Can anyone tell me how to get rid of crabgrass? We have tried so many different things on it and we just can't seem to get rid of it. It is covering a big portion of our yard.

We use vinegar on all our weeds. We mix vinegar and a small amount of dishwashing liquid (to help it stick to the weed) and spray it on crabgrass and weeds. It's cheap and I'm also very wary of chemicals with 4 kids and pets. (04/26/2004)
How do you apply it with an sprayer, do you attach to the hose? And what quantities do you use. Great idea because I won't use chemicals either & my yard is being taken over by weeds. (04/26/2004)
If you're OK with chemicals, RoundUp is the best herbicide for weeds or any unwanted vegetation. Otherwise, vinegar or salt solution will work, but may make the soil inhospitable to anything for a while. (04/26/2004)
Are you sure it's crabgrass? If it stands straight up it isn't crabgrass; probably what is referred to as foxtail or goosegrass. Roundup or vinegar are both okay to use but will kill any grass you spray it on too. (04/26/2004)
Vicki, To spray the vinegar we use a sprayer from the hardware store. It has a large plastic container that holds a gallon or more and has a short hose and a pump to build up pressure so you can spray it from the hose. Just put the vinegar and dish washing liquid in the plastic container. Most people use the same thing for regular weed killer. (04/28/2004)
As a chemist, I wouldn't recommend adding soap to the vinegar when the intended use is as a herbicide. The acedic acid is the active agent here and soap is a base which just reduces or neutralizes the acidic strength. A mild spray will "stick" well enough. The acid will continue acting even when "dry."
I might also add that vinegar is an excellent relief for insect stings & bites as well as sunburn. (06/14/2004)

We had crabgrass last year but not as bad as this year. Our entire lawn is mostly crabgrass. Our neighbors don't have crabgrass so it is not coming from them. I think it came from our landscaping company that cuts several of his customers lawns and one or more of them have crabgrass. Exactly where he started cutting in our yard this year is exactly where the crabgrass started brand new. We are going to work hard at getting rid of it still this year but next year we may try cutting our own grass. (08/02/2005)
The best way to kill crabgrass and any weed that may grow in your yard search the web for Canadian Green Grass. This seed works wornders. It survives drought, resists lawn infections, and it kills off any weeds and squeezes out the crabgrass. We just planted new seed last year in the front lawn. And I saw some of this grass seed in a magazine so i ordered some for the back lawn to overseed. It turned out that the back lawn was better looking than the front lawn. You really need to try this, the best part being its cheaper than the ordinary grass seed. Just try it and i guarantee you wont be disappointed. (04/14/2006)
