Pollination occurs best at a specific temperature and humidity. In California, our flowering starts early and lasts for a prolonged time period up to 6 months or more. This year, flowering started for me around November and I still have blooms on my E4 right now.
When the pollination occurs outside of the ideal range, it can cause the pollen to be sterile or cause incomplete pollination. I hypothesized that this is just one of the reasons I get so many nubbins Which incidentally have aborted or tiny seeds.
I don’t strip my early blooms because it may cause excess bloom cycles which may waste more of the trees energy. I sometimes strip the second to last predicted blooms. The blooms in the warmer weather have set the best fruit for me but I also have a lot of fungal issues.
