I'd like to create a new flower bed this spring but have lawn to contend with;I've heard that you can just place a thick layer of newspapers over tthe area you wish to plant and then place soil overtop in a layer of about 16 inches or so. Has anyone tried this? Does it work? Any other suggestions? Help- can't be digging out sod as I have a bad back so am loooking for the easiest way to get the job done. Thanks.
