Growing garlic is not difficult. Even if you’re not a seasoned gardener, you can grow great garlic if you start with great organic seed garlic.
1) Preparing the soil
Garlic will grow in just about any soil, but to grow a good size bulb you will need to have good fertile soil with lots of organic matter and good drainage. Well rotted manure or compost is a good soil amendment for garlic. If you are not sure of the quality of your soil send a soil test off to your local extension service. Garlic will do best in a soil with a pH level between 6 and 7.
2) Preparing the garlic
Just prior to planting, break apart each head of garlic by hand until you have all the cloves separated. Do not use a tool for this as you do not want to bruise the garlic. Each clove planted will yield a head of garlic the following growing season. The larger cloves will produce the larger size heads of garlic, smaller cloves will produce a smaller head. Some gardeners prefer to save the smaller cloves for eating, pickling or planting close together to eat as green garlic in the spring.
Garlic is usually planted in early October in the north and from November through January in the south. Northern growers should plant four to six weeks before the ground freezes in order to insure good root growth prior to winter. Here in Vermont we plant from Mid-October to mid-November. Plant the cloves, 4 – 5 inches deep and 5 to 6 inches apart with the pointed side up and growth plate (where the roots emerge) down, cover with soil and pat down.
(Southern growers – garlic needs to go through a cold spell to trigger sprouting. If you live in a climate where the temperature does not drop below 40 degrees, place your seed garlic in a cold spot (40-50 degrees) for 2 – 3 weeks before planting)
When you are done planting mulch the rows with 3-4 inches of mulch. Mulch can consist of material you may have readily available — straw, leaf litter, compost. Grass or hay are not recommended as it will drop lots of weed seeds in your bed. Mulch will protect your garlic during fluctuating temperatures in the winter and early spring. The mulch can be removed in the spring after the threat of a hard freeze is over to help the soil warm up, or it can be left in place to help with weed control and preserve soil moisture.
5) Spring and early summer
If you live in a dry climate you may need to water your garlic. Garlic likes to be kept evenly moist especially during leaf production. Soak the soil throughly, sandy soils may require more frequent watering. Garlic does not like competition from weeds, so try to keep them to a minimum.
Hardneck garlic will produce a flower or bubil in the spring, in Vermont our garlic scapes come in June. These should be clipped off, when the scapes begins to curl, to promote healthy bulb growth. Scapes are seasonal culinary treasures to garlic enthusiasts and gourmet cooks. A fully mature scape looks great in a flower arrangement!
Harvesting usually takes place between June and July, depending on your location. Harvesting the garlic too early will result in smaller heads, harvesting too late will result in overly mature garlic that will not store well. One indicator that the garlic is ready for harvest is when the lower half of the leaves turn yellow and brown. You can always pull a few heads to decide if it’s time to harvest. If the head is good sized and the cloves fill the skin it is ready for harvest.
Harvest the garlic head, with the plant attached, using a shovel. Garlic can bruise, so handle carefully. Clean off excess soil and bundle in groups of five to ten plants. Hang them in a warm, dry, airy place, out of the sun, for 3 to 4 weeks to cure. If you live in a very humid climate, you may want to remove the stems and roots for the drying/curing process. After curing (check the clove wrappers inside the bulb to make sure they are dry) trim the stem and the roots and store in a cool (50-55 degrees), dry place for the winter months.
