Vegetable Garden Layout — the complete planning guide
Plan a vegetable garden layout that doubles yield: tall crops north, water-needy crops grouped, 4-year crop rotation, companion planting, and 3 sample bed plans.
Vegetable Garden Layout — the complete planning guide
A vegetable garden's yield depends on three things in roughly equal measure: the climate you grow in, the soil you grow in, and the layout you put the plants in. Climate and soil take seasons to change. Layout is the one variable you can fix in an afternoon of planning — and a thoughtful layout typically doubles or triples the output of a beginner's random first attempt. This guide is the full system: the four layout fundamentals, bed vs row formats, companion combinations that actually work, the four-year crop rotation, and three sample layouts for the most common UK and US home garden sizes.
Plan it once, plant it twice: Sketch your layout in Growli's garden planner and the app remembers it season to season, automatically rotating families next year and flagging companion conflicts before you plant. No spreadsheet needed.
The four layout fundamentals
Before you draw a single bed, internalise these four rules. Everything else is implementation detail.
1. Tall crops on the north side (Northern Hemisphere)
The sun arcs across the southern sky in the Northern Hemisphere for most of the growing season. Anything tall on the south side of your plot casts a moving shadow north across shorter crops for hours a day. Result: shaded crops grow slowly, bolt prematurely, or fail to set fruit.
Put your tallest plants — tomatoes, sweetcorn, pole beans, trellised cucumbers, sunflowers — on the north edge of the plot. Where ground space is tight, many of these tall crops can grow upward instead, which is the whole premise of a vertical vegetable garden. Step down through medium plants (peppers, aubergines, broccoli, cabbages) in the middle. Put the shortest crops (lettuce, carrots, radishes, herbs) on the south edge where nothing shades them.
This rule applies across the US, Canada, and the UK (all Northern Hemisphere). If you ever garden south of the equator, simply mirror it — tallest on the south, shortest on the north.
2. Group crops by water needs
Some vegetables want consistent moisture (lettuce, cucumbers, courgettes, celery). Others tolerate or even prefer drying out between waterings (tomatoes, peppers, herbs from Mediterranean origin). If you mix them in the same bed and water them the same way, one group is always wrong.
Either put thirsty crops in one bed and drought-tolerant ones in another, or zone a drip irrigation system to deliver different volumes to different sections. The biggest yield gains from "watering more" usually come from watering the right plants more — not watering everything more.
3. Rotate plant families year to year
Plants in the same family (tomato family, brassica family, allium family) share pests and soil-borne diseases. Plant tomatoes in the same spot three years running and you build up populations of fusarium, verticillium, and nematodes that the next tomato crop walks into. Rotation breaks the cycle.
The simplest workable system is a four-year rotation with four "groups":
| Year | Group | Examples |
|---|---|---|
| 1 | Leaf / brassica | Cabbage, broccoli, kale, lettuce, spinach |
| 2 | Fruit / Solanaceae | Tomato, pepper, aubergine, potato |
| 3 | Root | Carrot, beetroot, radish, parsnip, onion, garlic |
| 4 | Legume | Beans, peas (these fix nitrogen for next year's leafy crops) |
Move each group one bed forward each year. After four years, family 1 returns to its original bed with a clean slate.
4. Leave 18 to 24 inches between rows for access
Crops squeezed shoulder-to-shoulder look efficient on paper and fail in practice. You need room to:
- Walk between rows to harvest and weed without compacting soil.
- Get a hoe blade or a hand between plants for weeding.
- Allow airflow that prevents mildew and blight.
For raised beds you can reach in from both sides, plant in dense blocks rather than rows. For wider plots, alternate 18 to 24 inch paths with planting rows or wider beds.
Bed-by-bed vs row-by-row layouts
There are two dominant approaches to organising a vegetable garden, and the right one depends mainly on the size of your plot.
| Approach | Best for | Pros | Cons |
|---|---|---|---|
| Raised beds (3 to 4 ft wide) | Small plots, poor native soil, beginners | Easy soil control, no walking on growing area, earlier soil warm-up in spring | Higher upfront cost, smaller total area |
| Traditional rows (in-ground) | Larger plots (200+ sq ft), good native soil | Maximum area, cheap to set up, easy to mechanise | Soil compaction in pathways, slower spring warm-up |
| Square-foot grids | Tiny plots, urban gardens | Maximum yield per square foot, easy succession | Heavy planning overhead, every square needs tracking |
| Mixed (beds + rows) | Medium plots | Flexible — beds for fussy crops, rows for sprawlers | Two systems to manage |
For a first vegetable garden, two or three 4 by 8 foot raised beds is the sweet spot. You get enough area for a meaningful harvest, you can fully reach every plant without stepping on the soil, and the contained format makes rotation easy to track.
