Any thoughts on what is going on here or how to fix it?

All of the fruit on Panache are dropping or rotting in the tree before anywhere near ripening.

It's been fairly dry with the tree growing in a 5 gallon sip outside with about 6 hours of sun a day and not overly crowded. The tree looks healthy otherwise. Haven't noticed any odd bugs in or on the tree / fruit.

Attached are pics of two.

Thanks for any help.

Panache is not easy to ripe in cold climate.
If certain cultivars do not have the right climate,with enough sun exposure, or growing in pot,is not what they like,then they will abort fruits before properly ripe.
Those fruits are in  that situation and in my opinion aborted.
Sorry for bad news!

Thanks for the response. Maybe I'll have to see if I can get it into more light next year. There are only about 2 of 10 still in the tree at this point.

A short period of high heat nd drought stress can do that in my experience.
