What about the area where the lawn was killed, will it grow back or do I have replant? Gondalguru what you do?

I did it intentionally (like others here) last fall. Replant and all should be well. Scott's Weed and Seed contains seeding for replanting. You can also just seed with any good grass seed you choose.

Depending on what you used, it may take some time for the...er, there's no nice way to say it...poisons to disperse enough to allow growth. If it's Round-Up, go ahead and plant. It doesn't hang around for terribly long and isn't effective except on foliar/root application anyway.

If it was Season Long Round-Up, it's going to be fall until you can plant again (anything you plant in summer is doomed to failure).

I don't get it.....
You say: "I bought one of those weed kill but not grass liquids that connect to the hose. Yes I know it is a no no..."

If you bought a product that says it only kills the weeds, and not the grass - why did it kill the grass, too? Does everyone else (besides me) know that is a "no no"? I thought you can use that product for what it says it does.... kills weeds, not grass. No....???

missmary,

I thought you can use that product for what it says it does.... kills weeds, not grass. No....???

not at all. They are formulated for a specific type of grass. You have to read the list of lawns it should be used for.

hgiljr,
Did you do this same thing last year?

First time I use this product and it was intended for my lawn, St. Augustine. Did this in more then one spot. Guess I will go the replanting route. ARRR, damn chemicals...

If you bought a product that says it only kills the weeds, and not the grass - why did it kill the grass, too? Does everyone else (besides me) know that is a "no no"?

Yes.

:-)

Not really, no...like Skoot says, it has to be for the appropriate grass. If not, you may do damage. Young lawns are susceptible to damage from chemicals moreso than older and well-established ones. If you happen to hit the lawn at a weak moment, like a drought or when it doesn't have a lot of resources (like early spring), that can hurt it.

Changing to the new lawn last year invited a lot of Poa trivialis in to play. I used Certainty to get rid of it, realizing it was going to damage surrounding grasses a bit. In a few places, there's a 1' x 1' patch dead.

That's a small price to pay to get rid of triv, but I did have to dormant seed those areas.

I killed the grass by using wilson's total wipe out on my grass for weeds by not realizing that it also kills grass as well. Now I have brown patches on my entire lawn. Any advise for my stupidity?

Read the label.

Where are you and what type of grass do you have? What product did you use? How much did you use and on what size lot?

That's funny because that's what my next door neighbor did, thinking it'd kill weeds only...

I used Ortho Weed B Gone this past weekend to great success. It killed all my weeds (within 2 days) and left the KBG just fine.

i'm looking for something to kill the grass only, not my plants, i have tons of it growing in my flower beds which are huge! they are kinda over grown from all the rain we've gotten. ~Medo

@ Inajarali_yahoo_com

I made the same mistake with my lawn as what you did in 2008. Any recommendations? Should I replant grass seed? How long should I have to wait to rake the dead grass? Thank you.

It should take a month for petroleum chemicals to dissipate. After that you can reseed by using a wire rake to scrape the dead spots.

What kind of grass?

I missed this post back in 2008, but my first questions would have been what kind of grass and where do you live? As it turns out, the OP's issue was with St Augustine. There are Scott's and other herbicide products on the market that advertise safe for St Augustine which are not even close to safe for St Augustine. The buyer is supposed to know that. The only herbicide product that is safe for St Augustine is atrazine. It seems like atrazine will kill just about all plant life except for St Augustine. But other herbicides are not safe.
