I got that Sergio. I understand you are growing it for few weeks and than cut back. Sure good to prevent another scars and unwanted thickening on parts where you don't want that. I would try to grow one long shoot per branch for whole season, like long as long as it can grow in a season. But that's just me. You are maple expert so you know which methods works for you. Colors are just spectacular. Enjoy autumn colors mate.Thanks Maros. Don't let some of these photos fool you. I do indeed let the tree grow in between stages. Take a look at this one in late June before it was cut back. I usually get a couple of flushes per growing season with the exception of this year in which the tree did not elongate as much as I had expected when it was cut back.
