Have they had berries before?
Shamrock is a female. There are no males in the trade as far as I can determine. I have 4 Shamrocks and zero berries for the three years I've had them. So they are not being pollinated by the American nor the Burford nearby. I'm really frustrated because I don't have room to buy seedlings are grow them up to find a male among them.
You'd go nuts trying to pick all the flowers off them.
They might never get berries. And if they do, would the dog be tempted to eat them? They're tiny, black, not very showy. Does the dog eat other stuff in the yard? Do you have azaleas? Those are said to be toxic as well.
