Pygmy Date Palm
My pygmy date palm is 4 years old, about 6 ft tall. It has four trunks. One of the trunks is turning brown. The others are fine. I don't see any bugs or fungus. I live in AZ, 112 degrees today. It gets plenty of water. What can I do or look for?

Apply a fungicide to see if this helps. Otherwise, you may need to prune off the browned trunk.
