I read a good tip somewhere the other day about cutting cabbage. If you have a particularly large cabbage that you couldn't possibly eat in one go - then just cut a portion out of the cabbage whilst it is still in the ground - and cover the remaining part with tin foil on the plant till you need it. Anyone ever tried this? The other thing is that when you finally cut off the whole cabbage, if you cut a cross into the stump you should get four small cabbages forming. I have done this myself and it does work.
