Planted 20 crowns in 4x8x 15" raised bed. Filled with potting soil, wood mulch and peat moss. Year planted excellent yeld. Did not harvest. Year one, maybe 1/2 (50-60) as many shoots and planting year. Again no harvest. This year, (2) maybe 20 shoots. Nothing is competing with asparagus. I dug down 3" and there seems to be a mat of very fine roots. Did I do anything wrong and what suggestions do you have. I don't want to start over but that's the way I'm leaning.
