I have a volunteer I found in my yard that I've been growing - I think this is year 4. I've observed that they (spontaneously) bud along new stems. Basically I've just treated them like spruce = cut/pinch back to a bud. IOW, they naturally form a ramified 'frond', but it is very elongated. Cutting back makes the foliage 'bushier'. I've played with pinching the soft tips after new growth has extended a bit, but I haven't done enough to convince myself pro/con about the practice. Likewise, I'm still a bit befuddled about pinching the soft tips of hemlock (tsuga).
The Mirai YouTube teaser seemed to say that pinching the soft tips is effective causing budding. If this is all there is to Ryan's technique, that is pinching is a once a season thing, then there is no need to refrain from it for a season. What would be bad is to pinch and after a few weeks pinch again and after a few weeks .... etc. because this would remove the strong auxin producers for an extended period of time --> suppressed root growth.
