Will this stop nutgrass? I hadn't thought so, but...
North Haven Gardens has a link to a post about square foot gardening on the "growlively blog", http://growlively.typepad.com/growlively/. The author of the blog is of the opinion that the easiest way to build raised beds, with soil 8" to 10" deep, is to put newspaper and weed block fabric on top of the existing soil, or to put watered cardboard on top of the existing soil, without tilling it. Then one puts the raised be on top of that, if I understand aright.
This "easiest way to go", the author feels, won't stimulate? weed seeds, nutgrass, and bermuda grass.
But what does "easiest way to go" mean in relation to nutgrass? I would have thought it would laugh and grow up right through the newspaper and weedcloth or watered cardboard.
What is your opinion, please?
It would be nice to put aside nutgrass killing efforts and garden in a raised bed for awhile. Hah. I had thought to be killing nutgrass for at least another summer before I dared put raised beds where I want them.
