Review: Grass-B-Gone Works! - 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.
Review: Worked.great on Bermuda grass! - I was told over and over that the Bermuda grass taking over my bedding/bark mulch areas would be a nightmare to get rid of. This was suggested to me and it worked! It took several days and I had to repeat spray on areas that might have been missed. It killed the Bermuda grass and didn't harm my flowers or shrubs. I was quite pleased with the results.

## 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.

*by M***S on October 30, 2014*

I've had this before so will go ahead and do a quick review. It works. You are supposed to spray it when the sun is out and it will dry fairly quickly. Also, you must be patient because it takes about two weeks for the grass to completely die off. There are some plants like day lilies and any that have grass-like or lance-like leaves it will kill along with that horrid Bermuda grass so be careful about that. It did burn a little of some ornamental plant but not badly and it's worth it, Roundup is too much trouble with lots of grass and plants mixed together. I can update my review when I use it on some regular grass that has taken over a large section of my front border mixed with dianthus and other plants in the spring, will try to do B4 and after photos. Using it now, the grass will just come back from seeding. I am very leery about using chemicals because of possibly being hazardous to health but this one doesn't worry me, think I did use latex gloves just in case.
