Why doesn’t my winterberry have berries?

How close does a male winterberry need to be to a female?
40 to 50 feet
To ensure pollination, a male winterberry holly must be planted within 40 to 50 feet of a female winterberry holly. Because some males are early blooming and others are late blooming, the appropriate male must be in bloom at the same time as the female.
