January is the right time to give wisteria its winter pruning. Cut back the whippy stems that have grown last year to two or three buds. This will create flowering ‘spurs’ to bloom in the summer. Do take care if you have to use ladders – make sure the bottom is secure on a flat surface and don’t lean over to make it unstable. If you have a vast wisteria that has gone beserk after being ignored for many years, it may pay to get in a specialist gardener who can get it back into some semblance of order and enable you to carry on with it yourself in future years.

Be prepared for bad weather
As I write this article the weather has been so unseasonably mild that the following advice may seem ridiculous, but I still feel that we will have some really bad weather in the new year so this is just in case! If there is heavy snowfall, take a broom and knock snow off evergreens or bare tree branches where the weight can break boughs. If paths are icy sprinkle with sharp sand, which you can brush up and use to improve drainage in the garden later on. Salt is not good for the garden so avoid if possible.

Mulch fruit trees, bushes and canes with organic matter unless the soil is waterlogged or frozen. This will give them a well-needed boost for the coming season.

Vines – ornamental and grape – need to be pruned now before the rising sap makes them bleed from any cuts. Prune last year’s stems back to one or two buds.

Sow a small window box
If you have a greenhouse you can sow broad beans such as ‘Empress’ or ‘Witkiem Manita’ in pots. Lettuces can be sown into plugs in the greenhouse and transplanted outside later on if wanted, or sow ‘cut and come again’ varieties into pots or growbags in the greenhouse. This also goes for those of you lucky enough to have window sills (I don’t have any!) – you can sow a small window box inside and pick off leaves as desired. Lettuces can also be sown outside under a cold frame or cloche.

Remember to recycle your Christmas tree if you have a real one. Garden centres will quite often take them, or the local recycling centre and Cheltenham council collects trees 4ft or under left out on the first refuse day after Christmas – I should imagine the other local councils do this too.
