Harvesting Onions and Garlic

If you planted onions or garlic in your garden, the time is upon us to start harvesting those crops. Garlic typically matures sometime in early June and, depending on the species, can be harvested till mid-July. Your garlic is ready to harvest when approximately five green leaves are left on the plant, and the rest are turning brown. It’s best to stop watering garlic a couple of weeks before you plan to harvest, so it’s easier to pull. Onions are ready to pull when over half of the tops of your plants have fallen over. This happens when the bulbs have reached their mature full size. Both plants should be allowed to dry out of direct sunlight for several weeks before being stored for the year. You can braid the stalks of garlic together to hang them for storage or cut the stalks and roots off (1” for garlic, ½” for onions) above the bulb and store in a cool, dry location. Both should be stored at temperatures below 40 degrees for the longest shelf life in an area with low humidity to prevent sprouting. Garlic can be stored for 9 months or more, depending on the variety, while onions will last a shorter period of time, depending on the variety.
