Interesting, Alan.
My 20 yr old Arizona Sweet orange didn't flower at all. My two next door neighbors tangerines/tangelos did flower. My Key Lime didn't. The new pomegranate came with flowers, fell off in time... I can't tell yet if fruit is set. I'm wondering in the citrus industry here in AZ was generally negatively affected as my trees, by the October hail and subsequent freeze.
Might need to consider buying orange juice futures.
