I started off with Square foot gardening with 3off 4 ft raised beds.
Manage to grow lots of different plants successfully.
Broccoli was a challenge as they crowded out the smaller plants, was a good in other ways though as it led to me getting an allotment.
However I cannot get my head around the logic of spacing in lines as opposed to square foot.
Example:
It says “Onions should be spaced 2 to 4 inches apart, with 12 to 18 inches between row”
Square foot says 16 per square foot that is 3 inches apart making 16 off.
I would be very interested in hearing the reason for leaving 12 to 18 inches between rows.
