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.
Plants aren't fussy about what type of covering you use (with one exception); old sheets and towels are usually on hand and are easy to use. Burlap and newspaper are also useful as coverings. Cover your frost-tender plants in the evening, making sure that there aren't any gaps where the heat can escape.
So with plants that are close to the ground you can protect them from a frost, or even a freeze if you cover them up. You can use plastic, newspaper, bed sheets, plastic tarps, anything you can find.

First, it's good to know which plants are sensitive to temps around 35 or 40 degrees F. These are common tender plants that will need some protection. Hanging baskets: begonias, calibrachoa, gerbera, impatiens, vinca, euphorbia, and scoparia.

Thoroughly Water plants if it won't rain before the freezing temperatures arrive. It may sound illogical. However, the moist ground stays warmer than dry soil. Watering the night before the freeze will insulate the grass and plants' root structure and decrease the potential for cold injury.
Bring Plants Indoors
Bringing plants indoors is the easiest way to protect them from frost or freeze damage. Potted tropical and annual containers can be pulled into a heated room, porch, or into a protected and warm structure, such as a garage, to protect them overnight.
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.
Potassium and magnesium provide optimum frost protection. Freezing temperatures without protective snow or alternating frosts can cause severe damage to agricultural crops. The nutrient potassium has a significant influence on the frost resistance of plants.
If it stays cold for more than one night, can I keep my plants covered, or should I remove the coverings at some point? A. Our recommendation would be to remove the cold protection covering once temperatures are above 32 degrees.
Most houseplants are native to tropical areas and will not tolerate freezing temperatures. Many indoor plants will see damage when temperatures drop to the mid to lower 40s°F and nearly all will die if exposed to below freezing temperatures.

Place cardboard boxes, large trash cans, or plastic tubs over outdoor plants. Be sure to cover the plants all the way to the ground. The warmth from the soil is what keeps the plant warm, since the soil takes longer to freeze.
Each plant has a different threshold when it comes to dealing with the cold. Some plants can survive outside even when temperatures hit freezing. Others need to be brought indoors when temperatures reach the mid-40s.
How to Cover Plants for Frost Protection: What to Use. Your first inclination may be to grab a vinyl tarp or plastic trash bags. This is definitely not the best idea. Plastic or vinyl materials are normally too thin to provide adequate insulation and since they do not breathe, moisture can get trapped inside.
