Ranging from mild and mellow to bold and spicy, garlic is a culinary treasure. Whether used raw or cooked, it adds a distinctive flavor to dishes.
General Information
Softneck garlic adapts to a wide range of climates and forms bulbs without requiring cold temperatures, making it ideal for regions with mild winters-though it also grows well in cold-winter areas. Softneck cloves are generally smaller than those of hardneck varieties; they have a longer shelf life (up to a year) and are excellent for braiding.
Hardneck garlic offers a bolder, more complex flavor and produces edible flower stalks in the spring known as "scapes." Hardneck varieties typically store for 4 to 6 months. Many varieties require a period of cold temperatures (vernalization) to form bulbs; this occurs naturally in cold-winter regions, but growing them in the South or mild coastal areas requires pre-chilling. Simply store the bulbs in a dark environment at 40°F (approx. 4°C) with 80% relative humidity for 40 to 45 days before planting.
General Planting
When to plant outdoors: In cold regions, garlic is planted in the fall and harvested in the summer. Individual cloves can be planted from mid-September to mid-November. Garlic is frost-tolerant, but ideally, it should be planted 4 to 6 weeks before the ground freezes to allow the cloves time to establish roots.
In mild-climate regions, garlic can be planted as late as January. Do not separate the cloves until planting time, and keep the papery skins intact as much as possible. Plant cloves 2–3 inches deep and 6–8 inches apart, with the pointed end facing upward.
Optimal Growing Conditions
Soil
Fertile, well-draining soil enriched with well-rotted compost. Soil pH should range from 6.0 to 7.0 (suitable for most vegetables).
Water
Keep the soil moist but not waterlogged. Reduce watering as harvest approaches to prevent the outer layers from rotting. In humid climates or areas with poor drainage, use raised beds to improve drainage. In regions where the soil does not freeze or thaws during winter, keep the soil moderately moist.
Exposure
Ample sunlight provides ideal growing conditions, though garlic can also thrive in partial shade.
Fertilization
Once new shoots emerge in the spring, apply a high-nitrogen fertilizer, such as fish emulsion or blood meal. Reapply after approximately two to three weeks.
Special Care
Weed regularly to minimize competition for water and nutrients. In spring, most hardneck garlic varieties produce tall stalks that curl at the top and form flower buds; however, in regions with mild winters, some varieties may not produce these stalks.
These flower stalks-known as "garlic scapes"-should be removed so the plant directs its energy toward bulb development. Scapes are edible and have a milder flavor than the cloves. Softneck garlic may also produce scapes due to stress from drought or cold temperatures; these should be removed as well.
Mulching
After planting, apply a 2- to 4-inch layer of mulch (such as straw, untreated grass clippings, or shredded leaves) to retain moisture, insulate the cloves and any winter shoots, and help prevent frost from heaving the bulbs toward the soil surface.
Loosen the mulch in the spring to allow seedlings to push through if the layer is thick or compacted. In very cold climates, remove the mulch in late winter or early spring after the last hard frost to allow the soil to warm up, then reapply it once the seedlings have emerged.
