Orange Tree Leaf Drop, AZ
So I have what I think is a dwarf orange tree. Im not sure how old, but I can tell you it is 9 feet tall, with an 8 foot canopy, and bears fruit.
This May, I noticed that leaves had begun to drop off. It went through a normal bloom, and has some fruit on it now. I give it 7.5 gallons of water over the course of 1 hour every three days. I just upped that from every 4 days since it started getting hotter.
After reading around here, it seems like I am giving too much water, but I wanted to confirm it since too little and too much water could cause the leaf drop. But the most recent change I made that correlates with the problem is the watering. Please let me know your thoughts. If it is too much water, is it too late to help the tree out? What is the best course of action now?
Also, I never fertilize this tree, although I have been noticing less fruit on it in recent years, so I was planning on doing it this year.
