My package instructions seem different then whay ive typically seen...it says to plant in 3 inch wide troughs and space 1 in apart every direction. They are strike peas. They get about 2 ft yall. Does this sound like a good method? If i do it this way i will end up with 2 3 inch wide rows spaced 6 inches apart in a raised bed. There were pole beans in this spot up to frost last year. Any suggestions?
