The cold season is upon us, and it’s important to protect our plants and trees. Our cold and potentially freezing conditions last from December until March typically in the Salt River Valley area. Cold temperatures are defined as 32 degrees or less for more than two hours overnight. Occasionally temperatures fall in this range during the daylight hours also.

If there are going to be cold temperatures overnight, here are some things that can be done to protect trees and plants:

1. Water the area around the tree or plant the evening before the cold temperatures are due to occur. This will seal up the top soil and keep the root system from freezing.
2. Cover the tree or plant with burlap or a bed sheet. This keeps the heat of the plant from escaping too quickly and helps keep the outside cold temperature from doing more harm. Plastic sheets are not recommended as cold air can be trapped under the plastic and the heat from the plant will be more or less ineffective for self-protection.
3. The use of a floodlight centered at the base of the tree or plant can also keep the temperature up to a less harmful level. Make sure the light is placed in a manner and location that will be dry.

Only use these suggestions during the cold periods in question. It might be a bit of a hassle to manage this process during the cold season, but in the long run it can save your valued plant or tree.
