rotation for overwinterers

i use johns simple 3 year rotation of spuds>brassicas>others.

for winter veg i use next years brassica bed then when the winter veg has finished i put in the summer brassicas in the same place.
for example when i put leeks where the first earlies were, winter and spring cabbage where the 2nd earlies were leaving me some room to get in the early starting summer brassicas in the new year.

hope this helps?
