The 10 Best Dandelion Killers – Reviews 2020

1. Green Gobbler Weed & Grass Killer – Best Overall

Green Gobbler Vinegar

We open the list with a weed killer that is both natural, and organic. The Green Gobbler is vinegar-based, which means it is biodegradable and entirely safe for your pets and family. It comes in a gallon container and starts taking effect within the first 24 hours.

For your money, you get something that can be effectively used not just with dandelions, but also crabgrass, clover weed, and most other common yard pests.

Unfortunately, it does suffer from the same con that is common to most organic sprays. It isn’t strong enough to contend with a true infestation. If your lawn is extremely overgrown, this probably won’t be the option for you.

Pros
  • Fast-acting
  • Completely natural
  • Versatile
  • Good value
Cons
  • Not extremely potent

2. Spectracide Weed & Feed – Best Value

Spectracide Weed & Feed 20-0-0

Sprectracide is our best dandelion killer for the money. For a very modest fee, you get a spray bottle that both kills weeds, and fertilizes your lawn. The product features a hose port that can effortlessly hookup to most garden hoses. This feature makes it easy to spray large quantities of solution in a short amount of time.

The bottle is rated to treat lawns up to 7,500 square feet in size, making it good for the majority of homes. Unfortunately, the spray is not nearly as fast-acting as many of the other options on our list. It may be several days before you start to see any results. Of course, for the money, you may be willing to forgive the weight.

Pros
  • Very affordable
  • Fertilizes
  • Good for treating large lawns
Cons
  • Slow acting

3. Bonide Weed Beater Ultra – Premium Choice

Bonide (BND310)

Buyers with a little bit of money to spend may favor the Bonide. This 32-ounce bottle is extremely potent and versatile. One bottle is able to kill hundreds of different types of weeds without doing any harm to your grass.

It’s also pretty swift. Plants start to droop in hours and die within a week after application. It is also easy to spray and becomes waterproof within hours of application.

If you need something really tough this solution is going to be an enticing product to consider. However, it isn’t going to be right for everyone. It’s a costly bottle that budget buyers will want to keep at arm’s length.

Pros
  • Very potent
  • Highly versatile
  • Fast-acting
  • Waterproof
Cons
  • Very pricey

4. Ortho Nutsedge Killer

Ortho Nutsedge Killer

The Ortho is an affordable bottle that is able to kill dozens of different types of weeds. The solution comes ready to use, and requires no mixing of any kind, making it great for buyers that want something simple and straightforward.

It’s also pretty durable. The solution becomes waterproof within just hours of spraying. In short, the product checks most boxes all for an affordable price.

Unfortunately, though, there are limits to its effectiveness. The solution is not extremely potent, which means you may run into problems if you have a major weed problem.

Pros
  • Affordable
  • Waterproof
Cons
  • Not very potent

5. Espoma Organic Weed Preventer

Espoma Organic Weed Preventer-25 lb. CGP25

The Epsoma is a corn-based nitrogen pellet weed killer and preventer. The pellets provide nutrition to your lawn, while also eliminating problem spots. Unlike many of the other options on our list, you only need to apply this solution once or twice a year to see good results.

The bag featured here is twenty-five pounds, and able to treat a yard of approximately 1,250 square feet in size. Unfortunately, the solution won’t do you much good if you have a ton of already established weeds. While it may be able to do a little bit of killing, it is much better at prevention. For a major weed problem, you will need something else but this may still be a great product for supplementary protection.

Pros
  • Only needs to be used twice yearly
  • Good for large lawns
  • Feeds grass
Cons
  • Not great at killing weeds

6. Scotts 25006A Turf Builder

Scotts Turf Builder Weed and Feed 3

Scotts is a turf protector and builder that is able to treat 3,500 square feet. The product is specifically designed both to build up the turf of your lawn and prevent future weed infestations from occurring. Buyers that need something in way of prevention could certainly do worse than this option.

Unfortunately, it isn’t completely perfect. For one thing, this is another option that is better at preventing weeds than it is killing them. Some users have also reported having some trouble with mold after application. Whether or not these things are related is difficult to determine, but it is something worth noting all the same.

Pros
  • Good for large yards
  • Feeds lawns
  • Prevents weed
Cons

7. BioAdvanced All-in-One Lawn Weed Killer

BioAdvanced All-in-One Lawn

BioAdvanced can be effectively used on over 200 different types of weeds. The 32-ounce solution can treat over 6,000 square feet of lawn and becomes completely water-proof within an hour of application.

The product also benefits from an easy to use interface. Thanks to onboard threading it is able to easily hook up to any standard garden hose for quick application.

For buyers that need something effective on a budget, this will be a solid product to consider. However, it isn’t without its issues. Unfortunately, many users living in hotter climates report that the spray did not work very well for them.

Pros
  • Good for huge lawns
  • Works on many types of weeds
  • Waterproof within an hour
Cons
  • May not work well with hotter climates

8. Roundup Lawns1 Extended Wand

Roundup 4385010

This Roundup bottle features an extendable spray wand. It is very versatile and able to work on hundreds of different weeds. It is also very water-resistant, rain proofing just a few hours after application.

The 32-ounce bottle can work on yads several thousand square feet in size and is advertised to kill weeds at the root to ensure they don’t come back.

Buyers should note that it is one of the more expensive options on our list. It’s also not great on all types of grass. Some buyers have reported that the solution killed their grass which is obviously very problematic.

Pros
  • Powerful
  • Good for large lawns
  • Easy to apply
  • Rain proofs
Cons
  • Pricey
  • May kill lawn

9. GreenView Weed & Feed

GreenView Weed & Feed

The GreenView is a 13-pound bag that can treat 5,000 square foot lawns. This nitrogen-based product is able to both provide your lawn with nutrition, and prevent weeds in the long run. Buyers will, however, want to note that it isn’t made for killing weeds that are already there.

