This stuff works - it kills EVERYTHING

[This review was collected as part of a promotion.] This will clear the ground, as the title suggests. It is not meant to simply kill weeds, and keep grass alive. Use it only in an area that needs total ground clearance, including drainage rocks (which is where I got this for). The area of overspray into any grass area will result in dead grass.

Poor

I've followed the directions. I never sprayed mature weeds a second time. Some massive adult weeds died very well, some midgrowth weeds were not affected. Does kill grass well, I never intended to use this on the lawn where weeds were, but the regular weed killer is even less effective. Not sure how long I should wait to plant grass again. The bottle says for organic gardening, that implies the half life is very fast then.

works very well

[This review was collected as part of a promotion.] I sprayed an area that was overgrown. In a matter of days there was nothing but straw. It does a good job and only leaves the dirt underneath. It will surley kill whatever it touches so do not put it where grass is to be kept.

Kills Weeds

[This review was collected as part of a promotion.] I am very happy with Ortho GroundClear. I haven't had any issues with any weeds that have survived so far. I sprayed a little less than a week ago and everything I hit has suffered from my presence. Love it.

Worked great on weeds inside Pavers

[This review was collected as part of a promotion.] I used this product to get rid of some weeds that were growing in between our Pavers, Worked well killed the weeds, the weeds did come back, and needed to respray. It is fairly quick and easy to spray.

Excellent Results

[This review was collected as part of a promotion.] We have a tree that the birds love. They scatter the seeds all over my back wooded area, causing hundreds of new tress to grow every summer. The wife and I were tired of pulling all of these trees. Asked for this product, followed the directions and sprayed a test area. Within days, the trees were starting to shrivle and soon had died. To us, this product is well worth it's cost. I will be purchasing this product when my sample runs out.

Bye Weeds

[This review was collected as part of a promotion.] Kills the weeds pretty good. But this is a concentrated liquid so be sure to read the directions to mix with water. We have the plastic pump spray so it was easy to mix together & pump & spray our unwanted weeds. We sprayed our patio path brick way & in just a couple days the weeds were dead. It will kill your plants do be careful not to spray to close to the plants you don't want harmed.

This stuff works!

[This review was collected as part of a promotion.] I tried Ortho Ground Clear on several different areas of my property and came back about a week later to see how it did. On small areas of invasive weeds it worked remarkably well, completely destroying the weeds. On heavily weeded areas, such as the back side of a fence line, the ground clear knocked the weeds back considerably but will require one additional treatment to destroy. Probably more so because the weeds were so thick, high, and full, it was difficult to get to them to spray completely. But I am very satisfied.
