As we approach the shortest day, prepare for the new growing season: clear any remaining debris from vegetable plots, making sure not to compost any diseased material. Then dig them over and incorporate soil improvers, providing the soil is not frosted or too wet.
Spend the worst of the weather in the warm, with catalogues or on the internet, making sure you have the seeds you need.
Avoid walking on the lawn if it is covered in frost – this can damage the grass, leaving brown footprints.
Apples, pears and soft fruit bushes can now be pruned. Make sure secateurs are sharp and disinfect blades between trees by wiping with methylated spirits (surgical spirit).
Stop pruning if it falls to 4oC, to avoid damaging cells swollen by the cold.
Leave the pruning of restricted forms (cordons, fans etc.) until summer.
Grey mould (Botrytis cinerea) can be a problem with winter-flowering plants in the home and greenhouse – cyclamen are particularly prone, but dead-heading regularly can keep it at bay.
Reduce watering and feeding of houseplants as the days shorten. Check they have the light they need to carry on over the winter; they can easily be forgotten in a back room that receives little natural light, or where the curtains are left closed. They are best moved to sunny window sill until March.
In greenhouses and conservatories, open vents for an hour or two on milder days, as ventilation will reduce the risk of fungal infections.
Water plants sparingly and maintain as dry an atmosphere as possible.
Remove any yellowing leaves from overwintering plants.
Thinking of planting fruit trees?
It’s important to choose varieties that will pollinate each other, so that they can give a good crop.

We rarely see much snow, but just in case:
Snow can splay or break branches of conifers and light-limbed trees & shrubs, so brush off excess snow before it builds up.
Protect outside taps from frost damage: close the tap on the supply pipe inside the house, then open the outside tap to give the water left inside space to expand if it freezes.
If the outside tap cannot be isolated from inside, make sure it is well insulated to stop it freezing and bursting the pipe or joints.
