What is Garlic?

What is Garlic

Garlic (Allium sativum) is a bulbous plant closely related to onions, shallots, and leeks. It is native to Central Asia and northeastern Iran and has been used for both culinary and medicinal purposes for thousands of years. Each garlic bulb consists of numerous cloves, each enclosed in a paper-like skin.

Garlic Softneck Varieties

Softneck garlic, known for its flexible stalk, is the type most commonly found in supermarkets. It generally produces more cloves per bulb than hardneck varieties. Popular softneck varieties include ‘Silverskin’ and ‘Artichoke’, known for their mild flavor and excellent storage properties.

Garlic Hardneck Varieties

Hardneck garlic features a rigid central stalk and produces fewer but larger cloves than softneck types. They are more flavorful and have a variety of tastes and heat levels. Notable hardneck varieties include ‘Rocambole’, ‘Porcelain’, and ‘Purple Stripe’, each offering distinct flavors and slightly different growing needs.

How to Plant Garlic

Garlic is best planted in the fall, about 4-6 weeks before the ground freezes. Plant cloves pointy-end up, about two inches deep and 4-6 inches apart in well-drained soil. Ensure your garden bed receives plenty of sunlight.

Step 1: Choose the Right Time

Garlic is typically planted in the fall, about 4-6 weeks before the first hard frost. This timing allows the garlic to establish roots before the ground freezes but prevents significant top growth, which can be damaged by winter weather. In milder climates, planting can also be done in early spring as soon as the soil is workable.

Step 2: Select Quality Garlic Bulbs

Choose high-quality, disease-free garlic bulbs from a reputable nursery or garden center. Avoid using garlic from grocery stores as it may have been treated to inhibit sprouting. Consider the variety that best suits your climate and taste preferences, whether it’s a robust hardneck or a milder softneck.

Step 3: Prepare the Soil

Garlic prefers well-drained, fertile soil with a pH of 6.0 to 7.5. Prepare your garden bed by loosening the soil to a depth of about 12 inches and mixing in plenty of organic matter such as compost or well-rotted manure. This will improve soil structure, fertility, and drainage.

Step 4: Break Bulbs into Cloves

Carefully break the garlic bulb into individual cloves shortly before planting. Each clove will grow into a new garlic bulb. Leave the papery husk on each clove as it helps protect the clove and promotes healthy growth.

Step 5: Plant the Cloves

Plant garlic cloves pointed-end up, as the sprout will emerge from the pointed tip. Plant the cloves about 2 inches deep and space them 4-6 inches apart in rows that are 12-18 inches apart. This spacing allows for adequate air circulation and room for the bulbs to develop.

Step 6: Water Your Planting

After planting, water the bed well to settle the soil around the cloves. This initial watering helps initiate root development but be careful not to overwater, as garlic does not grow well in excessively wet soil.

Step 7: Mulch the Bed

Apply a layer of organic mulch, such as straw or leaves, about 2-4 inches thick. Mulch helps maintain soil moisture, suppresses weeds, and provides insulation against severe cold in winter climates.

Step 8: Winter Care

In colder regions, ensure the garlic bed is well-insulated with mulch to protect it from freezing temperatures. Garlic requires little maintenance over the winter, but it’s important to ensure that the bed does not become waterlogged.

Step 9: Spring Maintenance

As the weather warms in spring, begin to reduce the layer of mulch to allow the soil to warm. Keep an eye on moisture levels, particularly as the weather turns drier; garlic needs an inch of water per week, whether from rainfall or irrigation.

Step 10: Fertilize (Optional)

In early spring, consider applying a nitrogen-rich fertilizer to encourage good leaf growth, which is essential for bulb development. However, cease fertilizing by May as you want to encourage the plant to start focusing energy on bulb growth rather than leaf production.

By following these steps, you’ll give your garlic the best start possible, leading to a successful harvest of flavorful bulbs that can enhance your cooking and provide health benefits.

