How Long Does Garlic Take to Grow?

Introduction

Garlic is one of the most rewarding crops to grow at home. It’s easy to plant, doesn’t take much space, and provides bulbs that can last for months once harvested. But many new gardeners often ask: how long does garlic take to grow?

The answer depends on when you plant it, the variety you grow, and your local climate. In the UK, garlic takes 7–9 months from planting to harvest, but factors like soil preparation, watering, and weather conditions can speed up or slow down the process.

This guide breaks down the garlic growing timeline so you know what to expect at each stage, from planting cloves to lifting fully formed bulbs.

Garlic Growing Timeline at a Glance

• Autumn-planted garlic: 8–9 months (plant in September–November, harvest June–July).
• Spring-planted garlic: 6–7 months (plant in February–March, harvest July–August).
• Elephant garlic: 8–10 months (longer growing season).

Factors That Affect Garlic’s Growing Time

1. Planting Season

• Autumn garlic: Needs cold weather to split cloves into bulbs. Longer season, but larger bulbs.
• Spring garlic: Shorter season, grows quicker but may produce smaller bulbs.

2. Variety

• Hardneck garlic: Typically matures earlier (but doesn’t store as long).
• Softneck garlic: Takes slightly longer but stores up to 9 months.
• Elephant garlic: Needs extra time — up to 10 months.

3. Climate

• Garlic grows best in cooler climates.
• Mild winters may slow down bulb splitting.
• Hot, dry springs may shorten the growing season.

4. Growing Conditions

• Well-prepared, fertile soil speeds up growth.
• Watering during bulb formation is crucial.
• Poor drainage or lack of nutrients slows growth.

Month-by-Month Garlic Growth Stages

September–November (Autumn Planting)

• Plant cloves in fertile, well-drained soil.
• Roots begin developing before winter.
• Some shoots may appear before frost.

December–February

• Growth slows in cold weather.
• Garlic remains dormant but roots continue to develop underground.

March–April

• Shoots grow taller and greener as daylight increases.
• Plants need nitrogen-rich feeding.

May–June

• Bulbs begin swelling.
• Consistent watering is essential at this stage.

June–July

• Autumn garlic is ready to harvest when lower leaves yellow.
• Stop watering 2 weeks before harvest.

July–August

• Spring garlic is ready for harvest.
• Lift carefully, cure for storage.

How to Tell Garlic is Mature and Ready to Harvest

• Bottom leaves are yellow, but top leaves are still green.
• Bulbs feel firm and fully formed when lifted.
• Papery skins are intact around the bulb.

Can Garlic Grow Faster?

Garlic has a natural growth cycle, so it cannot be dramatically sped up. However, you can encourage healthy, quicker development by:

• Planting at the right time (autumn for bigger bulbs).
• Using certified seed garlic.
• Preparing soil with compost or organic fertiliser.
• Watering consistently in spring and summer.
• Removing scapes (hardneck garlic) to redirect energy to bulbs.

Growing Garlic in Containers: Does It Take the Same Time?

Yes, garlic in pots takes the same amount of time to grow as in beds. However:

• Pots dry out faster, so more frequent watering is needed.
• Containers should be at least 20–30cm deep.
• Feeding is more important due to nutrient loss in pots.

Elephant Garlic: Longer Growing Time

Elephant garlic can take up to 10 months to mature. It may also form single-clove “rounds” if conditions are poor, which will need another season to develop into full bulbs.

Conclusion

So, how long does garlic take to grow? In most UK gardens, garlic needs 7–9 months from planting to harvest. Autumn planting gives the biggest bulbs, while spring planting is quicker but may result in smaller harvests. Elephant garlic takes even longer but rewards you with massive, mild-flavoured bulbs.

With patience, proper care, and attention to timing, garlic will reliably provide you with one of the most useful and flavourful crops for your kitchen.

Top 10 Questions About Garlic Growing Time

1. How many months does garlic take to grow?
Usually 7–9 months, depending on when you plant.

2. Can garlic grow in 3 months?
No, garlic has a long growing cycle and needs at least 6 months.

3. How long does autumn garlic take to grow?
8–9 months, planted in autumn and harvested in early summer.

4. How long does spring garlic take to grow?
6–7 months, planted in February–March and harvested in late summer.

5. Does elephant garlic take longer to grow?
Yes, up to 10 months.

6. Can I speed up garlic growth?
Not significantly — but good soil, watering, and feeding help it grow strong.

7. Why is my garlic taking so long to grow?
Poor soil, lack of sunlight, overcrowding, or insufficient watering can slow growth.

8. How do I know garlic is ready?
When bottom leaves turn yellow but top leaves remain green.

9. Can garlic be harvested early?
You can pull immature garlic (“green garlic”), but bulbs will be small and not store well.

10. What happens if I leave garlic in the ground too long?
Bulbs may split, reducing storage life.
