Vanilla Strawberry Hydrangeas Turning - 2019

This is the third season with a set of Vanilla Strawberry Hydrangeas that are planted outside of our front porch facing due East.  Here is the post showing what the plants looked like in 2017 - the first season.  And here's the post showing the pink color emerging in 2018.  This year the plants are (obviously) the largest, most mature that they have been and some of the blooms are quite large.  Not Limelight or Incrediball large, but nice sized and cone-shaped.  

The past few early Springs, I have pruned these bushes and trimmed off some of the old growth to try to shape the plant a bit.  And, now I'm wondering if - for shape purposes - that's not the best move to make?  Reason I say that is that each of these hydrangeas have a TON of blooms down near the ground and like three or four huge, tall shoots each with a flower on top.   But, they almost look like a plant with a fat base and a couple of limbs climbing out of a vase.    

I'm going to plan to NOT prune them this off-season and we'll see what the results are come late Summer.
