A manor kitchen garden is the one part of the grounds that pays its keep twice: once in vegetables, once in beauty. The tradition behind it is the potager — beds set out in geometric order close to the house, edged with clipped hedging or herbs, planted with crops that taste of something. You do not need four acres and a team of gardeners. You need light, honest soil, a workable plan, and the willingness to be outside in July when everything demands picking at once.

The order below is the order in which the work makes sense: site first, shape second, crops third, routine last. Get those four roughly right and a plot tucked behind a hedge will feed a household from May to November.

Start With Light, Water and Access

Most vegetables want six hours of direct sun; salads and soft herbs will manage on four. Before you sketch a single bed, watch the intended ground through a day in early summer and note where the house, wall or yew hedge throws its shadow. Morning sun dries dew and holds mildew back; a bed that stays damp until ten o'clock will disappoint tomatoes and squash. A north-facing strip beside a wall is not wasted ground — it is the place for mint, sorrel and winter salad, but it is not the place for courgettes.

Access matters as much as light. You want a route from the kitchen door you can walk in wet boots with a trug in one hand, and water within reach of a hose. Ground at the foot of a slope pools cold air on frosty nights — good for brassicas, hard on early potatoes. Then the soil: a cheap pH kit and a hole dug after rain will tell you whether the ground is acid or alkaline and whether it drains. Spread compost and let the worms finish the job. If the site was once an orchard or held old buildings, have a professional soil test for heavy metals before growing food there, especially root crops.

Three checks worth doing before you commit to a layout:

• Water test. Fill the hole you dug with water. If it empties within the hour, the ground drains fast and will want compost and mulch; if it is still full the next morning, plan raised beds.
• Shade diary. Note the hours of sun in March, June and September — the June reading flatters a site that will be gloomy by autumn.
• Wind. An exposed corner will snap tall peas and shred beans. A hedge, a hurdle fence or a double row of sweetcorn will fix it.

The Shape of a Potager

The potager's charm is order. Its geometry is what separates it from an allotment, and that geometry is doing real work: it makes the plot legible in January when everything is bare, it tells you where you are going with a wheelbarrow, and it tells you what to sow next because each square has a name. Start with a spine — the axis that runs from the kitchen door, a garden gate or the centre of the house — and lay the beds either side of it. Four squares, a cross of paths and a central feature is the classic, and it is enough.

Beds should be no wider than 1.2m (4ft) so you can reach the middle from either side without standing on the soil. Main paths need 90cm for a barrow; secondary paths will do at 45–60cm. Orient long beds north to south where you can, so rows do not shade one another, and keep the edges straight — a potager forgives many things, but not a wandering line.

Edging, Materials and Scale

Edging is what gives the plan its line. Clipped box is the old answer, though box blight makes it a gamble; lavender, santolina, thyme, chives and wall germander all clip to a low ribbon and earn their keep in the kitchen. Woven hazel, aged brick or oak boards are cheaper and quicker, and oak darkens handsomely. For soil, raised beds 25–30cm deep suit bad drainage and bad backs; ground beds suit drought, holding moisture far better than timber planters.

Put something at the crossing point: an obelisk with climbing beans, a standard bay, a dipping pool, a sundial. It anchors the eye and gives the plan a centre, which is the whole trick of the style. And keep the scale honest — six generous beds will look and work better than twenty mean ones. A small potager with wide paths and thick hedging reads as a designed space; a crowded one reads as a vegetable patch with delusions.

Choosing Heritage Crops

Heritage, or open-pollinated, varieties are the reason a kitchen garden tastes different from a supermarket. They were selected for flavour and for local conditions rather than for travelling well, and you can save their seed. That said, do not turn the plot into a museum: grow what you actually eat, and grow plenty of it.

• Climbing beans. 'Cherokee Trail of Tears', 'Cosse Violette' and 'Blauhilde' crop for months and climb, which in a small potager means three times the harvest for the same footprint.
• Tomatoes. 'Brandywine', 'Costoluto Fiorentino' and 'Aunt Ruby's German Green' for flavour, with one blight-resistant variety as insurance.
• Roots and brassicas. 'Chantenay Red Cored' carrots, 'Bull's Blood' beetroot, 'Nero di Toscana' kale and 'January King' cabbage will carry the beds through winter.
• Salad and herbs. 'Reine des Glaces' lettuce, rocket, parsley, chervil and sorrel — crops you can cut and be eating within the hour.
• Flowers for the edges. Calendula, nasturtium, borage and marigold feed pollinators, fill gaps and make the beds look intentional even in a lean month.

Grow fewer varieties, in bigger blocks, and pick them young. A potager fails more often from thin, tidy rows of far too many things than from honest gluts of a few.

Rotation, Succession and the Year's Routine

Keep three or four groups moving round the beds: legumes, brassicas, roots, and potatoes with the rest. Never grow the same family in the same bed two years running, and follow a hungry crop with a green manure of field beans or grazing rye rather than leaving bare soil. Succession sowing is the other half of the trick: sow salad, radish and spinach every fortnight from March to August and you will eat from April to the first frosts instead of for three weeks in June.

1. January–February. Order seed, prune fruit, spread compost, draw the rotation on paper.
2. March–April. Sow hardy crops under cover, plant out broad beans, prepare beds, sow the first salad.
3. May–June. Plant tomatoes, squash and beans; hoe weekly; water deeply and less often.
4. July–August. Harvest daily, feed the heavy croppers, sow winter salad and kale for the cold months.
5. September–October. Lift roots, sow green manure, plant garlic and overwintering onions.
6. November–December. Mulch, clean and sharpen tools, clip the hedges, rest.

Watering, Feeding and Keeping It Pretty

A potager has to be worth looking at from the house in February as well as in August. Mulch everything with 5cm of compost or leafmould to hold water and suppress weeds, water at the root in the evening rather than over the leaves, and feed tomatoes, squash and beans every fortnight with a comfrey or nettle brew. Keep paths mown, gravelled and edged, clip the hedging twice a year, and cut flowers to bring indoors — the garden should be looked at as much as worked in.

Finally, resist the temptation to finish it. A kitchen garden is never finished: something will bolt, a hedge will sulk, a bed will want moving. Plan it generously, plant it densely, and eat the results. That is what it is for.
