Your tridents are coming along nicely. Especially with the grove, do you use wire or do you rely entirely on clip-and-grow?
On the grove it's been done almost entirely using the clip and grow method. I have wired some branches loosely just to get them going in the right direction but have never done a traditional wiring job on it. On that particular tree I tend to use the "arborist" approach to pruning just to remove long growth and branches that cross and look unsightly. Here is a picture of the grove from a few days ago after I did it's fall pruning and selected a container for it to go into next spring.
