Here’s Our Top Rated Weed Killers Reviews On The Market




Compare-N-Save Concentrate Grass and Weed Killer

View On Amazon

Glyphosate is the active component of most of the weed killers. With 41% glyphosate, therefore, Compare-N-Save Concentrate Grass and Weed Killer is one of the most effective weed killers you can get on the market. Note that ordinary weed killers contain 1-2% glyphosate.

This herbicide is highly effective on broadleaf weeds. It normally starts to work within 2-4 days of application. Compare-N-Save is a systemic weed and grass killer. It can kill a wild range of weed types. It works on the plant roots and kills them completely.

It is worth noting that Compare-N-save is not a pre-emergent herbicide. So it does not work on the seeds effectively. You know what this means? It can only kill the already grown weeds on your field, but it won’t stop new weeds from emerging there. Moreover, the concentrated solution can be very slow in action. So it is advisable to dilute the solution again and again.



Ortho GroundClear Vegetation Killer Concentrate

This is perhaps the best weed killer on the market today. Besides eradicating the weeds, it also ensures your field remains weed-free for up to one year. Ortho GroundClear Vegetation Concentrate also acts fast. It works on vegetation instantly after applying, thanks to its FastAct technology. 

Composed mainly of glyphosate, isopropylamine salt, and imazapyr, Ortho GroundClear can kill virtually all kinds of weeds. In fact, it has 5% glyphosate. This vegetation killer concentrate is ideal for clearing weeds from patios, sidewalks, driveways, and gravel paths.

So you can buy just the right amount for your garden. It is advisable to apply this herbicide when the weeds are growing actively, and on a sunny day.

    There are times when I just let these weeds grow on the lawn. When I’m very lazy to just manicure them. I just let them take over. But, when it’s time for my blooms to grow, I take them out. I’m still amaze at how preen is so great at doing its job. Even after long months of not treating my lawn, preen has always been great. I’ve found success at cleaning up my lawn from these weeds with that treatment. My blooms are so beautiful, had there been a way to share photos on your comments section, you’ll see that it’s all because of preen. I really love it!

    I have a big problem with these weeds and random grass it’s so annoying! I know they’re natural but every time I see some I get triggered and i get angry. they ruin my landscape. i might get karma from killing them, so, I would like to apologize now. But, really, that compare n save herbicide helped me become a little more relaxed because I know the weeds and these random wild grass won’t just appear out of nowhere. I was actually preparing my lawn for spring time when I first saw your article on this and just wanted to extend my thanks because it lead me to compare n save. It’s the best one that i’ve used in my years of landscaping.

  3. I completely agree that trying to eliminate weed is not an easy task. However, I would be careful with choosing weed killers. for one, they could poison the soil forever! anyway, thanks for sharing. i’m a big fan of preen. but looking to switch to the organic ones. DO you have any reviews on ORGANIC WEED KILLER??? seems like a great topic to discuss. I hope you can look into the Organic options as well.

      hello there laura, i’m jenny from california. I’ve used organic weed killers and so far they’ve worked well. There are some you can purchase from amazon if you don’t want to make your own weed killer. In case you do, I’ve discovered how well vinegar works. Sure it will smell funny and weird but it works very well. There’s a recipe i found online that i followed: 3 liters of vinegar, a cup of salt and then dish soap. If you have access to borax you can use it. Use this weed killer if it’s a sunny day because the sun adn the acid = Deadly for the weeds.
