Planning and Building Your Vegetable Plot

Choosing the Site

The three most important factors in siting a kitchen garden are: sunlight, shelter, and drainage.

Sunlight: Most vegetables need at least six hours of direct sun per day. A south or south-west facing aspect is ideal. Avoid the shadow of buildings, walls, or trees — even partial shade dramatically reduces yields of fruiting crops like tomatoes, squash, and beans.

Shelter: A sheltered site is more productive than an exposed one. Cold winds reduce growth, damage plants physically, and increase water loss. A hedge (which filters wind rather than creating turbulence) is better than a solid fence as a windbreak. Ensure the shelter does not create shade.

Drainage: Few crops will thrive in waterlogged soil. Choose a site where water does not stand after heavy rain. If your site is heavy clay or has poor drainage, raised beds are the answer.

Sizing Realistically

New gardeners consistently overestimate how much ground they can manage. A 4m × 4m plot (16 square metres) is a good starting point for a family, producing a meaningful yield of salad, root vegetables, and some main crops without becoming overwhelming. Expand only when you have the first area under control.

The Permanent Framework

Design for the long term with permanent features:

Paths wide enough to kneel and work from (minimum 45cm)
Beds no wider than 1.2m (you must reach the centre from both sides)
A compost area — two or three bays, large enough to handle all garden waste
A water source — a water butt or tap nearby saves enormous effort

Preparing the Ground

For a new site on grass or weeds:

In autumn, lay thick cardboard over the entire area. Overlap edges generously.
Cover with at least 15cm of compost, topsoil, or a mix.
Leave over winter — by spring, the cardboard has killed the grass and begun to rot.
Mark out beds and paths. Plant directly into the compost layer.

This no-dig approach is far less labour-intensive than digging and produces excellent results in the first year.

The Four-Year Plan

From the start, design your beds in groups of four for crop rotation. Number them, keep records, and follow the rotation faithfully. The discipline of record-keeping — even a simple notebook — transforms the vegetable garden from reactive management to intentional cultivation.
