Roundup Ready-To-Use Weed & Grass Killer B00132E6YU – Best Overall

Roundup Ready-To-Use Weed & Grass Killer B00132E6YU

With its history dated back to 1976, Roundup has been in the grass control business for nearly half a decade, constantly pitching its own formula against several potential rivals. Strong, powerful, challenges even the toughest weed – that is how the brand manages to last so long in the competitive market. And this ready-to-use solution is where you can meet all those qualities.

The grass killer gets all the invasive weed frustrates you to no end out of sight, from leaves to roots. Going further than only crabgrass, which swings by every single year to make our house-tending plan miserable, it spells doom for literally anything. Even a bush you no longer want to keep, and persistent weed variants like poison ivy pose no challenge.

The solution, in most cases, terminates unwanted weeds after a day or two. This seemingly long waiting time might put certain users off, but actually, putting it to work can be much faster than other liquid weed killers. Thanks to it being a ready-to-use product, you can skip the complex dilution step and go on with the application the moment opening the can.

But beware! Roundup products are extremely strong, to the point that they can make your whole flower beds wither. We would suggest using it on your patios, driveways, or simply a patch of soil you wish to clean. Avoid the lawn!


  • Easy to refill
  • Rain-proof
  • Come with a sprayer


  • Kill your ornamental plants

Preen 2464161 Extended Control Weed Preventer – Best For Crabgrass Prevention

Preen 2464161 Extended Control Weed Preventer

Preen 2464161 grabs our attention for how it manages to combine two most sought-after features of weed-control in one single can: Effective and long-lasting.

One handful of the granules contained can take out the existing crabgrass seeds hiding underneath your garden’s soil before they can mature into a threat to the landscape around. We all know that the pestering grass comes annually, and this product is all you need to take.

As the cap tightens itself around the top of the can is incorporated with a simple applicator system, you can easily enjoy this power without digging your fingers through the chemical grains. Just casually stroll around the area you want to apply them on, the opened can in hand, and the job will be done before you know it!

There is a lot more to love about this anti-weed product, with the top one being how it lets almost all perennial residents of your garden off the target list. The producer is even thoughtful enough to include an instruction of what vegetation it never harms in the process. They claim that the number exceeds 600 – what a good thing to hear!

But even though this is one of the best crabgrass preventers that puts an end to your crabgrass nightmare, it can only do so when they are still tiny germs underground. You have to pluck off the already emergent weeds on your own.


  • Easy to use
  • Work for several surfaces
  • Terminate all grass seeds (including crabgrass)


  • Have no use against mature weed

RM43 43-Percent Weed Preventer B00CI05VFO – Best For Barn

RM43 43-Percent Weed Preventer

Leading a life in a barn or farmhouse promises a struggle like never before when the weed-growing season arrives. But coping with that head-aching onslaught will no longer be that difficult once you have got this massive weed killer at your service.

The whole 1-gallon can might look like it can run out at any moment. But since it is a concentrated formula, and water along with dilution is required during application, you can wipe out the weed on an area of over 17000 square feet! The trick is to take the right amount and stick to the instruction, only simple as that.

RM43 has designed this formula to be powerful enough to treat a large amount of invasive weed, including crabgrass and hard-to-remove variants such as poison ivy. You can already guess this result when knowing that it contains active Glyphosate and Imazapyr, some of the most lead-killing ingredients, though.

But this product is far from perfect. Despite having the strength to destroy all vegetation in its wake, it works rather slowly, too slow to be precise. It took us two full weeks to get rid of all the weeds taking over our old family farm.


  • Strong enough to kill all plants
  • Have no dangerous effects on living being after applied
  • Work on all surfaces


  • Show effect slowly

Ortho GroundClear Vegetation Killer B083JYHD3Y – Best Fast-Acting Product

Ortho GroundClear Vegetation Killer B083JYHD3Y

Plenty of weed killers take two or three days for the target vegetation to eventually wither. But many do not have the luxury of time to be kept waiting that long. Ortho GroundClear and its mighty formula to destroy unwelcome weeds in one solid hour is all you need to put this problem to rest.

