Are you tired of having the lawn constantly infested with weeds? Don’t worry, because you’ve come to the right place.
As you may already know, I’m very invested in gardening and everything garden-related. So I know precisely how annoying it can get to watch the lawn you spent blood, sweat, and tears grooming suddenly acting up and getting overrun with weeds.
These atrocious weeds are not only aesthetically displeasing but also have the ability to destroy your plants and grasses. If that wasn’t bad enough, once these weeds take hold, they tend to spread like wildfire, making the task even more challenging.
But don’t worry, because I’m about to make your life much easier with this detailed guide of the 5 best weed killer for lawns. Each of the products in this guide come tried, tested and emphatically recommended by me.
So without wasting any more time, let’s get started!
Top 5 Weed Killer for Lawns
1. Ortho WeedClear 0447805
The Ortho WeedClear 0447805 is a revolutionary product that can kill different kinds of weeds in lawns without harming the grass. It comes packaged in a spray bottle of 32oz that can cover and treat over 5000 square feet of property at one go.
Product Highlights
One of the very best aspects of this weed killer spray is its fast-acting formulation that shows results in just one application. It’s a ready-to-use formula that comes in an easy spray applicator. All you have to do is attach the sprayer to your garden hose and turn on the water. Hence, this is not only a very efficient and robust weed-killing formula but is also convenient to apply.
One bottle of this product can be used to treat over 5000 square feet of lawn and on various grasses, including Bermudagrass, Buffalograss, Zoysiagrass, Fescues, Kentucky Bluegrass, and Ryegrass.
What’s more, this spray does not harm any of the lawn grasses it is applied on but instead attacks the roots of the weeds found amongst these grass. The chemical effectively kills over 200 types of weeds, including but not limited to foxtail, crabgrass, dandelion, clover, and chickweed.
If all the above wasn’t enough, the potent formula of this chemical also makes it rainproof in just one hour after application. It is recommended to use this product during spring and fall as the weeds are young and thereby their growth is more active then.
What's There To Like About It?
I love how Ortho WeedClear kills the weeds along with the roots without causing any actual harm to the grass on the lawn. This formula is not only very potent but also rainproof, allowing it to work its magic on the lawn in just one application.
Unlike most other weed killers, this one is not saturated with harmful chemicals and hence is user-friendly and safe to use around kids and pets. However, it’s still better to keep your children and pets off the lawn right after using it for optimal effectiveness.
What's There Not To Like About It?
While this is a great weed killer for lawns, I’m not as confident of the effectiveness of this product for killing weeds on flower beds. Even whilst killing lawn weeds, this product leaves the remnants of the dead weed, which must be removed by hand.

What's There Not To Like About It?
Although very effective, users are advised not to allow any person or pets to enter the treated area until it settles properly. It is also suggested not to be applied to newly seeded lawns until after the 4th mowing, which means you cannot use this for controlling weed in new lawns. Also, as this weed killer is structured like fertilizer, it is not rainproof, which is somewhat disappointing,

Product Highlights
This pre and post-emergent herbicide controls and curbs many types of broadleaf weeds and woody plants depending on the right amount of application. The product itself constitutes a liquid concentrate in a low volatile amine form.
For this reason, it comes with particular application instructions that one must thoroughly follow. According to these instructions, you’re supposed to mix 2 to 3 tablespoons of this concentrate in 3 to 5 gallons of water to cover an area of 1000 square feet.
If you’re looking for a herbicide to treat ornamental turfs like pastures, golf courses, parks, rangelands, lawns, and other non-crop sites, then this might be the weed killer for you. You only require 1 to 4 pints of this concentrate to cover an acre of land.
However, instructions also mention that you should ideally apply this in late January or February to avoid spring and summer temperatures. It’s also preferable to apply this mixture with a low-pressure sprayer that has a fan-type nozzle.
What's There To Like About It?
This herbicide is absolutely ideal for covering extensive pieces of land and is highly economical to invest in compared to its other counterparts. Only 2-3 tablespoons of this concentrate mixed in 5 gallons of water are strong enough to cover up to 1000 square feet of land.
Moreover, the concentrate takes a maximum of two weeks to show results and kill all forms of broadleaf and woody weeds, including poison ivy.
What's There Not To Like About It?

