MY leaves all go into the compost piles. I build 2-3 large ones every year that my husband turns with the frontend loader on the tractor. A friend keeps his mule on my property and the mule always poops in the same spots in the field-leaving me big piles to load up for my compost. I also have made deals with several cemeteries. I remove all the dead plant material after memorial day which includes potted plants. The dead flowers and greenery go on the compost pile and the potting soil from the plants gets reused in the garden. This way the cemeteries don't have to pay to have it all hauled off in dumpsters and it doesn't go to the land fill.