Now, do not mistake that all the crabgrass littered around your home will vanish at the drop of a hat; this is no magic. Nevertheless, you can find obvious signs of withering and discoloration after that 60 minutes have passed.

For that kind of speed, it would not even be any longer than one single day until you can scoop the remains of dead crabgrass into the trash can.

Ortho also impresses us with the way they design this product to keep grass from coming back after one year long. You can easily tell from this that the power-packed solution kills all the weeds from leaves to roots, since they can always grow back as long as a little bit of them still absorbs nutrients in your soil.

The only issue we have with this anti-weed solution is that it does not belong to the all-year-long category as advertised. It only works as fast as it is supposed to on balmy, sunny days.


  • Work on all weeds, including the tough ones
  • Rain-proof
  • Come with a sprayer


  • Slow effect when the weather turns cold

Ortho WeedClear Lawn Weed Killer B07YM583XL – Best For Lawn

Ortho WeedClear Lawn Weed Killer B07YM583XL

We understand that you might find the idea of throwing weed-terminating products on your lawn anything but wise because, technically, they are all from one vegetation family. Settle down with this versatile option from Ortho then! Only the invasive weeds are removed, your own grass stays safe.

Excluding certain variants from the kill list does not mean that the product is not strong enough. On the contrary, once spraying the liquid contained on your lawn, anything not invited, from crabgrass, dandelion, clover, to over 200 species of the weed family, will wither on its own.

Meanwhile, your lawn and flower beds will not be caught in the crossfire, as long as you follow the guidance (there is a very specific one included). The producer has also made it clear that their product does no harm to bermudagrass, buffalograss, Kentucky bluegrass, and zoysiagrass. But our test told us that there could be more, with fescue as an example.

Be that as it may, this best crabgrass killer for lawns does not stay on the weed leaves well during rainy weather, so we would suggest you carry out the application only during sunny seasons.


  • Can cover up to 5000 square feet
  • Terminate weeds to the root
  • Visible results within hours


  • No rain-proof feature

Spectracide Weed Killer Concentrate B01956RZ16 – Best For Fast Rain Proof

Spectracide Weed Killer Concentrate B01956RZ16

Rain-proof is quite a common feature found in almost all liquid herbicides. But most of the time, it needs about one hour or so to activate on its own. In areas often struck by bad weather and rain comes without as much as a warning, this obviously spells bad news for the effects.

Spectracide weed killer can be your answer in this case. After splashing some on the vegetation, all you have to give is no longer than 15 minutes for the liquid to harden, then turns impenetrable. Even underneath a severe downpour, this crabgrass killer will still evenly stick to the leaves, bit by bit taking them down.

It is also worth noting that any weed under this product’s coverage begins wilting rather quickly after a couple of hours and will shift into brown two days later. You can immediately start replanting on the soil patch once getting rid of them; no further wait required.

But despite those unmatched perks, the weeds supposed to be killed might return after one or two months.


  • Massive size for numerous applications
  • Work on plenty of vegetations
  • Work on multiple surfaces


  • Risk of weed returning

Primesource Meso 4 SC Select – Best 2-in-1 Product

Primesource Meso 4 SC Select

Primesource Meso 4 SC Select plays the role of a rather unique weed control method. Provided that you follow the instructions included properly, you will be able to use it as both a seed killer and a mature weed killer. The way we see it, this pill bottle resembling herbicide can be one of your best bets when it comes to tough weed, including crabgrass and ivy.

This is a relatively strong chemical, and so when it takes care of the weed, it kills them from leaves to roots, leaving nothing behind. Since only a moderate amount is required for each use, it is safe to say that one bottle can last you a long time.

However, despite the fact that there is always supposed to be a syringe included with the whole package for measurement purposes, some users have complained about not finding it anywhere.


