Onions

Can I grow Vidalia onions in Mississippi?

To be named Vidalia onions, they must be grown within 75 miles of Vidalia, Georgia, by federal law. However, sweet onions can be grown in Mississippi, which are just as good as Vidalia onions. Three keys to sweet onions are variety, soils, and stress.

The pungency in onions is governed by sulfur containing compounds:

1) Growing a variety of onion which does not accumulate sulfur such as grano or granex types.

2 )Growing onions on soils which are low in sulfur.

3) Allowing the onions to be stressed for water or nutrients during the growing season will produce a sweet onion.
