There is a particular pleasure in a kitchen garden that fits the space you have, whether that is a narrow strip beside a path or a modest patch behind the shed. Raised beds make that possible, turning heavy soil or awkward corners into something generous and workable. The trick is to plan carefully, not just for what you want to eat, but for how tall it grows and when it will be ready.

Start with the Space You Already Have

You do not need a half-acre to grow a useful amount of food. A plot of three metres by two metres, given raised beds and sensible paths, can keep a household in salads, herbs and summer vegetables. The first step is to measure what you have and resist the urge to cram in too many beds. A bed of 1.2 metres wide is the practical maximum, because you need to reach the centre from either side without stepping on the soil. If a bed sits against a wall or fence, keep it to 60 centimetres wide so you can reach from the front. Length is flexible, but 2.4 metres is a comfortable size for most plots.

Plan by Height and Harvest, Not Just by Crop

In the UK, the sun tracks across the southern sky, so the northern end of your plot is where the tallest crops belong. Climbing French beans, runner beans, cordon tomatoes, and tall peas will all cast shade, so put them at the back. In front of them, place medium-height crops such as chard, kale, and courgettes. The southern edge is for the low growers: salad leaves, radishes, carrots, beetroot, and herbs. This simple arrangement means every plant gets its share of light.

Harvest time matters just as much. A small garden rewards succession sowing. Sow a short row of radishes every fortnight, and you will have a continuous supply rather than a glut. Use quick crops to fill gaps between slower ones. For example, sow rocket or baby leaf spinach between young brassicas; they will be harvested long before the brassicas need the room. After early potatoes or garlic, follow with leeks or winter salads. Think of the plot as a rotation of small, overlapping harvests rather than a single summer flush.

Gravel Paths and Sensible Dimensions

Paths are not wasted space; they are what makes a small garden workable. Gravel is the traditional choice for a cottage garden, and it earns its place. It drains quickly, suppresses weeds when laid over a membrane, and looks soft and welcoming. Allow 45 centimetres for a single-file path, but 60 to 75 centimetres is far more comfortable, especially when carrying a trug or watering can. If you use a wheelbarrow, go for 90 centimetres.

Lay about 10 centimetres of pea gravel over a weed-suppressing membrane. Timber or brick edging keeps the gravel in place and defines the beds. Do not forget a firm, level surface for your feet; gravel can be loose, so compact it well. A simple mowing strip of bricks between the path and a lawn saves endless trimming.

Compost-Rich Beds from the Start

Raised beds dry out faster than open ground, so the growing medium needs to hold moisture and nutrients. A good mix is roughly 60 per cent topsoil, 30 per cent well-rotted compost, and 10 per cent grit or sharp sand for drainage. If you are filling a new bed, buy a blended loam rather than relying on garden soil alone. Aim for a depth of 20 to 30 centimetres for most crops; carrots and parsnips need 45 centimetres to grow straight.

Each autumn, top up the beds with five centimetres of garden compost or leafmould. You do not need to dig it in. Worms and weather will work it down, and the soil structure will improve year on year. A mulch of compost also keeps weeds down and protects the soil surface from baking dry in summer. For an extra feed, use a diluted comfrey or nettle tea every few weeks during the growing season.

What to Grow in a Small Kitchen Garden

Choose crops that earn their space. Herbs are generous: rosemary, thyme, sage, parsley, and chives all thrive in raised beds and can be picked little and often. For salads, cut-and-come-again lettuce, rocket, and perpetual spinach give you months of leaves from a single sowing. Roots such as radishes and beetroot are quick and reliable, and short carrot varieties like 'Paris Market' do well in shallower beds.

• Climbing crops: runner beans, French beans, peas, and cucumbers on a frame at the northern end.
• Fruiting crops: one or two cordon tomatoes, a courgette plant, and strawberries along an edge.
• Cut-and-come-again: lettuce, rocket, mizuna, and spinach for weekly pickings.
• Edible flowers: nasturtiums, calendula, and borage, which also attract pollinators.

Keeping It Productive All Year

A small garden can give you something to harvest in every month if you plan for gaps. After your summer salads finish, sow winter lettuce, land cress, and corn salad. Leeks and kale will stand through the coldest weather. A cloche or a layer of fleece extends the season by several weeks at each end. In late autumn, clear spent crops, add compost, and sow a green manure such as field beans or grazing rye if a bed would otherwise sit empty. Come spring, you will be ready to start again, with soil that is richer and easier to work than the year before.
