These jobs are mainly the same as October's, and should be done before the hard frosts.
Fruit
Before the soil is too hard, plant bare-rooted fruit canes and bushes.
Divide the rhubarb crowns if they have grown very large.
Remove any fruit that is still hanging on the trees - it will rot otherwise.
Put grease or grease bands (sold in the allotment shop) on the trunks to protect from winter moth from climbing up and laying its eggs.
Vegetables
As last month, you can plant onions, shallots and garlic.
if you are growing salad leaves, etc, protect them with fleece or with a cloche.
Harvest parsnips, swedes, leeks, kale, cauliflowers, celeriac (see below) and winter cabbage.
Harvest Brussels sprouts from the bottom up so the smaller sprouts have a chance to swell.
Celeriac and carrots should be in before the hard frosts.
Protect celeriac and globe artichokes with straw if frost is forecast.
General
Have a bonfire. Old crops should be cleared up and burnt as they harbour pests and diseases.
Collect fallen leaves while they are damp and put them in a plastic sack to rot. Tie the sack up, pierce it a few times with a garden fork and leave it on the soil in a shady place where it won't be disturbed. It will rot down to about a quarter of its bulk. This usually takes a year, when you can just spread this around the base of your choicest plants. They will love it.
Dig over the plot (this is terrific excercise and will put you in a good mood), or cover it and leave it to the worms.
