Onion sets are immature onion bulbs grown from seed and harvested early. They're replanted to grow into full-sized onions and are easier and faster than growing from seed.

When should I plant onion sets?

For overwintering varieties, plant in autumn (September–November). For spring-planted sets, plant from February to April, depending on the weather.

How long do onion sets take to grow?

Autumn-planted sets are typically ready to harvest by June or July. You'll see green shoots within 7–10 days after planting.

Do onion sets need full sun?

Yes. Onions need 6–8 hours of full sun per day to grow healthy bulbs. Choose an open, sunny spot with good air circulation.
