What are you using to build the bed?Just filled a 16' x 8' raised bed with dirt. It is destined to be my new Blueberry patch. I figure it should hold 10 bushes. 2 rows of 5 with an aisle in between for picking.
Also built up and then filled an 8' x 12' raised bed for some veggies. I've been building a raised bed garden for my wife. Another couple beds to go.
Very sore now. Even though the heavy lifting was done by a front end loader.
