A mulching apparatus for attachment to a lawnmower includes a cutting assembly separate from the mower blades, wherein the grass clippings are finely cut and then dispersed onto the ground surface. A spreader assembly receives the mulched grass clippings from the cutting assembly and disperses the mulched grass clippings onto a ground surface. Optionally, the mulching apparatus includes a feeder assembly to facilitate supplying grass clippings to the cutting assembly.
