Grass in garden
 

Is there something i can spray in my garden to get rid of grass but not hurt any plants in the garden?

There is, but it would kill everything else. Keep in mind, grass is actually a weed, and there are quite a few varieties of it out there. Post a picture of the culprit that you are having problems with. Easier to just go in and till with a Mantis or hand till the soil along the rows weekly, to keep them down.

If the garden is all ready growing you can use Preen.

The grass is St. Augustine. I live in the suburbs of New Orleans... I really can not till as it stands, there is already a sprinkler system in the garden... Would rather not, but if i had to i could take up the sprinkler system and put a new one down when finished...

I use all raised gardens and have yet to have any problums with weeds or grass.

I used the preen landscaping mulch, does not work really good.. What is the recommended depth for mulch any way? That might be my problem, no depth... So, you are saying use the preen in the shake bottle. How good does it work and how long does it take to work?

Mulch should be about 4". any less and it's useless.
If your using hardwood mulch that does nothing but break down and mold up making a great top soil for weeds and grass.
Preen will not kill grass your going to have to get in there and pull out all the roots. It's a pre emeragent. It stops new weeds from sprouting.

Like Joe said....you gotta get in there.

I find yard work to be very relaxing....one of those mindless activities....

The key is to get the grass out and keep it out with frequent care.....you can't clean it all out then wait 2-3 months....your letting the grass get a strong hold on your garden....it's one of those things you do weekly....

Me? There is hardly a day that goes by that I don't pull a couple of pieces of grass out...I walk around...see some blades...I yank them.

I use round-up and the wick system . No over spray, better plant coverage and takes an estimated 80-90 percent less to do a better job.

Looks like i have some work cut out for me then... Thanks for the suggestions

Wouldn't round up kill the plants as well? What is the wick system?

Roundup will kill anything it touches...sort of.

i don`t think there is any that kind of thing to spray but if you wanna get rid of it you should do one thing dig all the grassy land about i feet accept plants and put sea sand on it. by doing that you will get rid of the grass with out hurting plants.

I don't quite understand. Do i dig the grass in the plant bed then pour the sand or do i just pour the sand on the areas where there is grass.
