Garlic is a rewarding crop that’s relatively easy to grow, provided you get the timing right. With our cooler climate, it's essential to understand when to plant garlic to ensure a successful harvest.
Quick Answer
The best time to plant garlic in the UK is in autumn, from late September to November, or in early spring, around February to March, depending on your local climate.
Understanding the UK Climate
The UK’s climate is ideal for garlic, which requires a period of cold to develop the best bulbs. In Staffordshire and across the Midlands, we experience relatively mild winters and cool summers, making it a perfect setting for garlic growing.
When to Plant Garlic
Autumn Planting
Autumn is the traditional time to plant garlic. Planting from late September to November allows the cloves to establish roots before the cold winter sets in. This period gives the bulbs a head start, leading to larger and more robust garlic heads by summer.
Spring Planting
If you miss the autumn window, don’t worry. You can plant garlic in early spring, around February to March. While spring-planted garlic may not be as large as autumn-planted bulbs, it can still produce a good yield.
Planting Tips for Success
- Choose a sunny spot with well-drained soil.
- Space the cloves 10-15cm apart in rows 30cm apart.
- Plant cloves with the pointed end facing up, about 2.5cm deep.
- Mulch with straw or wood chips to retain moisture and suppress weeds.

Frequently Asked Questions
Can I plant garlic bought from the supermarket?
While you can try planting supermarket garlic, it's often treated to prevent sprouting and might not perform well. Seed garlic from a garden centre is a better option.
How do I know when my garlic is ready to harvest?
Garlic is usually ready to harvest when the leaves turn yellow and start to die back, typically in July or August for autumn-planted garlic.
What should I do if my garlic starts to sprout before planting?
If your garlic starts sprouting early, plant it as soon as possible. Garlic is hardy and can handle a bit of early growth in the ground.
