How cold does it have to be for plants to freeze?

The general rule of thumb is that most plants freeze when temperatures remain at 28°F for five hours. Of course, there are exceptions to this rule. Seedlings, with their tender new leaves, often give up the ghost when temperatures dip to 32-33°F. Tropical plants have differing low-temperature thresholds.

What is considered freezing for plants?

Light freeze - 29° to 32° Fahrenheit will kill tender plants. Moderate freeze - 25° to 28° Fahrenheit is widely destructive to most vegetation. Severe or hard freeze - 25° Fahrenheit and colder causes heavy damage to most plants.

How do I protect my plants from freezing?

If you are only expecting a light freeze, you may be able to protect plants in a freeze simply by covering them with a sheet or a blanket. This acts like insulation, keeping warm air from the ground around the plant. The warmth may be enough to keep a plant from freezing during a short cold snap.

Should you water plants before a freeze?

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.

Where should I store my plants in the winter?

Tender perennials can be overwintered in a cool, dark basement or garage where temperatures stay above 40 degrees F. (4 C.) but are not too warm to cause the plant to come out of dormancy.

How do you keep potted plants from freezing outside?

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.

Can I cover plants with garbage bags?

Yes – if you secure the plant properly. Garbage bags work to cover plants and protect from frost, but they must not be allowed to touch the plant's surface. Use stakes and supports to create a tent-like structure over the plant, which will retain warm air. Make sure the trash bag goes all the way to the ground.

Can you cover plants with plastic to protect from frost?

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.

Can plants recover from cold shock?

While the damage to the leaves is permanent, plants are pretty resilient. If the leaves are severely damaged, they will die and fall off. New leaves should take their place. It may take several weeks or months to see full recovery, but given warmth, proper light and water, most plants bounce right back.

Will plants freeze at 37 degrees?
