Since I did not make the drive up or down the coast very often, the rare silvery-gray Bismarck palm that I could see slowly climbing into the skyline near the edge of Highway 101 through Santa Barbara seemed to be slightly taller every time I saw it. It grew slowly, but enough to notice since I only saw it less than annually. Then, when I drove by about a month ago, it was gone.
This exemplary specimen had been quite healthy and happy (even though Bismarck palms are not supposed to be happy on the coast). There was only one problem. It was under high voltage utility cables. As it grew, it got too close to the cables, so needed to be removed in order to maintain the minimal clearance required for high voltage.
Unlike other trees, palms have only single terminal buds that grow upward. They can not develop branches to grow around cables, so only die if the single bud needs to be pruned away. Complete removal is therefore the only option when palms begin to grow into high voltage cables.
Sadly, palms often get planted under utility cables. Many Mexican fan palms grow under cables because birds that eat their fruit drop the seed there. Queen palms are popularly planted around the perimeters of back yards, and along the back fence lines that are very often directly below and parallel to high voltage cables.
Trees that are not palms can get disfigured by pruning for clearance around high voltage cables, but generally survive. Trees with central leaders (single trunks) and strict form, such as spruces and redwoods, can get be so disfigured that removal may be more practical than pruning. Trees with more irregular form, like sycamores and elms, are somewhat easier to salvage. Unfortunately, crews hired to maintain clearance are unable to prioritize the health and structure of trees that get too close to high voltage cables.
Lower cables for telephone, television and house-drops (lower voltage cables that extend from utility poles to homes and other buildings) do not often justify pruning for clearance like upper high voltage cables do. However, these lower priority cables can still be damaged if too many limbs sag onto them or become abrasive as they blow in the wind. Really, it is best to avoid problems with utility cables by selecting and planting trees that are not likely to become too obtrusive. Palms, large trees and trees that are likely to be severely disfigured by pruning to maintain clearance should be kept at safe distances.
B & B, formally known as ‘balled and burlapped’ nursery stock, was expected to be the next big ‘thing’ in nursery commodities here in California back in the late 1980s. As those outside of California know, it is field grown plant material that gets dug and marketed with its roots wrapped in burlap. It was more common in other regions, so was expected to become more common here as more nursery stock was to be imported from Oregon.
This is no common Douglas fir. It is the ‘Davey Tree’, named after the tree service that so diligently prunes it for clearance from the utility cables above. Yes, I can see as easily as you can how disfigured it is. The plan is to cut it down before it falls apart. At least that is the excuse for cutting it down. It is relatively short an stout, so is likely quite able to support its own weight, regardless of this disfigurement. We really just want it gone because it is so unsightly.
There is no sugaring season here. Spring comes on too suddenly. By the time sap starts to flow, buds are already swelling.
This is why I do not grow hellebores in my own garden. The specimen in the pictures above and below are about as good as they get here. Most are quite a bit worse. Some put out only one or two flowers. Some do not survive their first year in the garden.
