How to grow garlic

Garlic is a kitchen staple prized for its flavor, versatility, and numerous health benefits. Easy to cultivate in your garden, garlic requires little space, making it ideal even for smaller gardens or containers. Growing your garlic ensures freshness and allows you to choose from a wide variety of flavorful heirlooms and specialty types. Follow this comprehensive guide to planting, cultivating, and harvesting garlic, ensuring a plentiful harvest of homegrown cloves.

How to grow garlic from seed

Garlic isn’t typically grown from traditional seeds; rather, it is grown from individual cloves separated from a garlic bulb. Select healthy, firm garlic bulbs from a trusted source or nursery. Break the bulb into individual cloves, making sure to leave the papery skin intact. Plant the cloves with the pointed end facing upwards, approximately 2 inches deep. Cover with soil and mulch gently. Each clove will eventually develop into a full garlic bulb, providing a reliable harvest.

When to plant garlic

Garlic performs best when planted in the fall, typically around 4 to 6 weeks before the ground freezes. This usually falls between late September and November, depending on your local climate. Planting garlic in autumn allows the cloves to establish roots and experience the cold period needed for proper bulb development in the spring and summer. In warmer climates, garlic can be planted in late winter or very early spring.

How far apart to plant garlic

Garlic cloves should be spaced about 4 to 6 inches apart in rows. Rows should be spaced approximately 12 to 18 inches apart. Adequate spacing ensures each plant has enough room for bulb development and reduces competition for nutrients, water, and sunlight, ultimately leading to healthier, larger garlic bulbs.

How much space garlic needs

While garlic doesn't require a large area, proper spacing is essential for optimal bulb size and health. Each clove needs about 4 to 6 inches of individual space, with rows spaced at least 12 inches apart. Ensuring adequate space prevents disease by allowing better airflow and discourages pests attracted to crowded plants.

Does garlic need a trellis

Garlic does not require a trellis or any other support structure. As a bulb crop, garlic grows underground, producing upright foliage that typically stands around 12-18 inches tall. This simple growth habit means garlic can be easily managed in garden beds or containers without special support.

Where to plant garlic

Choose a sunny location with well-drained, fertile soil. Garlic prefers loamy soils rich in organic matter, so incorporating compost or aged manure before planting improves growth and bulb size. Avoid areas prone to waterlogging, as garlic bulbs may rot in overly damp conditions. Raised beds or elevated planting areas are beneficial, especially in regions with heavy clay soil.

How much sunlight garlic needs

Garlic thrives in full sun, requiring at least 6 to 8 hours of direct sunlight daily. Adequate sun exposure encourages vigorous growth, resulting in larger bulbs with stronger flavor. If garden space is limited, ensure that your garlic is planted in one of the sunniest spots available for best results.

What temperature does garlic grow in

Garlic grows best in cooler climates and prefers temperatures ranging from 32°F to 75°F (0°C to 24°C). It requires a cold period of at least four to six weeks at temperatures below 40°F (4°C) for optimal bulb development. Moderate temperatures during spring and early summer provide ideal growing conditions for healthy bulbs.

Can garlic handle frost

Garlic is highly frost-tolerant and often requires exposure to frost or cold weather (vernalization) to trigger proper bulb formation. Mature garlic plants can handle temperatures well below freezing. Fall-planted garlic typically endures winter conditions, emerging robustly in the spring. Mulching helps protect cloves during particularly harsh winters.

How much water garlic needs

Garlic requires consistent moisture, especially during its active growing phase in spring. Aim for about 1 inch of water per week, adjusting based on rainfall. Even watering promotes uniform bulb growth and reduces stress. However, as garlic approaches maturity in summer, reduce watering to help bulbs dry out and harden for harvest.

How often to water garlic

Water garlic deeply and regularly, typically once per week during dry periods. Monitor soil moisture by checking the top inch—if it feels dry, it's time to water. Avoid excessive watering, especially near harvest, as overly moist soil can cause bulbs to rot or mold, negatively affecting your crop’s quality and storage life.

How long garlic takes to grow

Garlic requires patience, typically taking between 8 to 9 months from planting to harvest. Fall-planted garlic is ready to harvest the following summer, usually around July or August. Garlic growth occurs in two phases: root and foliage development during cooler months, followed by rapid bulb enlargement as days lengthen and temperatures warm.

When to harvest/pick garlic

Harvest garlic when about half of the leaves have turned yellow or brown, typically in midsummer. Timing your harvest is crucial—too early and bulbs will be small; too late and cloves may split apart. Test readiness by digging up one bulb and checking size and clove definition. If satisfied, proceed to harvest the rest of your garlic.

How to harvest/pick garlic

To harvest garlic, gently loosen the soil around bulbs with a garden fork or shovel. Carefully lift bulbs from the ground without damaging them. Brush off excess soil, but avoid washing the bulbs. Garlic must be cured by drying in a well-ventilated, shaded location for 2 to 3 weeks. Once fully cured, trim leaves and roots, and store bulbs in a cool, dry place.

Can you grow garlic indoors

While garlic prefers outdoor cultivation, it can be grown indoors for smaller harvests or garlic greens. Choose large containers with drainage holes, filled with well-drained, rich potting mix. Place containers in a bright, sunny location or under grow lights. Indoor garlic growth tends to be slower and bulbs smaller, but you can still enjoy flavorful garlic greens year-round.

How to grow garlic in pots/containers

Garlic grows well in pots or containers at least 8 inches deep, providing adequate space for roots. Ensure good drainage and use a high-quality potting mix enriched with compost. Plant cloves 4 inches apart, covering them 2 inches deep with soil. Water regularly to maintain consistent moisture. Containers should be placed in full sun, and garlic grown this way requires careful watering, as container soil dries more quickly than garden beds.
