Prepare your Minnesota trees for winter with this fall checklist — pruning, branch removal, trunk wrapping, deep watering, EAB checks, and scheduling winter tree work.

Minnesota winters are no joke. Heavy snow, ice storms, and months of frozen ground put enormous stress on your trees. The good news? A little preparation in fall can make a big difference in how well your trees survive — and how they look come spring. Here's what every Minnesota homeowner should do before the first hard freeze.
Fall is one of the best times to prune most tree species in Minnesota. Once trees begin entering dormancy and leaves start to drop, it's easier to see the branch structure and identify problems.
Schedule fall tree trimming before the ground freezes and access to your property becomes more difficult.
This is arguably the single most important fall tree task. A dead or weakened branch that seems harmless in October can become a serious hazard when it's carrying 30 pounds of wet snow in December.
Think of this as your tree's annual physical. Before everything goes dormant, take a close look at:
If anything concerns you, a tree health and risk assessment can give you peace of mind before winter.
Young trees with thin bark — especially maples, lindens, honey locusts, and fruit trees — are vulnerable to sunscald during Minnesota winters. This happens when warm winter sun heats the bark on the south or southwest side, and then temperatures plummet overnight, causing the bark to crack.
Trees continue to lose moisture through their bark and any remaining foliage during winter, even when the ground is frozen. Going into winter well-hydrated makes a huge difference.
Those beautiful fall leaves can harbor fungal spores that overwinter on the ground and reinfect your trees in spring. This is especially true for:
Rake and remove (or mulch-mow) fallen leaves, particularly from trees that showed disease symptoms during the growing season. It won't eliminate disease entirely, but it significantly reduces spore load for next year.
If you have ash trees on your property, fall is a critical time to inspect for signs of emerald ash borer (EAB):
EAB has been confirmed throughout Minnesota and is lethal to untreated ash trees. If you haven't started a treatment program, fall is a good time to plan for spring treatment. Learn about our emerald ash borer treatment options.
Many homeowners don't realize that winter is actually an excellent time for certain tree services:
Scheduling winter work in the fall often means better availability and potentially better pricing.
Don't wait until the first snowfall to think about your trees. A little fall preparation goes a long way toward preventing costly storm damage cleanup and keeping your trees healthy for years to come.
