My gardener pruned my Pistachio tree in December/January and it continues to look bare. Can it be that the tree was overpruned?

Overpruning may not kill a tree directly, but over time, the tree usually suffers from disease, weak structure, etc., and succombs. Never prune more than one-third of the canopy at one time.
