Thinking out loud. If you want to keep the tree small and more bush like, then I would go ahead and cut it down to the point you want new growth to come from next season. You might have enough season left to start some new growth even this season. No point in overwintereing wood you are going to cut off in the Spring.

Pitangadieco, thanks for your comments. I was thinking about trying to root the top. Would it be better to wait until it goes dormant. Then put the cutting in the refrigerator, or wait until spring to cut it and try to root the cutting then.

In that scenario, I would wait till it is dormant, and then try rooting it in the Spring.

Thanks pitangadiego I appreciate your advice.
