Michelle Hill

Growing garlic is a popular pastime for many Ohio gardeners. Not only is it a flavorful addition to many dishes, but it is also relatively easy to grow and requires minimal maintenance. Garlic can be planted in the fall or spring, depending on your preferences and the weather conditions in your area. In this article, we will provide you with some tips and tricks for planting garlic in Ohio, so you can enjoy a bountiful crop of this delicious herb.

Choosing the Right Garlic Variety

Before you start planting garlic, it’s essential to choose the right variety for your area. There are two main types of garlic: hardneck and softneck. Hardneck garlic is more suitable for colder climates, while softneck garlic is better suited for milder regions. In Ohio, hardneck garlic is the preferred variety due to the state’s harsh winters. Some popular hardneck garlic varieties for Ohio gardeners include:

  • Rocambole
  • Porcelain
  • Marbled Purple Stripe
  • Music

When selecting garlic bulbs for planting, look for large, healthy bulbs with unbroken skins. Avoid bulbs that are moldy or have soft spots, as they are likely to be diseased or damaged.

Preparing the Soil

Garlic grows best in well-drained soil with a pH level between 6.0 and 7.5. If your soil is too acidic, add lime to adjust the pH level. If it’s too alkaline, add sulfur. To prepare the soil for planting, remove any weeds or debris and add compost or well-rotted manure to provide nutrients for the garlic. Mix the compost or manure into the soil to a depth of at least 6 inches.

Planting the Garlic

Garlic is typically planted in the fall, but it can also be planted in the spring. If you’re planting in the fall, aim to plant the garlic about six weeks before the ground freezes. In Ohio, this is usually around mid-October. If you’re planting in the spring, wait until the soil temperature reaches at least 50 degrees Fahrenheit.

To plant garlic, separate the cloves from the bulb and plant them root-side down, about 2 inches deep and 4-6 inches apart. Cover the cloves with soil and water well. If you’re planting multiple rows, space them at least 18 inches apart to allow for proper air circulation.

Caring for Your Garlic Plants

Garlic requires minimal care once it’s planted. Water the plants regularly, especially during dry spells, but avoid overwatering, as garlic doesn’t like to sit in soggy soil. Fertilize the plants with a nitrogen-rich fertilizer in the spring, but avoid fertilizing in the fall, as this can encourage the plants to grow too quickly, which can lead to disease.

Garlic is relatively pest-resistant, but you may notice some pests, such as aphids or mites, on occasion. If this happens, spray the plants with a mild soap solution or insecticidal soap to deter the pests.

Harvesting and Storing Garlic

Garlic is typically ready to harvest in late spring or early summer, depending on when it was planted. Look for the leaves to turn yellow or brown and begin to dry out. This is a sign that the garlic is ready to be harvested.

To harvest garlic, carefully dig up the bulbs with a garden fork or trowel. Be careful not to damage the bulbs or the surrounding plants. Shake off any excess dirt and allow the bulbs to dry in a warm, well-ventilated area for a few weeks. Once the bulbs are fully dry, trim off the roots and the stems and store the garlic in a cool, dry place.


1. How long does it take for garlic to grow in Ohio?

Garlic typically takes about 8 months to grow from planting to harvest in Ohio. However, this can vary depending on the variety of garlic and the weather conditions in your area.

2. Can garlic be grown in containers?

Yes, garlic can be grown in containers. Choose a container that is at least 12 inches deep and 8 inches wide, and fill it with well-draining soil. Plant the garlic cloves about 2 inches deep and 4-6 inches apart, water well, and place the container in a sunny location.

3. How do I know when it’s time to harvest my garlic?

Garlic is ready to be harvested when the leaves turn yellow or brown and begin to dry out. This typically occurs in late spring or early summer, depending on when the garlic was planted.

4. Can I plant garlic in the same spot every year?

It’s not recommended to plant garlic in the same spot every year, as this can lead to a buildup of disease and pests in the soil. Instead, rotate your garlic crops every year, planting them in a different location in your garden.

5. How do I store garlic for long periods?

To store garlic for long periods, keep it in a cool, dry place with good air circulation. Avoid storing garlic in the refrigerator, as this can cause it to sprout or become moldy. Garlic can be stored for up to 6 months in ideal conditions.


Planting garlic in Ohio is a simple and rewarding activity that can provide you with a bountiful crop of this delicious herb. Remember to choose the right garlic variety for your area, prepare the soil properly, and care for your plants throughout the growing season. With a little bit of effort and patience, you can enjoy the flavor and health benefits of fresh garlic straight from your garden.
