Some of your fruit trees can be pruned this month, apples and pears for example.
Keep a check on your greenhouse to make sure that it is warm enough to protect any vegetables that you may have in there. Maybe some salad for example, being nipped with frost will do the salad leaves no good at all.
You can plant garlic out at this time of year and also this is the time to try and get any raspberry canes for planting out.
If not done already, cover any brassicas with some netting to stop the pigeons. They’re just dastardly!
