Review: I communicated with ortho company to recommend the product that will eliminate nutsedge they informed me to get this product and I followed the steps as recommended, but unfortunately no effect no result. Moreover, they told me to ask desertcart to refund!!!. How can be that ?! The product is fully consumed based on their instructions!!!!!
Review: This Works! I have a terrible invasion of Bermuda grass in a landscaped non-grass area after removing a large tree exposing the area to direct sunlight in Southern California. Did not see any results (The "leaves" will turn brown) until about 10 days after the first application. Directions state to re-apply after 7 days and do not cut the "grass" during this period. One 24 oz bottle does not cover much of an area as you must spray directly on the "leaves". I have a approximately 200+ sqft area and one 24 oz bottle was not enough for one application. I would recommend buying 4 24's or the 40 oz container if you have the same or more than a small area like mine. Product does not seem to affect any of the other plants as well! Will be interesting to see if this very invasive grass comes back as rissoles(?sp) grow up to 1 foot underground making any mechanical removal virtually impossible in a developed area. Well, about a year later and the dreaded Bermuda grass has not come back. There is some reside of the dead grass but is fading away.

## Questions & Answers

**Q: Has anyone tried this on asparagus to kill grass?**
A: If you are asking about " asparagus fern" it's not really edible asparagus, which you don't want or need to spray.  Asparagus fern is really an obnoxious weed that spreads from rhizomes, and this grass killer does not work on it. Asparagrass fern foliage looks like the edible asparagus, but it's not the same thing.  This grass-killer is a " post-emergent", meaning , that when you spray on the tassels when the nasty invasive bermuda grass, or other (we have it here in Zone 10)  goes to seed, it is absorbed into the grass and makes it impotent, so it can't reproduce anymore. The grass dies in 1-2 weeks, and does not spread it's seed, even after the seed tassels dry out.  You or you gardener then need to pull-out the dean invasive grasses, which are obvious, after 1-2 weeks, and it has not spread it seeds everywhere if using this poison, which I target and don't over-use.

**Q: can it be sprayed on a vegetable garden?  i have grass growing between my beets, carrots etc.  will it kill my vegetables?**
A: Do NOT use in vegetable gardens. This is a pre/post emergent herbicide.

**Q: Does this come in a bigger size?**
A: I think I saw a gallon bottle somewhere in the spring.

**Q: Can I use this for grass growing through my Hosta's without hurting them?**
A: Yes you can. I've used this in my flower beds with great results. Keep in mind anything in the grasses family will be killed.

### ⭐⭐⭐⭐⭐ Review
*by S***N on 3 September 2015*

I have a quite uncontrollable grass infestation in one part of my garden and have tried to dig it out many times without success. I purchased 2 Grass-B-Gone as a last resort because I did not know what else to do save killing everything in the areas with strong weedkiller and starting all over again. I am please to say this stuff really worked. However I needed to put 4 separate applications (but there is a lot of grass) and it has taken a few weeks for it to die back but it has worked. I have just bought another one to make sure the grass does get finished off once and for all.
