Frequently Asked Questions

What pest or disease most often affects Allium cepa (onions) and how do I manage it at home?

Onions are frequently hit by onion thrips, which cause silvery streaks and distorted, stunted leaves. Use yellow sticky traps plus weekly checks, then spray a solution of insecticidal soap targeted to the leaf undersides when thrips are active. Keep onion beds well weeded and avoid overhead watering to reduce disease pressure like botrytis/leaf blight.

How often should I water Allium cepa during the main bulbing growth phase?

During bulbing (roughly mid-season until the tops start to tip), water deeply enough to keep the soil consistently moist but never waterlogged—typically about 1 inch (2.5 cm) per week depending on heat and soil. Let the top couple centimeters of soil dry slightly between waterings, because soggy soil around the forming bulbs can lead to rot. When bulbs start to size and leaves begin slowing, gradually cut back watering.

How can I tell when Allium cepa is ready to harvest?

Harvest when about 50–70% of the tops have fallen over and the necks feel dry and tight rather than watery. The bulbs should have fully colored, papery skins, and you should be able to lift one and see its mature size without the neck staying soft. Plan harvest on a dry day and cure bulbs out of direct sun with good airflow for 1–2 weeks before storing.

Sweet and clean from the first bite, Early White Grano forms crisp, ivory-white bulbs with a bright, juicy snap and a gently mild bite that feels almost luminous. At maturity, the globes hold a tidy, well-filled shape and roast up with a tender, mellow depth while staying pleasantly fresh for salads, relishes, and quick pickling. A dependable choice for gardeners seeking early-season satisfaction and beautiful white bulbs that store with confidence through the season.

Sowing Tips

Transplant Conditions

Wait until soil reaches 45°F and nights stay above 35°F before moving outdoors. Harden off for 7 days first.

Expert Note

Start indoors early if you can control light and temperatures; transplant only once nighttime temps are reliably above the onion’s cold limit and the soil is workable to prevent stunting.
