Full-Size Onions

Onions receive their cue to start bulbing from day length. In order to grow onion plants that form full-size bulbs by harvest time, it is important to choose varieties that are best 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.


Johnnys is committed to your success and is with you every step of the way.
