How to plan a vegetable garden that actually works

Most of gardening is doing things at the right time. Most of planning a garden is choosing things you don't have to undo later.

Get the spot right, pick a bed format that suits how you live, and leave yourself room to walk between things. Do those three and the rest of the season is downhill.

Here's how to think about each.

Pick the spot first, not the plants

It's tempting to start with the seed catalogue. Start with the place instead.

Walk around your garden, balcony, or whatever patch of outdoors you have, and watch it for a day. You're looking for three things:

Sun. Most vegetables want at least six hours of direct sun a day. Tomatoes, peppers, squash, and beans want eight. Leafy greens and herbs cope with four or five. If your only option is a three-hour spot, don't try to grow tomatoes there — grow lettuce, chard, parsley, and radishes instead.

Shelter. Wind dries soil and tears young leaves. A fence, hedge, wall, or even a row of taller plants on the windward side makes a real difference.

Water access. You will need to water — not every day, not forever, but often enough that walking a can from the kitchen sink will become a chore. If a tap is in hose range, that's your spot.

If nowhere has all three, take the spot with the most sun and work around the others. Sun is the one you can't fake.

Choose the right kind of bed

This is the choice that decides what your gardening actually feels like. There are three honest options.

In-ground beds are the cheapest and the biggest. You plant straight into the earth you've got. Roots can go as deep as they like — there's no bottom to hit — and the soil holds moisture far better than any raised bed or pot because it's connected to the ground underneath. They suit established gardens with reasonable soil and people who don't mind bending. They take longer to warm in spring, drain however the underlying soil drains, and depend entirely on what you've inherited underfoot.

Raised beds are a wooden, stone, or metal frame filled with compost. They warm up earlier, drain reliably, and put the soil at a height that's easier to reach. The big upside is that you control the soil entirely — you fill them with the good stuff, so even a garden with terrible native earth can grow well. The cost is real: timber, screws, and several barrowloads of compost on day one.

Containers and pots turn any balcony, doorstep, or hard surface into a garden. They're the most flexible and the most demanding — pots dry out in a single hot day, so watering becomes a daily summer job. Some crops thrive in them: tomatoes, chillies, salad leaves, herbs, strawberries. Others sulk: anything thirsty, anything that wants depth (carrots, parsnips), anything that grows enormous (squash).

A useful rule: if you have decent soil and patience, in-ground. If you have poor soil, raised. If you have a balcony, containers. Most home gardens end up with a mix of all three eventually.

What to actually fill a raised bed or a container with is a whole question of its own — the wrong mix will sabotage a whole season before you plant a thing. That's its own piece →.

Start smaller than you think

The most common mistake new gardeners make is scale. A bed sized to feed a small village in May becomes a weed jungle by July.

Aim for around 3 to 4 square metres of productive growing space in year one. That's roughly a bed 1 metre wide by 3 or 4 metres long — small enough to weed in half an hour, big enough to feel like a real garden. The 1-metre width matters: it lets you reach the middle from either side without standing on the soil. For containers, four or five large pots is plenty for a first season.

In a small space, fewer things grown well will always outperform a lot of things grown badly. You're learning. You want room to make mistakes without them compounding.

Leave room to walk

This is the bit nobody talks about in seed catalogues, and it's the reason a surprising number of people quietly give up on gardening: they can't comfortably reach their own plants.

Walkways need to be wider than you think.

40 cm minimum if you can only weed from one side. Tight but possible.

50 to 60 cm is comfortable — room for two feet, a kneeling pad, and a basket.

80 cm or more if you'll be wheeling a barrow or working from a low stool.

Cramped walkways turn weeding from a quiet half-hour into a real chore. Generosity here pays back in years of easier work.

Sketch it on paper

Spend fifteen minutes with a piece of paper before you dig anything.

Draw your bed roughly to scale. Block out where each crop will go. Mark which side faces north (so tall things — sweetcorn, climbing beans, staked tomatoes — can go there without shading shorter crops). Group plants with similar water needs. Draw your walkways in. Note which crops will follow on after the early ones come out.

If the spacing maths is the bit you'd rather skip, the Ortaia app does it for you per bed: enter the size of the bed, pick your crops, and it works out how many plants fit and how to space them. Either way — paper or app — the point is the same: spot the spacing problems before they become real ones.

This sketch will change. That's fine. The act of laying it out is what forces you to notice the problems early.

What's next

Planning gets you to the start line. Once you've sorted the spot, the beds, and the walkways, the next decision is what to actually grow in them — a question with more wrong answers than right ones.
