my grapefruit tree leaves turn yellow with brown marks

Question

My grapefruit tree leaves turn yellow with brown marks. It is not very young tree, but we never have a lot of fruit from it. There’s always something wrong – yellow leaves, small fruit, etc.

Answer 1

With the history of poor performance with your tree, I would highly recommend a soil test. You then can determine the correct fertilizing schedule.
