how are oranges harvested?
Navel oranges ripen in the winter and into the spring and early summer, while Valencia oranges begin ripening in the spring and are harvested through the summer. Mandarin Mandarins are more tolerant of cooler temperatures than are many varieties of sweet orange, and they require only moderate heat to ripen well, making them, along with lemons and limes, well suited to northern climates and cool coastal locales.
