Planting & Care

Start Texas Grano 502 onion seeds indoors 8-10 weeks before the last expected frost, or sow directly in the garden in fall in mild climates. Plant seeds 1/4 inch deep in a well-drained seed-starting mix or garden soil. Keep the soil consistently moist but not waterlogged during germination. Once seedlings are sturdy, harden them off and transplant to the garden, spacing them 4-6 inches apart.

Onions require regular watering and benefit from a balanced fertilizer applied according to soil test recommendations. Keep the area weed-free to reduce competition. Stop watering when tops begin to fall over, and harvest after the necks dry and tops yellow. Cure bulbs in a warm, dry, well-ventilated area before storing.
