kill existing weeds. This is achieved by creating a barrier between the ground and the grass that suffocates all seeds and prevents them from germinating.

If you take this preventive measure, you will also save time and energy next year and you will find that there is significantly less weed scattered and the perfect appearance of your lawn ruined.


You also need to spend some time figuring out how easy it will be to prepare the weed killer, and working out the right calculations for your room can have a real impact on its effectiveness. Mix it too much and you could damage your lawn. Mix it too weakly and it will have almost no effect on your weeds.

Fortunately, this uncertainty can be reduced in a number of ways. The first option is to buy a lawn weed killer that is already prepared for you, so you don't have to worry about mixing. It can simply be applied to the lawn straight from the bottle.

However, if you choose a weed killer that needs to be mixed with water or sprinkled over a lawn, make sure the calculation instructions are implicit. Most of the time, these are on the packaging itself. However, some brands have gone one step further and give you details about an app that you can use to ensure that you are using the perfect amount.


Weed killers are usually either liquids or core-like granules, and each has its own method of application.

The most liquid variety that is easiest to apply to your lawn is the liquid variety. This is because they can be mixed with water in a garden sprayer and easily sprayed over the lawn. This also gives you the ability to directly control weeds or throw them wide to get wider coverage.

Weed killers, which are supplied as granules, can be spread by hand on a lawn. However, it is often easier to pour the desired amount into a seed distributor and then walk across the lawn. This gives you better coverage and you can also make sure it touches the floor when you step on it.

Some weed killers are also easily formulated in a bottle that is simply attached to a hose. This is by far the easiest option, as not only is there no need to calculate quantities, you also don't have to search for your garden sprayer or seed distributor in your shed.


It is also important that you get a weed killer that gives you adequate coverage for the size of your lawn. The last thing you need is that when you are in the middle of the job, treating part of your lawn and the other half covered with weeds, you will no longer have it!

Cover size varies from product to product, but most lawn weed killers offer between 10,000 and 20,000 square feet in a single application. This makes them perfect for weed control on larger lawns, but is also an economical choice for smaller gardens as you can use them over and over again.

Before you make your purchase, go to your yard with a tape measure and find out how much weed killer you need to make your lawn look beautiful and weed-free.

Additional functions

While weed killers aren't particularly expensive, it's always a good idea to see what other features you can get for your money, and you'll be surprised to find some lawn weed killers have thought about things you might otherwise miss.

One of those things is food. Killing weeds is only half the battle. In order for your grass to become strong and healthy, it must be fed regularly, especially in the summer months.

A weed killer that not only kills weeds but feeds the grass at the same time will encourage your existing grass to grow into any weed-stained stains and also help your lawn build a strong root system that contains weed seeds will have difficulty germinate and grow.

Another very useful feature to watch out for is rain protection. This is a little more confusing to get your head around, but it essentially means that if it rains shortly after you apply your weed killer, it doesn't wash away or become excessively diluted, giving it time to be effectively exposed to adverse weather conditions without working.
