Help with my 2 blue hydrangeas

Nikki
by Nikki
I recently received 2 hydrangea plants bought from a nursery. They have big blooms on them and are beautiful. I have other hydrangeas of different kinds in my yard but these are different. They don't seem to have hard wood stems and the blooms are so big they are falling over leaving the top of the plant flat. I have them planted in large containers on my deck to keep them from getting too much sun, could them being in containers be the problem? And every branch has a bloom I'd say 10 on each plant if I cut them off will they bloom more? There are no branches with just leaves only on them to make them like shrubs like my other ones. I'm concerned if I cut off the blooms to bring them inside to enjoy, and to also take some weight off the branches there will be nothing left =)
