The picture shows that in order to screen the wires, you need some 30' height (at maturity) material. How plants are arranged is difficult to tell from the picture and many things mentioned are not visible. It would be easier to discern the layout from an accurate scale plan view. I suspect you might need to replace the Forsythia hedge with the taller material.

Ohh gosh - yea I'm lucky I was able to upload this pic - don't think I can handle multiple in one post. I'm pretty bad with technology. :-(
In any case, the adjacent sides are fence lined with the assorted plant material I mentioned beforehand but I don't necessarily have to repeat them. I know I have to remove some of the forsythia and get some very tall evergreens back there as well. I guess what I am looking for is a fresh set of eyes to point out anything I might have overlooked. In the meantime, if you have any ideas about a different layout or evergreen grouping - let me know. Thx again for replying.

I would consider beefing up the 'October glory' by adding 2 more, one placed to each side and behind, in a triangular fashion. and then adding evergreen in lieu of where the remaining forsythia is, in a double staggered row, if you wish to have it look full, but not rigidly formal. You could use a single variety of evergreen, or groups (not individuals) of different varieties, depending on what kind of "look" you're trying to achieve. I don't think it's critical that you use evergreen as deciduous will work well to camouflage the wires so that they are not disturbing.

Thanks so much! In the spring I will incorporate those insights!
