Trees need to grooow to stay healthy. Larches that are constantly pinched, get short stubby branches. Larches that are allowed to grow a bit, get strong and generate lots of branches that one can use to develop the tree.
I have seen and heard arguments for both sides of the pruninggate. I am this year allowing all buds that want to grow, grow. Pruning back once the branches reach 4-6 inches after carefully looking at a bunch of larches I really like. There they have been allowing the tree to grow at least one flush each year. I prefer to have lots of active buds to which I can cut back and get more movement and taper. A branch that does not grow, does not develop ?