How to Plant Garlic

If you’re too late with planting your garlic, you can try soaking it in water until they root and plant them outside later. Check out the video below on how we did it.

Growing Garlic at Home

Garlic needs cool temperatures during the initial growth phase and requires minimal space, making it excellent for home gardens. It prefers loose, fertile soil with plenty of organic matter. Regular weeding and mulching help retain moisture and suppress weeds.

Growing garlic at home is a rewarding experience and relatively simple if you follow these clear steps. Here’s how to nurture your garlic from planting to mature bulbs ready for harvest:

Step 1: Choose the Right Location

Select a spot in your garden that receives full sunlight for at least 6 hours a day. Garlic thrives in areas with good air circulation and full exposure to sunlight.

Step 2: Prepare the Soil

Garlic grows best in loose, fertile soil. Loosen the soil to a depth of about 12 inches and mix in a generous amount of organic compost or aged manure to improve fertility and drainage. Ensure the soil has a pH between 6.0 and 7.5 for optimal growth.

Step 3: Plant at the Right Time

In most climates, garlic is planted in the fall, about 4-6 weeks before the ground freezes. This timing allows the garlic to establish roots without producing too much top growth before winter.

Step 4: Plant the Garlic Cloves

Separate the garlic bulbs into individual cloves just before planting. Plant the cloves pointed end up, 2 inches deep and 4-6 inches apart, in rows spaced 12-18 inches apart.

Step 5: Water After Planting

Water the soil gently but thoroughly after planting to settle the soil around the cloves and initiate root growth. Avoid overwatering, as garlic does not grow well in waterlogged soil.

Step 6: Mulch Your Garlic

Apply a 2-4 inch layer of organic mulch, such as straw or shredded leaves, over the planting area. Mulch helps maintain soil moisture, regulates soil temperature, and suppresses weed growth.

Step 7: Maintain and Monitor

Keep an eye on your garlic throughout the growing season. Remove weeds as they appear to prevent them from competing with the garlic for nutrients. Water the plants when the soil feels dry to the touch but be cautious of overwatering, especially as the bulbs begin to form.

Step 8: Fertilize in Early Spring

Apply a balanced, slow-release fertilizer early in the spring as the garlic resumes active growth. This will provide a boost of nutrients to support leaf and bulb development. Stop fertilizing once the garlic begins to form bulbs around May.

Step 9: Watch for Pests and Diseases

Regularly inspect your garlic for signs of pests or disease. Common issues include fungal diseases, which can be minimized by ensuring proper spacing and air circulation around your plants.

Step 10: Prepare for Harvest

As summer approaches, start monitoring your garlic for signs of maturity, such as the yellowing and dying back of lower leaves. Reduce watering to allow the bulbs to firm up before harvest.

By following these steps, you will be well on your way to successfully growing robust, flavorful garlic in your home garden.

How to Care for Garlic

Water garlic plants deeply but infrequently, as the bulbs develop best in slightly dry conditions. Avoid overwatering to prevent rot. Fertilize with a high-nitrogen source at planting and switch to a phosphorus-rich fertilizer just before bulb development.

Proper care is essential for cultivating healthy garlic plants. Start by watering your garlic deeply but infrequently; the soil should be moist but not waterlogged. This watering pattern encourages the roots to grow deeper, searching for moisture, and helps prevent fungal diseases that thrive in wet conditions. Initially, apply a high-nitrogen fertilizer to promote strong leaf and root growth. As the growing season progresses and the bulbs begin to form, switch to a phosphorus-rich fertilizer to support robust bulb development. Regularly check for and remove weeds, which compete with garlic for nutrients. Be vigilant about pests and diseases, and apply organic preventive measures if necessary, such as using neem oil for pests or improving soil drainage to fight off fungal infections.

How to Harvest Garlic

Garlic is ready to harvest when the lower leaves start to brown and die back, typically in mid to late summer. Use a fork to gently lift the bulbs to avoid damaging them. Shake off any excess soil and let them dry.

