I was running through some archives of images off an old camera and I got these together of this maple I've been growing for the last few years.
2014 - Focus on the side branches has improved the shape and give more fine branches. The inter-node length is also much improving now. My maple ( and general ) pruning and technique is also much improved.
2012 - Ice cream cone shaped. Target height achieved so its time to focus on the side branches now. and develop more fine ramification.
2009 - Trunks held apart with trimmed lengths of chopsticks. I got over enthusiastic and defoliated - would have been better off selectively trimming.
