Effective easy to use and almost odor free product!
[This review was collected as part of a promotion.] I was a bit eseptive about this product at first, but about 8 days after applying it, I started to notice that underneath my garage door that stubborn weed wasn’t growing anymore! I had literally to be removing it every 10 days, so this definitely is effective and life changing! It doesn’t have a strong smell, what I actually loved and it sprays the right amount of product, making the application pretty easy!

Great on weeds
[This review was collected as part of a promotion.] It was a little hard to get the nozzle hose out of the handle and connecting to the the bottle. But after that it was easy to use. My luck it started rain but it still work.

Not the best
[This review was collected as part of a promotion.] Let’s start with what I liked. The container was easy to hold and the spray did have good coverage. It was easy to use with one hand and hold the jug at the same time. The spray did work quickly but only turned the leaves brown. It did not kill the entire plant and they quickly came back.

Works on moss and keeps concrete weed-free!
[This review was collected as part of a promotion.] This product has become a spring and summer staple. It works great on weeds, but was particularly helpful on weeds that were sprouting in cracks in our concrete. Weeds had been a recurring problem, and it was impossible to pull them out successfully from the cracks. This product was incredibly easy to use, dried quickly, and had an even and strongly concentrated application from the nozzle. By the next day the weeds were shriveled up and browned. It even worked on some stubborn moss growing on our stone wall. Sprayed it after work and by the morning, the moss was brown and brushed off easily, as seen in the pictures!

Works fast and easy for use
[This review was collected as part of a promotion.] This weed killed was easy and worked pretty quickly on most weeds and grass around my driveway and patio area. I like the spray nozzle and that I could already see results within a day or two. The only reason I am not giving it perfect score is because a few tougher weeds needed a second application. Overall, it did a good job and made the area look much cleaner.

It definitely helps!
[This review was collected as part of a promotion.] As you can see, this stuff definitely helps to kill anything green. It works pretty quickly and makes weeds shrivel up and dry out. They are still pretty hard to pull out unless you wait a few days. Overall I do think this product has its place in gardening and landscaping for maintenance.

Works? Absolutely
[This review was collected as part of a promotion.] Works? Absolutely, you can see in the picture where it’s shown a dead patch of grass and a green on right on the side. I sprayed only part of the patch and boom, it died a few days after. The other patch unaffected (because I didn’t spray it). Easy to spray, I experienced that the weeds dried after around 3-5 days after spraying. Very worth it

Does its job well and quickly killing unwanted weeds and moss
[This review was collected as part of a promotion.] The ortho groundclear weed and grass killer is very easy to use and works well for targeting unwanted moss and weeds. The convenient handle makes it comfortable to hold while spraying, I like that the spray nozzle securely attaches right into the container for easy storage. The nozzle sprays easily and puts out a good amount of product, spraying exactly where I want to go without wasting any product.

Works quickly
[This review was collected as part of a promotion.] We found this easy to use. It seems to take more than our usual brand to kill the weeds, but still worked pretty good. It wilted them quickly and we were able to easily go back and remove the dead weeds from the walking stones.

Easy set up for weed elimination!
[This review was collected as part of a promotion.] This product was easy to set up and get going to start working on the various weeds that are growing in my yard. I started with the one in the picture and they moved onto other types that were growing in the grass. I have quite a few that are growing in between the cracks of my sidewalk. It looks like the product dried really quickly because what I’m showing you is after 30 seconds there’s only a little bit left where I sprayed a little bit too much. It doesn’t have an overly strong odor, which is great because other products usually have a very strong smell the packaging seems very durable so it’s great for storage in my garage. I look forward to all the weeds being gone soon.

Effective
[This review was collected as part of a promotion.] A great product to get rid of those pesky weeds! Easy and quick to spray the affected area. You start to see a difference in as all little as 15 min and after an hour it’s even a bigger difference. Very quick, easy and effective product.

Fast and effective
[This review was collected as part of a promotion.] This spray is great! It claims to kill moss in 15 minutes. I have plenty of that on my patio and have been looking for a solution for a couple of years besides spraying it away with a hose because it only comes back. This spray killed the moss patch so quickly, it turned completely brown with no life left in sight.

Effective Weed Killer
[This review was collected as part of a promotion.] The Ortho Groundclear Weed and Grass Killer really works! I’ve sprayed it on the weed sprouting out in the middle of my driveway and pavement, and they have all cleared away. It is convenient to carry, and the nozzle is easy to use and spray. This is great for maintaining my driveway and pavement areas weed free.

Works after a few treatments
[This review was collected as part of a promotion.] I received this product to test. It does kill weeds but you have to use it more than once to get rid of them. The nozzle and hose makes it easy to get exactly on the items you want - just don’t use it if it’s windy.

Clean
[This review was collected as part of a promotion.] Effectively killed the weeds that grown along the grouts of pavers in my patio, make the path looks clean and nice. In my opinion, just dont spray too much and too close your garden beds.

Affective weed killer.
[This review was collected as part of a promotion.] I received this Ortho GroundClear weed and grass killer for free in exchange for a review. First off, it should go without saying, that you need to be careful and use protective gear when using this product. Also, as it says on the bottle, you do not want to use it when it is about to rain because any runoff from it can affect aquatic wildlife. This product did work as advertised on weeds that are not too well established in the ground. On larger weeds it didn't work that well. On smaller ones it worked fine, you just want to make sure you are spraying where it can reach the stem and root of the plant. I had to use a few sprays per weed (except for the really small ones) and on some there was still a little green left at the top though the bottom was all brown even after a few days. The sprayer was a little difficult to attach to the container, but you only have to do that step once so it is not that much of a problem. I also liked that it had two different "off" dials: one on the sprayer nozzle itself and the other on the top of the bottle. If you want to be extra careful around children and pets, make sure that after turning the dial on the bottle, that you empty the last few sprays that are in the hoze before turning the dial on the nozzle. I did use this mainly for weeds between the cracks in the concrete but also for the ones that pop up between our sidewalk and the turf. From what I can tell, this product did not damage the turf, but it did kill the weeds. The weeds will of course come back after a few weeks or maybe sooner depending on the season and type of weed, but as long as you spray them again before they grow too big, you can keep them under control. I didn't have any moss to use this on so I can't speak on that aspect. All in all, this product worked as advertised, you just need to be careful and use caution when using it.

EFFECTIVE AND SAFE PRODUCT TO KEEP OUTDOOR CLEAN
[This review was collected as part of a promotion.] Ortho Groundclear works fantastic!! The label includes detail instructions on how to and safety tip. When it is sprayed on the area it drys fast and is clear. No residue was observed. This product helps keep your outdoor area clear of overgrown weeds. I highly recommend it.
