When farmers’ markets and grocery stores across the U.S. stock large quantities of watermelon, is there a juicier sign it’s summer?  With increasing regularity and creativity, watermelon dishes are popping up on drink and food menus at restaurants nationwide. The top four watermelon-growing states are Georgia, Florida, Texas, and California, according to the Agricultural Marketing Resource Center. Other states grow watermelons, too, so you might find a local supplier wherever you live. Only when the fruit vegetable isn’t in season is it imported from other countries to ensure that watermelon remains available year-round.
