Well that is just not true. Healthy ones in the ground here never produce scale foliage. They are anything but stressed. If anything, it's the other way round. Unless you call a juniper that puts on 3 feet of new growth in a season stressed...One more thing... a healthy mature Procumbens can make scale foliage like a shimpaku. If the tree is stressed, it produces the juvenile foliage.
Well... you asked how they do them in Japan, so I told you.
You can't get growth this tight and close using just scissors.
Pinching all the tips can weaken the tree. The growing tips produce auxin. Auxin is the hormone that stimulates root growth. If you remove the auxin, the roots don't grow as vigorously, and the tree could weaken.
Also not entirely accurate Adair. If it was then it would be impossible to cut the head off a cutting and root it without artificial hormones. Something which has been done for centuries. I always remove the soft part of a juniper ctting before striking it. Auxins are produced in the stems and the roots as well as by bacteria in the rhizosphere. They are translocated throughout the plant
Pinching the tree will not weaken it any more than removing the same amount of foliage mass with scissors. You will probably also remove the same amount of auxin cutting with scissors as pinching if you remove the same foliage mass. Unfortunately pinching does lead to blackened tips in conifers. By scissor cutting only you just THINK the tree is healthier because you can't see all those brown tips.
