I plant them like corn ( 4 inches apart) and when they come up I thin them out as I want to. Seeds are so cheap if you buy them from the right companies that you can do this sort of thing. I do plant them about an inch deep and I make sure that I have 3-6 feet of open space and each side of that row. You may not think you need that much space, but then one day you go out there and they are six feet out in all directions.
