Preventing the “Winter Burn”: Why Your Evergreens Look Like They Got a Tan in January
Hello neighbors, Jeremy Klice here.
We need to talk about a confusing phenomenon: your shrubs turn that rusty, crispy brown color in February that suggests they spent too much time on a beach in Florida — but no, they’ve been sitting in a frozen snowbank in Jamestown. This is called Winter Burn, or Winter Desiccation. It’s basically dehydration, and it’s the number one reason your expensive evergreens look like toast by springtime.
The Science: Trying to Drink a Milkshake Through a Frozen Straw
Even in the dead of winter, evergreens are still breathing. On bright, windy days, the sun and wind strip moisture right out of the leaves. The plant tries to pull more water up from its roots, but the ground is frozen solid, so the leaves dry out and die of thirst while surrounded by frozen water.
The Usual Suspects: The “Big Leaf” Club
Broadleaf evergreens like Rhododendrons, Holly, and Boxwoods are the most dramatic about it — their wide leaves lose moisture much faster than skinny-needled pines or spruces. If they’re on the south or west side of your house where the wind hits hard, they’re in the danger zone.
How to Stop the Burn
1. The “Last Call” for Water. Water your shrubs deeply in late fall, right up until the ground freezes. Think of this as filling their internal reservoirs before the long freeze.
2. The Mummy Wrap (Burlap). Wrap sensitive, wind-exposed shrubs in burlap (not too tight) to block drying wind and harsh winter sun.
3. Chapstick for Plants (Anti-Desiccant Spray). A waxy anti-transpirant coating locks moisture into the leaves — apply in late fall and maybe again during a mid-winter thaw.
If your shrubs are already looking crispy, don’t panic and chop them down yet — the damage is often just cosmetic. But to avoid it entirely, get that hose back out before the snow flies. Stay warm. — Jeremy
