A vegetable-garden plan for beginners: simple example and method

The ideal vegetable-garden plan is not the one with the most crops. It is the one you can still water, weed and harvest in August. For a beginner, the best protection against giving up is to plan less and plan it completely.

The method comes down to four decisions: how much to grow, where to put it, when the space is occupied and how you will reach it.

Example: a 20 m² vegetable garden

Imagine four beds measuring 1 m by 4 m, separated by paths, plus a few pots near the house.

• Bed 1: tomatoes. Three or four properly spaced, supported plants, with basil only where enough light remains.
• Bed 2: courgette and beans. At most one courgette in this width, plus a bean row that will not disappear under its leaves.
• Bed 3: roots. Carrots, beetroot and radishes in small successive sowings rather than three rows all sown on one day.
• Bed 4: salads and follow-on crops. Peas in spring, lettuces during the transition, then lamb's lettuce or spinach in late summer.
• Pots: herbs. Mint confined to its container, parsley near the path and basil in sun.

This is not a universal model. It is an example of sensible density: every crop has adult space, access and a plausible successor.

Step 1: start with meals, not seed packets

Write down ten vegetables the household genuinely eats, then reduce the list to five main crops and a few quick follow-ons. A packet of seed is not a planning unit. Two people rarely need twenty-four tomato plants, while one productive courgette may be enough.

Rank crops by value to you: flavour unavailable in shops, price, how often you eat them or the pleasure of growing them. That ranking settles arguments when space runs out — as it does in every real garden.

Step 2: draw the usable area

Measure the growing area, then remove paths before counting the available surface. A bed reached from both sides can be around 1 to 1.2 m wide; beyond that, reaching the middle without stepping on soil becomes difficult.

Place constraints first: wall shade, water point, slope, daily route, trees and fixed structures. Then put tall crops to the north, or on the side where their cast shade does least harm.

The trap is drawing young plants. A courgette in a small pot fits in one hand and may cover close to a metre across. An unpruned tomato becomes a bush. Your plan must show adult volume, not planting day.

Step 3: turn spacing into quantities

Plant spacing is not a detail added at the end. It directly turns an area into a number of plants. On a 4 m row, four tomatoes at roughly 80 cm leave margins and access; eight at 40 cm create a mass that is much harder to keep dry.

For each crop, record:

• spacing within the row;
• spacing between rows;
• adult width beyond the row;
• the number of stems kept or support used;
• approximate occupancy time.

Our guide to tomato plant spacing explains why variety and training change the number.

Step 4: add time to the drawing

A static plan describes one day. The same bed might carry peas until June, a quick salad and then lamb's lettuce from August. A succession only works if the first crop genuinely clears the space before the next crop's window.

Use the sowing and planting calendar to give each crop a start window and a likely harvest period. Leave part of the garden without an ambitious succession in year one; real dates always differ from paper dates.

Three common planning errors

Filling every gap. Paths, margins and temporarily empty areas make work possible. They are not wasted.

Confusing companionship with spatial compatibility. Two plants described as companions can demand the same light or cover one another. Geometry and timing matter more than companion-planting charts.

Designing a perfect rotation before you have a history. In year one, record what was actually grown. Crop rotation becomes useful from that record, not from an abstract four-square diagram.

The most useful free plan fits on one sheet

Squared paper is enough to start. Record dimensions, paths, five main crops, plant counts and two dates per crop. If the total does not fit, remove one crop instead of shrinking every spacing.

Marmanda then automates this work without erasing your choices. You describe the garden with its dimensions and orientation, keep the chosen crops explicit, and receive a placed, dated and quantified plan. That lets you judge the compromise instead of receiving a generic list presented as a plan.
