Will plants be affected in anyway if it is too cold/hot?

When transporting plants, remember the two seasons of the year that can cause damage to the plants, the hot summer and the cold winter months. In the summer, avoid placing plants in a car and leaving the car shut up, because temperature will rise and destroy the plant in a short period of time. If you have to travel for any distance at all, the plant can be burned by the sun shining on it even though the air conditioner is on and the temperature is comfortable in the car. Shade the plant from direct sun while it is in the car.

During winter months, wrap plants thoroughly before leaving the store to carry them to your car. A short run from the store to the car in very low temperatures can kill or severely damage plants. Wrap plants thoroughly with newspaper or paper bags, and place in the front of the car and turn on the heater. The trunk of most cars is too cold to carry plants safely during winter months.

On an extended trip make special arrangements so that plants will not be frozen or damaged by cold weather. Many foliage plants will be damaged considerably if the temperature drops much below 50o F., so maintain as warm a temperature as possible around these plants when transporting them from one location to another.
