Garlic is a versatile and easy-to-grow plant that can be cultivated in various climates. To grow garlic, start by choosing the right variety for your region and preparing the soil. Plant the cloves in the fall, placing them about 2 inches deep and 6 inches apart. Ensure that the cloves are placed with the pointed side up. Water the garlic regularly, but avoid overwatering. Harvest the garlic when the leaves turn yellow and dry. Cure the bulbs in a cool, dry place for a few weeks before storing them. With proper care, you can enjoy a bountiful harvest of flavorful garlic.
Garlic, scientifically known as ​Allium sativum​, is a popular garden plant that is simple to grow. It is a low-maintenance plant that requires little care, making it an ideal addition to any vegetable garden. Garlic is a bulbous plant that grows underground, similar to onions, leeks, and shallots. There are various garden-friendly varieties to choose from, all of which can be used to create delicious recipes in the kitchen.
Garlic has been utilized for both culinary and medicinal purposes throughout history. Its origin can be traced back to Asia, where it was used as a remedy for various health conditions. It is now primarily known for its robust flavor, which is well-suited for seasoning and as a base ingredient in a variety of popular dishes.
The best way to cultivate garlic is by planting individual cloves. There are two main varieties: hardneck and softneck garlic. Hardneck garlic is more tolerant to cold temperatures and comes in a variety of flavors. It does well in colder climates in the United States and produces scapes, which are flower stems that curl and have a seed head on the end. Softneck garlic does not produce scapes and is better suited for warmer climates. This type of garlic is usually found in grocery stores and can be braided.
Uses for Garlic
Garlic can be grown in raised beds or directly in the ground. It takes up less space than other vegetables, allowing for a large number of cloves to be planted and harvested easily. This makes it ideal for small yards with big garden dreams. Although it is possible to grow garlic in a container, a yard planting is usually more convenient.
Garlic plants are not particularly attractive, so it is best to plant them in the backyard where they will not be a focal point. They should be planted in a spot that does not collect water or receive too much shade, and ideally in full sun for best results.
Elephant garlic is often mistaken for true garlic, but it is actually more closely related to leeks and has a milder flavor. It can be roasted and used in salads or spreads, but it is not recommended for recipes that call for garlic cloves.

Starting Garlic From Cloves
Garlic is a vegetable or herb that can be easily grown by planting a clove of the plant like a seed. This is the easiest way to grow it as it is difficult to raise from actual seeds. Buy garlic cloves from a nursery or order them online as grocery store garlic may not be suitable for your region’s climate and may carry diseases that could harm your soil.
Planting garlic is simple. Space each garlic clove 2-4 inches apart, plant it 2 inches deep into the soil, and cover it with soil. Leave the papery covering on the clove as it protects it in the ground. The pointy side of the clove should face up. After planting, water the area thoroughly.
Garlic can also be grown from cloves saved from the previous season’s bulbs. Save a few nice cloves to plant for the following year’s harvest.

Best Zones for Growing Garlic
Garlic grows best in USDA plant hardiness zones 4 through 9. If you are growing in colder climates, take special care to ensure that the bulb does not freeze during winter. A layer of straw can be used to protect plants in these areas. Remove the ground cover when green sprouts start to show through during the spring.
When to Plant Garlic
Plant garlic between Halloween and Thanksgiving, but adjust the timing if you live in extreme climates. The aim is to get the clove into the ground before winter so it can grow roots. Plant before the first hard freeze, when the ground is cold but not frozen, for the plant to develop roots correctly.
Those living in warmer areas can plant in the fall until December, depending on the climate. Avoid planting during very hot or very cold weather to give the plant time to establish itself. Ask your local county extension service, a local nursery or garden store for recommendations on the perfect planting window for your specific region.
Guidelines for Growing Garlic: Soil, Sunlight, and Water
Prior to planting garlic, it is essential to prepare the soil properly. Begin by enriching the soil with compost and a 5-10-10 fertilizer or bone meal, working them in at least several inches deep for optimal results. If the soil is acidic, add some lime to balance it out, as garlic prefers a pH between 6 and 7. Avoid packing the soil too tightly, as garlic thrives in looser soil conditions. If you live in an area with heavy rain or dense soil, consider planting garlic in raised beds for better drainage. Once planted, garlic doesn’t require frequent watering unless there’s a prolonged dry spell. Weeding around the plants is necessary, and mulch can be used to control weed growth, except in areas with high soil moisture. Fertilize the garlic again in the spring.

Harvesting Garlic: A Step-by-Step Guide
Harvest garlic between June and August, depending on the planting date and the plant’s condition. Observe the foliage for yellowing and falling stalks to determine the right time. Periodically, check the crop’s status by digging out one bulb with a hand spade. If it appears well-formed with a solid wrapping, then the rest are ready to be harvested.
Common Problems and Pests with Garlic
Although garlic plants are not immune to pests, they are typically less prone to them than other garden vegetables. Nematodes, a type of roundworm, can be a problem, but they can be prevented by crop rotation. Avoid planting garlic in areas where tomatoes, squash, and cucumbers have been grown, as these plants are susceptible to nematodes. Instead, plant garlic in a nematode-resistant area after harvesting. Check plant labels or ask at the garden store for nematode-resistant varieties. Thrips are another common pest that can affect garlic plants; use insecticidal soap or row covers to control them. Garlic is susceptible to diseases caused by excess moisture, such as rot and fungus, so it’s essential to ensure proper air circulation in areas with high humidity.
Garlic plants can be affected by a severe type of fungus known as white rot, which is almost impossible to cure once it sets in. Unfortunately, symptoms are not noticeable until it’s too late. If you come across this issue, it’s important to act fast and remove the affected garlic immediately. Do not compost it or plant anything in that area again.
When there is high moisture, fungus and mildew can also pose a problem. To prevent this, it’s best to water the garlic in the morning so that the sun can dry out any excess moisture on the plant. Keep an eye out for white fuzz, yellowing of the plant, and slow growth, as these may be signs of downy mildew. While fungicides can be effective, it’s better to prevent the issue if possible.