  • Terminate most weeds in one application
  • Detailed guideline
  • Work quickly


  • The syringe can be missing

Scotts WeedEx Crabgrass Preventer B07KXLD8VL – Best All-Season Product

Scotts WeedEx Crabgrass Preventer B07KXLD8VL

Crabgrass killer Scotts is a special pre-emergent herbicide with quite a versatile ability. During late winter and early spring, the germination period of crabgrass, it serves to fight off the quiet invasion of the seed.

Fast forward to summer and fall, one quick application of the content inside can help you avoid pulling those coming in later months, such as foxtail, spurge, and multiple broadleaf weeds.

With what we have informed you, there is no way you can miss that the anti-weed solution performs well amid all weather states and all temperatures. It will always deliver desired results, even if constantly being exposed to scorching heat or frigid snow.

However, we cannot say that we are happy with how strong this product actually is. Sometimes, you will need more than one application to do away with seemingly common plants.


  • Work with all grass (except for dichondra and bentgrass)
  • Treat approximately 5000 feet
  • Easy to apply


  • Take more than one application

Bonide (BND7462) – KleenUp Weed Killer – Best For Large Area

Bonide (BND7462) - KleenUp Weed Killer

Trying to find a product no less effective than any of the above to rid your big home of the weed-invasion problem but believing a product meant for a barn like RM43 is over the top? KleepUp weed and grass killers will be an apt substitute!

This product comes in the form of concentrated liquid with 41% made out of glyphosate and around 84 gallons for each container. If you utilize it in the right amount stated by the producer (no more than one quarter for an application), you can cover as much as 6300 feet. Do the math and see what you can achieve with all of it!

Going beyond common broadleaf weed and crabgrass, Bonide BND7462 even lends you a hand in removing more persistent grass, making it the best crabgrass killer for Bermuda grass. The result might come much slower, about two weeks for any tougher variant, but it makes sense since all of them can endure a lot.

Unfortunately, even for weeds that other solutions kill in less than two days, this product still needs approximately one week for the effects to kick in. But when it does, it makes sure no weed remains afterward.


  • Kill all types of weeds
  • Rain-proof
  • Remove even the roots


  • Take too long for the effects to show

FMC Blindside Herbicide B008YKFTU4 – Best All-Purpose Weed Killer

FMC Blindside Herbicide B008YKFTU4

If you believe that you need a weed killer for more places than just the small patch of backyard behind your home, look nowhere else than this FMC Blindside Herbicide B008YKFTU4!

You can enjoy its merciless way of dealing with crabgrass right at your place, on any commercial lawn, on your family farm, even on your private golf course! Since the product is a mighty mixture of Sulfentrazone – 60% and Metsulfuron-methyl – 6%, both are commendable chemicals in battling invasive plants, rest assured that the results will be satisfying.

So that users can utilize it as many times as possible, the container comes in a package, including a convenient tip and a dosing chamber. Therefore, even when you only receive half an ounce, you can cover as many as 20000 feet! The advertiser says it would do for 50000, but we never managed to get that far before it runs out.

However, we want to warn you in advance that the whole bottle is quite expensive, many times more than a regular weed killer in fact.


  • Kill many types of weeds
  • Easy to mix and apply
  • Terminate to the roots


  • High-cost

What To Look For In The Best Crabgrass Killer?

The following factors are what you cannot overlook to identify the reliable grass fighter that brings your lawn back to its lush and perfect state.

What Types Should Be Your Choice?

  • Pre-emergent

All pre-emergent herbicides interfere with the germination process, giving the invasive plants no chance to poke their heads through the soil of your garden. This goes for crabgrass herbicides as well.

The use of this anti-weed product blows the worry of uninvited seeds sneaking into your best-tended lawn and makes it their home unnoticed. We all know that weeds show themselves in our own space at certain times of the year, so spray some around the house during the time. You will be able to save yourself from the hassle of getting rid of them by hands later on.

  • Post-emergent

Pre-emergent weed killers only take care of weeds hiding underneath the soil. They are useless on those fully mature, and that is why you need the second type: Post-emergent herbicides.

