P90303What makes this Bullwinkle worse than most is that I pruned it like this myself. What makes it worse than worse is that it did not need to be pruned in this disfiguring manner for clearance from utility cables like the last one I wrote about was. https://tonytomeo.com/2018/08/08/horridculture-bullwinkle/ It is instead an attempt to renovate an overgrown hedge that was behaving something like a fat hedge. https://tonytomeo.com/2018/06/06/horridculture-fat-hedges/

In fact, the only reason it did not qualify as a fat hedge is that it had plenty of space for all of its superfluous bulk The side to the left was only beginning to encroach into the driveway on that side, and was easily pruned back to the curb, which for now, is adequate confinement. The side on the right was only beginning to encroach into the upstairs balconies, and was likewise easily pruned back for reasonable clearance.

The problems with this hedge were within and on top. It had been shorn back only for minimal confinement for so long that all the foliage on the sides was within a thin external layer. Pruning any farther back would have exposed a thicket of necrotic stems in various degrees of deterioration that had been accumulating within the interior for many years. Almost all growth was directed to and concentrated on top, which shaded the interior and lower stems even more than the accumulation of necrotic crud within did. Since the top had always been pruned down to the same height, all subsequent growth after pruning on top was above where it had been pruned previously, which was of course above the height where it was wanted, and consequently removed when the hedge was pruned again. There was no incentive for lower foliage to develop.

The hedge is there to obscure the view of a building on the left from the windows of the building on the right. The most important foliage for that purpose is the lower foliage, which is precisely what is lacking. Almost all resources were going to the upper foliage, which was contributing nothing, while shading out the lower growth. Although the inner thicket of necrotic stems was partially helping to obscure the unwanted view, it was also inhibiting healthier lower growth.

The illustration shows what remains after the useless top and necrotic interior were removed. After the picture was taken, the left and right sides of the hedge were pruned lower to eliminate the useless upper foliage that was not contributing to the function of the hedge. As unsightly as it is, it partially obscures the view of the building on the left from the building on the right, and will obscure it more as new foliage develops. Now that the interior is exposed, new growth should develop within the interior, and lower to the ground. Because the area is partially shaded by nearby redwoods, the exposed interior limbs are not likely to be damaged by sun scald.

After the new interior growth is established and obscuring the view, the external sides that are there now can be pruned back farther and sloped inward toward the top so that the lower growth of the hedge gets more sunlight. The hedge certainly does not need to be as wide as it is. It would be easier to maintain if it were narrower and so close to the allowable boundaries. Ultimately, with appropriate pruning over the next few years, this old hedge should be restored.
