I would did a hole and bury some and use the rest as mulch. I love using natural mulch like leaves or grass. If i had woodchips I'd lay a layer of leaves and then a layer of woodchips over that! I like to imagine the moist microenvironment I create that lives under and feeds on the leaves.
Bury some? Never heard of that. Something to look into more . . .
Yeah I bury leaves sometimes. I also used to bury failed compost. And by failed i mean not enough brown material in it so it started to stink so I'd get in trouble.
