When it comes to peach and nectarine trees, bigger isn't necessarily better. An orchard worker can spend as much as half of his or her day lugging around the ladders required to reach the branches of a typical 13-foot tree. Plus, the danger of climbing the ladders drives up the cost of workers' compensation insurance—growers of peaches and nectarines pay about 40 percent more for it than growers of low-lying fruit like grapes.
Now scientists at the University of California are trying to shrink the cost of labor on peach and nectarine farms by shrinking the plants themselves. In a 4-acre orchard south of Fresno, researchers are growing trees that they expect to max out at seven or eight feet. They say the shorter trees, which would not require a ladder to harvest or prune, could cut down on worker injuries and slash labor costs by more than 50 percent. If cultivated correctly, the mini-trees could be as fruitful as their taller counterparts.
If the experimental orchard works, it could have environmental perks too. In comments to UC Davis, one farmer estimated it costs him $1,400 an acre to thin his 250-acre peach and nectarine farm. Because of the high cost of ladders, many of his fellow growers are switching to almonds, he said. And almonds, as we've said before, are sucking California dry.
