Long-Day Onion Plants initiate the bulbing process when daylight reaches 14-16 hours, making them particularly well-suited for northern states where they grow best. Available in sweet, storage, and specialty varieties, these onions offer excellent storage capabilities, making them ideal for long-term use. Thriving in latitudes between 37 and 47, Long-Day Onions are an excellent choice for growers in northern regions seeking high-quality, long-lasting onions.
