Keep early summer pruning to a minimum. Pruning in mid June to mid August has a stronger effect on tree vigor than later pruning (September), and response is less predictable. Pruning to expose fruit to light 3- 4 weeks before harvest is the most beneficial, and has less impact on the tree’s response.
