Hi SW peeps!

Hope all is well with you. This winter I notice one of my bottle trees is having a terrible time. I don't understand why as it's sister tree planted just feet away is doing great. Every research I've done talks about lack of water as being the main culprit for the bottle tree (not bottlebrush), but they are both at least 10-12 yrs old and get the same sun/wind/rain/frost exposure for the most part.

Any ideas what might be the trouble? It put out its normal seed pods last summer.... I have no idea what might have happened..

Thanks for any input. I appreciate it.
