You can still sow broad beans, best variety to sow now is Aquadulce Claudia; pea varieties like Feltham First or a newer variety Meteor.
You can sow Mizuna for some winter salad leaves if you are in the south of the UK or have a poly tunnel or greenhouse.
Winter lettuce varieties like Winter Marvel or Reine de Glace and spring onions can be sown in the greenhouse or a poly tunnel.
November is also the best time to plant garlic.
Now is a good time to start making new beds and borders if the ground is not too soggy.
Dig over existing beds or ground especially if you are on clay soil as the frost (if we get any) will help break it up.
Plant bare rooted deciduous trees, shrubs and hedging plants. If the ground is frozen when they arrive cover the roots with compost and sacking or heel them in.
Mulch around trees and bushes.
If you are growing brassicas, you might like to cover them with netting to keep the birds from eating them, pigeons will quickly strip them. (Although mine are still covered with caterpillars!)
Also it is worth making sure tall brassicas are really well firmed into the ground to stop them rocking about in the wind.
Remove and compost any yellowing brassica leaves.
Tidy up your garden generally, leaves are best put in a seperate heap to decompose into leaf mould which takes a couple of years or tie them into a black bin bag with a couple of holes in it. Try and leave a small corner with a log and sticks plus a few leaves for benificial insects to overwinter in.
Wash and scrub out plant pots so they are clean and ready for use next year.
