How to Grow Garlic In 7 Steps
Garlic is easy to grow and is a great crop for beginner gardeners.
With the large variety of garlic available, there is a variety that will be suitable to grow in any region. Garlic can also be grown in raised beds and containers. A little patience is needed when growing garlic because it takes 8-9 months to mature.
But the wait is well worth it to have homegrown garlic in your pantry. Here are the steps to get your garlic bed up and growing.Â
1. Choose the best garlic variety to grow based on where you live.
The first thing you need to do is find the variety or varieties of garlic that will grow best in your region, and what the best time to plant is for the variety you decide.
A chart of the climate zones and the recommended planting times is provided below, as well as a list of garlic varieties to consider. It’s best to plant your garlic in the fall from late September-mid October to allow the garlic to go through a dormant period where it’s exposed to cold temperatures, this process is called vernalization.
If you live in a cold climate, you will want to plant your garlic 3-6 weeks before your area’s first expected hard freeze. Usually Sept-Nov, this will allow the plant to grow a good root system before the ground freezes. For warm climates, you will want to plant your garlic 3-6 weeks before your area’s coldest time. Usually by early December.
2. Prepare the garlic bed.
Next, you will need to prepare your garlic bed. Garlic prefers to grow in full sun in a well drained soil, rich soil.
If you have clay soil, you will want to loosen it up a bit by mixing a 3-inch layer into the soil. This will loosen the soil to improve drainage, but also give the soil some extra nutrients.Â
3. Time to separate and get a little judgmental.
Now that your bed is ready, separate your garlic bulbs and choose the cloves the largest, plumpest firm cloves for planting. Be sure to not damage the papery skin on the cloves(garlic seed). Avoid using the smaller bulbs as these will produce small bulbs.
4. It's planting time!
To plant your garlic, dig a trench that’s 2–4 inches deep. Here’s a good way to know how deep your trenches should be, in warm climates you can dig a 2-inch trench safely and in colder climates you will want to dig a 4-inch trench.
To give your garlic seed a good dose of nutrients to use, put some worm castings under each of the cloves.
Place the clove with the pointy end pointing up. Place the cloves 4-6 inches apart to allow the plant plenty of room to grow. Each of your rows should be 6-9 inches apart.
Cover the trench with soil.
If you happen to live in an area that receives a lot of rain and is humid, you will want to place each clove 6 inches apart and your rows should be 9-12 inches apart. This is to increase the air circulation around the plants and reduce the risk of them developing a common fungal disease called rust.
5. Water the bed mindfully.
Water the bed to help settle the soil, but be sure not to overwater, garlic doesn’t like wet soil, it prefers a moist soil.
After watering, apply a 3-6inch layer of clean straw over the entire bed. In cold climates, stick to using a 6-inch layer of straw to help keep the soil warm, to give your garlic time to get a good root system started before the ground freezes.Â
6. Let's talk soil!
During the fall and winter, the soil only needs to be lightly moist. You can stick a finger into the top 2 inches of soil to test its moisture content and water if it feels dry.
It’s always important to not overwater garlic.
During the cooler moths, the soil will retain more moisture. Using a drip irrigation system for watering garlic, because you always want to avoid watering the leaves, you want the water to go to the roots. This is why the drip irrigation is the best option to keep your garlic happy.
In the spring, you can start watering again. You will want to give deeper, less frequent watering on a consistent basis, usually 2 inches of water once a week, unless the weather is warmer and the soil gets dry.
If you have chosen to grow a hardneck variety (more info on varieties below), you will notice scapes (stiff flowering stalks that grow from the center of the leaves) growing starting late spring to early summer. It’s recommended to cut these scapes off after they have formed one curl, to allow the bulbs to use all the energy to for big cloves.
Don’t throw those scapes away, they are delicious and make a tasty addition to any salad or dish.
7. About nine months later, it's time to harvest.
After waiting 8–9 months, it’s time to find out if it’s time to harvest your garlic. The best way to is to look at the leaves, when 50% of the leaves are green and 50% are brown (the leaves will turn brown from the bottom up).Â
This is the plant’s best sign to tell you it’s ready to go.
It’s a good idea to confirm its readiness, choose a bulb or two and gently digging around the bulb and to feel how big it is and be sure not to damage the papery wrapping around the bulb.
If the bulb is small, pat the soil back around it and give it a few more days and check again.Â
An important thing to note is to not wait until the all the leaves have turned brown. You want to harvest when there are still green leaves, as each green leaf is an indicator for how many layers of papery wrapping are on the bulb.
It’s also recommended to stop watering a week before you plan to harvest, this will allow the soil to dry a little, which will make it easier to remove the bulbs.
After you harvest your garlic bulbs, give them a gentle brush to remove any excess dirt that remains on the bulb. Be sure to never wash your bulbs and that the wrappings stay intact.
Some wrapping will fall off and that should remove most of the remaining dirt and the layers underneath will be clean.
Storing Your Garlic Safely
Never Refrigerate Your Bulbs
For any bulbs you’ll be using right away, you can use them fresh from the garden. Just cut away the leaves and trim the roots, then place your garlic bulbs in a wire basket and place in a dark, room temperature, dry area with good air flow.
A cupboard or pantry will work fine.
You never want to refrigerate your garlic bulbs, you should use your fresh bulbs within 3 weeks of harvesting.
Curing Garlic For Long Term Storage
To store your garlic for a longer time, you will need to cure it, which basically is letting it dry.
Curing will take 2 weeks to two months, if you’re in a dry/warm climate your bulbs should be cured in 2-3Â weeks, and if you’re in a humid/wet climate it could take 2 months for your bulbs to cure. Once cured and properly stored, your garlic can store your garlic for several months.
You can tell when garlic is cured by checking the roots and leaves, if they are completely dry and stiff, they are cured.
To store your cured garlic, cut the leaves away and trim the roots, so they are 1/4-1/2 inch long using pruning shears then keep in a room temperature, dry area like a pantry or cupboard.
Always store your garlic in a breathable container, to allow the air to circulate around the bulbs. A wire or woven basket, the bags you get your onions or potatoes in, will work great.
You can even put your old pantyhose to use to store your bulbs, just place a bulb in, then tie a knot and place another bulb and tie a knot and continue until you fill the hose. Hang in your pantry or cupboard.
To remove a bulb, just cut under the next knot (just be sure too not cut into the knot above).
When using your stored garlic, be sure to save some of the largest bulbs. You’ll use these bulbs to start your garlic bed in the fall.
When using your stored garlic, be sure to save some of the largest bulbs. You’ll use these bulbs to start your garlic bed in the fall.
Freezing Garlic
You can also store your garlic by freezing it. You can choose to peel and freeze individual bulbs, or you can freeze a variety of chopped, minced and sliced cloves to have ready to go when needed. For individual cloves, place them in a freezer bag or container and spread them out so that they stay separate, after they have frozen, just pick out the amount you require.
When freezing the chopped, minced or sliced cloves, you can either place them in a freezer bag or container and spread it into a thin layer to freeze uniformly. This makes it easier to break off a chunk for cooking.
Alternatively, you can spoon the garlic into ice cube trays and freeze them. Once completely frozen, remove the cubes and put them into a container or freezer bag.
