I understand that fruit can get sent by air all the way from Chile to the United States when it is winter in the U.S. But even within the Northern or Southern hemisphere, it seems that harvest season is going to vary by latitude. So, the regions in which cherries, or apples, or tomatoes, etc. are ready for picking will continuously vary every week. How can grocery store suppliers constantly vary where they source their ripe fruit every single week of the year? How can they have relationships with so many farmers in so many regions and even countries? Is there a website farmers can use to tell suppliers all over the world when their fruits are ripe?
