I used this product as directed on my half-acre lot and it worked perfectly. I grew a lot of weeds over time due to not tending to the yard as I needed. I was simply frustrated and wanted to start over, and so I did with this product. It took 2 days to see the results, and it was noticeable! The grass and weeds looked as if I took a torch to them. My entire yard was brown. I waited 2 weeks prior to aerating and reseeding, which my yard is back to being the best in the neighborhood. I give this product an A+++, and for the price, you cannot go wrong!


Compare N Save did exactly what it’s supposed to do. Killed EVERYTHING!! Patience is key, as the stuff doesn’t wither up and die within the first day or two. Even after a week I was thinking I’d have to reapply in some tough areas. But patience, grasshopper, and everything green was gone another week or so later. They should change the name of this product to Brown N Crispy!

I must say I hate this chemical with a passion, but I simply cannot pull weeds by hand in huge areas. I reluctantly and sparingly use this when I have no other option. Thank goodness I only have to use it in a pretty isolated and contained area. I wear gloves and change my clothes after spraying this. Trying to avoid growing a third arm out of my back.
Use with extreme caution!


Once the summer kicked off my yard was instantly taken over by weeds of all kinds. After weeding and picking and picking and weeding for what seemed like the first 2 weeks of warm weather I had, had it. I thought to myself, is this how is want to spend my summer. Nope.

As a weed preventer containing no poison, I think it works quite well. I have two dogs and I will not subject them to poisonous weed preventers or lawn food. I also use their springtime feed, summer feed, fall feed and their winterizer. When used properly these products seem to work for me. Nothing is going to stop creeping Charlie and other broadleaf weeds so don’t be a whiny lazy butt and just pull those hideous things. It’s the only way to control them. I have never had such awesome grass until I started using Espoma products. It took a couple of years to make a difference but it was worth the effort and the wait.

Kind Consumer

I ordered this after my lawn care folks discontinued their service. It seems to be the very same product they were using. The proof will be how my lawn looks in the spring. I am a firm believer in this pre-emergent weed control method. It has worked for me for years. It is a great way to avoid using poison on the lawn.

Customer Reports

Takes time to work but it does work. At least for my lawn in the Midwest. I must disclose that I double the recommended amount and add dish soap to help the liquid stick to the weeds. I also spray it more than once one week apart. Within days the weeds wilt and turn purple and eventually rot away. Applying it in this manner does stunt my lawn a little though. Your mileage may vary.


This works great, I pour a couple of ounces into a spray bottle and do spot spraying around the yard. It has taken care of all the weeds I have applied it too and you can see the results within hours. The best part is, NO damage to my lawn whatsoever! Plus with only using a couple of ounces per bottle this bottle should last a long time, a lot longer than constantly buying the weed-b-gone bottle at the store.

Kills everything! I use it on my fence line so I don’t have to weed eat all the time. My backyard is a half-acre and one of these jugs goes down one side of my fencing (just to give you an idea of how much you need).

I have a huge area of pavers in South Florida and if I don’t stay on top of the weeds, the pavers lift and it gets costly. I use this once a week where I spot new green weeds popping up and it keeps my work minimal and my eyes don’t hurt every time I step outside from seeing “future weed work.”

The product works great getting rid of common weeds. Just make sure it’s diluted properly. It does seem to temporarily stunt St. Augustine (as expected) and slows Bermuda but I’ve always seen recovery after.


I’ve tried all the branded junk in the home stores. I live in Florida so it’s a constant challenge. This is the only one that really works! There’s enough in this bottle to last a suburbanite for years of a nice lawn.

I was skeptical, but after properly weeding the garden, I sprinkled Preen. Sure enough, no weeds anywhere several weeks later! I left one area untreated as a comparison, and that spot is covered now with unwanted guests. Highly recommended, but be sure to completely de-weed first as directed on the package.


Serious gardeners need this size to save money. I have used Preen in my landscaping for 20 years+. Great product!

Some of the Amazon reviews on products I’ve purchased have been hyped Be S… plain and simple. This is the only product I’ve found to kill creeping Charlie and other weeds in a matter of hours! Couldn’t believe how fast it worked and didn’t kill my grass!