It’s also not very good at standing up to heavy rains. If you live in a very wet climate, this bag probably won’t do you much good at all. In certain situations, it will work adequately but many users will want to stay away.

Pros
  • Good for large lawns
  • Feeds grass
Cons
  • Not very good against rain
  • Doesn’t really kill weeds

10. Environmental Factor Green it Weed Preventer

Green it Environmental Factor RTS

The Environmental Factor is an organic product that can treat yards sized at 2,000 square feet. For people that want something that is safe for children and pets, this will be an enticing option.

Unfortunately, though, there are more cons than pros with this product. For one thing, it isn’t very potent. If you have a thick weed problem, this product won’t do very well at all. It also doesn’t stand up well to rain, or heat. For smaller problems, it may get the job done, but the average user will need something with a little bit more potency.

Pros
  • Organic
Cons
  • Not very strong
  • Not resistant to water
  • Not resistant to sun

Buyer’s Guide

You’ve seen the products, but which of them spoke to you the most? If you haven’t made up your mind yet, perhaps this guide will be of use to you. Read on for some handy buying considerations.

Natural?

You may be wondering what sort of chemical contents you want to spread across your lawn and garden. Indeed, this is one of the main considerations that go into buying any weed killer. There are pros and cons to natural, and chemical-heavy products.

Organic killers are good because they are generally non-toxic. They won’t hurt your family or any animals that happen into your yard. They also tend to be biodegradable, which is great for the environment.

However, they also aren’t usually as potent as chemical-heavy solutions. Often enough, organic weed killers are just fortified vinegar. For smaller problems, this might do the trick, but when it comes to true infestations, they might not cut the mustard.

It’s all a matter of weighing your needs and your priorities.

Volume

The volume of the container determines the overall value of your purchase. The bigger the container, the better price you usually get per ounce. Of course, this isn’t a hard and fast rule, but it is a generalization you can count on to save money.

For example, a gallon-sized container may cost more than a quart, but less than four quarts. If you anticipate a future need for the weed killer (and trust us, you will probably have that future need) it’s much more beneficial to buy a bigger container.

Dose Size

Volume aside, dose size is the second most pertinent factor when determining the value of a product. Really potent killers can accomplish a lot with a few tablespoons of solution. Meanwhile, cheaper options may require half a bottle to achieve the same results.

Unfortunately, manufacturers do not always advertise the dose size on the bottle (sometimes saving this information for the user instructions). However, when you can get this info, it is certainly to your benefit to factor it into your buying decision. The stronger the chemicals, the more bang you will ultimately get for your buck.

Price

Unfortunately, weed killers can get pretty pricey. Though the cost will vary quite substantially from product to product, expect to pay somewhere in the $20 per gallon range. While this is only a loose estimate, it will still provide you with enough information to at least give yourself a budget.

For that amount of cash, you can get something good and effective.

Water Proofing

Weed killer is naturally exposed to the elements on a constant basis. While there is nothing you can do to complete immunize it against weather, there are certainly some features that can help.

Waterproofing is one of the best ways to ensure that the chemicals you lay down will actually get the chance to do what they are supposed to. The best options can become waterproof within an hour of being sprayed.

Others may take many hours, or never achieve a waterproofed state. If you live in a really dry climate, you may be able to get away with using one of these inferior products. However, most people are going to favor something that will hold up well against rain.

Sun Proof?

The sun can also undermine the integrity of a dandelion killer. Harsh sun rays can dilute the effectiveness of weedkiller. While this is always going to be a problem no matter how you slice it, some killers are better than others at standing up to harsh UV rays.

No matter where you live, it will be a good idea to invest in something that is fortified against the rays of the sun.

Temperature Threshold

For some weed killers, hot weather is a no-no. The higher the temperature, the worse the solution will work. Usually, the threshold is somewhere around 90-100 degrees. High enough that most people will be just fine on an average day.

However, there are always exceptions. For example, there are a few bottles that max out at around 80 degrees. Naturally, these options will be effectively useless in hotter climates. Bottom line: the higher the temperature threshold, the more use you will get out of your weed killer.

Spray or Pellet?

The majority of killers are sprayed. However, you will encounter the occasional pellet weed killer. These options are generally pretty easy to apply but they come with a range of cons. For one thing, it is very easy for animals to eat the pellet, making these products problematic for pet owners.

People with built-in sprinkler systems have also reported that pellets tend to clog up their products, causing additional problems.

Hose Port

Some weed killers are able to shook up directly to your hose. This is a great feature for people that want to layout lots of spray very quickly. The hose essentially automates the process so that you don’t have to keep activating an uncomfortable trigger.

Unfortunately, this is a fairly rare feature, but it is great to get whenever possible.

Trigger

Hoseport notwithstanding, there are two other main trigger mechanisms for spray killers. Automatic pump triggers are standard. With this option, you squeeze the lever to activate the spray. The method can be a little bit tiresome, but it’s more or less fine when you get right down to it.

Then there are battery-driven products. These fire automatically once you pull the trigger, with the battery pumping the bottle continuously as long as you keep your finger on the trigger.

Bottles with battery-powered triggers tend to cost a little bit more but they are much easier to use.

Conclusion

Which of our dandelion killer reviews spoke to you the most? Hopefully, you already know which of these products will be keeping your lawn beautiful. However, if you are still on the fence, you may want to revisit a couple of the standout options on our list.

For buyers that need the best and most potent product that they can get their hands on you will probably favor our top choice, the Green Gobbler Weed & Grass Killer.

And of course, budget buyers also have their options. If your goal is to save a little bit of money on this purchase, you may want to go with the Spectracide 96262 Weed & Feed.
