What causes June fruit drop?
June drop is more correctly called physiological fruit drop and is caused by a shortfall of carbohydrates in the tree. This shortfall is because the trees have limited leaf area for photosynthesis (supply of carbohydrates) but a lot of developing fruit all demanding carbohydrates to grow.
