Cool-Season Vegetables: How to Grow Garlic
Beloved in a wide range of dishes the world over, garlic thrives in a fall garden and is easy to grow
If you cook at all, there’s a good chance garlic is a staple in your kitchen. If you’re also a gardener, you can grow your own, choosing a variety or varieties that are perfect for your favorite dishes. Plus, the height of the plants, reaching 2 feet, and their gray-green leaves make them a nice addition to a garden bed.
Garlic is a true fall crop. You set it out in fall and harvest the next summer (you can plant in early spring, but your crop won’t be as good). It’s also easy to grow. You can find garlic bulbs (also called sets) at nurseries or in catalogs. You can try growing from bulbs picked up at your grocer’s, but they may be treated to prevent sprouting and not develop as well, or at all.
There are two distinct types of garlics: softneck and hardneck. The first are used for traditional garlic braids and do well in mild-winter climates. The second are better for cold-winter climates. Hardneck varieties are also distinguished by the loops they develop above the leaf stalks, also called scapes. The very large, appropriately named elephant garlic is actually a type of leek.

Planting and care: Break the bulbs into individual cloves. Use the largest cloves that have roots attached. Set in the soil so the points face up; the top of the clove should be about 2 inches deep, and the cloves should be set 6 to 8 inches apart; plant elephant garlic a little farther apart. Cover them and keep the soil moist but not soggy. In cold-weather climates, thoroughly cover with mulch during the winter months to prevent any soil heaving caused by temperature fluctuations.
Remove the mulch in spring and continue to keep the soil moist while the bulbs develop. Keep the garden bed well weeded, but be careful not to harm the bulbs. Stop watering when the tips of the leaves start to turn brown.
There are different schools of thought on whether to remove the scapes from hardneck garlic. If you want, remove them after they form and cook them up as a type of green — if you like the taste of the garlic you're growing, then you'll probably like the scapes.
Though garlic plants are usually pest free, they can develop some problems. Issues like thrips can usually be solved by good gardening practices. Prevent root maggots by not planting where you’ve planted other members of the onion family in the previous two years. White rot can also be a problem, as well as some other diseases. If a disease develops, pull out the affected plant and dispose of it.
Harvest: You can pick off some of the leaves to use when they are about a foot tall, but don’t remove all of them. Once about three-quarters of the leaves have turned brown, carefully remove the bulbs with a garden fork to avoid breaking them apart. You might want to harvest softneck garlic a bit earlier if you plan to braid it. Hang the bulbs in bundles in a dry, well-ventilated spot until the skins become fragile and paperlike, usually about three to six weeks. At that point, remove any dirt and cut off almost all of the roots. Store in a mesh bag in a cool, well-ventilated place out of direct sunlight.
