Frequently Asked Questions
How long does it take to grow these onions?
Around 110–130 days from sowing to harvest, depending on your climate and growing conditions.
Can I grow these in southern states?
These are long-day onions, best suited to northern latitudes (Zones 3–7). For southern gardens, short-day onion varieties are a better fit.
Do they store well after harvest?
Yes — if cured properly for 2–3 weeks in a shaded, airy spot, Sweet Giant onions store for up to 3–5 months in a cool, dry space.
Can I grow them in containers?
Yes, but use deep containers (8+ inches) filled with rich, well-draining soil to allow full bulb development.
Are these hybrid or heirloom seeds?
This is an open-pollinated variety — not a hybrid — making it excellent for seed saving and producing consistent harvests year after year.
