Hi I have had this bonzai grape vine for 10 years. It had one bunch of grapes on it when I bought it but I have never gotten it to produce until this year. Last year I visited a winery and observed how they had their grapes set up and did the same to this one. My vine produced 10 bunches of grapes this spring. But now they seem to be turning to flowers. There are little stems with a pollen head on it around each grape. Do these drop off and still produce grapes? I am really thrilled to have gotten it to produce anything so if these drop off I will not be unhappy. The vine is about 3 feet long.
