When and How to Harvest Garlic?

THIS POST MAY CONTAIN AFFILIATE LINKS. PLEASE READ MY DISCLOSURE FOR MORE INFO.

Last September or October or November, you planted garlic cloves and watched them grow steadily and patiently through winter and summer. It’s now summer, and you feel the time is ripe for harvesting – and you may be right.

Unlike other vegetables you might have planted in spring and got your harvest in fall, garlic needs between 7 and 9 months to mature, depending on what type you grew. And if you are reading this, you must have gotten the planting right. But in case you feel you could’ve done something better, read this garlic planting guide.

How To Plant Garlic

Growing garlic is easy as long as you get the timing right to plant garlic and nurture healthy crops and when harvest garlic. With garlic, fall planting is highly recommended for two main reasons:

  • Fall-planted garlic allows the bulbs to establish strong root systems before the ground freezes.
  • It also allows the bulbs to produce green leaves by early spring so that they’ll be ready to sprout as soon as the snow melts in the spring.

Fall plantings should be ready for harvest in the mid to late summer. Here is a simple guide to planting garlic

Choosing And Preparing The Planting Site

Choose a site that receives 6-8 hours of direct sunlight per day. Preparing your garlic bed.  Both soft neck varieties and hard neck garlic varieties prefer rich, well-drained soil. Remove any weeds and mix in a blend of compost and organic fertilizer into your raised beds. To grow strong and healthy garlic, heavily mulch your raised beds, especially when working with heavy soil.

Planting Garlic Cloves

Plant garlic cloves from a local grocery nursery or order from a garlic seed company. Do not plant cloves bought from the grocery store. Store-bought garlic cloves may be unsuitable for your area.

Break apart the bulb into individual cloves. Select the largest and healthiest ones for planting. Place the cloves of garlic in the ground at about 2 inches deep with the tip facing up. Position the cloves 2-4 inches apart. Plant garlic in rows spaced 10-14 inches apart.

Growing Garlic

When growing garlic, make sure to mulch it heavily to allow proper overwintering. If you are not growing soft neck varieties, watch out for the scapes. The scape is a flowering stalk that shoots from hard neck garlic varieties. You need to cut them off as soon as they emerge to increase bulb size. Finally, side-dress your garlic plants in early spring with nitrogen-heavy fertilizer like blood meal, compost manure, or store-bought fertilizer.

Fertilize again in response to the lengthening daylight, just as the bulbs start to swell. Make sure your garlic beds remain weed-free and water every 3-5 days as you wait to harvest garlic.  Harvest from fall plantings is often between late June to August, depending on when you planted, the climate in your area, and the type of garlic you grew.

How To Know When Your Garlic Is Ready For Harvest

As a serious farmer, you cannot afford to harvest garlic too late or too early. Harvesting garlic too early can yield tiny bulbs, whereas waiting to harvest too late in the season can lead to rotten or overripe bulbs.

Garlic harvests should start when the foliage starts to turn brown. Harvest garlic when the tops leaves begin to wither but before all the leaves have died.

Waiting to harvest garlic after all the leaves have died predisposes your bulbs to rot. On the flip side, garlic matures when some of its leaves are still green, and it doesn’t push itself above the soil, making it even harder to know. Luckily, there’s a trick you can use to know the right time, and this is by looking at the number of leaves left on the garlic plant.

Remember that every garlic leaf you see above the ground represents a protective layer of ‘paper’ that’s wrapped around the garlic bulb. So, for instance, if a garlic plant has ten leaves, it means ten layers are wrapping the bulb.

While garlic plants grow a varying number of leaves, a sure-fire way of knowing they are harvest-ready is when half the leaves are green and half are brown and dead. Then, usually, the leaves start drying from the bottom.

Be careful not to wait for all the garlic plant leaves to die before you harvest. If you do, it means the protective ‘paper’ around the bulb is rotting, and the cloves are more exposed to soil elements, including worms. As a result, your garlic bulbs will not store well.

If you planted hard neck garlic, there’s another trick you can use to tell when it’s time to harvest.  About week 4 or 6 before maturing, the garlic plant will produce scapes that you can harvest and use in your recipes. After this harvest, count four weeks and then start checking the bulb size.

Important note: Even when the leaves start dying, you should continue watering the garlic plants until about 50% of the leaves are dead. At this point, don’t water them for a week to give the soil time to dry and keep the roots from rotting. Also, it’ll be easier to harvest when the soil is crumbly and loose than when it’s wet and compact.

Harvesting Garlic

Before you start your garlic harvest, the first thing you should do is to sample. Lift a bulb to see if it is ready for harvest.

