I have a 50 year old naval orange tree , they grow very large and sweet , about 15% of them get splits before ripening, could it be too much or too little water?

Thank you for your question about the splitting of your navel orange. UCal Extension has a great article explaining the many reasons for this, and you can read about them and potential solutions on page 2. I hope this is helpful to you. Good luck!
