Tips On Winterizing Trees From The City Of Laramie

By: Chris Luczkow

 Preparing Your Trees for Winter: 

• Trees located in the right-of-way, often indicated as the landscape area between the curb and  sidewalk, are the maintenance responsibility of the abutting property owner. Prune dead, broken, and  weak branches out of your trees. Dead trees and dead branches shall be removed as soon as possible  to prevent injury or damage when they fail. High wind or heavy snowfall events cause weak branches,  dead or alive, to fail. Prune your trees and shrubs to clear the surface of sidewalks by a height of 8 feet  and the surface of the street and alley by a height of 13 feet. Prune to provide traffic visibility at  intersections. Clear street signs: Stop, Yield, School Zone, and Speed Limit signs.  

• Evergreen trees have normal browning of the inner needles, the needles closest to the trunk, this time  of year. 

• If it is a dry winter, water evergreen trees on a warm day at least once a month, if the water will  somewhat soak into the ground. Deciduous trees should have moist soil in the root zone and may need  water occasionally throughout winter. 

• Young evergreen trees and shrubs may survive the winter better with a sprayed on anti-transpirant or  anti-desiccant. Apply the anti-transpirant in November and possibly again in February. Read the label  carefully. Some conifers react differently to the spray. 

• Apply three to four inches of coarse textured mulch around the trunk, but not touching the trunk, in as  wide of an area as possible. The mulch can be wood or bark chips one to three inches in size, shredded  bark, or rock larger than one inch in size. 

• Wrap or shade the trunks of young and thin barked trees after the leaves have fallen off. Use materials  designed for protecting tree trunks. Remove trunk protectors in spring.
