11 Best Weed Killers To Keep Your Lawn Looking Beautiful
In This Article
Maintaining a garden is no easy feat, there is a lot of effort that goes into having a beautiful and lush garden. But gardens can sometimes get infected by unwanted plants aka generally known as weed plants. Weed is not necessarily a “bad plant”, they are just plants in the wrong place. To avoid or to control their growth, you need the best weed killers that you can get. Weeds are quite stubborn and they grow back even after we pluck them from their roots and weed killers are one of the easiest ways to get rid of these plants.
Herbicide/weed killer is a substance that is extremely toxic to plants. Some types of weed killers have the ability to kill the weed internally down till the roots.
Types Of Weed Killers
- Contact Weed Killer: Just like the name suggests, these types of substances kill weeds or their parts that come in contact with it. It does not reach the roots of the weed, but it weakens them enough to stop them from growing at a normal rate. They are very effective and provide results faster than any other type of herbicide.
- Systemic Weed Killer: Unlike contact weed killer, these substances get rid of the weed from the root. When these herbicides are sprayed, they are absorbed by the leaves and stems which are then carried internally throughout the plant. This causes the weed to die completely along with its roots. The downside with this is that it takes a few days to show its effects.
- Selective Weed Killer: These substances are designed specifically to kill certain types of plants which leaves the plant you want to thrive, untouched.
- Non-selective Weed Killer: These substances are used when all plants, irrespective of their type are to be eliminated. They are majorly used in plantations like that of rubber, orchards, vines, and oil palm.
We have a list of the 11 best weed killers that will get rid of the weed from your garden and keep them thriving.

A Buying Guide To Choosing The Right Weed Killer
- Type of Weed Killer: At the beginning of the article we discussed the various types of weed killers. With that in mind, think which type will suit your needs more. If you know the kind of weed that is growing on your lawn, then you can choose something that is effective for that particular species. But, if you are not sure, then you should choose general weed killers for gardens and lawns.
- Effectiveness: Weed killers that have strong and concentrated formulas provide fast and efficient results in less time. Some solutions take a couple of days to show its effects and some do it in just a few hours and might cost a little more. Depending on this, you can choose the one you think fits best.
- Safety: Since weed killers have harmful chemicals, they can be dangerous not only to plants but for humans and animals too. If you have kids or pets at home, then safety becomes very important. The chemicals could have adverse effects on the skin and much worse if consumed. There are organic and kid-friendly weed killers that are less severe and safe to some extent to be used around kids and pets. But if you do not want to choose organic and buy something that uses chemicals, make sure that you store it out of their reach. When it is sprayed in an area, do not use that area for a few hours or days depending on the brand that you chose.
- Ease of use: When you use a weed killer, you always try to reduce the amount of manual work to dilute the solution since it can be harmful or you might just not know how to do it. Some brands offer ready-to-use weed killers that do not need to be diluted and also come with a weed killer spray for ease of usability. If you know your way around these solutions and are okay with diluting them manually, then you can choose the other ones.
Just like the wise Ian Malcolm once said— life finds a way. Plucking the weeds from the roots is not enough, they come back. To stop these weeds from growing back, any one of the weed killers from the above list will help you get rid of them. Now, that you know what are and how to choose the best ones, it is over to you as to which one you buy. So, go ahead, click on the product that you think suits best for your needs, and buy away!
