Cold dark nights and short gloomy days are de rigeur in January. But within the grey monotony, there are moments of clarity, where the winter sun shines bright. These precious days lift the spirits and encourage us all not to give up on the coming of spring.
Here's what to sow, plant and harvest in January.

What to sow and plant in the garden in January
Sow onions, broad beans and sweet peas
In terms of seed sowing, January is still a dark month, and outside is often too cold and wet. However, by the end of the month I generally find that I can’t wait any longer and start off onions, broad beans and sweet peas in modules, first in the greenhouse but then quickly moving them somewhere cool (but frost free) to grow on.
I find starting off sweet peas now easier than looking after them through all of winter, though these early module sowings usually require potting on and supporting with split canes or twigs, before planting out in spring.

Plant trees and shrubs
As January is usually one of the coldest months, I would avoid planting perennials (which I’ve found generally do better if they can get growing straight away). Instead, plant trees and shrubs. Bareroot season is in full swing and planting a hedge is a great way to add structure to the garden and provide habitat for wildlife.
Sow microgreens or grow herbs inside
Don’t let the low temperatures or the lack of a garden stop you growing. Even if it’s too cold to venture outside – indeed, even if you don’t have a space to venture out to – there’s no reason why you should be deprived of fresh greens. As long as you have a windowsill, you can take advantage of the micro-climate indoors to sow some quick-growing herbs and salads. Try parsley, coriander, peppery rockets and mustards, radishes or one of the winter salad mixes designed specifically to do well during the shorter days.
What to harvest and pick in January
After early winter pickings of kale, my attention turns to Brussels sprouts and kalette (flower sprout), both of which grow up the stem away from the ground, avoiding slug damage. To cook, I cut them in half and simply pan fry with garlic, pancetta (capers would be a good vegetarian alternative) and some chilli for warmth. Both also work wonders in soups and stews, combined with root vegetables and a little orzo pasta.
Salad is still cropping under fleece, with reliable lamb's lettuce and chicory now leading the way. In the garden I like to place forcers (a large heavy bucket will do) on to established plants of rhubarb and sea kale, encouraging tender crops for next month.
For the vase, a little imagination is required, though colourful stems of dogwoods and willow can create a winter fire. For capturing winter scent and charm, I like to cut a few sprigs of sweet box, arranged with racemes of mahonia flowers and snowdrops.
