In rainy or dewy weather, the fruit is not picked until the plants are dry. Berries that are already wet need to be lightly dried in the sun. The fruits are usually picked from the plants by hand every 2 to 3 weeks, although some growers prefer to shake the plants and gather the fallen fruits from the ground in order to obtain those of more uniform maturity. At the peak of the season, a worker can pick 2 1/2 bushels (90 liters) a day, but at the beginning and end of the season, when the crop is light, only 1/2 bushel (18 liters).
