Black Walnut Management

<<< prev      Contents      next >>> Clear-stem pruning develops knot-free lumber and veneer. Although you can begin when trees are only 12 feet tall, it's more efficient to prune trees that are 3 to 4 inches in stem diameter. Trees up to 10 inches in diameter may benefit from clear-stem pruning. Prune only 25 to 150 potential crop trees per acre. Select crop trees with straight stems, dominant leaders, average or larger stem diameters, small lateral branches, and no significant stem or branch damage. <<< prev      Contents      next >>>
