If a plant is positioned near a window, protect it from heat and intense sunlight during the day and from cold, drafty conditions at night. On a cold winter night, a plant near the window could freeze. Some protection can be gained by placing a sheet of cardboard between the plant and the window. Use shades and curtains or move the plant far enough away from the window to avoid temperature and light extremes. In the summer, avoid placing plants in a car for an extended period of time.
Heat can buildup quickly in a closed car.
Shade the plant from direct sun. The plant can be burned even though the inside temperature is comfortable to you. On cold winter days, wrap plants thoroughly before leaving the store. Use newspaper, paper bags, or plastic sleeves. Place your new plant in the front of the car, and turn on the heater.
