Full-Size Onions
Onions receive their cue to start bulbing from day length, and to grow onion plants that form full-size bulbs by harvest time it is important to choose varieties adapted to the maximum growing season of day length in your region. Johnny's offers a selection of full-size onions varieties for each of the three day-length adaptations: long-day, intermediate-day, and short-day. Use our Full-Size Onion Comparison Chart to select the best varieties for your region, and to compare bulb size, color, shape, adaptability, storage potential, and other distinguishing characteristics.
