Great Falls Wind Events Are Why Tree Trimming Can't Wait Until Spring

Great Falls sits in one of Montana's most consistent wind corridors, where gusts regularly exceed 50 mph and rapidly shift direction. Dense, unpruned canopies act like sails under those conditions — the drag on a single overloaded branch can split a union that looked solid for decades. When that branch is positioned over a roofline or near a power drop, the cost of inaction becomes immediate and expensive.

AJ's Tree Service approaches trimming by evaluating each tree's weight distribution before making any cuts, identifying co-dominant stems and included bark — the structural flaws most likely to fail under lateral load. Removing those specific branches reduces wind resistance without stripping the canopy unnecessarily. After a proper trim, the tree's silhouette is visibly lighter at the outer edges, and branches no longer rub against each other during gusts, which stops the bark wounds that invite fungal entry.

Where a cut is made determines whether a tree heals cleanly or develops a cavity. Cuts flush against the trunk remove the branch collar — the raised tissue ring that produces callus — and leave a wound that stays open for years. Cuts made too far out leave stubs that die back, creating dead wood that insects colonize within a single season. Proper pruning preserves the branch collar, and within two to three growing seasons the wound rolls closed with new bark, leaving no entry point for decay.

Timing in Great Falls follows the tree's biology, not the calendar. Most deciduous species benefit from late-winter trimming when they're dormant and pathogens are less active, while certain fruit and ornamental trees require post-bloom cuts to avoid removing the next year's flower buds. Evergreens along Central Avenue corridors and residential streets near the Missouri River benefit from thinning cuts that improve airflow and reduce snow-load accumulation on lateral branches.

Scheduling tree trimming in Great Falls before the next wind season means branches are evaluated and removed on your timeline — not during an emergency. Reach out to get a trimming plan in place for your property.

Most trimming-related failures aren't caused by storms alone — they're caused by structural problems that existed before the storm arrived. Understanding what goes wrong helps you recognize when your trees need attention before damage occurs.

• Co-dominant stems with included bark split at the union under wind load, often taking sections of the trunk with them
• Dead interior branches fall without warning because they lose bark attachment gradually and silently
• Flush cuts made against the trunk prevent callus formation, leaving cavities that fill with water and accelerate decay
• Unpruned canopies over driveways and utility lines in Great Falls create recurring storm-damage claims
• Topped trees — cut straight across rather than selectively pruned — produce fast-growing, weakly attached sprouts that fail within years
