Pinching back young canes
I brought this up a few years ago, but thought I'd raise it again, since it's never discussed in rose books. You can often induce branching by pinching back.
Sometimes basals or major laterals are too strong. They outgrow the rest of the plant and terminate in an awkward cluster, then you cut them back and waste a lot of growth. But if you remove the growth tip early, the shoot should stop and produce laterals relatively close to the ground, resulting in more bloom and a denser plant.
More and lower branching can be desirable with leggy narrow hybrid teams, with climbers that need their legs clothed, with shrubs that make 8' basals, etc.
It doesn't always work, in that you may get only one lateral, thus no benefit, and bloom is delayed a week or two. That is more likely to happen with weaker shoots, or it might be a variable between varieties as well. (I should have kept notes over the years, but I haven't.)
Pinching is is best done when the shoot is 12" long or less, and be alert, because basals can grow 2" a day. Be sure to get the solid growth tip and not just leaves. The latent buds in leaf axils near the growth tip will respond quickly, often in just a week. Clipping the shoot further down can work, but the response may be slower.
So eight days ago I pinched a fat basal on 'Tess of the d'Urbervilles.' Today it already has three branches coming. I pinched it at 12" but the upper stem telescoped out another foot before slowing down. So, ideally, I should have stopped it sooner or clipped a few inches down to get the branching closer to the ground. Still, it's a good result.
