How do you kill johnson grass?

[glen]

I had it bad at one time- I used the following method. sprayed the entire yard with remedy and killed everything. I tilled the yard and brought in 6 yards of dillo dirt and tilled it into the soil. Bought 2 pallets of grass that was brought back by a contractor at $40 a pallet and laid it out. Watered it everyday for about a month and now have one of the better lawns in the neighborhood and it is my just my second year.

You will kill it out by mowing your yard on a regular basis.

RoundUp. When I was a kid, my job all summer was to spot spray johnson grass over thousands of acres of cotton fields - one plant at a time. I HATE johnson grass.

Don't mix it strong. If you do, it'll kill everything above the ground really fast, but won't get down into the rhyzome enough to kill the roots. It'll just come back. Mix it according to the label instructions. Mix in some liquid soap to make the spray sticky. Coat the grass with the soapy RoundUp. If it takes 10-14 days before it dies, then you did it right. Most of it will die. You have to keep spraying 2 or 3 times a year to get what didn't die last time. Do it again next year when new seed comes up. Pre-emergent helps minimize that. Do NOT let it head out and make seed. If it does, then pick the heads (gently so you don't scatter seed) and throw them in the trash. You won't get rid of it in one spraying. It takes 2 or 3 years.

with one of these but round up works too. it will take several years of constant monitoring to get rid of it no matter what you do. As the son of a farmer, I can tell you that it is the DEVIL!!

good to know someone else had to do that. for years I thought my dad was just making this crap up. oh the hours I spent digging Johnson grass and pulling sunflowers, then carrying them to the turn row. good times!!

I won't, but if you put it in my wife's flower bed, she will...

Man, I'd rather do anything than spray freakin' johnson grass and bindweed. When I was 11 or 12, Dad would put me on a 4010 John Deere with a spray tank and a hand sprayer with enough hose to reach about 12 rows wide. I'd spray everything I could reach, and then I'd roll up the hose and get on the tractor and move up 30' or so. Then I'd get off and spray everything I could reach.......

With 1/2 mile rows, I could make 3-4 rounds in a day. One field was 3/4 mile rows, and I could only make 2-3 rounds a day in that one. It takes a WHILE to get a section sprayed at that pace. 12-14 hours of that all day all summer long gets old in a hurry.

spot spray with MSMA. Start with less than the called for. it will also knock your st.augustine back.
An atrazine product can be used for grassy weeds in St. Augustine, but not great.

you must be my long lost cousin! I spent days on a 4010 as well. Nothing like shredding cotton on a cabless tractor.
