Garlic, with its pungent aroma and robust flavor, is a kitchen staple that thrives when planted at the right time. In the UK, where seasons play a crucial role in gardening, knowing when to plant garlic is essential for a bountiful harvest. This article serves as your guide to the optimal timing, preparation, and techniques for planting garlic in the UK.

When To Plant Garlic UK

1. Understanding Garlic Varieties

1.1 Softneck vs. Hardneck Garlic

Before delving into planting times, it’s important to understand the types of garlic. Softneck and hardneck are the two main varieties. Softneck varieties are well-suited to milder climates, making them ideal for UK gardens. Hardneck varieties, while hardy, are better suited to colder regions.

2. Choosing the Right Garlic Bulbs

2.1 Quality Over Quantity

Selecting high-quality garlic bulbs is crucial for a successful crop. Opt for firm, disease-free bulbs with intact cloves. Consider purchasing garlic bulbs from reputable suppliers or local farmers’ markets to ensure they are well-suited to the UK climate.

3. Timing for Planting Garlic in the UK

3.1 Fall Planting

In the UK, fall is the prime time for planting garlic. Aim for a planting window between late September and November. Planting during this period allows garlic cloves to establish strong roots before winter sets in, ensuring a robust start to the growing season.

3.2 Winter Chilling Requirement

Garlic requires a period of cold temperatures to stimulate bulb formation. By planting in the fall, garlic cloves experience the necessary chilling period during winter, promoting healthy growth and development.

4. Preparing the Soil

4.1 Well-Drained Soil

Garlic prefers well-drained soil with a slightly acidic to neutral pH. Ensure the chosen planting site receives adequate sunlight and has good drainage to prevent waterlogging, which can lead to rot.

4.2 Adding Organic Matter

Enhance the soil’s fertility by incorporating organic matter, such as well-rotted compost or aged manure. This not only provides essential nutrients but also improves soil structure, promoting optimal root development.

5. Planting Techniques

5.1 Separating and Planting Cloves

Break apart the garlic bulb into individual cloves, ensuring each clove is intact with its papery covering. Plant each clove pointed end up, about 2 inches deep and 6 inches apart, in rows spaced around 12 inches apart.

5.2 Mulching for Winter Protection

After planting, apply a layer of mulch, such as straw or well-rotted leaves, to insulate the soil and protect garlic cloves from harsh winter temperatures. Mulching also helps suppress weeds and retain soil moisture.

6. Spring Care and Maintenance

6.1 Fertilizing in Spring

As spring arrives, provide a balanced fertilizer to support garlic growth. Avoid high-nitrogen fertilizers, as they can encourage excessive foliage growth at the expense of bulb development.

6.2 Watering Considerations

Garlic prefers consistently moist soil, especially during the bulb development stage. Water regularly, ensuring the soil remains evenly moist but not waterlogged. Reduce watering as the garlic approaches maturity to avoid rot.

7. Harvesting Garlic

7.1 Signs of Maturity

Knowing when to harvest garlic is essential for optimal flavor and storage. Harvest when the lower leaves turn yellow and begin to wither. Dig up the bulbs, being careful not to damage them, and allow them to cure in a dry, well-ventilated area for several weeks.

7.2 Storing Garlic

Once cured, trim the roots and remove excess dirt, leaving the outer skin intact. Store garlic bulbs in a cool, dry place with good air circulation. Proper storage ensures an extended shelf life and preserves the garlic’s distinct flavor.


Planting garlic in the UK involves careful consideration of timing, soil preparation, and cultivation techniques. By adhering to the fall planting schedule, providing well-drained soil enriched with organic matter, and following through with spring care, you can cultivate robust garlic bulbs that add a burst of flavor to your culinary creations. Embrace the seasonal rhythms of garlic cultivation, and you’ll be rewarded with a bountiful harvest that enhances both your garden and your kitchen.
