I have put in about 240 square feet of beds using interbay mulch techniques. This is my first try. Over half the beds are new beds I plan to use no-till. All are covered in double layer burlap. Can I / should I leave the burlap in place as on organic weed barrier when I plant and mulch over them? The tutorial in FAQ seemed a little unclear on the issue. Seems like I could / should to me. 1 layer or 2? Or should I pull the bags and dry and store for next year. I aquired the burlapbags free and all bags are from food grade certified organic shadegrown green coffeebeans. Any advice and thoughts are appreciated Thanks Pete
