Must You \’deadhead\’ Hydrangeas To Get Another Set Of Blooms After The First Bloom

Question

I have a hydrangea plant in a large pot. It gets partial sun for most of the morning. It’s had a fabulous bloom so far but now the blooms are fading. Do I need to deadhead it in order to promote a second blossoming or, if that’s the only flowering for the year, should I leave it to die back?!

The short answer in most cases is no. Most cultivars will only bloom once per year, but deadheading them once they have died off is ideal.
