I have a couple of Japanese Red Pines that I recently obtained. I have not found a lot of information on their training techniques. They both are putting out pretty nice candles, not as vigorous as black pines, but stronger than any of my other pines (lodgepole, mugo, ponderosa). They both are ready for branch ramification/development. I'm thinking they should be treated pretty much like black pine, but I would sure like to hear from anyone with any more definitive information.
