An allotment year has four distinct moods, and the jobs that matter most shift with them. Leave the autumn digging until spring and you will spend March wrestling wet clay. Miss the July sowing window and you will be buying salad in September. None of it is complicated, though. What follows is a quarter-by-quarter plan you can pin inside the shed door, adapt to your own soil and site, and use year after year.
Treat it as a framework rather than a timetable. A plot in Cornwall and a plot in Aberdeen run a few weeks apart, and heavy clay always lags behind light sand. Watch the ground, not just the calendar.
Start with edges and paths. If you can see where you are walking and where you are planting, everything else feels manageable. Cut back last season’s woody debris, bin anything diseased, and compost the rest.
Dig only when the soil is ready. Pick up a handful and squeeze it; if it holds together like putty, wait a week. If it crumbles, get the fork out. Work one bed at a time and finish it, rather than turning over half the plot and leaving it to dry out in clods. On a new plot, don’t try to clear every inch — cover the parts you aren’t using with cardboard weighted with bricks or black polythene, and deal with them next quarter.
Direct sowing gets going once the soil has lost its chill: broad beans, parsnips, carrots, beetroot, radish, spinach and salad leaves. Onion sets and shallots go in early. Under cover, sow tomatoes, peppers, courgettes and squash, then harden them off properly — a week in a cold frame, or a sheltered corner with the cover removed by day.
Net your brassicas against pigeons from the day they go in, not the day you notice damage. Carrot fly and flea beetle are far easier to frustrate with fine mesh than to chase afterwards.
Watering decides your harvest. Little and often encourages shallow roots; a thorough soak twice a week is better. Water in the early morning or evening, aim at the soil rather than the leaves, and mulch around thirsty crops with grass clippings or compost to slow evaporation.
Before you reach for a hosepipe, check your site rules and any restrictions your water supplier has in place — allotment sites vary enormously, and some have no mains water at all. A couple of water butts filled from shed roofs will carry you through most dry spells.
Weed before anything sets seed. Ten minutes with a hoe on a dry, sunny morning kills more weeds than an hour of hand-pulling in the rain. Keep picking courgettes, runner beans and cucumbers, because the more you cut, the more the plants produce. Keep sowing, too: salad leaves, spinach, beetroot and turnips sown in July fill the gap in early autumn. Late summer is also the moment for overwintering crops — spring cabbage, winter salads, kale and Japanese onions.
This is the quarter that separates a good plot from a struggling one. Clear spent crops as they finish rather than leaving them to rot; anything diseased goes in the bin, not the compost heap. Dig empty beds roughly and leave the surface in large clods. Frost and rain break those clods down over winter, and you get a fine tilth in spring for almost no effort.
Spread well-rotted manure or compost on beds that will grow hungry crops such as beans, brassicas and potatoes next year. Leave the beds planned for carrots and parsnips bare — fresh manure makes the roots fork. If ground will sit empty until spring, sow a green manure such as field beans, grazing rye or phacelia to hold nutrients and suppress weeds.
Autumn planting is quietly productive: garlic, overwintering onions and broad beans all go in now, and fruit bushes establish best while the soil is still warm. Tidy strawberry beds, cut back old raspberry canes and clear fallen fruit from around trees.
When the ground is too wet or frozen to work, turn to the jobs that need a dry shed and a mug of tea. Repair raised-bed boards, replace worn path membrane, rebuild the compost bay and sharpen your tools. Check your tenancy agreement or ask the site committee before you build, burn or store anything new — rules on sheds, bonfires and water vary hugely between sites.
Prune apples, pears, currants and gooseberries while they are dormant. Leave plums, cherries and other stone fruit until summer, as winter pruning leaves them open to disease. Then plan the year ahead:
No plot follows the book exactly, and yours shouldn’t either. Soil, shelter, shade and the hours you actually have all shape what is realistic. If you are new to a half-plot, aim to cultivate well rather than widely, and cover the rest. Ask neighbouring plot holders what grows well on the site — that local knowledge beats any general guide, including this one.
Work within your limits, take breaks, and don’t lift more than you can manage; if you have an injury or a health condition, get advice from a professional before tackling heavy digging. Keep a notebook, too. Two seasons of your own notes will tell you more about your plot than any calendar.
