My passion is sharing my knowledge about gardening, and helping them to see how easy it can be to grow their own food. There’s nothing better than seeing someone’s face light up when they taste something they’ve grown themselves! Reaping the rewards of planting garlic cloves is one of those moments.
Continue reading for my top tips on growing and harvesting homegrown garlic. Your stir fries, soups, pastas and curries will never taste the same again.
So, let’s crack on with how easy it is to grow garlic.
#1. Identify the right place for growing garlic
To grow garlic successfully the planting location needs to be a sunny spot, preferably located in full sun with a well drained soil.
Don’t worry if your soil is not free draining. Heavy soil can be remedied by digging in garden compost or well rotted manure before planting the individual garlic cloves.
Digging in either of these will help with drainage & provide food and nutrients to your developing bulbs.
If growing in pots and planters the same applies. A sunny position with a free draining compost.
#2. Choosing the right type of garlic to grow
There are 2 types of garlic that are easily grown in the UK, they are called softneck and hardneck garlic.
Garlic can be both Spring planted garlic for late summer harvesting and Autumn planted garlic for early summer harvesting the following year.
Softneck garlic does better in milder parts of the UK and can be planted in both Spring and Autumn. Wheres as ‘hardneck’ varieties need a period of cold weather so really only suitable for late Autumn planting.
Within ‘Soft & Hardneck’ types of garlic there are many varieties. From mild flavour types such as the huge elephant garlic to strong and punchy flavours such as Cledor.
I’m a garlic fiend and love growing garlic as it requires little attention until harvest time. Living in the South of England I usually plant both types in Autumn and plant softneck garlic in Spring.
#3. Planting the Garlic Cloves
Once you have your certified garlic bulbs from a garden centre or on-line retailer it’s time to plant garlic.
Supplied as whole garlic bulbs they need to be carefully broken down into individual garlic cloves . Depending on the variety each bulb can render up to 18 individual cloves.
Planting garlic cloves could not be simpler….
If there hasn’t been the need to cultivate the soil and improve its structure with compost then a sprinkling of fertiliser is advised. Blood, fish & bone or equivalent is good.
We’ve all seen a clove before. They have a flat end and a pointy end. It is the pointy end that needs to face upwards when you plant garlic.
Push the clove into the soil so the top of the garlic clove is approx 1-2″ below the soil surface Lightly cover with soil so the top of the clove is not visible.
Individual cloves need to be spaced 10cm apart with 30cm between rows. I have produced this little graphic to show how many coves can be planted in a 1m x 1m space.
This has never happened to me but pigeons can take a fancy to newly planted cloves. Avoid this by covering the planted area with a horticultural fleece until the bulbs are firmly rooted.
Look after your planting and in a few weeks each garlic clove will magically turn into a bulb.
#4. Watering & Caring for your Garlic Bulbs
Water liberally during Spring and early Summer but stop when the bulbs begin to swell. Avoid over watering and only in dry spells where there is less risk of rot affecting the garlic bulb.
During the growing season prevent competition from weeds by keeping the space between the garlic plants weed free. As a tight space between plants and rows a had fork works better than a hoe where you run the risk of damaging the bulb or foliage.
Growing garlic does not need any specialist fertiliser. They’re the original, easy to grow vegetable for the time & money conscious gardener.
#5. Time to Harvest Garlic
Garlic is ready to harvest when the lower leaves turn brown and begin to dry out. At this point the garlic heads should be firm and the cloves swollen. To harvest, carefully loosen the soil with a garden fork and gently lift the bulbs to avoid bruising the bulb.
Cut off the stalks about an inch above the bulb. Allow the garlic to cure in a warm, dry place for two to three weeks before using or storing.
After harvesting your garlic, you can enjoy it fresh or store it for later use. If you plan on storing your garlic, be sure to cure it properly first. Curing helps to improve both the flavor and storage life of garlic.
To cure garlic, simply allow it to sit in a warm, dry place for two to three weeks . Once cured, you can store garlic in a cool, dark place for up to six months.
With proper care and harvesting techniques, you can enjoy fresh garlic all year! Growing your own garlic is a great way to get started in the world of gardening.
With just a little effort, you can have fresh garlic at your fingertips to use in all your favorite recipes. Try growing your own garlic this year and see how easy and rewarding it can be!
Common Pests and Diseases that can affect Garlic.
White Fluffy Fungus
White fluffy fungus can be a sign that your garlic is ready to harvest. This is because the fungus growing on the garlic indicates that the plant’s sugars have begun to convert into alcohols. While this may seem like a bad thing, it’s actually a good indicator that your garlic is maturing and will be ready to harvest soon.
This is a fungus that attacks the Allium family, of which garlic is a member. The fungus will cause the leaves of the plant to develop rust-coloured spots. In some cases, the entire leaf may turn brown and die. If left unchecked, t can kill an entire garlic crop.
The best way to prevent leek rust is to plant resistant varieties of garlic. You can also take measures to control the moisture in your garden, as wet conditions are ideal for the spread of this disease. If you do find rust on your plants, remove and destroy any affected leaves immediately. With proper care, you should be able to keep this problem under control and enjoy a bountiful harvest of delicious garlic cloves!
Onion White rot
Onion white rot is a serious disease that can affect both onion and garlic crops. The disease is caused by the fungus Sclerotium cepivorum, which attacks the roots and bulb of the plant.
Symptoms include white mould on the bulbs and leaves, as well as stunted growth. If left untreated, white rot can kill an entire crop.
There are several ways to prevent white rot from occurring in your garlic crop. One is to rotate your crops so that they’re not planted in the same spot year after year. This will help to keep the fungus from becoming established in one area.
You should also dig up and remove any infected plants as soon as possible so that the fungus doesn’t have a chance to spread. Finally, make sure you’re using clean, sharp tools when you’re handling your garlic. This will help to prevent the spread of the fungus.
By following these tips, you can help to prevent onion white rot from destroying your garlic crop.

The answer is yes! You can grow garlic in a pot, and it is not difficult to do so. Here are some tips to help you succeed:
– Start with a good quality potting mix. Be sure to use one that is well-draining, as garlic does not like wet feet.
– Choose a pot that is at least 12 inches wide and deep.
– Plant garlic cloves in the Autumn or Spring (depending on variety)
– Place the cloves root side down, spacing them about four inches apart.
– Water well after planting, and then keep the soil moist but not soggy throughout the growing season
Do I need Fertiliser for garlic
Providing you applied fertiliser at the time of planting garlic should be ok without any additional fertiliser until harvest time. However, if you didn’t fertilise at planting give your garlic a feed now. A good organic fertiliser will do the trick.
Why are my garlic cloves green?
Green garlic cloves are a sign that the cloves were not planted deep enough and have been getting sunlight on the growing bulb.
Can I use shop bought garlic bulbs?
Whilst it is tempting you should avoid using shop bought garlic for planting. The bulbs you purchase from the supermarket have probably been treated with chemicals to stop them sprouting and can also carry disease.
If you want to be sure of success, buy certified garlic from a reputable gardening supplier.
Do you peel garlic before planting?
No, there is no need to peel the garlic before planting as the peel protects the clove in the first stages of growth.
It is possible to grow garlic indoors?
You can grow garlic indoors but there are a few things you need to take into account.
Garlic needs a lot of sunlight so make sure when growing garlic indoors they get plenty of light. You’ll also need to water your garlic regularly and fertilize it every few weeks. Most gardeners tend to grow indoors for the ‘greens’ produced.
These are great snipped off every few weeks and added to recipes when cooking.
