Understanding Garlic Varieties
When planting garlic in Michigan, you will need to choose between Hardneck and Softneck varieties. Each type has its own advantages, and certain varieties perform better in Michigan’s climate.
Hardneck Versus Softneck
Hardneck garlic varieties are known for their hard, central stalk and larger cloves. They tend to have a stronger flavor and produce scapes, which are edible flower stalks. These varieties are well-suited for cold Michigan winters, making them popular among local growers.
Softneck garlic, on the other hand, is more flexible and typically does not produce a flower stalk. This type is often used for braiding. Softneck varieties have a milder flavor and generally store longer than Hardneck garlic. While they can also grow in Michigan, they might not withstand extreme cold as well as Hardneck types.
Choosing Garlic for Michigan Climates
Michigan’s USDA hardiness zones range from 3 to 6, which means winters can be quite cold. Hardneck garlic varieties like German Extra Hardy are ideal for these conditions due to their robustness. These varieties tolerate freezing temperatures and can thrive throughout the winter season.
Softneck garlic varieties can be grown in Michigan but require more care to protect them from freezing. If you decide to grow Softneck varieties, make sure to mulch heavily to insulate the bulbs during colder months. The timing of planting is also crucial; aim for mid-September to the end of October for the best results.
Popular Varieties in Michigan
Several garlic varieties are particularly popular among Michigan growers. German Extra Hardy, a Hardneck variety, is favored for its large bulbs and strong, robust flavor. It is very cold-tolerant, making it a safe bet for Michigan’s harsh winters.
Another popular Hardneck variety is Georgian Crystal. Known for its mild yet rich flavor, this variety has consistent growth and performs well in colder climates.
Among Softneck varieties, you might consider types such as California Early or Italian Loiacono, which are known for their excellent storage life and milder taste. These choices, while less cold-hardy, can still produce impressive yields with the right care.
Soil Preparation

For successful garlic planting in Michigan, it’s essential to prepare the soil properly. Focus on adjusting the pH levels, enhancing soil fertility, and ensuring good drainage.
Testing Soil pH
Garlic grows best in soil with a pH between 6.0 and 7.0. Start by testing your soil to determine the current pH level. You can purchase a soil pH test kit at a garden center or send a sample to a lab for more accurate results.
If the pH is too low (acidic), add lime to raise it. Conversely, if the pH is too high (alkaline), sulfur can lower it. Adjusting the pH helps garlic absorb nutrients more efficiently.
Accurate pH adjustment ensures healthier plants. Testing should be done at least a few weeks before planting to allow time for amendments to take effect.
Improving Soil Fertility
Garlic thrives in fertile soil rich in organic matter. Consider adding compost or well-rotted manure to enhance soil fertility. Compost not only improves nutrient content but also promotes beneficial microbial activity.
Use fertilizers high in nitrogen and potassium to support robust growth. You can apply a balanced fertilizer or one specifically formulated for vegetables.
Mix organic matter into the soil during fall to give it time to integrate and improve soil structure by planting time. This increases soil fertility, providing better conditions for garlic.
Ensuring Good Drainage
Drainage is crucial for preventing waterlogged soil, which can rot garlic bulbs. Plant garlic in well-drained, loamy soil. Avoid heavy clay soils or amend them with organic matter to improve texture.
Raised beds are a good option if your garden soil has poor drainage. They allow better control over soil conditions. When planting, space garlic cloves 4-6 inches apart and maintain rows 6-8 inches apart to ensure adequate drainage and airflow.
Proper tilling can help break up compact soil, enhancing drainage. Regular soil monitoring ensures optimal conditions for growing garlic.
Planting Guidelines
Growing garlic in Michigan requires specific timing and proper techniques to ensure a healthy harvest. Below are detailed planting guidelines that will help you successfully plant garlic in Michigan.
Best Time to Plant in Michigan
The optimal time to plant garlic in Michigan is from mid-September to the end of October. This period allows the garlic to establish strong roots before the ground freezes. It’s important to plant your garlic cloves before the first frost to ensure they get a head start on growth. Aim for soil temperatures around 50-60°F when planting, as this will aid in root development.
Planting Depth and Spacing
When planting garlic, space the cloves 4-6 inches apart in rows that are 12 inches apart. Ensure each clove is planted with the pointed end up and covered with about 2-3 inches of soil. For a double-row system, maintain a spacing of 36 inches between double rows. Proper spacing allows the garlic plants to have enough room for growth and helps prevent overcrowding, which can lead to disease.
Mulching and Insulation
Once your garlic is planted, adding a layer of mulch is crucial. Use straw or another organic material to cover the planted area.

Look at the garlic leaves. When the lower leaves turn brown but the top leaves remain green, it’s time to harvest. Typically, this happens in mid to late summer. Another sign is bulb size. Dig gently around a few plants to check the bulb size and skin. The skin should be tight and papery, ready for curing.
Proper Harvesting Techniques
Use a garden fork or spade to lift the garlic bulbs gently. Avoid pulling the plants directly as this can damage the bulbs. Shake off excess soil but keep the leaves intact. This helps in the initial drying process. Handle bulbs carefully to avoid bruising, which can lead to rot in storage.
Curing and Storage Practices
Hang garlic in a well-ventilated area with good air circulation. Leave them to dry with the leaves attached for 2-3 weeks. Once cured, cut the leaves and roots, cleaning off any remaining dirt. Store garlic in a cool, dry place, ideally around 50-60°F. Proper storage keeps garlic usable for several months.
Additional Considerations
Growing garlic in Michigan involves more than just planting and watering. Understanding crop rotation, planting methods, and organic versus conventional growing can improve your yield and soil health.
Crop Rotation and Succession Planting
Crop rotation is essential for garlic cultivation. Rotate garlic with non-allium crops such as legumes, grains, and leafy greens to minimize pests and soil diseases. Avoid planting garlic in the same spot more than once every three to four years.
Succession planting is another key practice. After harvesting garlic in late summer, plant cover crops like clover or vetch. These crops improve soil fertility by adding organic matter and nutrients. You can also plant late-season vegetables like spinach or kale.
Container and Raised Bed Planting
Garlic grows well in containers and raised beds. For container gardens, use pots at least 12 inches deep with good drainage. Raised beds should be 8-12 inches high, using fertile, well-drained soil. Raised beds help manage soil health and moisture levels, reducing the risk of waterlogging or diseases.
Space garlic cloves about 4-6 inches apart. Raised beds and containers can be easier to manage and allow for better soil preparation and weed control. Mulch with straw or leaves to retain moisture and suppress weeds.
Organic Vs. Conventional Growing
Choosing between organic and conventional methods depends on your gardening goals. Organic growing avoids synthetic pesticides and fertilizers. Instead, use compost and natural pest deterrents like neem oil or garlic spray. This method enriches the soil with organic matter and supports a healthier ecosystem.
Conventional growing uses chemical fertilizers and pesticides for higher yields and easier pest control. While effective, these products can impact soil health and biodiversity over time. Weigh the benefits and drawbacks based on your specific needs and preferences for garlic cultivation.
Embrace proper care and pruning practices. Whether for culinary uses or health benefits, flavorful garlic depends on your chosen growing methods.
