onion

Onion - Planting: Start seedlings indoors 4-6 weeks before transplanting. Sow seeds in flats ¼" deep and spaced 1" in all directions. Transplant as soon as the soil can be worked in the spring.

Seed Saving: Biennial. Onions cross-pollinate and should be isolated by 1 mile from other onions going to seed. Select only the best bulbs for seed. Bulbs store 3-6 months at 32-45° F. Plant out bulbs in early spring and allow them to form seed heads. When the heads start to dry, cut off, dry further and thresh.
