Petunias have a base temperature of about 39 degrees F and are considered cold tolerant; however, freezing temperatures can kill petunias because the plants' cells need the sun's energy for photosynthesis.nce petunias have endured frost or freeze injury, there is not much you can do to save the plant. At times, frost-injured plant parts can be cut back, and plants may outgrow the damage. Petunias can survive the light frost of southern climates, as petunias will come back in the spring following a hard freeze.
When temperatures rise to greater than 95Â°F for more than a day or two most warm-weather crops will stop growing and setting fruit. (The same happens to cool-weather crops at about 80Â°F.). If high temperatures persist, it is best to protect vegetables from sun and heat.The best course of action is to keep direct sun off of foliage and to lower the temperature of plants.hading Plants in Hot Weather: â¢ Use shade cloth to protect plants.
