Put the newspaper over the dirt 3-4 pages thick and then covered it with mulch. The newspaper will prevent any grass and weed seeds from germinating, but unlike fabric, it will decompose after about 18 months. By that time, any grass and weed seeds that were present in the soil on planting will be dead. It’s green!
This is a wonderful example of putting in plants that will attract the bees needed - the plants like flowering marjoram (and lavender, which flower longer) will ensure that. Borage, of course, is a major bee attractor! Great addition to the productive garden. http://brookegiannetti.typepad.com/velvet_and_linen/2010/07/kitchen-garden-update2.html
