You need pollinator for good fruit set, .then you'll have lots of berries.

I got a real good deal at canadian tire $4 each.it seems that everything is already on clearance at my location.

Can you graft male to female plants? And wonder they probably graft dormant just like prunus?

I think so,..I grafted female onto female this spring and growing.

Did you get any berries on yours this year ?

The bush is about 7 foot tall but never has many berries...this should change with growing some males.
