I bought this trident last summer. It sort of went into winter weakly. I repotted this spring (maybe shouldn't have but it was pot bound bad). It got its first flush of growth but everything looks fairly weak. Thoughts on how to build strength? Full sun/partial sun?
You can't give a trident maple too much sun in MA.... or pretty much anywhere else on the east coast. Lots of water and ferts, too. What's it planted in, soil wise? Tridents are pretty bomb proof when growing strongly, even up north... as long as you protect them from frosts/freezes once they start growing in the late winter/early spring.
The first inch or so of the branching looks funny to me.
If it's nothing else, it's sign that this thing has been growing weak like that for a while, if you consider those beginning of the branches was one,2,or even 3 "flushes" of growth.
Perhaps it is just weak cuz its weak?
Kinda looks like it grows well in fall though maybe, for them reddish tone parts seem one spurt of growth.
