Junipers will not regrow from the brown (needle-less) sections. My personal opinion - those are an eyesore and cannot easily be improved. Remove them and replace with something more likely to stay in bounds, or something easier to keep within bounds via trimming, or something that can be rejuvenated (cut to the ground to produce all new growth) if it becomes too large.

Ditto.

However, if you like junipers, you can keep them trimmed but you have to do it every year, by cutting back only a bit so that there are still viable buds in the branches that you leave. As noted, once you leave it this long, you are out of luck.

Those turned out really nice. The previous owners were an older couple and we have kept them trimmed to where they are since we moved in, but I think we would regain quite a bit of our yard if they were not there. Our other concern is coyotes and other animals may hide in there and our oldest son is constantly digging lost balls out of the bushes, makes me a little nervous.

Nice job!

The opposite of a nice job. A few weeks ago I decided to thrash this thing to be able to pull into the garage. It is also an experiment to see if it can fill back in.

It will not fill back in. See above. There will be no new growth from the brown sections, and any new growth from the sections that are still green is unlikely to cover such a large bare area.

==>>> just wondering where you are.. that wild dingos might be an issue ... lol

just keep cutting on them ... and when you go to far ... and you end up not happy with them ..... give them a proper basal cut at ground level.. and be done with them ...

juniper do not have dormant buds ... [the reason they usually dont sprout from bare wood] ... so if you cut them flush to the ground.. you basically dont even need a stump killer ...

the real question.. to me.. is what are they hiding .... if its a sight block.. you might want to plant a new sight block ... so when you get tired of these ... you will have the new sight block well established ... i have a almost the same thing.. and 15 feet on the other side of it.. is a neighbors house ... i was told mine were:

I really like the aesthetic prunings of liono9, and they can only get better with time! Similarly, it is IMHO not too late for pete to limb up and make the brown appear as if deliberately pruned that way. Of course, OP can try it too!

btw .. i see you had 3 forums.. conifers.. shrubs.. and bonsai ...

this is more along the lines of topiary ... rather than bonsai ... but i have no clue.. if there is a topiary forum ... lol ..

Ive pruned this back hard (not this much though) in years past and it always comes back. Its already got a bunch of new growth in the interior and I only cut it about a month ago.. My gut feeling says in 3 years it will be good as new. Like I said, this is an experiment.

2 1/2 years ago we had a few very cold nights (less than -20) without snow cover. Foliage of several of my junipers were brown. One 25 ft tall J. chinensis 'Blue Point' looked terrible. I cut it down, and found their roots very hard to cut. In case you want to dig out the root ball make sure you have the tools for cutting hard roots, like a gas chain saw.

Juniperus confertifolia appears to bud from old wood. I was surprised to see this, which is why I am noting it.
