Add mulch. Many tender plants will benefit from mulch over their roots for added protection in winter. Cover them up.
How do you protect outdoor potted 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.
How do you protect outdoor plants from freezing?
Cover Plants – Protect plants from all but the hardest freeze (28°F for five hours) by covering them with sheets, towels, blankets, cardboard or a tarp. You can also invert baskets, coolers or any container with a solid bottom over plants. Cover plants before dark to trap warmer air.
What do you do with potted plants at the end of the season?

Can you use garbage bags to protect plants from frost?
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.
Can you use garbage bags to cover plants?
Plastic – Plastic is definitely not the best winter covering for plants, as plastic, which doesn’t breathe, can trap moisture that can kill the plant in a freeze. You can use plastic in a pinch, however (even a plastic garbage bag), but remove the covering first thing in the morning.
At what temperature should you cover plants?
When the temperature reaches around 28 degrees F for five consecutive hours, protect your plants by covering them with sheets, blankets, towels, cardboard, or a tarp. Cover the plants before dark to trap them in warm air and don’t allow the coverings to touch the foliage.
How do I save my potted plants for next year?
The first option is to place the pot in an unheated garage (or other unheated but protected spot). The protection from the building will be enough to keep the pot from freezing too hard and to protect it from freeze/thaw cycles. Wait as long as you can without risking the plant before placing it inside.
Can you keep perennials in pots over winter?
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.
What is the best material to cover plants from frost?
Bed sheets or comforters work best for covering large plants and shrubs. Newspaper can be used on low-growing foliage, but it can often be difficult to get it to stay in place. I have used old pillow cases, sheets, towels and even cardboard boxes.
Can you use cardboard boxes to protect plants from frost?
From that experience, I’ve found the best frost protection for your outdoor plants is either free or cheap. Cardboard boxes and brown grocery sacks make perfect frost cover and at the end of the season can be recycled. I keep various boxes on the patio and when frost is forecast simply put one over the plant.
Should plants be covered for winter?
Add a Layer of Mulch It’s like a blanket that covers your plants. A common winter problem is heaving or uplift of soils caused by freeze-thaw cycles. When soil is wet, it’s much harder to freeze solid. Give your plants a quick watering and apply a thick 3- to 5-inch layer of mulch after the first frost.
Will watering help prevent frost?
If it is not going to rain before the freezing temperatures arrive, you should water plants thoroughly. This is because moist ground stays warmer than dry ground. Watering the night before the freeze arrives will insulate the root structure of the grass and plants, decreasing the potential for cold injury.
What is a frost cloth for plants?
Frost cloth is a commercially woven fabric that is light enough to allow air flow and light penetration, but thick enough to help retain warmth from the soil and protect the plant from frost. Always use frost cloth designed for covering plants.
Should you water plants before a freeze?
Cold weather prep for plants in winter Drought-stressed plants are more susceptible to cold damage, so watering plants a few days in advance of a cold snap is beneficial. Watering just before the freeze can help too by creating warmth, and the water loses its heat slowly over the hours into the colder temperatures.
Will a tarp protect plants from frost?
Do not use plastic, such as tarps or plastic sheeting to cover plants. Plastic will transmit cold air to the plants, causing more harm than good. We recommend using cotton fabric or frost cloth to protect plants from frost. Additionally, the cloths can be reused year after year to protect your plants.
What is a frost blanket for plants?
Frost blankets are garden covers made of lightweight, 100% polypropylene fabric. Frost blankets are ultra-lightweight, keeping your plants safe from damage. Unlike commonly used alternatives like bed sheets, burlap, or painter’s tarps, the fabric allows plants proper airflow.
