**Q: how long does it take to actually kill the plants? It says visible effects in a few hours. Overnight there was some wilting, but its been a full week.**
A: After applying Ortho GroundClear Year Long Vegetation Killer1, you should expect a complete kill can be expected in 1-2 weeks.
If the area is not uniformly treated, there may be some weeds that will grow in the treated area that will need to be spot treated.

A: For me it took a couple of weeks, but it did kill everthing. I think rain has something to do with how fast it works.

**Q: I sprayed this on weeds in my yard w/ a sprayer that connects to a hose with no dilution. None of the weeds died. What could be the problem?**
A: To get the best results from any weed control, we recommend applying Ortho GroundClear Year Long Vegetation Killer1 when the weeds are actively growing, the daytime temperatures are above 60 degrees consistently and allowing at least 24 hours before watering the treated area.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good product to have around
*by D***E on September 2, 2025*

Almost used all of this up it's very effective and does kill the weeds like it says

### ⭐⭐⭐⭐⭐ Works as advertised
*by T***Y on August 29, 2025*

it worked great to get rid of the grass growing on my gravel driveway. I do need to buy another container because our driveway is very large and I missed a few spots, but this is worth the money. And some of the thicker patches of grass it took a few days for it to really die, but it did. In the area that I sprayed the grass is not growing back.

### ⭐⭐⭐⭐ Kills above ground stuff eventually
*by H***R on June 20, 2022*

It really does work and I use it every year around trees without harming them. it kills most stuff that grows but not vines like poison ivy. In fact it doesn't do a very good job killing poison ivy at all (and it isn't designed to do that). I took a star off because unless you really saturate the plants it works really slowly. In some cases the grasses have a chance to grow around the dying stuff so the slow effect doesn't really save me from having to get the string trimmer out. I have a pole fence on 3 acres and I don't want to do all that trimming. But, of you do saturate the plants around the poles well they will die and you can avoid a lot of trimming. I'd suggest buying twice as much as you think you'll need and using it liberally. Because it doesn't really affect below ground roots, nusiance trees will grow where the grass and weeds die. Keep those down with loppers and stump sprays. Kill poison ivy with different herbacide designed for poison ivy.
