If you still have any tomato plants you might want to think of discarding them now and trying to ripen off any of the green fruits that you are left with. If that’s not going to happen then why not think of making some sauce or chutney with them.
The ground where you have any old pea or bean plants can be cleared, any vegetation going onto your compost heap. The soil though can be turned over leaving any roots there that will put nitrogen back into the earth.
Any root vegetables that you still might have should be harvested now.
Autumn raspberry canes can be pruned back as can your blackberries.
Any empty patches should be turned over ready for your crop rotation next year.
