Bulk may be cheaper if you need large volumes and have a way to haul it. Bagged mulch is often easier to handle, especially for smaller projects. Chop with a lawnmower or shredder. Whole leaves tend to compact if wet or blow away if dry. Chopping will reduce the volume and facilitate composting.
Compost leaves over winter.
Some studies have indicated that freshly chopped leaves may inhibit the growth of certain crops. Therefore, it may be advisable to compost the leaves over winter before spreading them. Use 3 or 4 sheets together, anchored with grass clippings or other mulch material to prevent blowing away. The amount of mulch to apply will be determined by the mulch material you are using.
