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?
