Here are a few ways to overwinter your plants. Sink the pot in the ground, if it is an all weather non-decorative container, to protect the roots from the cold. Or move them into an unheated garage once the plants are dormant. Set the pot on a board and surround it with “stuff” to provide added insulation.

Do you water hydrangeas in winter?

Should I cut back my potted hydrangeas for winter?

The first step in hydrangea winter care is to cut away the old wood at the base of the plant, and remove any dead or weak branches by cutting them off at their base. Be careful not to cut off healthy wood, as this wood will be where your hydrangea will bloom from next year.

Where do you cut hydrangeas for the winter?

Instead, trim back overgrown branches by up to one-third of their height to maintain the shape of the shrub, and cut any dead, damaged or crossed branches back to the base of the affected branch. You can cut back a badly overgrown 'Annabelle' hydrangea to just above soil level in winter after the shrub goes dormant.

What happens if you don't cut down hydrangeas?
