I don't have a bunch of girls working for me. We use a dolly with over sized tires and wheel barrows from a place in PA that makes two wheeled commercial units. Moving the mulch is just as easy. Once we get to the beds we start dumping the mulch. It's not like I'm asking my guys to run the Boston Marathon with a bag of mulch. The carry distance is very short. Carrying a 35-50 pound bag of mulch in one trip is much more efficient then going back and forth with a shovel a bunch of times to carry the same amount of mulch. I did 40 yards of bulk primary grind mulch a few weeks back for a native area. My crew and I will gladly take packaged mulch over bulk any day. Bags present less of a job site mess and allow you to easily meter how fast you are dumping the mulch. You can take a bag behind a hedge and into high density planting areas very easily.