Garlic bulbs are typically ready for harvest in mid to late summer, signalled when several of the lower leaves turn brown while the upper leaves remain green. Harvesting at the right time is crucial for ensuring the bulbs are mature and suitable for long-term storage. Gently loosen the soil around each plant with a fork, taking care not to puncture the bulbs. Lift the garlic bulbs out of the soil, brush off any loose dirt, and be careful not to remove the papery husk around the bulbs as it protects them during storage. Allow the garlic to dry in a cool, shaded area with good air circulation for a few days to toughen the outer layers, which facilitates storage.

How to Prepare and Use Garlic

Garlic can be used raw or cooked in a multitude of dishes to add flavor. To prepare, separate the cloves and peel off the skin. Garlic can be minced, sliced, or used whole, depending on the recipe.

Garlic is a versatile ingredient that adds depth and flavor to dishes, whether used raw or cooked. To prepare garlic for cooking, separate the desired number of cloves from the bulb and peel off the outer layers. You can mince, slice, or leave the cloves whole according to your recipe’s requirements. Raw garlic offers a sharp, pungent flavor, ideal for dressings and sauces. Cooking garlic mellows its intensity and brings out a sweeter, more nuanced flavor, making it suitable for a wide range of culinary applications from sautés to roasts.

How to Store Garlic

Cure garlic bulbs in a dry, shaded area with good air circulation for a few weeks after harvesting. Once dried, trim the roots and stalks and store in a cool, dry place. Properly stored garlic can last for several months.

After harvesting and drying your garlic, it’s important to cure it properly to extend its shelf life. Hang the garlic in bunches or spread it out in a single layer in a dry, well-ventilated area away from direct sunlight. This curing process should last for a few weeks until the roots have dried and the outer skin is papery. Once cured, trim off any dirt-clad roots and the hardneck stalks if you’ve grown hardneck varieties. Store the cured garlic in a mesh bag or loosely woven basket in a cool, dry place such as a pantry or cellar. Properly cured garlic can last up to several months, depending on the variety and storage conditions. To maintain freshness, avoid storing garlic in plastic bags or containers, which can retain moisture and promote spoilage.

Garlic Pests and Diseases

Common pests include onion maggots and thrips, while diseases like white rot and botrytis can affect plants. Good crop rotation and proper sanitation of planting material can help prevent most problems.

Garlic is susceptible to several pests and diseases that can significantly affect its growth and yield. Onion maggots and thrips are common pests; onion maggots burrow into the soil and feed on the roots and bulbs, while thrips feed on the foliage, potentially transmitting viral diseases. White rot and botrytis (gray mold) are among the most destructive fungal diseases. White rot affects the roots, eventually decaying the entire plant, while botrytis affects the leaves and bulbs, especially under wet conditions.

To manage these issues, practice good crop rotation, avoiding planting garlic or other alliums in the same soil for several years. Use clean, disease-free planting stock and consider solarizing the soil to eliminate fungi and pests. Proper spacing and weed management also improve air circulation, which helps keep the foliage dry and less prone to fungal diseases. In some cases, applying fungicides or insecticides may be necessary, although organic options like neem oil can also be effective for mild pest control.

Garlic Companion Planting

Garlic benefits from being planted near plants that can repel pests or enhance growth. Good companions include tomatoes, peppers, and eggplants. Avoid planting garlic near peas and beans, as they can inhibit each other’s growth.

Companion planting can enhance garlic’s growth and protect it from pests. Garlic acts as a natural pest deterrent, making it an excellent companion for many garden vegetables. Tomatoes, peppers, and eggplants benefit from garlic’s ability to repel or distract pests such as spider mites and aphids. Planting garlic near these vegetables can improve their health and vitality.

However, garlic should be kept away from peas and beans. It releases substances that may inhibit the growth of legumes. Similarly, planting garlic near parsley and sage should be avoided as they can compete for similar nutrients. On the other hand, planting garlic near carrots can help repel carrot flies, demonstrating garlic’s protective qualities in a vegetable garden.
