Showing how to disbud shoots of some coniferous trees. Picking out the terminal bud A in spring usually causes both the ad- jacent lateral buds to develop. 425. Pruning for Density applies either to increasing or decreasing the density of the head. In ornamental and shade trees, a compact head is often desirable, while in fruit trees, a head that ad- mits abundant light and air (Pig. 164) is important (243). To increase density, encourage lateral branching by pinching all the more prominent terminal grow- ing points (Fig. 162). In some coniferous trees, as the Norway spruce,* dis- budding of the terminal shoots (Fig. 161) in spring is advisable, and in woody plants too tall for pinching, the more prominent terminal growing- points may be cut back with the pole shears (431), which causes the head to grow more dense. In pruning to form an open head (Fig. 164), it is wiser, as a rule, to thin out the smaller branches at some dis- tance from the trunk than to re- sit!r;f"^growtris^ prlotTd ^ovc large branches at their (right-hand side) by persistent union with the trunk. pinching of the terminal grow- -~^ r. • j^ ci.