The First Step Is Doing A Pre-Check

You do this by lightly digging the soil around a garlic bulb with a garden fork. (it could be one or a couple of random bulbs in your garden). As you do this, make sure you don’t damage the cloves or wrappers. Also, you should do it without removing it from the ground.

If the bulb appears too small for your liking, you should return the soil, give it a light pat and wait a little longer. You can come back after a few days to confirm the size. And if this time it’s big enough, the wrappers are tight, and cloves are well-formed, they are ready for harvest.

At this stage, you should loosen the soil around the bulb using a trowel. After, pull the garlic plant out of the ground from the base of the stem. Next, you can brush off the excess dirt that’s loosely attached.

You might be tempted to get your garlic bulbs as clean as those in the grocery store, but you resist the urge. Washing garlic bulbs or removing the wrappers after a harvest can compromise how well the bulbs store.

Why? Well, when you wash garlic, the bulbs retain the moisture, which can cause fungal infections. This process also takes unnecessary time while you should be striving for efficiency in your process.

Moreover, garlic bulbs naturally clean themselves. You see, dirt only sticks to the outermost layer of the protective layer. This layer usually shreds and falls off naturally to reveal a cleaner wrapping layer.

Using And Storing Garlic

If you intend to eat the garlic immediately, you should trim the roots and leaves so that they are tidy when you bring them to your kitchen. It would be best if you stored garlic bulbs at room temperature in a dark and dry spot with lots of air circulation. Putting them in a wire basket in the cupboard or pantry will work just fine.

Do not store the bulbs in a cold room or your refrigerator. Moisture and light are garlic’s enemies. Instead of increasing its storage life, the garlic will get moldy or start sprouting.  To last longer, store garlic in a cool place with ample air circulation.

You can use the garlic in 3 weeks or between 7 and 10 days after breaking a garlic head. When harvesting, keep an eye out for garlic bulbs that are cosmetically damaged but are edible. Use these first as they’ll not store well even with the right conditions.

If you’d like to prep garlic for longer storage, leave the roots and leaves intact and follow the instructions in this guide’s ‘How to Cure and Store Garlic’ section.

When Garlic Matures

The golden rule of thumb is that Turban and Asiatic garlic types mature earlier (in some climates, this happens in May) while Silverskin garlic types mature later (usually in July or August).

Often, there are between 6 and 8-week differences between the early and late harvest times. So, if you are going for early maturing garlic types, be aware that they are smaller than those that take longer to mature.

Here’s a quick example to help paint a better picture of the harvest times. In October, when you plant Siciliano and Ajo Rojo in Southern California, you will harvest the garlic bulbs two weeks apart. The harvest season may be in late May or early June for those in warmer climates. However, if your region is colder, this could be in late July or early August.

Bear in mind that the actual time you’ll harvest depends on your area’s soil conditions and the prevailing weather. So if you grow Asiatic garlic this time and harvest in late May, it doesn’t mean this will be the case in the next season.

Because there aren’t any specified harvesting times, we started by giving you tricks to know when your garlic is ready for harvest. So now, let’s proceed to cure and storage of garlic.

How To Cure And Store Garlic

Apart from harvesting, it’s also crucial to learn how to cure and preserve garlic.

Now, after harvesting, you just cannot tuck the cloves away for the next planting season. Instead, you have to cure them. Using is a process of removing moisture to improve the shelf life of the bulbs. Moreover, curing calms down the flavors and makes them more interesting and palatable.

With that said, how you store your garlic largely depends on how you intend to use it. For example, you could decide to braid the leaves and hang them from a rafter, freeze or dehydrate them.

Below is a complete guide of everything you need to know.

Curing

While you can use the bulbs that you’ve just harvested in your recipes, the flavor and odor will be quite pungent. So if that’s not something you can stomach, you should cure garlic bulbs first.

Curing is done immediately after you harvest garlic from your garden. This is done to get rid of excess moisture to improve the storage life of garlic. In the process, the flavors improve as well. Consequently, you can comfortably eat garlic raw or cooked.

To start the curing process, layer your garlic plants on a screen or tray. Ensure the roots, leaves, and stalks are intact so that all energies are concentrated on drying the bulb.

Place your tray in a warm and dry spot that’s shaded from direct sunlight but has enough air circulation. You can leave them here for a couple of weeks but make sure to come back after every 24 hours to turn them. How long this process takes depends on how much moisture is in the plant tissue. When every green leaf has turned brown, and the stems aren’t plaint, you can consider the bulbs successfully cured.

Prepping And Cleaning The Bulbs

After curing, you need to clean the bulbs before storage. The process is easy but can be time-consuming because of the accuracy required.

With a pair of scissors, you should trim the roots very close to the ends of every bulb. And with a soft brush, wipe away the remaining dirt on the bulb. Be gentle as you do this to avoid any damage to the bulb wrappers.

