Sow indoors in flats with good potting soil February to March. Transplant into the garden in April or May, when plants are at least the size of a pencil lead. Space 6” in rows that are 1’ apart. Onions benefit from frequent watering and shallow cultivation. Harvest when stem has shriveled and tipped over.
To save seed, replant at least 20 onions in the second spring. Large, beautiful globe shaped flower stalks attract pollinators. Isolate from other onions by at least ½ mile.
