Arizona may be known for its sunshine, but winter can still bring freezing nights, frost damage, and stress to your trees. Whether you live in Phoenix, Chandler, Gilbert, or anywhere in the Valley, protecting your landscape during the colder months is essential.
At PROS Tree & Landscape, we help Arizona homeowners maintain healthy, strong trees year-round. Here’s your complete guide to preparing your trees for winter — the right way.
Arizona’s winters are unique. While daytime temps stay comfortable, overnight lows can dip below freezing.
Common winter risks for Arizona trees include:
Frost damage
Leaf burn
Root shock
Cracked bark
Reduced nutrient uptake
Even desert-adapted trees can struggle if not protected.

Frost is one of the biggest winter threats in Arizona — especially for younger or tropical trees. Even a few degrees below freezing can harm young trees or tropical varieties. Use breathable frost cloths, burlap wraps, or old bedsheets to cover trees overnight. Uncover them during the day to let sunlight and air circulate.
Cover trees with frost cloth or breathable fabric overnight
Remove covers during the day to let the tree warm
Wrap trunks of citrus trees for added protection
Avoid plastic coverings (they trap moisture and damage bark)

Overwatering is a common mistake when temperatures drop.
Water deeply but less often
Allow soil to dry between waterings
Focus on watering the root zone, not the trunk
Water early in the day to prevent freezing at the base
Healthy winter watering helps your trees stay strong through spring growth.
Winter is one of the best seasons to prune many Arizona trees — but timing matters.
Removes dead or weak branches
Reduces storm breakage
Shapes growth before spring
Improves overall tree health
⚠️Avoid pruning during an active freeze, as fresh cuts are more vulnerable.

Mulching is essential in Arizona winters.
Insulates roots from cold
Helps retain moisture
Reduces soil temperature swings
Use 2–4 inches of wood chips or shredded bark, and keep mulch a few inches away from the trunk.
Young trees are the most vulnerable in winter.
Stake only if necessary to prevent wind stress
Add extra mulch around the base
Cover during freezing nights
Ensure proper watering without soaking the soil
If you planted a tree within the last 12 months, winter protection is crucial.
Many winter problems start small and go unnoticed until spring. A professional tree inspection can identify:
Rot
Cracks
Weak branches
Root issues
Pest activity
