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.

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.

Sowing Tips

Soil Temperature

Direct sow or transplant when soil at planting depth holds 45°F for reliable germination and early growth.

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.
