That's great you've got your smallholding now
You can still put in things like winter brassicas, if you buy young plants - too late for seed. That would include spring cabbage, winter sprouting broccoli
and my favourite, kale of various kinds.
In the salad bed you can sow mizuna which is winter hardy, and lambs lettuce which is tiny but easy to grow (you eat the whole little plant).
If you sow them right now, and give some cloche protection - and slug protection - you might just get a crop of quick growing dwarf french beans (choose an 'early' variety - it just means they mature more quickly). I wouldn't try it up here in Scotland but I have a son living in Hampshire for whom this will work.
You can also plant overwintering onions (Japanese onions) which are ready in late spring, long before maincrop onions.
Garlic goes in in about November to give larger heads than spring sown crops.
Under cover you can plant a few first early potato tubers to get a few spuds for Christmas.
From November on is the time to plant fruit trees, canes and bushes, rhubarb, strawberries and so on.
Once you've run out of things to plant you can prepare the area for spring sowing
