Hi, I’m new to raised bed gardening and haven’t read about the square foot gardening method. The seed packets for these peas say 2″ apart and 18″ between rows, but in the picture your rows are pretty close. Is that more 18″ more for conventional farming? My bed is 5ftx3ft and I just planted one single row (5ft) of peas on the back side of my bed. I plan to add more every 2 weeks or so to have fresh plants in the ground. Now I’m seeing the method you’re using and I’m curious if really needed to take up so much space.
