No digging board is used. The soil will be loosened three-quarters as deep as in the
double-dig.- Continue U-barring until the bed is done; 2 or 3 U-bar passes along the length of the
bed may be necessary depending on the bed’s width. The U-bar is about 2 feet wide
and loosens the soil 2 to 2½ feet wide. - Break up any remaining large clumps with a spading fork. Shape the bed by raking
it. Then evenly spread ½-inch layer of compost and any needed fertilizers over the
entire area and sift them in 2 to 4 inches deep with a spading fork.
Note: See this page on the proper techniques for building and using a U-bar.
