Bud-Pruning Not Beneficial for Virginia Pine
Trees of Pinus virginiana, Mill., originally two to five feet tall, were bud-pruned and thinned for six consecutive years. Thinning increased growth and did not ineract with pruning. Bud-pruning was found to: (1) eliminate knots, (2) cause severe deformity in 57 percent of the stems, (3) reduce height growth 25 percent, diameter growth 63 percent, and (4) cost more than conventional pruning. Results are consistent with literature on nine other North American conifers.
