It’s important to protect electrical connections from the elements. Plants can be covered with sheets, towels, blankets, cardboard or a tarp when the temperature is 28f for five hours. Baskets, coolers, and any container with a solid bottom can be put into the freezer. – Protect flowers, fruits and vegetables from frost damage by placing them in a plastic bag and placing it in the refrigerator for a few hours.
If you have a freezer, place the bag in it and cover it with plastic wrap to keep it from getting too cold. Do not place in direct sunlight, as this can damage the plastic. Place in an air-tight container, such as a Tupperware container or an ice cube tray, and place it on the bottom shelf of your refrigerator.
This will keep the temperature of the container from fluctuating too much from day to day, which can lead to mold and mildew growth. Keep in mind that you will need to refrigerate the containers for at least a week before using them again, so be sure to check the expiration date on your containers regularly to make sure they are still good to use.

Are plants OK outside at 40 degrees?
Plants start to freeze when the temperature stays at 28 degrees for more than five hours. Tropical plants can tolerate temperatures as high as 40 degrees. Cold-tolerant plants are those that are able to survive the coldest temperatures. Cold-hardy plants, on the other hand, are plants that can survive temperatures below freezing for long periods of time.
These plants have a hard outer layer of tissue that protects them from the freezing temperatures of the outside world. They also have an inner layer that is warm to the touch. The outermost layer is called the rhizome, and it is made up of cells called mycelium, which is a type of fungus that grows inside the plant.
When the temperature drops below about -20 degrees, the cells in this layer die off, leaving behind a skeleton of dead cells. This skeleton is known as the mycorrhizal network, or M.N., and is responsible for the plants’ ability to grow in cold climates.
