Vegetable Growing Guides — Global
On this page
Vegetable growing guides that work in any climate. These describe what each crop needs rather than the date to plant it — soil temperature, frost tolerance and day length behave the same way everywhere. Read the conditions, measure your soil, and the same guidance holds in either hemisphere and at any latitude.
Work from temperature class, not from a date
| Temperature class | What it means | How to time it |
|---|---|---|
| Hardy cool-season | Survives frost; germinates in soil from about 4-5°C (40°F). Kale, spinach, garlic, broad beans. | Sow as soon as soil is workable and above its germination minimum. Frost improves flavour in several of these. |
| Half-hardy cool-season | Tolerates light frost; prefers soil 7-15°C (45-60°F). Lettuce, carrot, beet, radish, pea, most brassicas. | Sow from a few weeks before your last frost. Bolts once sustained heat arrives, so the second sowing window after peak heat is often the better one. |
| Tender warm-season | Killed by frost; needs soil above 15-16°C (60°F). Tomato, pepper, eggplant, bean, cucumber, squash, sweet corn. | Transplant only after your last frost has passed AND night temperatures hold above about 10-13°C (50-55°F). Planting into cold soil stunts these permanently. |
| Heat-loving | Needs soil above 18-21°C (65-70°F) and long warmth. Sweet potato, okra, melon, some peppers. | Wait for settled warmth. These gain nothing from an early start and are damaged by cold soil. |
Choose crops that fit the climate you have
Once you know a crop’s temperature class, the next question is whether your climate offers that class a window at all. Most disappointment in gardening outside the temperate zones comes from trying to grow a crop in a season that never arrives.
| Your climate | What it gives you | What to choose, and what to stop trying |
|---|---|---|
|
Cool temperate short warm season, real frost |
A clear cool-season window at each end and a short warm middle. | Everything hardy and half-hardy does well. Tender crops need starting under cover. Heat-loving crops need protection or should be left alone. |
|
Warm temperate / Mediterranean hot dry summer, mild wet winter |
Two cool-season windows and one long warm one. | Grow cool-season crops through autumn, winter and early spring — not in midsummer, when they bolt. Tender and heat-loving crops own the summer. |
|
Subtropical hot humid summer, mild winter |
A long warm season and a short, precious cool one. | Winter is your best cool-season window and it is brief — sow it deliberately rather than by habit. Humidity, not cold, is the main disease pressure. |
|
Wet-and-dry tropics no cold season, monsoon |
Two seasons divided by rain, not temperature. | Treat the start of the dry season the way a temperate gardener treats spring. Sustained heavy rain is the limit, not frost. Hardy cool-season crops mostly will not head or bulb here. |
|
Equatorial warm and wet year-round |
Continuous growing, and almost no day-length change. | You can sow most warm-season crops at any time. Day-length-triggered crops — bulbing onions, some spinach and lettuce — behave unpredictably; use day-neutral cultivars. |
|
High altitude warm days, cold nights, strong sun |
A long season by the calendar and a short one by night temperature. | Judge by night temperature, not by afternoons. Cool-season crops thrive. Tender crops need the nights checked before anything is planted out. |
If your climate is not on this list, the classification that matters is still just three questions: does frost occur, does the year divide by temperature or by rainfall, and does day length change enough to trigger bolting? Answer those three and every guide below becomes usable.
Growing guides (22 crops)
New to growing? Start here
These forgive a late sowing, patchy watering or a first attempt at spacing. Get three or four of these right before you commit a whole bed to anything trickier.
- Radishes — Ready in under a month in almost any climate, so a failed sowing costs nothing.
- Lettuce — Fast and forgiving in cool conditions — the only real skill anywhere is timing it around sustained heat.
- Spinach — Handles cold well; the skill is sowing it into the cool window before daylight and heat push it to bolt.
- Peas — A genuinely low-effort cool-season crop almost anywhere frost or mild winters allow it.
- Beets — Roots and greens from one sowing, slow enough to forgive an inconsistent start in any climate.
- Bush beans — No staking needed — wait for warm soil, then it largely looks after itself.
- Green onions — Sow direct, cut as you need them, sow again — about as low-commitment as a crop gets.
- Fava beans — Hardy enough to overwinter in mild areas, and they leave the soil better than they found it.
The reliable core of the plot
Once you've got a season behind you, most of a productive plot is built from crops in this group — well understood, forgiving of an average year, and worth the space every time.
- Tomatoes — The crop most gardens are built around, in any climate. Needs consistent moisture and the right soil-temperature transplant — both are worth learning.
- Potatoes — Plant, hill, harvest — one of the highest-yield uses of bed space for the effort, wherever you garden.
- Onions — Slow and unglamorous, but reliable once sowing-to-transplant timing is sorted — day-length-sensitive varieties matter more near the equator.
- Carrots — Wants loose, stone-free soil more than it wants skill — true everywhere it's grown.
- Cabbage — A dependable staple almost anywhere; rotate it properly wherever clubroot risk exists.
- Zucchini — One or two plants outproduce most households in any warm-season climate.
- Cucumbers — Wants warmth and steady moisture; give it both and it's one of the most productive crops per square foot.
- Leeks — Slow but dependable, and they stand in the ground through winter until you want them.
- Shallots — Planted as sets like onions, but each one splits into a cluster — low effort once they're in.
