I live in Western WA, and have had the worst year for making crosses. I blamed the heat, even though i as out there doing it around 5:30am most mornings. 90+ % failed. It has been cooler this week, i continued on making crosses. I won't know for another week or two if any are successful.
I've only been hybridizing for 4 years, but this is the worst year so far for making successful crosses.
