You will need to bring the pot inside for the winter because the pot will freeze solid and you will lose not only the plant, but maybe the container.
You can deadhead the hydrangea, but don't prune it unless there are dead branches. These hydrangeas flower on both "new" wood and "old" wood, so it you prune you will have less blooms next year.
You can keep the plant in either the basement or garage. Water the container and mulch it to hold the moisture. Check on it occasionally to make sure it doesn't dry out over the winter and water if needed.Â In the spring set it outside when there is no danger of frost (about the middle of May) in a sheltered area and water and fertilize. When it starts to leaf you can move it to its place for the summer.
