Blackberry Not Setting Fruits
I've had this Black Satin blackberry for 10 years. But I do not remember it ever setting any berry fruits. It gets 80% sun, in a grass area, but mostly not having grass at its foot. I do not spend much time with the plant and it still come up every year.
As far I can remember, the plant grows to about 2-3 feet, to about 4-5 feet large. It flowers, and appears to set fruits, but the fruits never materialize.
I do not know what to do with it. I do not think it needs any pollination. Close by, we have a lot of wild raspberry bushes.
