This is my own mature Canary Island date palm in Old Escondido. I began watching it closely after someone suggested it might be affected by South American palm weevil.
The palm has been treated twice, and I have caught adult palm weevils on or around it. I am not calling it cured, saved, doomed, or beyond help.
The crown has shown decline, but the palm has not rapidly collapsed. It has looked relatively stable for months. That makes repeat photographs more useful than a dramatic conclusion based on one day.
I am continuing to treat, watch, and compare it. This is the kind of uncertainty owners of mature palms actually have to manage: act on the risk without pretending to know an outcome that has not happened.
