Answer
No pruning will not help the health of a tree. I woudl fertilize the tree. Growth can be accelerated with light frequent applications of fertilizer during the first three growing seasons. Measure an area three times the canopy spread, then broadcast one pound (2 cups) of 8-8-8 or 10-10-10 fertilizer per 100 square feet in March, May, July and September. By the fourth growing season, reduce the application frequency to once or twice a year.
