I don't see the need to abandon groves and fail to understand why this occurs. Yes there is a major economic setback for the grower but They already own the land, most of the equipment remains the same, grow something else. If one is north of Orlando or in an area like mine, apples grow grow great, and require less care than oranges and produce better at a smaller size. South of Orlando, Olives, lychee, and numerous other warm weather loving trees. Last I checked 55 gallon drums of olive oil were selling for quite a bit. Olives take almost zero care, hell, my trees thrive on being ignored. Pomegranates do great here and with the health food craze all they need is creative marketing. All it takes is the farmer leaving their comfort zone, putting up with a few years of loss, which they are going to get anyway since they just abandoned their grove. We have the space, we have the infrastructure, quit gloom and dooming, suck it up, and try something else.