Speaking of damage, this is a great time to remove damaged or smaller bulbs from the group. Though they may be intact right now, they’ll not last for a long time.  As such, they should be the first to be used.

It would be best to trim their stem between 3 and 6 inches from the top for hard neck garlic varieties. Make sure you leave enough of the stem to wick away moisture that might have remained from the curing process. This stem also makes opening the bulb simpler.  And if you want to hang the bulbs, the stem will come in handy.

The above is true for soft neck garlic. But in their case, the braiding process should be completed before curing.

If you are content with the results from the variety you planted, you can save some for the next planting season. Pick the plumpest, largest, and best-looking bulbs to use as seed stock. This way, their genes will pass down to the next generation yielding bigger and even better bulbs.

How To Store Garlic

Even after curing your garlic, you have proper storage. The spot you choose should be dark, dry, have good air circulation, and be between 55 and 60 degrees Fahrenheit.

As we mentioned, you shouldn’t store your bulbs in a refrigerator. The combination of moisture and light creates a conducive environment for mold growth and for garlic to sprout.

You can store cured bulbs in a wire basket, open wicker, egg cartons, horticultural boxes, an open paper bag, or netting.  Alternatively, you can prefer the below storage methods.

Dehydrating For Salts And Powder

Dehydrating garlic gives you the longest storage.  Any halved pieces can be packed as is or ground for flavoring salt and garlic powder.

Dried pieces, flavored salts, and powder can be used in many different flavoring ingredients and foods like casseroles, stir-fries marinades, dry rubs, grilled meats, roasted veggies, soups, sauces, stews, or one-pot meals.

Below Is What You Can Do

Peel the garlic cloves and cut them lengthwise in half. Layer them on drying trays, ensuring the cut sides face up.

  • Dry the cuts at 140 degrees Fahrenheit for two hours and then turn them for a quick finish at 130 degrees Fahrenheit. When completely dry, the garlic pieces will be crisp.
  • Remove them from the drying trays and put them on a wire rack to cool before you package them.
  • Pack the garlic halves in glass jars with air-tight lids and store them in a dry and cool cupboard.

Tips: if you usually have a surplus harvest, you can purchase a dehydrator. It is economical and can dry other foods, including vegetables, herbs, fruits, and berries.

For ground garlic, put the dry garlic in a mortar and grind them into powder. If you are working with a lot of garlic cloves, this process can be tedious and time-consuming. To save some time, consider using a spice mill or a coffee grinder.

From powdered garlic, it’s easy to make garlic salt. You simply add sea salt to the powder in a 4:1 ratio and stir until it blends completely.

Note: the flavored salt, powder, and dehydrated halves should be stored in air-tight containers and placed in a cool and dry spot away from direct sunlight. In the right conditions, they can last for four years.

Freezing

Freezing is another great option to consider. However, it’s important to note that the texture and color of garlic might change after freezing. But on the bright side, the cloves still pack many flavors and can be used in making soups, stews, sauces, dressings,  stir-fries, and casseroles.

Below are some ways you can freeze garlic:

Peel and cut the cloves into pieces. Put the tiny pieces of garlic into a freezer bag and push it to the bottom before rolling it into a stick and sealing it. When it’s solid, you can chop, grate or break it as much as you need.

Freeze entire bulbs with the paper tunics and then pack them into containers or freezer bags. Later you can remove cloves as you need them.

Peel and blend your cloves in a blender. Add some olive oil to the garlic in the ratio of 1:1 and then freeze the mixture in small ice cube trays. When ready, transfer the garlic cubes to containers or freezer bags for storage. You can use each cube as you need it. In this state, the garlic can last for 12 months in your freezer.

Flavored oils

If you decide to go down this route, you should be cautious.

To store your garlic in oils, you should peel the cloves, dip them in oil, and store them for a couple of months. After that, even though it’s in a refrigerator, chopped and whole cloves you store in oil should be discarded after four days to prevent the formation of toxins. And those that are left at room temperature should be poured out after only 2 hours.

How do toxins form in these conditions?

Garlic is a low-acid vegetable that has a pH between 5.3 and 6.3. When you add it to oil, you create the perfect conditions for the growth of Clostridium botulinum. This is the bacteria responsible for botulism.

To ensure you are safe, you should track the oil blends closely. Then, right after preparation, you should add the preparation date plus the discard date. And if you are unsure of the oil, discard it.

Bundling And Hanging

This process is easy and super effective. Hanging garlic from rafters or hooks provides ample air circulation for the bulbs, keeps them dormant and dry.

