Q.Pomegranate Trees
I am growing two pomegranate trees in large containers. They are the dwarf variety. I get large orange flowers where the fruit is supposed to grow but the flowers fall off and no fruit grows. Is this the way it’s supposed to be? Also, the leaves are starting to turn a sort of copper color but are not falling off. Do they need a special kind of food? How often should I water these trees? I live in MT and bring the trees in the house in the winter.

This can usually be attributed to poor pollination. Both flowers and fruiting will not take place. Not all blossoms will produce fruit, but you can help encourage fruit production. Take a soft small paintbrush and brush the stamens of open blossoms from bloom to bloom.
They need regular weekly watering, saturating thoroughly (make sure there is good drainage). If temps climb above 80, you'll need to water every day.
