How cold is too cold for plants to be outside?

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.

Can geraniums survive 40 degrees?

Temperature Thresholds

How cold is too cold for pansies?

Pansies have a tolerance to low-temperatures and actually thrive in cool weather (40°-60°F) (Kwon 1992). They are capable of surviving temperatures down to the single digits, but when the air temperature drops below 25°F, pansy foliage will wilt and turn a gray-green color.

Can plants survive a freeze?

Some hardy plants may not be damaged. A "hard frost" or "killing frost" comes when the temperature drops further, below 28 degrees, for a longer time. It will kill the top growth of most perennials and root crops. ... Remember to remove the protection in the morning so the plants can get warmth and light from the sun.

What temperature is too cold for geraniums?

Geranium Temperature Tolerance

While geraniums can withstand cooler temperatures and even light frosts, hard killing freezes -- when temperatures drop below 20 degrees Fahrenheit -- result in freeze damage and possibly death of the geranium. The geranium minimum temperature Celsius is -7 degrees.
