Kevin,
Last year was my 2nd year of Sugar Cane and Shanxi li. Shanxi did not flowered much. SC had no pollination partner. Honey Jar was new (a replacement). I may have fewer than ten fruit all together.
What a different this year. HJ is 2nd year and full of flowers. SC 3 yrs old) has flowered so prolifically. Shanxi li (3 yrs old) is producing 1/2 of the flowers SC is producing. I also have So and Massandra in pots, which I conveniently set them next to HJ and SC. In addition, my this yearâs grafts of Autum Beauty, Jin and Dong Zao also have flowered. I think they all help with cross pollination.
I also have seen small flying insects ( flies?) in addition to bees and wasps. So far, so good. There are a lot of fruit set on HJ and SC and some on So and Shanxi.
@scottfsmith, I am surprised that your 3 yrs old does not set fruit this year.