You can tie hard neck bulbs into bundles of six or twelve. With soft neck garlic, you should braid them immediately after harvesting them and before curing. At this stage, the leaves will still be green which will make braiding easier. To do it efficiently:

  • Bundle 3 bulbs together where the stem meets the bulb with a piece of twine and then arrange them on a flat surface with their stems facing down
  • You’ll have three plant stems – one on the right, another at the center, and another on the left
  • Add the fourth bulb at the center and lay its stem beside the center stem
  • Cross the stem on the right over the center stems like you would when braiding hair
  • Add another bulb to the center and lay its stem at the center
  • This time, cross the left stem over the center stems
  • Keep repeating this process until it’s complete
  • When you finish adding bulbs, braid the remaining stems to finish the braid
  • Trim any loose tips into hanging loops

Like other storage alternatives, store the braided garlic in a dry and cool location with sufficient air circulation.

Pickling In Vinegar, Wine, Or Brine

This is another effective way to improve your scape’s shelf life while maintaining enhancing its flavor.  The resulting nutty and mild taste is perfect for antipasto platters or salads.

To pickle garlic, add peeled and cleaned cloves into a sterilized jar and then process it in a hot water bath for some time.  As we pointed out earlier, garlic is considered a low-acid vegetable. It’s therefore important that you use a pickling recipe with high acid to prevent bacteria growth. If you are unsure of the acidity, store the canned pickles in a refrigerator.

To keep track of everything, you should add preparation and discard dates to the jars.

Alternatively, you could make a refrigerator pickled with vinegar or wine. All you need to do is add cleaned and peeled cloves into a jar and then top up with dry white or red wine or vinegar. To improve the crunch, you can add some bay leaves. If you want, you can add some pickling spices like celery seed, cumin, chili flakes, peppercorns, mustard seed, berries, and bay leaves.

Refrigerator pickles stores for four months in the fridge if they remain submerged in your liquid of choice.

Saving Some Garlic Seed

Garlic cloves can be saved as seeds for the next year’s crop. To achieve this, pick the healthiest looking – the most mature and plump bulbs and store them in open bags or baskets in a well-aerated spot with moderate humidity until planting season.

The Bottom Line

The fact that you got a good harvest is good news, and you should be happy about it. In this piece, you’ve learned when to harvest and how to harvest. We’ve outlined some of the do’s and don’ts when harvesting and have even gone deeper to highlight some of the ways you can ensure your garlic lasts long.

Being your first harvest, you might be strict about doing things and forget to have fun with the process. But provided you get the conditions right for harvest and storage, everything in between is easy, and you can have fun. Finally, remember to store some garlic for your next planting season.  This is a good step towards being self-sufficient.

People Also Ask

What Happens When I Pull My Garlic Too Early?

Harvesting your garlic crop too early will lead to a poor garlic harvest. The chances are high that the bulbs will yield tiny cloves that aren’t fully developed yet. In addition, the protective papers around the bulb may be fewer and too thin, meaning they’ll disintegrate faster, leaving the bulb susceptible to damage and reducing the store life.

What Happens If I Leave My Garlic Too Long In The Ground?

If you leave the garlic for too long, then the garlic bulbs will over-ripen. The individual cloves might even start to separate and form shoots. Though in this form, the cloves are still edible, their storage is significantly reduced. In such cases, you might have to use the garlic immediately.

Should I Let The Garlic Plant Flower?

Well, this depends on what you want. Hardneck varieties produce flower stalks called garlic scapes in early spring. If your goal is to harvest garlic seeds, then you should let the scapes grow. If, however,  your goal is to grow bigger bulbs,  you should consider cutting the garlic scapes.

Otherwise, letting the garlic scapes blossom causes the plant to divert its energies to flowering, stunting the growth of your bulbs. The best part is that fresh garlic scapes are edible. They can be eaten raw or cooked.  If you don’t trim these, they’ll blossom.

Can I Use The Garlic Right After Harvesting?

Yes, you can. Freshly harvested garlic can be consumed when cooked or raw. You can also eat it before curing it. It’s good practice to separate your harvest into groups that you can consume in about three weeks. Any garlic bulbs that will be used later than this should be cured.

When To Harvest Your Spring Garlic

Spring garlic is also known as baby garlic or green garlic. This is garlic that you plant in the fall but you’d like to harvest before maturity. Green garlic bulbs aren’t separate yet. However, they are rich in flavor, just like scallion leaves.  You can harvest green garlic in early spring when the leaves are tender and green. Some farmers grow green garlic as their primary crop, while others use the technique to thin out a densely planted garden.

How Many Garlic Bulbs Do You Get From One Plant?

Each garlic plant yields one head of garlic. Therefore, every bulb can have between 5 and 10 cloves depending on the type of garlic.

Why Is My Garlic So Small?

Extreme weather conditions can stunt garlic plant growth, causing the bulb to be underdeveloped and small. Also, pests can cause stunting. You can also get small bulbs if you harvest your plants too early.
