Garlic is one of the easiest crops to grow in a UK garden or allotment. Plant individual cloves in autumn, give them full sun and free-draining soil, and they’ll establish roots through winter before putting on strong growth in spring.
For most UK growers, October to December is the best time to plant garlic, although suitable varieties can also be planted later in winter or early spring. Once established, garlic needs little more than weeding, occasional watering and a spring feed if your soil is poor.
When to Plant Garlic in the UK
For most UK gardeners, October to December is the best time to plant garlic.
Autumn planting gives cloves time to establish before spring and provides the cold period most varieties need for good bulb and clove development.
Autumn Planting
October and November are ideal in many parts of the UK, but planting into December is normally fine if the ground is workable.
Garlic is hardy and benefits from winter cold. Wet, waterlogged soil is usually a bigger problem than frost.
If your ground stays saturated over winter, use a raised bed, container or start the cloves in modules instead.
Can You Plant Garlic in Spring?
Yes.
Suitable varieties can still be planted from January through to March, and spring-planted garlic can produce a good crop.
However, results become less predictable the later you plant because the cloves receive less winter cold.
If you’ve missed autumn, it’s usually still worth planting suitable garlic rather than giving up on the crop.
For more detail, see our guide to when to plant garlic in the UK.
Choosing Garlic to Grow
Garlic is generally sold as either hardneck or softneck.
Both can grow well in the UK, but there are a few useful differences.
Hardneck vs Softneck Garlic
| Softneck Garlic | Hardneck Garlic | |
|---|---|---|
| Flower stalk | Usually none | Produces a scape |
| Storage | Usually longer | Usually shorter |
| Cloves | Often more numerous | Usually fewer and larger |
| UK growing | Very reliable | Also grows well with suitable varieties |
If long storage is your priority, softneck garlic is often the better choice. Hardneck varieties are worth growing for their larger cloves and edible scapes.
Good Garlic Varieties for UK Gardens
A few established choices include:
- Solent Wight – reliable softneck garlic with excellent storage potential.
- Germidour – productive softneck with attractive purple-marked bulbs.
- Carcassonne Wight – hardneck garlic suited to UK growing conditions.
- Lautrec Wight – hardneck variety producing well-flavoured cloves.
BYF Pick: Solent Wight
Solent Wight is a reliable UK softneck with excellent storage potential.
You may also see bulbs labelled as seed garlic. This usually means garlic specifically produced and sold for planting rather than botanical seed.
Where to Grow Garlic
Garlic grows best in full sun and fertile, free-draining soil.
Improve poorer soil with well-rotted garden compost before planting, but avoid freshly manured ground.
Heavy clay doesn’t automatically rule garlic out, although raised beds can make growing much easier where drainage is poor. Containers are another good option for smaller spaces or difficult soil.
How to Plant Garlic Cloves
Garlic is normally grown from individual cloves rather than seed.
Step 1: Break the Bulb Into Cloves
Separate the bulb shortly before planting.
Choose firm, healthy cloves and leave the papery skins intact. Larger cloves generally give plants a stronger start.
Step 2: Position the Cloves
Plant each clove with:
- the pointed end facing upwards
- the flatter root plate facing down
Step 3: Space Your Garlic
Leave roughly:
- 10–15cm between cloves
- 25–30cm between conventional rows
Avoid crowding, as the bulbs need room to develop.
Step 4: Plant at the Right Depth
Plant each clove so the tip sits around 2.5–3cm below the soil surface.
You can plant slightly deeper in light, sandy soil. On heavy ground, avoid burying cloves unnecessarily deep where they’re more likely to sit wet.
Step 5: Cover and Water
Cover with soil and firm gently.
If the ground is already damp in autumn, you may not need to water. Give dry soil a light watering to settle the cloves in, but don’t saturate it.

How to Grow Garlic in Pots
Garlic grows well in containers and is a useful option for patios, smaller gardens or ground that stays too wet over winter.
Choosing a Container
Use a pot at least 25cm deep with plenty of drainage holes.
The width determines how many cloves you can grow while still keeping them properly spaced.
Compost and Spacing
Use a good peat-free multipurpose compost.
Leave roughly 10–15cm between cloves where possible and avoid cramming too many plants into a small container.
Position and Watering
Place the pot in full sun.
Through winter, concentrate on preventing waterlogging. As growth speeds up in spring, check containers more often because compost can dry much faster than open ground.
Does Garlic Need Winter Protection in Pots?
Garlic is hardy and normally needs no special winter protection.
Good drainage matters more than insulation. If a container is extremely exposed, move it somewhere more sheltered while keeping it outdoors.
How to Care for Garlic
Once established, garlic is a fairly low-maintenance crop.
Watering Garlic
Outdoor garlic usually needs little watering through autumn and winter.
Water during prolonged dry spells in spring and early summer while the bulbs are developing.
Stop regular watering once the bulbs are well developed and the foliage starts yellowing.
Feeding Garlic
Garlic doesn’t need constant liquid feeding if it is growing in reasonably fertile soil.
