These are overwintering varieties intended for autumn planting.
Yes, they perform well in containers provided the soil is well-draining and the pots have adequate drainage holes.
Each plant has a 15cm spread, so space them at least 15cm apart to ensure proper airflow.
You can typically harvest these onions between May and June.
Keep them in a cool, dark, and well-ventilated location, ensuring they stay dry and away from pests.
The mix includes Red Winter and Electric, both of which are excellent for overwintering.
The soil likely lacks proper drainage; consider mounding the soil or using containers with gravel at the base for better water movement.
Storage temperature is too high or humidity is too present; move them to a cooler, darker, and more ventilated storage location.
Check for weed competition and ensure the plants are receiving full sun exposure as the days lengthen.
Before planting, ensure your onion sets are stored in a cool, dark, and well-ventilated area. Avoid areas with high humidity to prevent premature sprouting or mold. When ready to plant, choose a location with full sun exposure. Bury the bulbs so that the tip is just visible above the soil line, spacing them appropriately to accommodate their 15cm spread. If using containers, ensure they have drainage holes at the base. Keep the area around the bulbs weed-free to reduce competition for nutrients.
