Frequently Asked Questions

What pest or disease most commonly affects Allium fistulosum (bunching onions), and what should I do?

Look for onion fly maggots (often causing wilting and hollowed bases) and for downy mildew when nights are cool and leaves stay damp. Cover seedlings with a fine insect net to block onion flies, and remove any plants that collapse from the base. For downy mildew, water at the soil line (not the leaves), improve airflow between rows, and remove infected foliage promptly to slow spread.

How often should I water Tokyo Long White bunching onions during the main growing phase?

During the 45–60 day push of leaf growth, keep the top 1–2 inches of soil consistently moist but not waterlogged. In typical home gardens this is often about 1 inch of water per week, split into smaller soakings if it’s very hot or windy. If the soil dries deeper than 2 inches, the plants can turn tough and slow down, so check by feel before each watering.

How do I tell when Allium fistulosum (Tokyo Long White) is ready to harvest?

Harvest at about 60 days when plants form a thick, white “shank” and the leaves are long and still firm (not collapsing). You can harvest in bunches by pulling or cutting close to the soil; the longer you wait beyond this, the more likely the flavor becomes sharper and the texture tougher. If you want the longest white portion, keep the base slightly protected from light during growth (e.g., gentle soil hilling or snug soil/compost around the stems).
