So I'm just learning about permaculture and my husband and I decided to make a mandala shaped sheet mulched bed in our garden. We followed the directions in gaia's garden perfectly to make a lasagna style sheet mulch. We used around 10 inches of STRAW (not hay) which I thought was supposed to be seedless by nature (I guess I should have asked this at the nursery!). Well, for some reason, after all of our hard work, we have TONS of grass from the seeds growing all over the bed. Does anybody have any advice on what to do. I really don't want to have to start over since this was a ton of work, but I also don't want a garden bed full of grass. Is there any way I can stop the grass from growing? HELP!
Location: Cache Valley, zone 4b, Irrigated, 9" rain in badlands.

My best guess is that the "grass" is the same grain as the straw, so something like wheat, rye, barley, or oats. They are annual grasses, so I'd expect them to die easily if pulled out. There may also be lots of annual weed seeds coming along shortly.
Just go ruth stout on that stuff! Put another eight inches of mulch over the top of it. If it's a grain type grass (most likely from the straw) it should smother out pretty easily. It will all turn into great soil eventually, just pile on the mulch! It'll work itself out, don't worry.... it's just a a garden after all.
Oh and one other thing... get some stuff planted in there as soon as you can. I think Lofthouse is right on the weeds, if you don't get something in there quickly nature will provide the abundance for you. It might not be something you would like or appreciate either. Take the planting into your own hands!
I tried a lasagna garden one time......barely got enough for a 9"x13" pan
Where you planning on planting right away or letting it sit first to decompose (or did you build it last winter)? If you aren't planting right away, maybe cover it up with some wet newspaper or cardboard?
