George, Jimmie picked up the pine needles with the mulching mower and yet they appeared not to be broken up in any way! Our compost is narrow but long, about 18 feet. I would spread the pine needles over everything, even if they do not generate any heat yet. They will be covered with grass and leaves very soon.
