You can overwinter them by moving the pots into a cold frame or unheated garage for the winter after the first hard frost. Since all perennials require a period of dormancy or a cold treatment to bloom, don't overwinter them in a greenhouse or other warm place where they will not go dormant.

How do I protect my container plants in the winter?
To protect planted terra-cotta and glazed containers left outdoors, wrap the sides of the pots with layers of bubble wrap or burlap covered with plastic wrap to prevent them from absorbing additional moisture once the plants go dormant and their water requirements are minimal.
Can perennials survive in planters?
If the container is large and able to withstand the elements, and if the plant is at least one zone hardier than your area (i.e., if you live in Zone 5, herbaceous perennials in containers need to be hardy to Zone 4 or lower), the likelihood of successfully overwintering the plant in its pot outdoors is high.

How do you keep perennials alive in the winter?
Store Your Perennials Indoors
An unheated garage, shed, or basement with a temperature range between 30 and 40 degrees can provide a perfect environment for overwintering perennials. Dormant plants should be brought inside and watered periodically whenever the temperature is above 40 degrees.
Can you use garbage bags to cover plants?
Never use plastic of any kind, including black plastic garbage bags, to cover plants, as plastic conducts cold to the leaves and will increase the likelihood of damage to the plant. Old sheets, blankets, drop cloths and special frost protection blankets (called Reemay cloth or floating row covers) work best.
How do you protect outdoor potted plants from freezing?
Wrap pots in burlap, bubble wrap, old blankets or geotextile blankets. It isn't necessary to wrap the entire plant because it's the roots that need shielding. These protective coverings will help to trap heat and keep it at the root zone.

What do you do with perennials at the end of the season?
Perennials To Cut Back In The Fall
If perennials (like Bee Balm or Phlox) were diseased this past season, cut the foliage all the way down to the ground and don't compost it. Throw it away or dispose of it in an area far enough away from the garden that other plants won't be subject to the disease.
How do you store lavender for the winter?
Whenever the soil gets dry over winter and isn't frozen, add a little water to the lavender pot -- just enough to dampen it. A third option is taking the lavender inside and keeping it alive next to a sunny window as you would a houseplant. Again, don't overwater.
Can I cover my plants with cardboard boxes?
Cardboard boxes (or even newspaper) can be placed over perennials and shrubs as a nighttime cover. Recycle sheets, blankets, and drapes by using them as plant covers. Cover of any type should shield plants without actually touching them.
What is the best thing to cover plants with?
Bed sheets, drop cloths, blankets and plastic sheets make suitable covers for vulnerable plants. Use stakes to keep material, especially plastic, from touching foliage. Remove the coverings when temperatures rise the next day. For a short cold period, low plantings can be covered with mulch, such as straw or leaf mold.
Will a covered porch protect plants from frost?
A covered porch usually provides protection from light frost, but the garage or sun room is better for freezing temperatures. A couple days in darkness won't hurt the plant. Or move them out during the day and back in at night, if cold temperatures persist.
Will one night of frost kill my plants?
A light frost may cause minimal damage while a severe frost may kill plants. Young, vulnerable plants are much more susceptible to a light freeze, which occurs when temperatures are 29 to 32 degrees Fahrenheit, while mature plants may only suffer from short-term effects.
Will Christmas lights keep plants from freezing?
You'd never dream that Christmas lights would give off enough heat to keep your plants from freezing, but they will. You can string them up and down your plants. This option works great for trees as well. Not only will you look festive on cold nights, but you'll also awake to plants that have been kept warm all night.
What to cover plants with to keep them from freezing?
