Garlic is one of the best vegetables for fall planting. It is easy-to-grow, but has a somewhat long season, as it is not harvested until the following summer. Don’t let the delay in harvest put you off from planting this fantastic addition to the vegetable garden.
When To Plant Garlic
For best yields, garlic is most commonly planted in the fall. Garlic can be planted as late as 4 to 6 weeks before the ground freezes. Even in cold climates, garlic is hardy enough to overwinter and resume growth the following spring. If the weather after planting is mild, garlic shoots may emerge in the fall but will die back after a hard frost. This will not harm the plants.
How To Plant Garlic
To plant garlic, break cloves from a bulb, being careful not to damage the basal plate at the bottom of the cloves where the roots emerge. Do not peel the cloves before planting. Place the cloves 4 to 6 inches apart with the pointed side up and cover them with 1 to 2 inches of soil, firming gently. Water after planting and mulch with 4 to 6 inches of clean straw or chopped leaves to help keep the soil moist and provide some insulation during winter.
Soil Considerations For Garlic
Garlic benefits from being planted in soil amended with organic matter like compost, rotted manure, or chopped leaves. In heavy soils, plant in raised beds to ensure that there is good drainage.
When To Fertilize Garlic
Garlic requires fertile, well-drained soil, and it is moderate to the heavy feeder. Like other plants in the onion family, garlic has shallow roots and benefits from several fertilizer applications throughout the season.
Once the garlic begins growing in spring, it benefits from an application of nitrogen fertilizer to promote vigorous growth and good yields of large bulbs. Stop fertilizing in early summer to avoid delaying bulb formation. Watering during prolonged dry and hot spells also helps promote strong bulb growth.
What Are Bulbils?
In late spring, hardneck varieties of garlic send up flowering stalks that produce a shoot that grows in a curve. These shoots (called “scapes”) will form small bulbils if left on the plants. The bulbils use energy that would otherwise be used to form bulbs underground, so most growers remove the scapes as soon as they appear. The scapes can be chopped finely and used in cooking or salads to provide a mild, garlic flavor.
Bulbils can be allowed to mature and planted in the garden if desired. Because they are quite small, it will take several years for bulbils to produce full-sized bulbs.
Summertime Garlic Care
In mid-summer, mulch can be removed from garlic beds if desired. Stop watering so the soil begins to dry out. This helps to dry the outer layers of the bulb and hastens the maturing process, giving the best chance for a good curing and long storage life of the bulbs.
Harvesting & Curing Garlic
Harvest garlic when the leaves start to dry down in late August or early September when at least 4 to 6 green leaves remain. These green leaves will form the papery skin that covers the bulbs. Gently dig the garlic, being careful not to bruise the bulbs. Don’t leave bulbs in the ground too long after maturing, as the cloves will naturally begin to root and start the whole process over.
After digging the bulbs, lay them out in a ventilated, shady area on an old screen or another platform that allows for good aeration as the bulbs dry. Be sure bulbs do not get wet after harvest as they can start to root or mold if not cured and dried properly. After about 2 to 3 weeks, when the roots feel dry, remove them and any excess soil by rubbing or trimming them off. Do not wash bulbs as moisture can cause them to mold or rot.
Saving Your Garlic Bulbs
Save the largest bulbs for replanting after curing. The best time to start plants over again is from late September to early October. Garlic typically takes 2 to 3 seasons to acclimate to a new climate, resulting in more vigorous growth and better yields, so saving some bulbs for replanting is very worthwhile.
