I keep finding split mandarins on my in-ground greenhouse trees. Only a small percentage of the crop, but enough I think it is a sign something needs correction. Am I right that this is caused by drought stress followed by watering? My trees are on drip irrigation that turns on for an hour every 3-4 days. I just guessed, maybe it isn't quite enough. The trees have never showed any sign of wilting so I figured it was good.
