Onion, Newburg (Organic)

Onion, Newburg (Organic)


Allium cepa. Yellow Storage. 110 days.

Newburg Onion is simply the best open pollinated yellow storage-onion and is one of Dr. Alan Kapuler’s incredible dehybridized gems.  Selected from a European commercial hybrid storage onion, it was reselected under and for organic production. The tightly wrapped, copper-skinned, spherical bulbs are known for their excellent storage life, crisp texture, and medium hot rich flavor. We thought it was named after the town of Newberg, Oregon, which is not true.  Newburg has out yielded hybrids when trialed under organic conditions, therefore it is a great replacement for the classic Hybrid Copra, which many people think will be dropped by its corporate owner.

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.
