Killing Lawns?
Question:I recently put some weedblok over my lawn and some bark chippings over the top of that, I thought that this would kill the grass but it hasnt and it has started growing through, is there any weed killer that anyone knows of that will kill lawns but not plants. I still want to be able to plant in it.
Thanks

Ortho also puts out a weed and grass killer. It is available at Home Depot, Sears, Lowe's- to name a few.
weed killers alone will not kill grass - they are made specifically to kill the weeds IN the grass and keep the grass alive. you need to spray something like Scott's Weed and Grass killer - whatever it is make SURE it says Weed AND grass.
put down a liner on top of the lawn this will ensure nothing comes through, go to a garden/builders merchant theres a few types available now. then you can put down your chips or bark and plant through the liner
You could use roundup. You will be able to plant in a week or so. Or if you are making flower beds, you can do a lasagna bed. Put down cardboard over the area, wet it, then put compost or composted manure on, then woodchips. This will kill the grass and make great soil for the flowers to grow in. You can plant in this immediately. I made 3 huge beds like this last year, one over 60 feet long by 15 feet wide, and it worked great.
Do a search on gardenweb.com for lasagna garden and you will find everything you need.
There are selective weedkillers that will kill weeds like dandelions but not harm grass.There are other weedkillers that will kill all plants eg, glyphosate.
There is only one I know of that will kill grass and not plants, it's called 'couch grass killer'. Ask for it at your local garden centre.
Carla---any time you use a weed killer on the grass and weeds there is always a chance that the Roundup will leach in to the real plants you don't want to kill. Weeds and grass are plants---You put wood chips down and have spent money that you did not have to spend. Wood chips is more messy. Read the back of the Roundup bottle and you will see that there is a period of time that the soil must remain dormant.Why--kill the new foilege that was just planted. After the dormant periiod plant the plants ya want. Use plastic sheets when ever you use wood chips.
How about smothering the lawn with a thick layer of newspaper or heavy cardboard? Then put your woodchips or a layer of compost or topsoil over the top of that. You can plant through the paper, which will decompose and add organic matter to your soil. No chemicals needed. I have done this many times in my garden and it works great!
Thick Black polythene or the stuff they line ponds with laid on the lawn blocks out light without the light the grass will die.
Burn it, this also will kill it and leave no greenery.
If you leave it for a week you will find a new lawn will grow through.
You must dig out the roots with a rotivator and get rid of them.
No time to lose if you do not reuse the soil for your new project keep it covered or you will have colonies of weeds.
If you use weedkiller or salt to kill grass you will have to wait a long time to grow anything else in its place.
dig out the top layer of soil (the grass and roots) then add some compost and greensand, then till it in, then you are ready to plant whatever you like.
