Johnson Grass

Kate · 2008-07-22T07:04:51+00:00

I know this is not a gardening newsgroup, but I don't know where else to go for help. Hopefully, someone can assist me.I have this pesky Johnson Grass (also known as Orchard Grass)invading my lawn. I am very fussy about my grass, and this is a small area that measures 1,250 square feet.A professional lawn service came out, and said to spray the spots with Roundup and once that grassy areas dies, to rake and apply a good quality of grass seed.I have been doing this for two weeks, and every morning I find more Orchard Grass. It is overwhelming to me.I think this problem is coming from my neighbor's yard as Johnson Grass spreads seeds/spores by the wind and birds.If I get new sod laid, I may still have this problem later on.I am seriously thinking about applying Roundup over the entire grassy area, then putting a heavy plastic over the top of the grass once it is cut short, and having decorative rock hauled in and put over the top.This way, I don't have to worry about the Johnson Grass coming back, and if it does, I can simply spray it and not have a bad looking area in my front yard as it will be all rock.Has anyone here had this problem?Do you see any reason why I can't just leave the old sod down, spray over it, cover with plastic, and apply rock?I can easily reconfigure my underground sprinkler system.How long would I need to leave the Roundup on the old grass before covering it with plastic and rocks?Many, many thanks to anyone who can help me.It is so much appreciated.Kate

I tell you one thing that I've learn spending summers on my grand parents farm Anything you do will only slow foreign element from penetrating your lawn You can't stop invasion from your neighbors Seeds are all over the place in the air, on your shoes etc. You will keep working on it for years (well, until you leave this World) Best time is early morning when everyone is still asleep It gives some sanity Nice and quite

1200 sq. is not that big just keep on pulling it piece by piece you will get sucked into it It's like having cup of java every morning And try not to piss your neighbors off I remember as it was yesterday when my grandpa dump 10lb bag of mint seeds all over his neighbor's yard I think poor guy try to clean his lawn for last 20 years

Johnson grass and orchard grass are _totally_ different things.

Unless you can get the neighbor to go along and treat/control the source at the same time your rowing upstream, however, whatever you have.
