I started a couple of very long term maple projects in spring 2012 and these pics show the progress made to date.
The first is a trident maple and you can see the very humble beginnings by clicking the link.
The next is an Acer Palmatum which has really pushed out a lot of new growth this year. Many of the shoots will be removed completely next spring.
Finally is this humble shohin Acer that has also put on a lot of growth this season and has just been roughly trimmed. Once again a I will remove a number of branches completely before next growing season.
