Garlic might be the easiest vegetable you will ever grow. You push cloves into the ground on an autumn afternoon, ignore them for eight months, and pull up fat, flavourful bulbs in summer that put shop garlic to shame. It needs no feeding schedule, no pruning, and barely any watering — winter does most of the work for you.
The catch? There is only one, and it is timing: garlic must be planted in autumn — October and November across Central and Western Europe — because the cloves need winter cold to split into proper bulbs. Miss the window and you miss the crop. So if you are reading this in October, this weekend is the moment.
| Care point | What garlic needs |
|---|---|
| Sun | Full sun — the sunniest bed you have |
| Water | Very little; winter rain is usually enough |
| Soil & pH | Well-drained, not too rich; pH 6.0–7.0; hates waterlogging |
| Plant (Central Europe) | October to November — this is the window |
| Spacing | 15 cm between cloves, rows 25–30 cm apart |
| Days to harvest | ~240 days; harvest June–July |
| Difficulty | Very easy — the ultimate plant-and-forget crop |
Step 1: Buy proper planting garlic — not supermarket bulbs
This matters more than any technique. Supermarket garlic is usually grown in warm climates from varieties unsuited to our winters, and it may carry disease. Buy certified disease-free planting garlic from a garden centre or seed supplier — it costs little and the difference in results is enormous.
Choose hardneck varieties (like Music or Chesnok Red) for the biggest flavour and cold hardiness, or softneck varieties (like Germidour or Picardy) for longer storage and braiding. If you are unsure, Germidour is a superb beginner choice: reliable, early, and stores well.
Step 2: Plant in October or November — pointy end up
Break each bulb into individual cloves just before planting (not days earlier — they dry out). Keep the papery skin on and choose the biggest, healthiest cloves; small damaged ones go in the kitchen, not the soil.
Push each clove 5 cm deep, pointy end up, 15 cm apart, in rows 25–30 cm apart. In heavy soil, plant slightly shallower and into a ridge so water drains away. Then walk away — seriously, that is planting done. A mulch of straw over the bed keeps weeds down and the soil temperature steady.
Step 3: Give it sun and drainage — the only two demands
Garlic's two non-negotiables are full sun and soil that drains. It rots in waterlogged ground faster than almost any vegetable, so if your soil stays soggy in winter, plant into a raised bed or even deep pots and containers instead — garlic grows perfectly well in a 20 cm deep pot.
Do not enrich the bed heavily: garlic prefers ordinary soil over rich. A bed that grew hungry crops like tomatoes or zucchini last summer, with no fresh manure, is ideal. This makes garlic the perfect follow-on crop — see our October checklist for what to clear first.
Step 4: Ignore it all winter (mostly)
Green shoots will appear within weeks — sometimes before Christmas. Do not worry when frost blackens the tips; garlic is extremely hardy and the plants shrug it off. You do not need to water (winter rain suffices), feed, or protect them.
The one winter job: keep weeds down. Garlic hates competition, and its narrow leaves cast little shade. A quick hoe on a dry day every few weeks, or a straw mulch from the start, keeps the bed clean with minimal effort.
Step 5: A little spring care for bigger bulbs
When growth accelerates in March and April, garlic appreciates a single feed of balanced fertiliser if your soil is poor — but do not overdo it, and stop feeding by May. If spring is very dry, water during the bulb-swelling weeks of May and June; then stop watering entirely as harvest approaches, which helps the bulbs dry and store well.
On hardneck varieties you will see curly flower stalks (scapes) appear in early summer. Snap them off — this directs energy into the bulb, making it noticeably bigger. And do not throw scapes away: they are delicious grilled, stir-fried, or made into pesto.
Step 6: Harvest when the leaves tell you
Garlic tells you when it is ready: when the lower third of the leaves have yellowed and flopped, usually late June to July. Do not wait until all the leaves are brown — overripe bulbs split open in the ground and will not store.
Loosen with a fork (do not pull — the stems tear), and lift on a dry day if you can. Brush off loose soil but do not wash the bulbs; they need to dry with their skins on.
Step 7: Dry, cure, and store for months
Curing is what turns fresh garlic into keeping garlic. Lay the plants somewhere warm, dry, and airy — a shed, garage, or covered porch — for 2–4 weeks, until the necks are completely dry and papery. Good airflow matters more than heat.
Once cured, trim the roots, cut stems to a few centimetres (or braid softneck stems), and store in a cool, dry, dark place. Well-cured garlic keeps 6–8 months — your October planting feeding you until the following summer. Save your biggest bulbs for replanting next October, and the cycle becomes self-sustaining.
Troubleshooting: common garlic problems
Cloves rotted in the ground over winter: Waterlogged soil — the number one garlic killer. Next time, plant into a raised bed or ridge, improve drainage with grit, or grow in pots. In persistently wet gardens, plant in February instead (smaller bulbs, but a crop beats none).
Small bulbs at harvest: Usually planted too late (missing winter cold), too shallow, or harvested from supermarket garlic. Plant certified stock in October, 5 cm deep, in full sun — size follows.
Leaves yellow early with stunted growth: Could be onion white rot (fluffy white mould at the base — destroy affected plants, do not compost, and do not grow onions or garlic there for several years) or simply nitrogen hunger in poor soil. A spring feed rules out the simple cause first.
Rust (orange spots on leaves): Common but rarely fatal. Improve airflow with proper spacing, avoid wetting foliage, and remove badly affected leaves. The bulbs underneath are usually fine.
What to do this October
It is October — plant now. This is not a "sometime this autumn" job where procrastination is harmless; every week of delay in October/November costs root establishment before winter. Buy certified planting garlic this week, plant this weekend: 5 cm deep, pointy end up, 15 cm apart, sunniest spot. Mulch with straw. Then check it off and enjoy the smug feeling of a crop already growing while the garden sleeps. Full details of the month's other jobs are in our October checklist.
Frequently asked questions
Can I plant garlic from the supermarket?
It will usually sprout, but results are poor: wrong varieties for our climate, possible disease, and often treated to prevent sprouting. Certified planting garlic costs little and performs enormously better. This is the one shortcut not worth taking.
What is the difference between hardneck and softneck?
Hardneck makes a flower stalk (scape), has bigger, more complex flavour, and suits cold winters — but stores 4–6 months. Softneck has no scape, braids beautifully, and stores 8–12 months. Beginners in Central Europe do well with either; Germidour (softneck) is the safest first pick.
Can I grow garlic in pots?
Yes — a pot at least 20 cm deep, well-drained compost, full sun. Plant cloves 10 cm apart in pots. Container garlic actually avoids the waterlogging that kills in-ground crops in wet winters.
My garlic sprouted in November — will frost kill it?
No. Garlic is extremely frost-hardy; autumn shoots routinely survive -15°C under snow or mulch. Blackened leaf tips in hard frost look alarming but the plant recovers fully in spring.
