Jiro ripened almost a dozen last year. Unfortunately not one of them was sweet enough: they were all too bland in flavor.
One of my friends also grew it and he said that 2015 and 2016 were good years but 2017, it wasnt hot enough to ripen fruit well. So, I don’t think it is a suitable variety for our area.
My neighbor down the street is growing Izu and it ripens well each year. Last year’s fruit was very good. I would recommend that instead.
