Garlic is best planted in the UK from October to November, giving the cloves plenty of time to establish before spring. You can still plant through winter if the ground is workable and well drained, while February to March provides a useful spring planting window.
The main thing is not to force garlic into saturated soil simply because the calendar says it is time to plant.
When to Plant Garlic in the UK
Garlic has a fairly long planting season in the UK. Autumn is generally best, but soil and weather conditions matter more than hitting one exact date.
| Month | Planting Advice |
|---|---|
| September | Some varieties can be planted now, although October–November is the main autumn window. |
| October–November | Main autumn planting window for most UK garlic. |
| December–January | Still suitable if the soil is workable, unfrozen and not waterlogged. |
| February | A good spring planting opportunity if you missed autumn. |
| March | Still worth planting, although bulbs have less time to develop. |
| April | Late, but planting can still be worthwhile with suitable varieties. |
If your soil is saturated when you planned to plant, wait for workable conditions rather than planting into waterlogged ground.
My pick: Garlic ‘Solent Wight AGM’
A dependable UK all-rounder with good-sized bulbs, strong flavour and excellent storage. It’s a particularly good choice if you want one reliable garlic variety for the plot.
Is It Better to Plant Garlic in Autumn or Spring?
Autumn planting is generally preferable because garlic has longer to establish and develop before harvest. It is particularly useful for hardneck varieties, which benefit from winter cold.
Spring planting is a useful alternative if autumn was missed or the ground was too wet. Garlic planted later has less growing time, so bulbs may be smaller.
Aim to plant as early as conditions allow and always check the instructions supplied with your variety, as some garlic is better suited to spring planting than others.
Does Soil or Weather Change When You Should Plant Garlic?
Yes. Garlic needs free-draining soil, and cloves can rot if they sit in saturated ground for long periods.
If conditions are waterlogged when you planned to plant, wait until the soil becomes workable or use a better-drained raised bed or container.
Local soil and weather conditions are more useful than rigid regional planting dates. A well-drained bed may be ready to plant while heavy clay nearby is still too wet.
Hardneck vs Softneck Garlic Planting Times
The type of garlic you are growing can affect the best planting time.
| Type | Best Planting Time |
|---|---|
| Hardneck garlic | Generally best planted in autumn so it experiences winter cold. |
| Softneck garlic | Usually planted in autumn, although some varieties are also suitable for spring planting. |
Always check the recommended planting period for the individual variety you are growing.
What to Do After Planting Garlic
Once planted, garlic needs very little immediate attention. Avoid waterlogged conditions and only water if the soil becomes unusually dry.

What Comes Next?
Once your garlic is planted, use the How to Grow Garlic in the UK guide for ongoing care and When to Harvest Garlic when the crop begins to mature in summer.
You can also add garlic to the Backyard Farmer Allotment Planner to include it alongside the rest of your planting plan.
Conclusion
October to November is the main garlic planting window in the UK, but winter planting is still possible in workable, well-drained soil. If you miss autumn, February to March gives you another opportunity.
Use the condition of the soil rather than one fixed planting date as your guide.