Crops that ask more of you
Get the timing and conditions right and these are the most satisfying things you'll grow. Get them wrong and they sulk, stall or fail outright — there's very little room in between.
- Peppers — Needs real sustained warmth to set fruit — get that right in your climate and it rewards you for months.
- Eggplant — Slow to establish and fussy about heat, but produces like little else once it's away.
- Sweet corn — Needs a block planting for reliable pollination rather than a single row — true in every climate it's grown.
- Broccoli — A narrow window between cold enough to head up and warm enough to bolt, wherever you garden.
- Brussels sprouts — Slow and space-hungry, with the same pest pressure as broccoli and cabbage — but few crops reward patience like it does.
- Kale — The most cold-hardy common brassica, and it measurably sweetens after frost — worth the space wherever winters allow it to stand.
- Cauliflower — The trickiest common brassica — firm soil and even moisture decide whether you get a curd at all.
- Celery — Thirsty and slow, and it wants trenching — most gardeners either love growing it or skip it.
- Grain amaranth — An unusual grain crop for anyone with space to experiment — sow warm, harvest the seed heads in autumn.
- Love-lies-bleeding amaranth — The ornamental cousin of grain amaranth, grown as much for the trailing flowers as the edible leaves.
Plant once, harvest much later
These don't run on a normal sowing-to-harvest rhythm. Plant them, do very little for months, and the payoff arrives on its own schedule — sometimes not until next year.
- Garlic — Planted once, left alone for months, lifted much later — about as close to set-and-forget as vegetable growing gets, in any climate.
- Sweet potatoes — A full stretch of sustained warmth from slip to harvest, with very little attention needed in between.
- Winter squash — A long season from sowing to a storage-ready fruit, but what you get keeps for months afterward.
- Strawberries — Plant a bed once and it crops every summer for three or four years before it needs renewing.
- Elephant garlic — A leek relative with garlic-sized ambitions — plant like garlic, but give the giant cloves real room.
- Pumpkins — Wants space and feeding more than skill; the reward is sized by how much room you give it.

Where gardeners lose a season
Gardening from imported advice produces a recognisable set of failures, and almost all of them come from a date that was true somewhere else.
| What goes wrong | Why it happens | Where to read the fix |
|---|---|---|
| Lettuce and spinach bolt within weeks | Sown into a season that is already warming, following a calendar written for a cooler latitude. | Lettuce · Spinach |
| Tomatoes flower but set no fruit | Sustained temperatures above roughly 30 °C day or 21 °C night. Pollen loses viability; the plant looks healthy and produces nothing. | Tomatoes |
| Onions never bulb | A day-length-sensitive cultivar grown at a latitude where the trigger never arrives. Nothing you do to the soil fixes this. | Alliums |
| Seed sown in warm soil still fails | Soil too warm, not too cold — lettuce germination fails above about 25 °C, which surprises people who only know the cold-end thresholds. | When to plant |
| Everything drowns in the wet season | Planted on the temperate schedule, so the crop meets the monsoon at its most vulnerable stage. | Bush beans |
| Southern-hemisphere timing is six months out | Following northern-hemisphere months directly rather than translating them. | The seasonal wheel |
Every one of these is fixed the same way: stop reading dates, start reading conditions.
From guides to a plan
The guides give you the thresholds. The planner is where your own readings live.
These guides describe what each crop needs. Turning that into a schedule means recording what your garden actually does — soil temperature at seed depth, the date frost really arrived, what you sowed and what came up — season after season, until the numbers belong to you rather than to a region.
The Global Vegetable Garden Planner is the printable system for exactly that: a soil-temperature reference for every crop, a frost-date record you fill in yourself, bed layouts, four-year rotation, seed inventory, sowing log and harvest tracker. No calendar dates, because they would be wrong for most people reading this.
Frequently Asked Questions
Why are there no planting dates in these guides?
Because a date is only meaningful at one latitude in one hemisphere. Soil temperature, frost tolerance and day length are the conditions the plant actually responds to, and those are the same everywhere.
How do I work out my own planting times?
Measure soil temperature at 5-10 cm each morning, record your own first and last frost dates, and match those against each crop's temperature class. That gives you a schedule specific to your garden rather than your region.
How many crops do these guides cover?
22 vegetables, each described by temperature class, germination requirements, spacing and days to maturity rather than by calendar month.

Crops that actually help each other
Most companion-planting advice is folklore rather than evidence -- Garden Organic itself notes there is "not much scientific evidence to support many of the claims made." These four pairings are the ones we could trace to a named source; the rest of the guides below list crop-rotation warnings (shared pests and diseases) rather than positive pairings.
- The Three Sisters -- Sweetcorn, Runner Beans and Pumpkins: a traditional Native American polyculture (Garden Organic). The corn gives the beans something to climb, the beans (a legume) fix nitrogen that benefits the corn, and the pumpkin's sprawling foliage shades the soil to suppress weeds.
- Carrots + Onions -- mutual scent-masking may reduce carrot fly and onion fly (Garden Organic); treat as plausible rather than proven.
- Tomatoes + Sweet Basil -- basil is a non-host plant for glasshouse whitefly; interplanting reduced whitefly populations on tomato in a season-long glasshouse trial (PLOS ONE, 2019).
- Strawberries + Borage -- borage attracts pollinators that benefit the strawberry crop.
