The article reports that grape vines in San Joaquin Valley, California are likely to suffer from spring fever should weather forecasts of alternating periods of cold and warm temperatures materialize. Spring fever is a weather-related disorder characterized by chlorotic leaves whose green color fades first from the margins and onto the inward area. The symptoms exhibited by grape vines suffering from spring fever are similar to those shown by plants suffering from potassium deficiency.
