Understanding Winter Burn and Its Causes

In Canada’s harsh winters, evergreen trees and shrubs face a big challenge called “winter burn.” This happens when they lose moisture too fast, causing color changes, drying, and sometimes losing branches or leaves³.

What is Winter Burn?

Winter burn, or “winter injury,” is common in areas with cold temperatures, dry winds, and lots of sunlight in winter³. These conditions make the plant’s leaves or needles lose moisture, turning them reddish-brown or tan.

Primary Factors Contributing to Winter Burn

Several factors cause winter burn, including sunny days, warm dry winds, and quick temperature changes³. These stressors can make it hard for plants to keep their moisture, leading to winter burn symptoms.

Importance of Recognizing Symptoms

It’s key to spot winter burn early for treatment and prevention³. Signs might not show until spring, when new growth reveals the damage. Look for needles turning light tan or reddish-brown, discoloration at tips, and branch death in bad cases.

Knowing the causes and signs of winter burn helps us protect our trees and³ keep them healthy for years to come. Check out more winter landscaping tips to help.

Best Practices for Preventing Winter Burn

As Edmonton’s cold winters come, keeping our evergreen trees and shrubs healthy is key. By following a few important steps, we can stop winter burn and help our plants survive the cold⁴.
