SPRING SWEET ONIONS (Monday, May 24): Hey, the National Geographic Finals are this week in Washington, D.C., so I thought it’d be a little fun – let’s have a geography lesson. Let’s see - What doesWalla Walla, Vidalia, Maui, and Imperial Valley all have in common? They all grow onions. They all grow spring sweet onions. In fact, this is spring sweet onion time and we’re starting to see some beautiful Vidalia onions, Texas 1015Y and Imperial Sweets. Maui Onions are generally available year-round.
