Cutting the blooms off those stems closest to the ground should be enough pruning for those. For the upright ones, cut back to about 24-36". New branches should grow out and up from the upright stems, and new vertical stems should grow from the ones near the ground. Everyone wants a full bodied shrub; as it fills out with more branches, you can prune less and less each year. Once there are enough branches growing upright, you can simply trim the ones that stick up "too far" compared to the rest. So next year you might decide to prune the upright stems to 40", etc. depending on how many have caught up to each other.

Everything you leave on the plant should get thicker with time, making for less flop, which contributes to pruning becoming less important over extended time.

I would just prop up the blooming ones--maybe trim back the tall one a bit.

I personally don't think doing a lot of fussing over a new plant accomplishes much. New plants just need to get older. With time, they will outgrow some of the traits the bug you when they are young.

Thank you both, I really appreciate your advice. The one that bothers me the most is the one in the middle, so I will cut that back and maybe leave the others as they are for now, or maybe once the blooms fall off, I can trim them back just a little so they are not hitting the Rhodie next to them.

I haven't prune mine at all for the past 3 years. It is a very upright grower and has nothing down low. It is so upright I have a little lime and a f&e hydrangea underneath it. I would keep it as is and let it get older. Mine took off fast and are nearly 4-5 feet tall and wide in 4 years
