Q.

storing onions

Zone 84042 | Anonymous added on November 17, 2017 | Answered

My onions are stored in a cool garage but some of them continue to grow sprouts. Is this caused by temperature, humidity, or light? If they were not cured sufficiently, what should I do now?

Lack of proper curing typically leads to mold growth on onions. Humidity and temperature can contribute to sprouting- 32-40 degrees, humidity of 65-70%, and darkness are ideal conditions. The closer you can come to that, the less likely they will be to sprout.
