Which end do you look through? ;)

No, not joining in here.  Being a cat in another life I dislike inclement weather so there's no way I'm concentrating  on anything that needs harvesting in the dead of winter.  I'm unconcerned that the land is fallow in winter and half the things on your list Veggie,  I wouldn't bother with either.   Every year I leave the chard in the ground in the hope it will provide summat during the winter it never does, and I never go out to pick it.  It just gets dug out late spring when I need the space.  I just have to admit I'm a fairweather gardener but all credit to those of you who are different.

Grow stuff in your GHs over winter - that's where I intend to grow more. Nice and dry and warm - the perfect place for coffee. At the mo, there's lettuce, rocket, spinach, chard, kale, spring onions, beetroot and some other green leaved things whose names I've forgotten. Next winter, I'll try to grow more roots there.

Spring cabbage,dwarf broad beans and garlic grow well in the greenhouse over winter.

I remember reading this from one of your posts several year ago....I'm nit very good with cabbage grown outside due to pigeons but I took the advice and often grow - Durham early in the greenhouse over winter. Uses the space and I use them S spring greens.
