Softneck garlic at supermarket
Garlic is perhaps the oldest plant cultivated by humans. Clay models of garlic have been found in Egyptian tombs and dried garlic cloves were found in the tomb of King Tut.
Garlic is classified as Allium sativum with two sub-species: Allium sativum var. sativum (soft neck garlic), and Allium sativum var. ophioscorodon (hard neck garlic). The common name “garlic” is thought to derive from the old Gothic word “gaar” meaning “spear,” which probably refers to the flat, pointed, spear-shaped leaves.
In northern states plant garlic soon after the average date of your first fall frost. In southern states, plant later in fall or in early spring. Garlic grows best in soil that is well-loamed and neither hard clay nor sandy. Improve soil with compost and manure ten days to two weeks prior to planting.
Garlic likes well-drained soil with its bulb above, and its roots dangling into, the water table. Plant individual cloves of garlic 1 to 4 inches deep, planting deeper the further north you live. Plant cloves 3 to 5 inches apart in rows 6 to 10 inches apart. Take care to plant with the pointed end up. Mulch with straw or hay up to 4 to 6 inches deep in northern areas, less in warmer, southern areas.
Garlic likes to grow roots in the cool fall weather, rest over winter and explode into growth in spring as soon as the weather warms. Side dress with fertilizer every few weeks when growth begins in spring until you notice the bulb swelling, then stop. If you continue to feed after the bulb begins to develop, the plant will put its energy into growing leaves and the bulbs will be of inferior size.
Garlic plants send up a curved stalk called a “scape” on which form tiny bulbets. Cut these off the plants in May, generally about Memorial Day. Shortly afterward the bulbs begin to swell. This is the time to stop fertilizing the plants.
Garlic is usually ready to harvest beginning around the 4th of July. Cut back on watering for two weeks prior to harvest—plants are easier to harvest and store better and longer if harvested from dry, rather than soggy, soil. If Mother Nature provides an abundance of rain at this time, pull the mulch back from plants and allow the soil to dry.
The outer leaves will dry up and die when harvest time is near. Harvest when the outer leaves have turned brown but the inner leaves are still green and growing. Do not allow the inner leaves to die prior to harvesting or the skin of the garlic will fall off and reduce storage time and quality.
Handle garlic gently at harvest—don’t bang together or drop into collecting container. Cure as you do onions: spread out in shade at a temperature of around 72 degrees for a week or two until the skins become dry and papery. Cover at night or if rain threatens. Store garlic under conditions similar to winter squash: about 55 degrees F. with low relative humidity. Unlike squash, however, garlic prefers darkness in storage; place in clean clay pots and cover with a clay pot saucer.
Home grown garlic is far superior to supermarket garlic in taste and varieties available. To prove it to yourself, grab some cloves of garlic from the bulb you bought at the supermarket and push a few into the soil at the edge of your garden, perhaps near the perennial herbs. Next summer when you harvest it, you’ll notice your home-grown garlic is much better than the stuff you ate from the same supermarket clove of garlic.
