   Winter Care for your Potted Hostas! A frequent question we get is, will hostas survive over the winter in pots, or, how can I winterize my potted hostas?   Although hostas are very forgiving plants, hostas in pots do need some care  over the winter.  Hostas need a six-week period of temperatures below 40 degrees for their winter sleep. But since during this time the potted hostas can be exposed to several freezes and thaws, they need extra care to prevent damage to their roots.

Winter Care for Hosta Plants Hostas are hardy in cold winters. In fact, hostas only need four to six weeks of temperatures below 40 degrees for the hostas to go dormant and get their winter sleep. There is no winter growth during this time like there is with some other perennials.
