Why is my blood orange producing only on the bottom third of tree? I have a blood orange tree, going into its 4th yr. It appears to be growing very nicely, approx. 8 ft tall now, and has nice lush dark green foliage. In second year it gave about 6-7 nice oranges. Last year (3rd) it produced approx. 2 dozen nice oranges but they mostly were in the bottom third of the tree. This year, the blossoms are again in the same location. They are evenly dispersed throughout the tree. Am I expecting too much too soon or is there a reason why this is occurring? I water it pretty well about twice a week and fertilize it every 3-4 months with a commercial citrus/avocado fertilizer.
