mdvaden,
Thanks for the photos. The tree looks like a large topiary; I imagine that's the idea. What kind of pine is it?
I'm wondering about the apical meristem . . .. Is it long, throughout the "candle," allowing the branch tip to continue to grow? Or is it on the tip of the candle and being removed when the candle is cut? Also, when the candle is cut, does this cause the remaining portion to produce a new whorl? Or is the whorl already in the making, so to speak, and simply invigorated by removal of the dominant tip?

The meristems would be at the end of each candle / shoot. And It seems that cutting it, allows new buds to form, producing a new lower meristem.
Seems a new whorl could be produced, like a cluster of buds at the tip, but often it's just a bud or two.
On that tree, I mainly used shears, some hand cuts, and hand pruned some crud and dead twigs from beneath the clusters so they didn't become too heavy of rats nests.
It even looks better when pruned. The photo is late winter after a weather pounding. Two months later, each "cloud" was more tidy, and a bit more flat-topped.
That one was a shore pine - Pinus contorta. Probably the most common one I see that done to out here.
I think the man paid $9000 for that one back in the late 80s. A transplant from a Beaverton location where a few were developed in a landscape. Personally, I don't like to start this type of pruning, and prune just a few existing ones each year.
The one in the picture, had a dome top when I started, and I could not reach above it - no space for a ladder with the fountain in front, and there is a 14' drop-off behind and to the side. So I dissected the top dome into a few cluster that I could reach through.
Took about 4 hours to do that tree each year.