When some weed seeds have been hitching a ride with the wind to break into your lawn, and you do not notice that until you begin seeing green eyesores everywhere, take action with one strong dose of this grass killer. Even the toughest one will be gone before you realize it.

But keep in mind that the results come the fastest only when the weed is still in the developmental phase. The fully mature ones will take more than one application to do away with.

Should You Go For Selective Or Non-selective?

You can tell a lot about each type here simply by having a look at their name.

While non-selective grass killers destroy all vegetation in the area it is applied, the selective options only end those they are designed to kill while doing nothing to nearby non-target plants.

There is no clear answer as to which one is better out of the two since it totally depends on the user’s purposes. The best advice we can offer is to check the instructions to see if the package you are holding has any effect on crabgrass, or will take down other plants in the process. What a waste it will be when tossing into your lawn herbicides meant for other species!

What Application Method Is Most Suitable?

Crabgrass killers, and any other anti-weed products, come in the form of granule or liquid sprays. They can cover large areas as well as they do for small-scale lawns, and they also work as a solution for a certain patch of your lawn where crabgrass often shows its face.

Nevertheless, most professionals would most likely have their attention on liquid spray, despite how simple it can be to store granular herbicides.

You will understand why when knowing these granules’ major downside. The weed has to be damped enough, or else they will all drop to the ground beneath. This is not something you have to deal with when using the spray formulas, for they form a mist that blankets the leaf and hardly come off, even when it rains.

Frequently Asked Questions

Now we will address some common matters that homeowners often have in terms of removing crabgrass.

Why Should You Remove Crabgrass?

There is a reason why the plant has long been labeled as ‘invasive’. Right when it manages to set foot into your lawn, it multiplies with an unbelievable speed and makes literally everywhere its home.

If you leave it to do as it pleases, soon, your place will be overtaken by crabgrass. It even grows over your well-tended ornamental grass in an attempt to spread faster.

In short, getting rid of these unwanted invaders in time, or before their germination, can save you from the future of dealing with a sprawling green mess already too massive to cope with.

Is It Possible To Grow Crabgrass As A Lawn?

The plant certainly does not make the top of the list when it comes to which grass to grow on your lawn. Still, if you want to try it out, it is not impossible.

But tending crabgrass can take all the energy out of you since the plants never stop spreading. You pluck one patch out, and another will come to take its place. Even mowing will not stop the issue. It will still grow and grow, only in a more flatter manner.

On top of that, they do not look pleasant to the eyes at all when summer comes, and will certainly leave behind a giant mass of wilted brown when they die at the end of the year.

What Is The Best Way To Get Rid Of Crabgrass?

You can try several different methods to rid your backyards, lawns or driveways of this troublesome invasive plant. But we would recommend a combination of both pre-emergent and post-emergent weed killers strong enough to deal with this annual weed.

Keep in mind that you have to opt for the actual crabgrass killer if you plan to utilize a selective weed-control solution. Many of the regular choices that usually make broadleaf species wither may be useless against this tough one.

Should You Kill Crabgrass Before Overseeding?

It is common knowledge that crabgrass dies when the winter frost settles in. For that reason, you can overseed onto an existing patch of crabgrass, and toss some pre-emergent herbicide on the area when spring has just arrived to stop them from coming back.

Remember that you should never apply any weed killer before overseeding. Otherwise, your new ornamental plants will wilt before they even have the chance to come out of their seeds.


Whether you are planning on remodeling your garden or only want to give your driveway a better look, the best crabgrass killer will not let you down.

Growingherbsforbeginners.com have already listed down several top-notch options right here in this post. You can settle down with the overall top choice, Roundup Ready-To-Use Weed Killer, which can help you take care of all uninvited vegetation around your home. Or, you can try out the Ortho WeedClear for a more improved look for your lawn.

All these products have their own pros and cons, plus they are designed for different purposes. That is why you must weigh your options carefully before making any decision. You do not want any grievance later on, do you?
