Growing Garlic In the UK? Explainer for Beginners!

Did you know that growing garlic in the UK is relatively easy? The key is to plant them in the proper growth environment during the recommended growing season so that you can have the kind of harvest that you’ve always hoped for.

Knowing How To Plant And Grow The Two Main Types Of Garlic

There are two main types of garlic – soft neck garlic or artichoke garlic and stiff neck garlic or top-setting garlic. You have to find out which garlic varieties thrive in the southern half of the UK and which ones match your cooking purposes and your taste buds. It’s important to note that growing garlic isn’t the same for each variety.

Softneck garlic

Although soft neck varieties don’t usually produce a flower scape, they tend to mature earlier and produce more cloves than the hardneck types. Furthermore, they tend to grow best in areas that experience mild winters and hot summers.

If you plan to make beautiful and long-lasting garlic heads’ braids, it’s best to grow softneck types such as Silver Rose and Siciliano. You’ll know that it’s time to plant your soft neck garlic when you’re planting your spring-flowering bulbs.

You can reap a harvest the following spring, summer, or early autumn if you plant your garlic in the autumn. Be sure to plant the cloves with their pointed ends facing upward. While you’re at it, keep in mind that you’ll need to plant them at least 6 inches apart and about 4 inches deep.

Hardneck garlic

Hardneck garlic varieties are known to be very hardy. Whether you plant them in areas with warm climates or cold winters, you can still expect them to provide you with a bountiful harvest. However, when you grow them in places where the temperature is warmer, they tend to produce smaller heads than hard neck garlic, which owners plant in much colder areas.

A great way to improve the yield is to make sure that one cuts off the flower scapes as soon as you notice them curling around on themselves. By getting rid of the flower scapes, you’ll cause the plant to direct all of its energy toward the production of garlic cloves.

When Is The Best Time To Plant Garlic In the UK?

As previously mentioned, the best time to plant garlic in the UK is in the autumn. Even if you accidentally left some garlic cloves in the ground during the summer season, these won’t begin to show growth signs until the autumn. In other words, you shouldn’t expect garlic to sprout right away if you plant them in the summer because they tend to wait for autumn conditions before they do so.

Make sure that you plant your garlic cloves in a sunny area. They also grow best when you plant them in well-drained soil.

Where Does Garlic Grow In the UK?

Colin Boswell happens to be the biggest garlic grower in the UK, with over 50% of its garlic crops grown. Furthermore, his company locates strategically in an area where the climate and soil quality are ideal for growing these crops.

The individual cloves that the farmer broke off from the whole garlic head will multiply once the owner plants them in the ground. To give you an idea, each of these cloves will potentially produce a bulb consisting of about 5 to 10 cloves.

When Is Garlic Ready For Harvest?

Your garlic crops will be ready for harvest when it’s late spring or summer. Keep an eye out for green leaves starting to turn brown and green flower scapes beginning to soften.
