Know before you buy
No, these are best enjoyed fresh. Because they are a sweet, high-moisture variety, they have a shorter shelf life compared to pungent storage onions and should be consumed shortly after harvest.
Long-day onions require 14 to 16 hours of daylight to trigger bulb formation. They are specifically suited for northern regions where summer days provide the necessary light duration for the bulbs to reach their full size.
For optimal bulb development, thin your plants to 2–7 inches apart. Ensure your rows are spaced 12–24 inches apart to allow for proper airflow and root expansion.
Yes, these are open-pollinated plants, which means you can collect and save the seeds from your harvest to replant in future seasons. They will grow true to type, provided they haven't cross-pollinated with other onion varieties in your garden.
Since these plants are shipped hardened-off, they are ready to go into the ground immediately. Maintain consistent, moderate watering throughout the growing season and apply a medium amount of fertilizer to support healthy bulb development.