Buyers Guide
There are many factors that you must consider before deciding which weed killer is the perfect one for you. So in this buyer’s guide, I have tried to detail every significant factor that might help you make this decision!
1. Types
There is a rather large variety of weed killers available in the market, and each of these types function in their unique ways. Depending on how they function, you can choose the one that works best for your personal needs.
Pre-emergent weed killers, for starters, kill weeds before they actually grow. So these products are more of a preventive measure than anything else. On the other hand, post-emergent weed killers need to be applied to weeds that are already growing on your lawn.
Within the umbrella of post-emergent weed killers, we have various other types, namely - selective and non-selective herbicides, contact, and systematic. Selective herbicides only target and kill a specific species of plants.
This species will be mentioned in the bottle of the herbicide you buy. Non-selective herbicides can kill any plant in your path. Hence these must be used carefully, so you don’t accidentally kill the entire garden.
Then we have the contact weed killer, which only kills the part of the weed it is applied on. As opposed to this, we have the systemic weed killer that makes the weed absorb it and then disintegrates it from the root.
2. Coverage Offered
Different weed killers come packaged in different sizes and hence have different coverage in terms of square feet. Most weed killers come in liquid concentrate forms, which require to be diluted with water. Thus, this increases the volume and coverage of the herbicide drastically.
3. Organic vs. Inorganic
The choice between buying an organic and inorganic weed killer is mostly a personal preference. Organic weed killers are made of all-natural ingredients and hence very safe to use and environment-friendly, but they also tend to be slightly less potent and more expensive.
On the other hand, inorganic weed killers tend to have volatile chemical formulations but work more efficiently. Hence, you will need to decide which of these factors are more vital for you according to your specific needs.
4. Ingredients
If you’re looking to kill only specific weeds in your lawn, make sure to look out for some potent chemicals such as Glyphosate and Imazapyr. These are considered non-selective and systematic, hence killing all plants they come in contact with.
5. Resistant to water
A water-proof weed killer means that it is rainproof. Imagine a situation where it starts pouring shortly after you applied herbicide all over the lawn; then your efforts might all just go in vain. But a rain-proof and water-resistant weed killer doesn’t allow that to happen.
Frequently Asked Questions
Most weed killers available in the market today can last for years. However, this also depends on where you store the products. It is critical to keep all your weed killers in a cool and dry place for optimum durability and performance.
If the weeds have truly taken over the entire lawn, you may need to apply the weed killer more than once to get rid of them. It’s always ideal to check the label for your manufacturer’s recommendations regarding this, and keep in mind that most herbicides are only meant to be used a few times every year.
It’s safe to say that any weed killer is unsafe for your children and pets. So if the herbicide does not explicitly mention that it is safe to be around, then it’s better to assume that it is dangerous for pets and kids.
My Final Recommendation
So with this, we come to the end of our guide for buying the best weed killer for lawn. It is absolutely essential to research well before making a decision regarding which herbicide to invest in.
This is especially important for weed killers because of the various types and potent chemical formulations they are freely available in. After all, you only want to get rid of those pesky weeds and not the entire garden!
Before I sign off, I just wanted to mention two of the weed killers that have my heart. The ECO Garden PRO is one of my favorite non-selective weed killers and is perfect for anyone with an environment-conscious bent of mind or a big family with pets.
However, for more extensive and selective lawn maintenance, Southern Ag 00203 is the one for you. This gives you acres of robust coverage at very economical rates. I hope this guide has helped you out and made your decision-making process just a little bit easier. So, see you next time.
But until then, happy gardening!
