A Comprehensive Guide to Growing and Harvesting Garlic in Your Garden

Are you eager to explore the world of homegrown garlic but feeling uncertain about where to begin? The good news is that growing garlic is not only straightforward but also an enjoyable gardening experience. In this comprehensive guide, we will walk you through every step, from selecting the perfect garlic variety to planting, nurturing, and eventually harvesting your aromatic bulbs. So, let's dive deep into the wonderful world of garlic cultivation!

Planting Garlic: From Store to Garden

The Pitfalls of Store-Bought Garlic

Store-bought garlic can be a convenient option, but it comes with some potential drawbacks. Many store-bought garlic bulbs are treated with sprouting inhibitors to extend their shelf life. Unfortunately, these inhibitors can hinder the germination of cloves when planted. Additionally, store garlic may have been grown in a different climate, making it less adaptable to your local conditions.

Opting for Fresh Organic Garlic or Seed Garlic

To ensure a successful garlic crop, it's highly recommended to seek out fresh organic garlic or organic seed garlic for planting. These garlic varieties are untreated, more likely to sprout, and better suited to your garden's environment. By making this choice, you set a strong foundation for your garlic-growing journey.

Garlic's Growth Timeline

Timing for Garlic Scapes and Bulbs

Garlic follows a fascinating seasonal growth pattern. When you plant garlic in the fall, you can look forward to the emergence of green garlic scapes (especially in hardneck varieties) in late spring to early summer. The garlic bulbs themselves will be ready for harvesting in the heart of summer, typically from mid to late summer.

Choosing the Right Garlic for Your Garden

Local Garlic Varieties vs. Commercial Options

One of the secrets to successful garlic cultivation is selecting garlic varieties that are well-suited to your local climate. Local garlic varieties often thrive because they have adapted to the specific conditions of your region. If you have access to garlic from a local grower or friend, consider it a golden opportunity. If not, don't fret; you can explore different garlic varieties online or at your local garden center.

Exploring Garlic Varieties

Hardneck Garlic

Hardneck garlic, scientifically known as Allium sativum var. ophioscorodon, is distinguished by its rigid stem, surrounded by a ring of cloves. These varieties are typically known for their hardiness and are often favored in regions with colder winters. They are best suited for USDA hardiness zones 3-6, with some varieties extending to zone 3-8.

Softneck Garlic

Softneck garlic, or Allium sativum var. sativum, is characterized by a smaller, flexible central stem, often encircled by layers of cloves. You may recognize these as the types of garlic that are often braided together and sold in grocery stores. While softneck varieties tend to produce larger yields, they may be somewhat less cold-hardy. They are typically suitable for USDA zones 3-9.

Elephant Garlic

Interestingly, elephant garlic (Allium ampeloprasum) is not technically garlic but rather a type of leek. It boasts a few large cloves and a milder flavor that appeals to some and not to others. While it's not a true garlic, it can still be a fun addition to your garden.

Planting Garlic: A Step-by-Step Guide

Preparing the Planting Bed

Before planting your garlic cloves, it's essential to prepare a well-drained planting bed. Ensure that the soil is loose, well-aerated, and free from weeds. Consider adding compost or well-rotted manure (avoid fresh manure) to enrich the soil.

Breaking Garlic Bulbs into Cloves

Separate the garlic bulbs into individual cloves, but leave the papery covering on each clove intact. Each clove will eventually give rise to a whole new garlic bulb.

Optimal Sunlight and Soil Conditions

Garlic thrives in full sun, so choose a planting location that receives at least 5 hours of direct sunlight per day. Additionally, garlic prefers soil with a neutral to slightly acidic pH level, ideally between 6-7.

Planting Depth and Spacing

Plant garlic cloves with their tips facing upward, positioning them about six inches apart and burying them 2-3 inches deep in the soil. Ensure that the soil remains consistently moist but not overly saturated.

