Frequently Asked Questions

How do I manage onion (Allium cepa) downy mildew or purple blotch during cool, wet weather?

Look for gray-purple blotches on leaves and a fuzzy downy growth during humid conditions, especially when plants are crowded. Remove and destroy heavily affected leaves, improve airflow by spacing and thinning, and avoid watering the foliage—water at the base early in the day. If outbreaks persist, use a labeled fungicide suitable for onions and follow the interval on the label.

How often should I water Allium cepa during the main growing phase to form good bulbs?

During active leaf growth and until bulbing starts, keep the soil evenly moist but not waterlogged—about 1 inch (2.5 cm) of water per week, adjusted for rainfall and heat. When bulbs begin to size, taper to lighter, less frequent watering so skins can mature; stop frequent watering once tops start to fall over. Check moisture 2–3 inches down—if it’s dry at that depth, irrigate; if it stays wet, hold off.

When is Ebenezer White onion (Allium cepa) ready to harvest and how can I tell?

Harvest when about half the tops have fallen over and the necks start to soften, typically around 110 days from sowing/transplanting depending on conditions. The bulbs should have fully colored skins (for white onions, tight, crisp outer layers) and feel firm rather than squishy. Lift carefully on a dry day, cure them in a shaded, airy spot for about 2 weeks, and then trim roots and tops for storage.

Sweetly mild and cleanly aromatic, Ebenezer White forms crisp, ivory-skinned bulbs with a bright, paper-white sheen that feels almost luminous in the hand. The flesh is tender yet firm, offering a juicy bite and a balanced flavor that shines in long-storing favorites—ideal for roasting, fresh slicing, and silky sauces, as well as pickling for a delicate tang.

Sowing Tips

Transplant Conditions

Wait until soil reaches 45°F and nights stay above 28°F before moving outdoors. Harden off for 5 days first.

Expert Note

For best long storage, grow bulbs in full sun and avoid overwatering after bulbs begin to size; cure harvested onions thoroughly until skins are papery.
