It’s 7 a.m. in Amado, Arizona, and the sun is rising over the greenhouses of Wholesum Harvest’s tomato farm. Workers trickle up the driveway in their cars. One by one, they hang their coats, wash up, and prepare to begin another hard day’s work. Potters enter the greenhouses to deleaf and prune tomato plants, carefully tending each pot’s liveliest flowers. Bio control teams divide and tackle insects and other pests that like to eat the tomatoes.
