You can winter prune Wisteria this month or next. Shorten shoots that were pruned last summer to two or three buds from older wood.
Move Christmas flowering daffodils outdoors once the blooms have finished. Remove spent flower heads and feed regularly with a high potassium fertiliser until the foliage dies down.
Force rhubarb for a tender early crop by covering plants with a forcing jar or upturned plant pot. Ensure the drainage holes are covered to exclude all light. Cover crowns with a layer of straw.
Plan crop rotation for the coming season and then order or purchase seeds. Check through the seed box throwing away packets that are more than two years old.
Sow sweet peas indoors, individually in root trainers or 3″ pots.
When pruning apple trees avoid removing more than 20% of the crown in one winter. The more you prune, the more foliage grows at the expense of the fruit.
Winter is ideal to prune many deciduous trees. Magnolias are best summer pruned to avoid die back and decay of pruning cuts. As are flowering cherries, plums, and almonds to help avoid silver leaf.
Complete digging of bare beds at the allotment or home including raised beds. Cover ground with black polythene to warm beds for early crops.
On gooseberries and redcurrants remove dead and low lying shoots, shorten branch tips by one quarter, cutting to a suitable outward facing bud. Prune all side shoots back to one to three buds from their bases.
Remember to water planted containers positioned under eaves, balconies or against walls. These can quickly dry out even in winter.
