Any suggestions on chemical free control of this weed? It's taking over a few of my raised beds.

If it's what I think it is, it's pretty easy to just pull up. But make sure to get all the roots. At least, that's true of what is referred to as Quackgrass in this area.

OK, so what if you have a big area that has it? I thought my husband made up the name, but apparently it is true. It's kind of invasive and makes the mowing area un-even really quickly.

Thank you :), it's a real pain here, as any little piece left will re grow. I've heard that solarization is the best bet, its just hard to surrender 6 weeks of the growing season

If you are unwilling to use herbicides, solarization is about the only option you have left. Unless you have a very small infestation, pulling or digging is unlikely to succeed. It's a rhizomatous plant, the rhizomes are very difficult to completely remove, and any little bits that remain will easily generate new plants.

Thanks, Kent, good explanation! So then Mccallum, not knowing your setup, is it possible to use cut black garbage bags you could lay on the soil but not cover the desireable plants? The bags would have to be staked down somehow. I've seen farmers use a type of black plastic with cutouts for the good plants in smaller fields. Just a thought.

Edit: I'm wondering if a Tractor Supply store would have the type farmers use, if you need something larger than the bags.
