I recently purchased a half dozen hydrangeas from a local garden store and they've started blooming. However they are quite droopy, with the droopiest pictured here. They seem healthy otherwise: plenty of water, the get New Jersey summer sun from sunrise to early afternoon, and were planted with a scoop of organic Holly tone.
My assumption is the blooms are sitting on the ground because they're too heavy for the young stem to support. Is that a likely explanation? If so what's the proper way to prune them?
They are Nikko Blues. Thanks!
