Hydrangea help? [View all]

My Big Daddy hydrangea is sort of spreading and I want it to be more bushy and robust.

When can I trim it? What's the "old wood, new wood" thing?

Will rusty nails really make it turn blue? (because it's a Big Momma Hydrangea now)

Looking at images, I think it's the "Annabelle" cultivar of wild hydrangea. NutmegYankee Jun 2016 #7

All white hydrangeas will always stay white, regardless. nt LaydeeBug Mar 2017 #9
