Sow and Plant
Set individual cloves in prepared ground in the fall. They will root during the winter, and multiply into a cluster in late spring or early summer. Alternatively, plant first thing in spring, or grow from seed and set out seedlings in early spring.
Our Garden Planning Tool can produce a personalized calendar of when to sow, plant and harvest for your area.

Notes
Used in place of onions for concentrated flavor.
|
Harvesting
Harvest in early summer when the tops begin to fail, and the bulbs have divided into several plump bulblets. If storing shallots, cure in a dry place for 10 days after pulling the plants.
|
Troubleshooting
Onion root maggots can cause plants to collapse. Remove infested plants.
