When and Where to Plant

The Tokyo Long White Bunching Onion grows best in full sun and well-drained soil. You should start planting them in early spring, about 4-6 weeks before the last frost date in your area. You can also grow in the fall for a winter harvest in regions with mild winters.

Starting Seeds Indoors vs. Direct Sowing

You can start bunching onion seeds indoors or directly sow them in your garden. If you start seeds indoors, do so 4-6 weeks before your last frost date. This gives the plants a head start and helps ensure a successful growing season. Transplant the seedlings outdoors when about 2-3 inches tall after the last frost.

Direct sowing works well, too, especially if you want a continuous harvest throughout the growing season. Sow seeds into the garden in early spring once the soil has warmed up and can be worked easily.

Preparing Your Soil

Tokyo Long White Bunching Onions thrive in well-drained soil with a pH between 6.0 and 7.0. Before planting, work some compost or well-aged manure into the ground to improve its fertility and drainage. Ensure that the planting area receives full sun for your onions' best growth and development.

Planting and Growing Tips 

To plant your Tokyo Long White Bunching Onion seeds, follow these steps:
  1. Create shallow furrows in the soil, about 1/4 to 1/2 inch deep.
  2. Sow seeds about 2-3 inches apart in the trenches, ensuring adequate space for the onions to grow.
  3. Cover the bases with a thin layer of soil and gently pat them down.
  4. Water the area thoroughly, providing the soil remains moist until the seeds germinate.

Caring for Your Growing Onions

Proper care is crucial for a successful Tokyo Long White Bunching Onions harvest. Here are some tips to ensure healthy growth:

  • Watering: Keep the soil consistently moist, especially during dry spells. Be careful not to overwater, as this can lead to root rot.
  • Fertilizing: Apply a balanced, slow-release fertilizer at planting time and side-dress with additional fertilizer midway through the growing season to promote healthy growth.
  • Weeding: Remove weeds regularly to reduce competition for nutrients and water. Be gentle when weeding, as onion roots are shallow and easily damaged.
  • Thinning: If your onion plants appear overcrowded, thin them out to ensure proper spacing and airflow.

Harvesting and Storing

You can start harvesting Tokyo Long White Bunching Onions when they reach 12-18 inches in height and have a diameter of about 1/2 inch at the base. Gently pull the onions from the ground, careful not to damage the green tops. If you prefer a milder flavor, harvest your onions when they are younger and smaller.

To store your harvested onions, trim the green tops and clean off any soil. Store them in a cool, dark place with good air circulation, such as a pantry or cellar. You can also chop the onions and freeze them later in your favorite recipes.

Conclusion

Growing Tokyo Long White Bunching Onions is a rewarding experience that adds a delicious, mild flavor to your culinary creations. Following this step-by-step guide will make you well on your way to a successful harvest. Enjoy the process and the tasty results of your gardening efforts!
