Frequently Asked Questions


How do I manage onion (Allium cepa) downy mildew or purple blotch if my plants get leaf spots in humid weather?
Watch for grayish/purple lesions on leaves and a fuzzy look from downy mildew, especially after cool, humid nights. Improve airflow by thinning so bulbs have space, water at the soil line (not the leaves), and remove badly infected leaves. If it keeps spreading, use a labeled fungicide for onions and follow the label timing closely, since fungal pressure can return quickly in wet spells.
How often should I water Allium cepa during the main bulb-growing phase?
During active leaf and bulb growth, keep the soil evenly moist but not soggy—aim for about 1 inch of water per week, split into 2–3 waterings if you’re getting less rainfall. Let the top 1 inch of soil dry slightly between waterings, because waterlogged soil reduces bulb formation and increases disease. Once bulbs start enlarging and tops are mostly standing, gradually reduce watering to prevent rot and to help bulbs cure.
When are Allium cepa bulbs ready to harvest, and how can I tell?
Harvest when most tops have fallen over and the outer skins are dry and papery, typically around 120 days. Gently lift a bulb: if the neck is tightened and the bulb has a firm, well-developed shape with fully colored outer layers, it’s ready. Don’t leave bulbs in wet soil after the tops flop—harvest promptly to avoid soft rot.

Sweetly pungent and richly red from shoulder to stem, Yadkin Valley Red forms handsome, globe-leaning bulbs with a satiny skin that deepens to garnet as it matures. The flesh is crisp and juicy, balancing mild sweetness with a savory edge—ideal for bold, colorful roasts, caramelizing, and vibrant fresh slices in salads, as well as striking color in sauces and pickles.

Sowing Tips

Transplant Conditions

Wait until soil reaches 45°F and nights stay above 28°F before moving outdoors.

Expert Note

Plant multiplier (potato) onions as soon as soil is workable so the new bulbs form before peak summer heat.
