Hello folks, I’m new to no-dig and have come across it in my quest to help make a community orchard easier to maintain. The orchard has an established asparagus bed which has been overgrown by bindweed in the last couple of months. I’ve got the No Dig Organic Home & Garden book which talks about creating an asparagus bed by mulching over weeds and planting asparagus through the mulch. So can I mulch around the asparagus in our existing beds, say with cardboard and polythene fabric, and get the same result in terms of killing off the weeds? Will it work the same way?
