Yes, I read somewhere on here to plant in double rows with a post/cane at each corner & string running between the posts.... so that's what I plan to do.

Or grow them in a "grid box" 12 plants set in a square with four corner posts and joined by wire/canes. I am going to try this as it's my first time.

I grow overwintered broad beans on my plot, but if yours have been grown indoors until now they will need hardening off before going outside.

Different varieties grow to different heights.  Posts spaced along each side of the rows with wires or strings stretched between them will give them support.
