Answer: Grass clipping make a fine mulch. Just make sure the turf was not treated with a broadleaf weed control product as this can damage some sensitive garden plants. Also, don't apply fresh clippings too deeply or they may rot and produce a foul smell. Instead, add thin layers every few days, allowing each layer to dry before adding another.
Remember, however, that those grass clippings could be fertilzing your lawn as well, if you mow frequently and use a mulching mower.
