Most of the emergency tree calls we take between October and April trace back to something that was visible — and fixable — the previous fall. Prairie winters punish weak trees: early wet snowfalls load branches that still have leaves, extreme cold cracks trunks, and winter winds find every poorly attached limb. Here's the prep that actually prevents damage, in the order we'd do it on our own properties.
1. Deal with known weak points before the snow
Walk your yard and look for the failure points winter will find: dead limbs, cracked or hanging branches, long horizontal limbs over the driveway, and tight V-shaped double trunks. These are precisely what heavy wet snow breaks first — the classic prairie disaster is a September or October dump on trees still in full leaf, when every branch carries double weight.
Removing deadwood and reducing weight on suspect limbs in fall is cheap. The same limb through your windshield in November is not. If a tree has a history of dropping branches every winter, that's the tree to have assessed now.
2. Water deeply before freeze-up — especially evergreens
This is the most skipped item on the list. Trees, particularly spruce and cedar, go into winter far stronger when the root zone is moist at freeze-up. Evergreens keep losing water through their needles all winter (chinook winds are brutal for this), and dry roots in frozen ground can't replace it — that's how you get the rust-brown 'winter burn' on cedars and spruce every spring.
In a dry fall, give trees a long, slow soak every couple of weeks until the ground freezes, focusing on the dripline rather than the trunk. Newly planted trees (first three years) need this most of all.
3. Protect young trunks from sunscald and rodents
- Wrap young, thin-barked trees (maple, apple, mountain ash) with light-coloured tree wrap for the winter — bright sun on frozen bark causes southwest-side sunscald cracks
- Put rodent guards around fruit trees and young ornamentals; mice and rabbits girdling bark under the snowline kill more young trees here than cold does
- Mulch a wide ring 3–4 inches deep over the root zone (keeping it off the trunk itself) to buffer soil temperature swings
- Skip fall fertilizing with high nitrogen — you don't want a flush of tender growth heading into freeze-up
4. During the winter: what to do (and not do) about snow load
When heavy wet snow bends branches, brush it off gently with upward strokes of a broom while it's still fresh and soft. Don't shake the branches — frozen wood is brittle, and shaking snaps limbs that would have survived. Ice is different: never try to break ice off a tree. Let it melt; the branch damage from chipping at ice almost always exceeds what the ice itself would do.
If a limb does fail onto a structure, or a tree starts leaning with cracked soil at its base mid-winter, treat it as urgent — partially failed trees rarely wait for spring. That's a call-us-now situation, any hour: 780-861-2801.
5. Book winter work — it's the smart season for it
Counterintuitively, winter is one of the best times for major tree work on the prairies. Dormant trees handle pruning well, the elm pruning ban is lifted, frozen ground protects lawns from equipment, and crews have more schedule flexibility than in the summer rush. If you've been putting off a big removal or a full-yard prune, a calm winter week beats a July waiting list — and it means your trees head into next storm season already sorted.