Companion planting — which combinations actually work
Companion planting promises a lot and delivers some. The combinations below have credible research evidence behind them, mostly from university extension trials. Treat anything not on this list as folklore until proven.
Combinations that work
- Tomato + basil. Basil releases volatile compounds that deter hornworms and may slightly improve tomato flavour. Plant basil 12 to 18 inches from tomato stems.
- Carrot + onion or leek. Onion family scents confuse the carrot root fly; carrot foliage similarly disrupts onion fly. Plant in alternating rows.
- Brassicas + dill / coriander. Umbelliferous flowers attract parasitic wasps that prey on cabbage worms and aphids.
- Three Sisters (corn + beans + squash). The traditional Haudenosaunee (Iroquois) interplanting practice — documented in the Northeastern US for at least 500 years pre-contact and broadly adopted across Indigenous North American agriculture. Corn provides a trellis for beans, beans fix nitrogen for the corn, squash shades the soil to retain moisture. Works well in plots over 50 square feet.
- Lettuce + tall crops. Lettuce bolts in heat. Planting it on the shaded side of tall tomatoes or pole beans extends its season into early summer.
- Marigolds throughout. French marigolds (Tagetes patula) release alpha-terthienyl and related compounds that suppress root-knot nematodes (Meloidogyne spp.) — most effective when used as a cover crop or interplanted with the cash crop, less reliable as a simple border. See the UF/IFAS extension review for the research base.
Combinations to avoid
- Tomato + brassicas. Both heavy feeders, both prone to similar fungal issues, and they shade each other awkwardly.
- Onion family + beans or peas. Allium root exudates appear to inhibit legume growth.
- Fennel near anything edible. Fennel suppresses germination and growth of most nearby plants. Grow it in a separate corner.
- Potatoes + tomatoes. Same family (Solanaceae), so they share blight and pest pressure. Keep at least one bed between them.
Catch problems early: If a companion pairing is not working — yellowing, stunting, pest pressure — open Growli, snap a photo, and the app diagnoses whether the issue is spacing, watering, or family conflict.
Crop rotation — the four-year plan in practice
Here is the rotation laid out on a four-bed garden. The example assumes Bed 1, Bed 2, Bed 3, Bed 4 — but the same logic works for 4 sections within one large bed.
| Bed | Year 1 | Year 2 | Year 3 | Year 4 |
|---|---|---|---|---|
| Bed 1 | Brassicas | Solanaceae | Roots | Legumes |
| Bed 2 | Solanaceae | Roots | Legumes | Brassicas |
| Bed 3 | Roots | Legumes | Brassicas | Solanaceae |
| Bed 4 | Legumes | Brassicas | Solanaceae | Roots |
Why this order works:
- Legumes leave nitrogen-rich soil behind for next year's leafy brassicas, which are heavy nitrogen feeders.
- Brassicas leave moderately depleted soil for the tomatoes and peppers that follow — Solanaceae actually prefer a less rich soil to avoid lush foliage at the expense of fruit.
- Solanaceae are followed by roots, which tolerate the relatively used-up soil and prefer no fresh manure (which causes carrot forking).
- Roots return to legumes, which restore nitrogen for the cycle to start again.
If you only have one or two beds, divide each bed into sections and rotate within it — the principle still holds even at small scale.
Three sample layouts
Three concrete layouts for the most common home garden sizes. Numbers and spacings are starting points — adjust for your specific varieties.
Sample 1 — 4 by 8 ft raised bed (single bed)
A first-year vegetable garden in 32 square feet. North side is at the top.
North side (tall crops):
[Tomato] [Tomato] [Tomato] [Pole bean trellis ----------]
Middle (medium crops):
[Pepper] [Pepper] [Basil] [Basil] [Marigold] [Marigold]
South side (short crops):
[Lettuce row] [Carrot row] [Radish row interplanted]
Yields, roughly: 12 to 18 kg tomatoes, 2 to 3 kg peppers, 1.5 kg beans, 1 kg salad leaves over a season. Replant the lettuce and radish rows every 3 weeks for continuous harvest.
Sample 2 — 4 by 16 ft raised bed or two 4 by 8 ft beds
Doubles the area and supports a serious vegetable household. Use a 4-bed rotation by dividing into four 4 by 4 ft sections.
| Section | Year 1 contents | Approx. yield/season |
|---|---|---|
| Section 1 (NW corner) | Brassicas: 4 cabbage, 4 broccoli, kale border | 6 to 10 kg total |
| Section 2 (NE corner) | Solanaceae: 4 tomatoes, 2 peppers, 1 aubergine | 15 to 25 kg total |
| Section 3 (SW corner) | Roots: carrots, beetroot, onions, garlic | 8 to 12 kg total |
| Section 4 (SE corner) | Legumes: dwarf French beans, peas | 4 to 6 kg total |
Path 18 inches between sections. Trellis on the north edge of section 2 for indeterminate tomatoes.