Planting Techniques

If your soil is loose and friable, you can easily plant garlic cloves by gently pressing them into the soil with your fingers. However, if your soil is heavier or compacted, consider digging trenches across the width of the bed and placing individual cloves along the rows. Cover the cloves with soil and gently pack it down to ensure good soil-to-clove contact.

Mulching for Garlic Protection

The Importance of Mulching

To protect your garlic over the winter months, apply a thick layer of mulch, such as straw or leaves, before the ground freezes. Mulching helps insulate the bulbs, preventing them from being pushed out of the ground by frost heaves.

Preparing Garlic for Winter

The mulch serves as a protective blanket during winter, shielding your garlic from harsh temperature fluctuations. This layer can also help regulate soil moisture.

Mulch Removal in Spring

As spring arrives, you can pull back some of the mulch to encourage the soil to warm up, promoting garlic growth. Additionally, consider adding a layer of compost at this stage to provide nutrients to your growing plants. You'll typically notice little green garlic shoots emerging around the same time as other spring bulbs.

Harvesting Garlic

When to Harvest Garlic Scapes

Hardneck garlic varieties will produce flower stalks called scapes in late spring. To encourage larger bulb growth, it's advisable to remove these scapes. Southern Exposure Seed Exchange recommends snipping the scapes at the junction of the highest leaf as soon as they have uncoiled from their 360° turn. Delaying scape removal can lead to a reduction in bulb yield.

Maximizing Bulb Size

From personal experience, we've observed that allowing scapes to remain on the plant after the recommended stage can result in smaller bulbs at harvest time. Therefore, timely removal is key to ensuring a bountiful garlic crop.

Harvesting Garlic Bulbs

Garlic bulbs are ready for harvest in late summer when you notice the lower leaves turning yellow and the tops beginning to tip over. Waiting until the tops are entirely brown is not advisable, as it can lead to bulbs with thin papery coverings that may not store well.

Be mindful of your local weather conditions, as fall rains after a dry summer can cause bulbs to rot if left in the ground for too long. Harvest garlic bulbs by gently loosening the soil with a garden fork and carefully lifting them from the ground. Avoid pulling on the stems, as this can leave bulbs behind in the soil.

Curing Garlic Bulbs

Importance of Curing

Curing is a crucial step in the garlic cultivation process, as it prepares the bulbs for long-term storage. The curing process involves removing excess moisture and toughening the outer skin of the garlic bulb.

Proper Curing Conditions

After harvesting, select garlic bulbs that are free from damage, soft spots, or insects. Spread these bulbs in a single layer in a dry area with good air circulation. While the stems can overlap, avoid stacking the bulbs on top of each other. Many gardeners choose to place their garlic in a greenhouse, garage, outbuilding, or covered porch. Avoid exposing the bulbs to excessive direct sunlight, as this can cause sunscald.

Curing typically occurs in temperatures ranging from 70°F to 80°F, ideally with reduced humidity. These conditions promote the drying of garlic skins and necks.

Storing Cured Garlic

Once the garlic bulbs have sufficiently dried during the curing process, brush off any loose dirt and outer layers of skin. Trim the tops and roots close to the bulb's base. Damaged bulbs should be set aside for immediate use. To store garlic bulbs for the long term, place them in a bin or container in a cool, dry location that receives no direct sunlight. Alternatively, if you have softneck garlic varieties, you can braid them and hang them up for display.

Avoid storing garlic in areas with high humidity, as moisture can lead to rot and mold. Additionally, ensure that the storage temperature stays between 34°F to 40°F, preventing freezing, as extreme cold can damage the bulbs. Most sources recommend that properly cured garlic bulbs can remain viable for 3 to 6 months.


Growing garlic in your garden is a gratifying endeavor that rewards you with aromatic, pesticide-free bulbs. By following the detailed steps outlined in this guide, from selecting the right garlic to proper planting, nurturing, harvesting, and curing, you're on your way to becoming a successful garlic gardener. Embrace this journey with enthusiasm, and soon you'll be enjoying your own homegrown garlic in your favorite culinary creations. Happy gardening!
