Hello,

Removing a dead frond on my Cuban unveiled a possible pink rot issue. I am in Santa Ana, CA.

is anyone able to confirm if pink rot and what I should do?

Does it smell? If not, it looks normal to me.

Looks like you had to “tear” the boot off instead of it coming off easily based on the vertical tares on the trunk. Some pink rot is not unusual inside old boots and usually isn’t a big concern unless it’s allowed to enter tender tissue. I’m not sure, from the photo, if that’s pink rot or just exposed tissue coloring though. To be safe, I’d spray that area of the trunk with an anti-fungal. 

I agree with Jim on that. Pink rod is usually floating around, however, is generally only a problem if it gets in an open wound. I know it’s always tempting to remove old leaf bases, but better to avoid if you can.

Thank you @Jim in Los Altos I did unfortunately cut it out. The frond was mostly dead and when pulling off there was a tiny bit still fresh. I did spray with fungicide to be safe. 

I have some possible pink rot on one of my Archontophoenix cunninghamiana trunks. I noticed it when watering an orchid I have attached to it's trunk. Does this look like pink rot?

It doesn’t look great Tracy, although I wouldn’t have thought that pink rot would be problematic in the woody parts. (Seems like it’s there much of the time). I could be wrong in that assumption though. The only palm I’d ever lost to the rot was a young royal that was injured after a freeze, and then became infected in the growing point.