Sample 3 — 10 by 20 ft in-ground plot
A full vegetable garden capable of feeding two adults through summer and into autumn. 200 square feet, traditional rows running east to west so tall crops are on the north edge.
North row (tall): Sweetcorn block + pole beans + sunflowers
Row 2: Indeterminate tomatoes (6 plants) + basil
Row 3: Peppers (8 plants) + aubergines (3 plants)
Row 4: Bush courgettes (4) + summer squash
Row 5: Brassicas — cabbage, broccoli, kale
Row 6: Carrots, beetroot, parsnips (interplanted)
Row 7: Onions, garlic, leeks
South row (shortest): Lettuce, spinach, radish, herbs
Paths 24 inches between rows, 36 inches at the south edge as a main working aisle. Compost area outside the south edge so you can sheet mulch finished rows easily.
Common layout mistakes
- Tall crops on the wrong side. Planting tomatoes on the south side of a bed shades everything north of them. Always orient by sun direction first — adjust the rest after.
- Skipping rotation in year two. Many beginners plant a successful year-one layout in the exact same spots in year two and watch yield collapse. Rotation is non-negotiable.
- Cramming too close. A tomato plant labelled "space 24 inches apart" needs 24 inches apart. Crowded plants fight for light, water, and air and end up smaller and more diseased.
- No paths. Skipping access paths to maximise growing area means you compact soil walking across it. Compacted soil drains poorly, holds less air, and stunts roots.
- Ignoring succession planting. Once a lettuce row is harvested in June, the bed sits empty until autumn brassicas if you don't have a replacement plan. Treat finished rows as new planting opportunities.
- Treating the layout as final. Year two should always tweak year one based on what worked. Plant the same area but adjust spacing, replace varieties that under-performed, and shift the family rotation forward.

Frequently asked questions
What is the best layout for a vegetable garden?
The best layout puts tall crops (tomatoes, corn, pole beans) on the north side so they do not shade shorter crops, groups water-needy crops together for efficient irrigation, rotates plant families every year, and leaves 18 to 24 inches between rows for access and airflow. A 4 by 8 foot raised bed is the simplest format for a first vegetable garden — large enough for a meaningful harvest, small enough to reach every plant without stepping on soil.
How should I orient my vegetable garden rows?
Run rows east to west so the tallest plants on the north end do not shade shorter plants. For raised beds with a 3 to 4 foot width, the orientation matters less because you reach in from both sides, but always still place tall crops on the north edge of the bed. Avoid running rows north to south unless your plot is in deep shade from a building to the south already.
What vegetables grow well together?
Tomatoes with basil, carrots with onions or leeks, brassicas with dill, the classic Three Sisters of corn, pole beans, and squash, and any vegetable with French marigolds for nematode control. Avoid pairing tomatoes with brassicas, onion family with beans or peas, and fennel with most edibles.
What is crop rotation in a vegetable garden?
Crop rotation moves plant families to a different spot each year on a 3 or 4-year cycle to break pest and disease cycles and balance soil nutrition. The simplest 4-year version rotates leafy brassicas, then tomato-family fruit crops, then roots, then nitrogen-fixing legumes, returning to brassicas in year 5. Plants in the same family share pests and diseases, so keeping them apart in time prevents buildup.
How big should a beginner vegetable garden be?
A single 4 by 8 foot raised bed (32 square feet) is the right starting size for one or two adults. It produces enough tomatoes, herbs, salads, and a few peppers to be worth the effort, but small enough to manage in 30 minutes a week. Most beginners who go bigger in year one end up overwhelmed by weeding and watering in mid-July and abandon the plot by August.
How far apart should vegetable rows be?
Leave 18 to 24 inches between rows for most crops. Wider for sprawling crops like courgettes, pumpkins, or indeterminate tomatoes (36 inches). Narrower (12 inches) for compact crops like lettuce, carrots, or beetroot in raised beds where you reach in rather than walking between. Within a row, follow the spacing on the seed packet — those numbers reflect each plant's mature spread.
Can I plant the same vegetables in the same spot every year?
Not without yield loss and disease buildup. Plants in the same family share pests and soil-borne diseases — planting tomatoes in the same spot three years running guarantees verticillium, fusarium, or nematode pressure by year three. Rotate families on a 3 or 4-year cycle. The only common exceptions are perennial vegetables like asparagus and rhubarb, which stay in one spot for decades.
Does Growli help plan a vegetable garden layout?
Yes — sketch your beds in Growli, drag in the crops you want, and the app flags spacing problems, family conflicts, and sun orientation issues before you plant. It remembers the layout year to year and auto-suggests next year's rotation. You can also start from one of the sample 4 by 8, 4 by 16, or 10 by 20 ft templates and adjust.
