Frequently Asked Questions


What onion (Allium cepa) pest or disease should I watch for, and what should I do first?
Watch for onion maggots and downy mildew (a common Allium problem). For onion maggots, use floating row cover over seedlings and remove any infested plants promptly; for downy mildew, keep foliage dry with morning watering and improve airflow by spacing plants correctly, then remove affected leaves to slow spread. Avoid working in the bed when plants are wet to reduce disease transfer.
How often should I water Allium cepa during the main growing phase to keep bulbs developing well?
During active leaf growth and bulb swelling (roughly mid-season), water deeply about 1 inch per week, adjusting for heat—keep the soil consistently moist but not soggy. Let the top 1–2 inches of soil dry slightly between waterings to prevent bulb rot and disease buildup. Inconsistent watering can cause stunted or split bulbs at harvest.
How can I tell when Allium cepa ‘Red Creole’ is ready to harvest at home?
Harvest when about 1/2 to 2/3 of the plants have fallen over and the necks begin to soften, typically around 105 days from planting. Gently lift one bulb to confirm the bulb size and check that the outer skins are papery and colored. Stop watering as harvest approaches and cure bulbs in a warm, airy place out of direct sun for 1–2 weeks.
Botanical illustration of Red Creole

Sweetly aromatic and richly colored, Red Creole forms medium-large bulbs with a burnished red skin that deepens to a jewel tone as it matures. The flesh is crisp and juicy, balancing gentle sweetness with a lively allium bite—ideal for fresh use and for roasting until mellow and fragrant. Grow this intermediate-day onion for dependable harvests around 105 days, with bulbs that store with confidence and add striking color to every garden basket.

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

Transplant when seedlings are thick and about pencil-sized; consistent moisture and full sun are key for solid bulbs and storage quality.