Compost added before planting will usually give it a good start. On poorer ground or in containers, a light general-purpose feed in spring can help.
Avoid overfeeding with nitrogen, which can encourage excessive leafy growth.
Weeding
Keep the bed reasonably weed-free through spring.
Garlic doesn’t compete well with heavy weed growth, so remove weeds before they become established. Take care when hoeing because developing bulbs sit fairly close to the surface.
Removing Garlic Scapes
Hardneck varieties produce a curled flower stalk called a scape.
Remove scapes while they are young so the plant can concentrate on bulb development.
They’re also edible and have a mild garlic flavour.
Garlic Growing Calendar
| Time | What to Do |
|---|---|
| October–December | Plant garlic cloves |
| January–February | Check drainage and leave plants largely alone |
| March–April | Weed and feed if needed |
| May–June | Water during dry spells and remove hardneck scapes |
| June–August | Harvest as the lower leaves begin to yellow |
| July–August | Cure and store harvested bulbs |
Treat this as a rough UK guide rather than a fixed timetable. Variety, planting date, location and weather can all shift the crop forwards or backwards.
Common Garlic Problems
Garlic is usually straightforward to grow, but a few problems are worth recognising.
Garlic Rust
Garlic rust causes distinctive orange pustules on the leaves and is common on UK allotments.
A late infection doesn’t necessarily ruin the crop, but severe rust earlier in the season can reduce bulb size by damaging healthy foliage while the bulb is still developing.
Good spacing and sensible feeding help keep plants healthy, although rust can still appear when conditions favour it.
Onion White Rot
White rot is a more serious problem.
Affected plants can yellow and wilt, while the roots and base of the bulb develop white fungal growth and begin to rot.
The disease can survive in contaminated soil for many years, making it particularly troublesome on allotments. Remove badly affected plants and avoid moving contaminated soil around the plot.
Allium Leaf Miner
Allium leaf miner attacks garlic, onions, leeks and related crops.
Damage can include distorted leaves, mines in the foliage and larvae or brown pupae inside the plant.
Where it is a recurring problem, insect-proof mesh during adult activity can help prevent egg laying.
Rot and Waterlogging
Garlic bulbs are much more likely to rot in saturated ground.
If your soil stays wet through winter, improve drainage or consider raised beds, containers or module planting.
Birds Pulling Up Garlic
Birds sometimes pull newly planted cloves or shoots from loose soil.
Temporary netting or mesh can help until the plants establish.
Why Are My Garlic Bulbs Small?
Common causes include:
- late planting
- insufficient cold exposure
- overcrowding
- too much shade
- dry conditions during bulb development
- poor soil
- pest or disease problems
Are Yellow Garlic Leaves a Problem?
Not necessarily.
Yellowing lower leaves are normal as garlic reaches maturity and are one of the main harvest signs.
Yellowing much earlier in the season, particularly alongside weak growth or rot, is when you should investigate further.
When to Harvest Garlic
Garlic is usually ready between June and August, but the plant itself is a better guide than the calendar.
Look for:
- several lower leaves turning yellow or brown
- some upper leaves still remaining green
Don’t wait until all the foliage has completely died.
Leaving garlic in the ground too long can cause the bulb wrappers to break down and individual cloves to start separating, which reduces storage life.
How to Lift Garlic
Loosen the soil beside the bulb with a garden fork and lift carefully rather than pulling on the foliage.
Handle freshly lifted bulbs carefully to avoid bruising.
For more detail, see our full guide to when and how to harvest garlic.
How to Cure and Store Garlic
Garlic intended for storage needs to dry properly after harvest.
Curing Garlic
Brush off loose soil but don’t wash bulbs you plan to store.
Cure them somewhere dry, shaded and well ventilated.
A shed, garage, covered outdoor area or ventilated rack can all work.
Curing normally takes around two to four weeks, although the condition of the bulb matters more than the exact number of days.
Garlic is ready to store when:
- the outer skins feel papery
- the neck is completely dry
- the bulb feels firm
Storing Garlic
Once cured, trim the roots and stems if required.
Store bulbs somewhere cool, dry and airy. Mesh bags, open baskets or hanging braids all work well.
Softneck varieties generally store longer than hardnecks.
Can You Save Garlic Cloves to Plant Again?
Yes.
Save healthy, well-formed bulbs and replant the largest sound cloves.
Don’t save cloves from plants showing serious disease. If problems begin building up in your crop, switching back to fresh planting stock can be sensible.
Garlic FAQs
Yes. Supermarket garlic can grow successfully.
However, named garlic sold specifically for planting is generally a more predictable choice because you know the variety and that it is intended for growing.
Yes. Suitable varieties can be planted from January into early spring, although autumn planting is generally more reliable.
Garlic can sometimes produce a single round bulb rather than dividing properly.
Late planting or insufficient exposure to cold are common reasons, although variety and seasonal conditions can also play a part.
Yes. Young garlic scapes are edible and have a mild garlic flavour. Remove them from hardneck plants while they’re still tender.
