Blushing Bride shaping ?
Last summer while leaving my local Lowe's in the parking lot I noticed a branch of hydrangea in the parking spot next to mine. I picked it up and took it home figuring I had nothing to lose. It rooted quickly and this year rewarded me with several blooms. I believe it is a BB. Right now it is 3 branches and about shin high. My question is will it fill out on it's own or do I need to prune to encourage a less gangly appearance?
