Increasing pomegranate production with second tree

Question

We have a single pomegranate tree we planted recently. We’ve read that adding a second can greatly increase your harvest. I assume this means more than just accounting for the extra tree.

How does adding a second tree increase fruit production more than just having a second tree? If this is related to generic diversity, does it matter if the second tree is cloned by rooting a cutting from the first tree? Should our second tree be from a garden center instead, or are these typically propagated by rooting cuttings anyway?

Answer 1

Typically, if the second tree is not an exact clone of the first, better pollination, even with "self-pollinating" fruit types. Cloned is fine, but get a clone of another variety of pomegranate, not the same one you have now.
