I'm contemplating using it on the poison ivy that won't go away. I've hand pulled for the last two years, but must not be getting all the roots.

That said, it's not in my vegetable garden - just read your other thread. I would go the cardboard/ mulch route with a bit of hand pulling for any strays.

I googled it, and apparently the cardboard/mulch won't work on the quackgrass. I'm still going to use the cardboard/mulch, but for all the quack in the paths, remaining after the cardboard treatment, its going to be death by Round Up.

it wont be that easy.. you may have to reapply it a few times before it gets the idea ...

did i mention tilling your walkways every few weeks ...

btw.. why wont the tilled chunks of grass... pull out??

ken

They will pull out Ken --- but do you have any idea how time consuming it is to get it ALL out, all 2100 sq ft of it!?! Any tiny diddly-do piece of quackgrass root will sprout, and tilling chops it all up into teeny tiny pieces - all of which are going to sprout. Sod is one thing, quackgrass is entirely another....

I was going to suggest it...definitely the easier solution than fannying about with cardboard. The worst thing is that you will probably have to wait till the grass has made a fair bit of growth - you need the maximum leaf area for the glyphosate to continue down to the roots without being hopelessly diluted. Even so, I am not inclined to beat myself up - my problem is the equally vile couch grass...which invades my beds from both neighbours on either side of me. I spray an unapologetic cordon sanitaire around it every bloody spring...and whack it again in autumn.

Ok, my new favorite saying is fannying about. I'm going to have to think of a way to slip this into conversation :0)

Put on a hat and dark sunglasses. Don a wig if necessary. Use the extended use of RoundUp. No amount of cardboard and mulch is going to take out that quackgrass. Balance logic with the need. Be careful and wash your hands afterwards.

Be sure to use only the glyphosate, not the extended, since you want to plant your veggies there. Many of the current versions of RU have a secondary herbicide that kills things instantly or has season long effect, and the "extended" means that it can stay in your soil for the rest of the season and may interfere with the veggie growth.

^^ I've got the big hat and sunglasses! I got down cardboard and woodchips in a 30 x 4 section yesterday - it actually was easy and went pretty fast. I just wish mulch weren't so expensive! I'm debating whether to do the cardboard thing in one more area (between squash rows) or just lay down stray and use the RoundUp on whatever comes up; it has to do with the cost of the mulch rather than anything else. This is our first year in this house, so I don't have any leaves stockpiled to use for mulch, I have to buy it. Or, I could put straw over the cardboard -- but I'd be worried about it blowing away (the straw works great in the veggie garden overall, though - and sure is a heck of lot less expensive, considering how far a bale of straw goes).

Oh boy! Good thing you checked!:) I would go with using straw.
