Bonsai tree

If you are one of those curmudgeons who complains about the overly sculpted look of some Japanese bonsai, you have got to admit that this powerhouse Shimpaku approaches perfection. That trunk draws your eye like few trunks anywhere, with its single living vein, mysterious holow at its base and the spidry fingers and hole at the top. But it’s the tight lush foliage that I want to point out here; the result of some serious trimming and pinching.
Although it is so difficult to advise without seeing an image, in generally saiyng, I pinch far too much on junipers. I recommend cutting the longer shoots that push out of a foliage pad with a scissors, a couple of times a year, rather than trying to create density with pinching. That tends to greatly weaken junipers. Repoyting can rejuvenate a tree that is metabolicaly slowing down because the pot is full of roots.

You can pinch with your fingers.

You can also use the tips of your shears for fine trimming.
