If you cover your beds you can actually put a layer of leaf litter on top if you wish. You will find that worms will drag them down through the winter and you can generate a very nice tilth in the spring. Unfortunately, if you don’t keep the beds covered winter winds will probably blow everything away………….if you still have undigested leaves on the surface come spring, you can simply rake them up and put them elsewhere when you are ready to sow anew…………
