A hilling spade according to the present invention has a pair of moldboards or wings defining a plowing angle having a pointed forward end. Each wing has a central planar surface, a cutting edge, and a lower curved surface between the cutting edge and the central planar surface. The lower curved surface has a curvature oriented vertically inwardly relative to the plowing angle. Each wing also has an upper curved surface having a curvature oriented vertically outwardly relative to the plowing angle. When the hilling spade is used for hilling ridges along rows of plants, the lower curved surfaces are usable for lapping lower portions of the ridges for compacting the lower portions and for reducing erosion of these ridges. The upper curved surfaces are usable for pushing soil over the ridges and under the foliage of the plants on those ridges without damaging the foliage.
