The Best Time to Plant Garlic in Michigan: A Guide for Garlic Enthusiasts

Now that Halloween has come and gone, you may find yourself pondering the fate of the surplus garlic you purchased to ward off vampires. Fear not! This is the perfect time to plant garlic, an endeavor that requires minimal effort but yields bountiful rewards come summer. Not only is garlic easy to cultivate and maintain, but it also adds a delightful touch to a variety of dishes while offering numerous health benefits.

Discovering the Wonders of Garlic

Garlic, a member of the Allium family, shares its heritage with onions, leeks, and chives. Originating from Asia, garlic boasts two subspecies: hardneck and softneck. It’s worth noting that within these subspecies, there exists a multitude of varieties. The bulb of the garlic plant comprises multiple cloves, while the stalk extending from the bulb is known as the “neck.”

Hardneck garlic, scientifically classified as Allium sativum ssp. ophioscorodon, features a long flowering stem called a scape. This scape culminates in an umbel, which encapsulates the central growing point. Typically, hardneck garlic bulbs contain four to twelve cloves. Known for their spiciness, hardneck varieties thrive even in the harsh winters of northern Michigan. Popular hardneck garlic varieties include Porcelain, Marbled Purple Stripes, Purple Stripe, Glazed Purple Strips, and Rocambole.

On the other hand, softneck garlic, scientifically labeled as Allium sativum ssp. sativum, is characterized by irregularly shaped cloves, ranging from 8 to 20, depending on the variety. It is believed that softneck garlic developed more cloves to compensate for the absence of an umbel. Due to their “soft neck,” these varieties are easier to braid. Softneck garlic also tends to have longer storage capabilities, making it a common sight in most grocery stores.

Unveiling the Health Benefits

Numerous studies have unveiled the vast array of health benefits associated with garlic consumption. Rich in Vitamins C and B6, Manganese, and antioxidants, garlic offers a remarkable nutritional profile. The compound alliin is found in intact raw garlic. However, when garlic is crushed or chopped, an enzyme called allinase is activated, converting alliin into allicin. Allicin, responsible for the distinctive sulfur smell, serves as an antibacterial compound and is responsible for many of garlic’s health benefits.

It’s important to note that allicin is only released when garlic is crushed or chopped. To reap the full benefits, it is advisable to crush garlic and allow it to sit at room temperature for 15-20 minutes before consumption or use. Research has shown that garlic supplements can help lower total cholesterol and regulate blood pressure. Garlic also strengthens the immune system, reducing the frequency and duration of colds. Additionally, studies have revealed that garlic may enhance memory, although primarily observed in rats. It’s important to remember that individual responses to garlic consumption may vary.

Planting Garlic: A Journey Begins

The ideal time to plant garlic in Michigan is typically in mid-late October, extending until the ground freezes. Plant the cloves, ensuring the root side faces downward, approximately two-to-three inches below the soil surface. Maintain a spacing of six inches between cloves within a row, while keeping rows one foot apart. To protect the bulbs, it’s recommended to apply about six inches of loose straw mulch to the bed. Early season weed control is crucial, and regular watering, typically once a week, will nurture your garlic crop.

In late spring, for hardneck varieties, you can expect the emergence of scapes from the center of the plant. Initially, the scapes grow straight, but eventually, they curve into a circular shape. Many growers opt to trim the scapes as they divert energy from the bulb, potentially resulting in smaller bulbs. These scapes present a wealth of culinary opportunities. From garlic scape pesto to grilling them as a delectable side dish or incorporating them into marinades, the possibilities are endless.

While different garlic varieties may mature at varying times, in northern Michigan, most varieties are ready for harvest in early July. To help you remember when to plant and harvest your garlic, a farmer from the region once advised planting during the MLB World Series and harvesting during the MLB All-Star Game.
