Perennials in containers can be dug into the soil if you don’t have an appropriate indoor area. Perennials should be placed at the same level as the surrounding ground. It will help moderate the soil temperature in the containers, avoiding excessive freezing and thawing of the plants. Perennial plants can also be transplanted from containers to the ground, but be careful not to over-water them, as this can lead to root rot.

How do you keep potted perennials over winter?
The first option is to place the pot in an unheated garage (or other unheated but protected spot). The pot will be protected from freeze/thaw cycles thanks to the protection from the building. Before placing the plant in the garage, wait as long as possible.
If you do not have a garage or other protected area, you will have to wait until the weather warms up and the temperature rises above freezing. If you wait too long, the plants will not be able to take the heat and they will die.
This is why it is a good idea to store the pots in a cool, dry place until you are ready to use them.
Can you leave soil in pots over winter?
You can leave plastic pots filled with soil outside all winter. Winter rains and snow can fill the pot, and freezing temperatures can cause the water to expand. The ice cube effect occurs when the frozen soil expands out the bottom of the container.
If you don’t have a container big enough to hold the soil, or if you want to keep it in the freezer for longer periods of time, use a plastic bag with a hole cut in it. This will allow you to put your soil directly into the bag, rather than having to dig it out with your hands.
How do I protect my container plants in the winter?
Wrap pots in burlap, bubble wrap, old blankets or geotextile blankets. It’s not necessary to wrap the entire plant because it’s the roots that need protection. The protective coverings help to trap heat and keep it at bay.
If you want to keep the plant cooler, you can wrap it in a plastic bag and place it on a window sill or in the back of a closet. If you don’t have a room with air conditioning, it may be best to leave your plant outside and allow it to warm up on its own.
What do you do with perennials in the winter?
Cut back stems, reduce watering and dig up bulbs As summer turns to autumn, and your perennials have finished for the season, stems should be cut back to between 6 and 8 inches from the ground and watering should be drastically reduced. This will help prepare the plant for cooler and drier weather in the future.
Will perennials survive a frost?
Most perennial plants do not suffer frost damage and do not need to be covered. Hearts are sensitive to frost. They should be covered to protect their flowers. Any plants that have been budded up should be covered. These plants are not frost sensitive and can be grown year-round in most climates.
However, they do require a little extra care in the spring and summer to keep them looking their best. The best way to do this is to cover the plants with a layer of mulch. This will help keep the soil moist and prevent the roots from drying out. Mulch can also be added to the bottom of the pot to help prevent root rot.
Can you leave outdoor plants in plastic pots?
Handling costs and accidental plant damage can be increased because of the ability of these pots to break in the soil. More durable containers, usually plastic, keep the plants safe, especially if they get wet. If you’re going to use a potting mix, make sure it’s a good one.
You don’t want to spend a lot of money on a mix that’s not good for your plants. If you can’t find the right mix at your local garden center, look for one that has been tested and approved by the U.S. Department of Agriculture.
