I have several raised beds, all of which are 4 x 4 foot.

Is it better to space the tomatoes 2 feet apart, which allows the plants to be 1 foot from the end of the bed (my current setup).

or.

is it better to plant the tomatoes 6" from the edge of the beds and have 3 foot spacing. I was thinking this would not be as preferred in this condition as the plants would be too close to th walls of the bed.

Thanks in advance.
