I purchased a nursery Fukuzumi white pine several weeks back to begin training. It was a 3ft tree 1.25" at the base. So far I've slip potted it into a pond basket and this past week I chopped it 1.5" above the second whorl. I've left a stump to die back that I'll reduce this winter or next. Also just decandled it. I have a new leader selected from the main branches at the second whorl. There are two other main branches at that whorl along with many smaller ones about 2+ candle/buds in length. Can I also knock down the other two main branches at the second whorl to direct growth into the new selected leader at this time? I'd leave 3/4" stubs to cut flush later on.
