Frequently Asked Questions
What common problem affects Allium cepa (onion) and what should I do for it?
One frequent issue is onion thrips, which cause silvery streaks on leaves and can stunt bulbs if unmanaged. Check plants weekly by tapping foliage over white paper and treat early with insecticidal soap (especially on the undersides) and remove any badly affected leaves. If the problem persists, rotate controls and avoid repeated broad-spectrum sprays that can flare secondary pests.
How often should I water Allium cepa during the main growing phase?
During active leaf and bulb growth, keep soil evenly moist but not waterlogged—about 1 inch (2.5 cm) per week total, adjusted for rainfall and heat. Water deeply 1–2 times per week so moisture reaches the root zone, then let the top few centimeters dry slightly between waterings. When bulbs start enlarging, reduce watering to avoid cracked or soft bulbs.
How can I tell when Allium cepa is ready to harvest?
Harvest when about 50–75% of tops have fallen over and the remaining leaves are mostly dry, typically around the 105-day mark for this crop. Lift bulbs with a fork and gently cure them in a warm, airy spot out of direct rain for 1–2 weeks until skins are papery. If you can’t wait, onions harvested before full top fall should be used sooner because they store less well.
