[Brassica Blaz]

hi all,next spring will be my first season to harvest the long awaited spears.what i want to know is.do i still have to let any spears "grow on" or can i now harvest the lot.?

If you harvest the lot, you'll kill the plant, it needs some growth to make its food.

Stop cutting on the longest day and let the rest grow on.
