Sweet Spanish Onion Planting Instructions:
1. When to Plant: Start seeds indoors 8-12 weeks before the last frost. In milder climates, they can be sown outdoors in early spring as soon as the soil can be worked.
2. Preparation: Onions need loose, well-drained soil rich in nitrogen. Incorporate plenty of organic matter or aged compost into the bed before planting.
3. Sowing: Sow seeds 1/4 inch deep in flats. Keep the soil moist and provide plenty of light. When seedlings reach 5 inches tall, trim the tops to 3 inches to encourage strong root development.
4. Care: Onions have shallow roots and hate competing with weeds. Keep the bed clean and water consistently—at least 1 inch per week. As the bulbs begin to "shoulder" out of the ground, do not cover them with soil.
5. Pests and Diseases: Keep an eye out for Onion Maggots. Planting radishes nearby can act as a trap crop. To prevent neck rot during storage, ensure the onions are fully cured in a dry, shaded area with good airflow for 2-3 weeks after harvest.
