Product Details:

Overwinter Japanese Onion Seeds offer you the opportunity to cultivate resilient and flavorful onions that thrive through all seasons. These onions, reaching a mature height of 12-18 inches, are perfect for fresh use, cooking, and long-term storage. Their ability to withstand colder temperatures makes them an excellent choice for overwintering, ensuring a continuous supply of delicious onions.

Planting Instructions:

Seed Preparation:

Soak seeds in lukewarm water for 12-24 hours to improve germination rates.

Dry the seeds thoroughly before sowing.

Sowing:

Sow seeds directly outdoors in late summer or early fall for overwintering.

Plant seeds 1/4 inch deep in rows spaced 12-18 inches apart, with seeds spaced about 1 inch apart within the row.

Germination:

Keep the soil consistently moist but not waterlogged during germination, which typically takes 7-14 days.

Ensure the soil temperature is between 50-75°F (10-24°C) for optimal germination.

Transplanting:

If starting seeds indoors, transplant seedlings outdoors when they are about 3-4 inches tall and have several true leaves, spacing them 4-6 inches apart.

Transplant in late fall to allow the onions to establish before winter.

Care and Maintenance:

Water regularly to keep the soil evenly moist, especially during dry spells.

Mulch around the plants to retain moisture, suppress weeds, and protect from extreme temperatures.

Thin seedlings to ensure adequate space for bulb development, maintaining a spacing of 4-6 inches between plants.

Happy Gardening!
