Garlic is a beloved ingredient in many kitchens around the world, cherished for its strong flavor and numerous health benefits. While growing garlic can be easy, many gardeners experience disappointment when their bulbs turn out smaller than expected. In this guide, we'll explore the best practices for successfully cultivating larger garlic bulbs, maximizing your harvest, and ensuring your plants thrive.
Despite the idea that planting occurs in the growing season, garlic can be planted in the fall when other plants are dying back. This may seem counterintuitive, but garlic is remarkably hardy and thrives when planted during this time. To achieve the best results, timing is crucial; ideally, garlic should be planted approximately three weeks after the first frost date in your area. This allows the garlic to undergo the necessary cold period known as vernalization, essential for proper bulb formation.
For those in milder climates, late autumn planting is advisable. Conversely, gardeners in colder regions should aim to plant earlier in the autumn to ensure that their garlic receives enough chilling hours, ideally around 10 weeks at temperatures below 45°F (7°C).
Garlic does not tolerate soggy, poorly-drained soil. If your garden has clay or heavy soil, consider planting in raised beds to enhance drainage. A sunny location is also critical, as garlic needs ample sunlight to flourish. Before planting, clear the soil of any remnants from previous crops and weeds. Amending the soil with rich compost and a broad-spectrum organic fertilizer like blood, fish, and bone meal will provide vital nutrients necessary for healthy growth. If you prefer to avoid animal-derived products, a potassium-rich general-purpose organic fertilizer or onion feed will also suffice.
Once you've prepared the planting site, it’s time to plant the garlic cloves. Choose the largest cloves as they tend to produce bigger bulbs. Space the cloves about 6 inches (15 cm) apart in both directions, and plant them in holes approximately 5 inches (12-13 cm) deep. Ensure you place the flat side down (where roots will emerge) and the pointed side up (where leaves will sprout). This correct positioning plays a vital role in the bulbs' eventual size and health.
For regions that experience heavy winter rainfall, consider planting the cloves in pots or plug trays kept in a sheltered area such as a greenhouse. This method prevents waterlogging while still allowing the garlic to germinate successfully.
Garlic serves as an excellent companion plant, repelling various insect pests. For optimal growth, you can plant garlic alongside crops like apple and pear trees. When selecting garlic varieties, you will generally choose between softneck and hardneck types. Softneck varieties, commonly found in supermarkets, store well and are ideal for warmer climates. Hardneck varieties have fewer, but larger cloves, pack more flavor, and are preferred in colder areas.
Additionally, hardneck garlic produces scapes—curled flowering spikes that can be harvested a few weeks before the bulbs, providing a delicious bonus crop.
Once your garlic is planted, cover the area with a layer of mulch, preferably leaves, to insulate the soil during the winter months. This insulation helps protect these tender shoots and encourage root development before the coldest weather arrives. If you reside in a particularly cold climate, a thicker layer of mulch—around 2 inches (5 cm)—will provide extra warmth and protect your developing plants.
As spring approaches and temperatures rise, it’s important to manage weed growth and keep the soil consistently moist—but not saturated. Senior garlic gardeners agree too much water at this stage can cause problems, so maintain a careful balance as the plants mature.
To determine when your garlic is ready for harvesting, keep an eye on the lower leaves. When they start to yellow and wilt, that’s your cue. Be mindful not to wait too long, as delaying harvest can lead to decreased bulb quality and shortened storage life.
To harvest, gently ease the bulbs from the soil using a fork while pulling on the foliage above. The timing of the harvest will vary based on when you planted the cloves, but you can generally expect to harvest from late spring to late summer.
After harvesting your garlic, avoid cleaning them immediately. Store them in a dry place to allow for proper drying, which can take two to three weeks. Once dry, garlic can be stored in a cool, dark place for several months. If you prefer, you can trim the stalks and roots to facilitate long-term storage in breathable sacks or nets.
