I have a Desert Willow that is showing stress. Many branches have leaves which are Browning from the tips. This was sudden. A week ago it was all green and blooming. There are still some branches with bright green leaves but I am afraid these might end up the same. I suspect salt contamination or Texas Root rot. Any other thoughts? The Desert Willow is a hardy plant and I am stumped.
