When is the best time to trim or remove a tree in Michigan?
Some tree work is seasonal, some isn’t, and one Michigan rule surprises almost everyone — there’s a stretch of the year you should not prune oaks at all.
The short answer
For pruning, late winter into early spring — while the tree is dormant — is the best window for most species. For removal, any season works; winter is often better than people think. And a dead, cracked or leaning tree shouldn’t wait for a season at all — that’s a call-today situation.
Never prune oaks from mid-April through mid-July
Michigan has oak wilt — a fatal fungal disease spread by beetles that are drawn to fresh pruning cuts. State forestry guidance is clear: avoid pruning or wounding oaks from roughly April 15 to July 15. A cut in that window can cost you the whole tree, and oak wilt spreads through root systems to neighboring oaks. If an oak must be cut in that window (storm damage), the wound should be sealed immediately — one of the few times tree paint is actually recommended.
Why winter removals are underrated
Frozen ground means heavy equipment leaves little to no mark on your lawn. Bare branches make rigging easier and faster. And schedules are lighter, so you often get on the calendar quicker. If you’re planning to take a tree out anyway, winter is one of the best-kept secrets in tree work.
Dead ash trees can’t wait
The emerald ash borer killed most of Michigan’s ash trees, and dead ash gets dangerously brittle fast — limbs shed without warning and the wood becomes unsafe even to climb, which makes removal harder (and pricier) the longer it stands. If you have a dead ash near your house, driveway or play area, have it looked at now, whatever the season.
Signs a tree shouldn’t wait for the “right” season
Large dead limbs over anything you care about. A new lean, or soil lifting on one side of the trunk. Mushrooms or soft wood at the base. Cracks where big limbs meet the trunk. A hollow you can see into. Any of these means get an assessment now — estimates are free, and looking costs nothing.
