Last year I made a modified Hügelkultur bed, but not mounded. I then put a low tunnel over it for seedlings. The heat of the decomposition helped warm the low tunnel, and when the seedlings were transplanted, I took down the low tunnel and planted melons. This year I started an asparagus bed there. It seems to work great. The soil there is incredible. Like making your own potting soil.

PS I say modified because instead of being a raised bed, I dug a pit first. Then filled the bottom with wood, followed by green plant debris from my cabbages and other brassicas, followed by horse manure, then compost, then capped by 2 or 3 inches of soil to level it off, then cardboard covered with leaves for mulch.
