Sounds like your Dad planted his asparagus crowns the right way. My problem is I only have a 4'x12' area to work with for all 35 crowns. With three rows planted in that small area, they would only be about a foot apart in all directions. I could run a long straight single row right down the border line between my property and the neighbors but the only problem with that is when the asparagus goes into ferns. They would be hanging in the neighbors yard and cause him problems while trying to mow his lawn. This is why I would like to put 3 rows into a single wide bed to keep the ferns away from the neighbors property. If I did it this way, the bed would be a good five foot away from the property line. The bed would be at the north end of my yard and would run in a east to west direction. It would be rectangle in shape.
