Q: What is the best way to grow and dry garlic? I live in Minnesota, is there a list of herbs that I can grow, harvest and dry for my personal use?

A: Growing garlic is fairly easy. However, harsh Minnesota weather isn’t exactly the ideal growing climate for garlic.

Growing Garlic

Latin name: Allium sativum L. 

Soil condition: Garlic thrives in well-drained soil with a pH level between 4.5 and 8.3. If you are not sure if the soil to too acidic or too basic, test the soil by purchasing a pH test strip from your local garden store. Garlic is not drought tolerant and does not do well in extremely wet soil.

Temperature: Garlic will typically germinated in 60 to 80 degree weather.
Maintenance: Keep an eye out for these pests: Onion thrips, armyworms and onion maggots. Although pests are not a big issue with garlic, it is something to keep in the back of your mind. If you are planning on growing garlic, make sure you stay on top of weeds, as garlic does not fare well against them.

Drying Garlic

Regardless of which method you choose to dry garlic, the most important component is good air circulation. You will want to store your drying garlic in a dark and cool location.
Hanging garlic: This is the method I recommend as it efficiently dries the garlic and minimal space is required. Tie 7-12 garlic stalks together to forms a bundle. Check on the garlic maybe once a month. The type of garlic will depend on the drying time, however, the process will take anywhere from 6 to 8 months.

Growing Herbs in Minnesota

The USDA Hardiness Zones notes that Minnesota's average minimum winter temperatures range from -20 to -45 degrees. That being said, growing herbs indoors throughout the winter months is a great option for colder climates.

Growing Herbs Indoors

Growing herbs indoors is a great way to enjoy summer flavors during the cold winter months. These herbs do fairly well indoors: basil, bay, cilantro, chives, dill, ginger, lemon verbena, marjoram, mint, oregano, parsley, rosemary, sage and thyme. Keep in mind each herb’s growing requirements (watering, sunlight, fertilizer, etc.).