I had some very tough weeds in my lawn that I’ve been trying to kill for over 5 years. One is Creeping Charlie. I called Scott’s Professional Lawn Service and they would not guarantee their lawn spraying for Creeping Charlie. I mixed this product with liquid soap and vegetable oil. You can Google the mixture as farmers do this. No more Creeping Charlie after 3 sprayings 2 to 3 weeks apart.

WOW! This stuff worked so well! Easy to use. Came premixed and will cover a huge area. Enough for multiple areas actually. I have a gravel front yard and grass & weeds were starting to poke through. Also, my brick driveway had areas with the same issue. This worked so well… not quite in one hour, but the next day I noticed the grass & weeds where I sprayed looking dead, after 2 days, GONE! I’m amazed! Love the results of this product!


Every year I buy one can and that much is enough. The chemical is so strong that it is recommended to wear gloves while spraying this liquid. It kills the weeds and keeps them off for almost a year.

Steps to Control Weed Growth

Before you take any weed control program, it is essential to determine the types of weeds that are growing in your lawn. This is because each variety requires you to do a different process or method of getting rid of it.

There are two types of weed preventing products that you can find in the market today. One type is applied before the weeds grow or spread and the second one is applied when they are actively growing. Identifying the type of weed growing in your yard will make it easy for you to pick out what kind of weed killer to buy.

For example, broadleaf weeds are pretty easy to identify as they have wide blades of leaves. They don’t look like your common lawn grass and they can be removed with the use of selective weed control method. This means that you have to specifically use a certain method or product that can eliminate the growth of this type of weed in your yard.

Herbicide products for broadleaf are available in liquid and granular forms so you must know which ones can work better. Another type of weeds is the grassy ones. They are more difficult to detect as they can appear similar to the regular grass in your lawn. They are the ones that are commonly treated with herbicides.

There are also other chemicals used for killing grassy weeds. They are a bit stronger compared to the ones you can easily find in the market and may need certain precaution when using or they you might end up killing not just weeds. These are used sparingly too as you need to reseed the areas you have cleared with grass seeds.

What Kills Weeds Permanently?

The best and most effective way to kills weeds is by using herbicides. You have so many options to take and they are available in the market. There are pre-mixed herbicides to concentrated ones that you can use.

Of course, if you are looking for natural ways to kill weeds then you can always do these tricks yourself. You don’t have to use chemicals or even milder forms of herbicides to get rid of weeds.

Here are ways to on how to kill weeds naturally:

  1. Table salt – this doesn’t have to be fancy or expensive salt, just pick one of the cheapest salts that you can find and pour it on the weeds. This will prevent them from growing or spreading like crazy.
  2. Soap – soap has essential oils and this can help in breaking down the waxy or hairy surfaces of the weeds. This then makes the weed open to desiccants. What you need to do is add a few drops of liquid soap (detergent or dishwashing) to vinegar or vodka sprays and spray it on the leaves. Don’t wash it; leave the spray solution on the leaves and see what happens.
  3. Boiling water – pouring boiling water on weeds can make whacking easy. Boiling water can run off surfaces of the weeds and cools down before it reaches other plants.
  4. Vinegar – who would’ve thought that the best weed and grass killer is found in your kitchen? 5% vinegar is a desiccant thanks to its acetic acid. This will suction the life of plant leaves and is destructive to the immature roots of the growing weeds. Place the vinegar in a spray bottle and avoid spraying your other plants if you want them to stay healthy.
  5. A good amount of vodka – mix this liquor to 2 cups of water and adds a few drops of dish soap. Spray it on the weeds and let it dry out, this will kills the weeds in the long run.
  6. Good old newspapers – place newspapers on the weeds can help block the sunlight that it needs. Placing a least 10 sheets of wet newspapers can prevent the weeds from growing.
  7. Carpet samples or old shower curtains – just like newspapers, all you have to do is spread it on top of the weeds to prevent it from growing. You can also cover it with mulch to seal the deal.
  8. Corn gluten meal – this will prevent the germination of weeds. You can spread this around your plants or lawns to prevent weed growth.
