Sow and Plant
Start seeds indoors in late winter to early spring when growing cold-hardy bunching varieties. Or, plant large sets close together and harvest the plants when young.
Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.
Any immature onion can be eaten as a green onion, or scallion.
Pull individual plants as you need them in the kitchen. With perennial bunching varieties, lift clumps in spring or fall and replant some of the divisions.
Slugs often chew holes in onion leaves in wet weather.
