Growing pomegranate tree

I have started to grow pomegranate trees and need to know what nees to be done in order to grow them in containers.

They want well-draining soil, lots of sun, and infrequent watering. Make sure to bring the pot inside in the winter. Bring it inside during any late frost events. Late frosts can kill poms around here.

If you want them to bear fruit, they need regular watering
and feeding.

Do they grow ok in zones 7a- 8b ? i ordered some and want to grow them right
