need help pruning/shaping tree after grafting

[boxturtle]

Hi All,

So my sir prize graft took it's been about 2weeks since  it flushed from bottom right node of the scion.  My question is should I prune the top part of the scion where i marked it? the growth came out pretty nice and straight so thinking about keeping that as the tree. I was concern that there is alot of energy stored at the tip of the scion and if I cut it.  it might kill the graft?  I'm i just over thinking this? not just this but for other grafts as well do you prune part of scion to shape your trees.....or should I  wait awhile before doing that?

I've only done a small amount of grafting, but I've had good success with waiting for three or four growth flushes before I prune like you suggest if it makes sense for how I want to shape the tree. I've also just left them, and if the tree decides that part is no longer useful, it will die back on its own. Any part that turns brown can be trimmed off.
