September in Grand Traverse, Leelanau and Benzie Counties brings crisp morning air, falling leaves, and that familiar itch to wrap up outdoor chores.
Fall is easily one of the best times of the year up north. But it also hands us a tight, unforgiving window to get our properties ready for winter. Taking a few strategic steps right now keeps freezing temps from cracking expensive pipes, stops persistent weeds before they sleep, and sets your turf up to bounce back fast when spring finally arrives.
Tame Water Runtimes
When night temperatures drop into the 40s across Northern Michigan, your grass stops drinking heavily. Morning dew hangs around until noon, meaning mid-summer watering schedules end up wasting water and drowning your soil.
Here’s how to adjust your irrigation system for autumn:
- Cut back watering frequency: Drop runtimes to just one or two mornings per week.
- Flag your sprinkler heads: Stick bright flags on heads near driveway edges and garden borders before aeration crews or heavy mowers roll through.
- Book your blowout early: Schedule your system blowout now! According to the 2026 Farmer’s Almanac, we’ll be seeing our first frost mid-September (so, right now!) through early October.

Knock Out Spring Weeds Before Winter
Most people wait until May to fight weeds, but late September is actually the single best time to knock out broadleaf invaders.
As autumn approaches, perennial weeds know winter is coming. They naturally shift gears, pulling sugars, energy, and nutrients down from their leaves and storing them deep in their root systems to survive the cold.
- Target the taproot: Apply a selective broadleaf treatment in early autumn so the weed carries the solution straight down to the root.
- Stop spring emergence: Destroying the root structure now keeps dandelions and clover from popping back up when the snow melts.

Aerate, Drop Mower Deck & Feed Roots
Fall is the ultimate recovery season for cool-season grass. Summer heat and heavy foot traffic compact our soils tight, suffocating root systems.
Get your lawn ready for snowpack with these steps:
- Core aeration and overseeding: Pull small plugs of dirt out of the ground to loosen packed earth, giving roots room to breathe autumn rain. Pairing aeration with fresh seed fills in thin patches.
- The lower final cut: Drop your mower deck down half an inch for your final mow of the year once top growth slows. Shorter grass prevents blades from matting down under heavy snow, which cuts off airflow and invites snow mold.
- Root feeding: Apply a balanced, slow-release fall fertilizer to fuel root expansion underground rather than forcing leaf growth.

Protect Shrubs, Clean Beds & Store Gear
Cold winds, heavy snow, and hungry wildlife can wreck unprotected landscapes once wild food sources dry up.
Run through this quick property sweep before the first freeze:
- Set up wildlife barriers: Install chicken wire, fencing, or burlap wraps around young fruit trees, arborvitae, and ornamental shrubs by late September to stop deer browsing and antler rubbing.
- Screen against salt and wind: Place burlap screens around shrubs near busy roads or open shorelines to block salt spray and harsh winter windburn.
- Manage fallen leaves: Mulch light leaf cover directly into the turf with your mower to recycle organic matter. Clear thick, heavy piles of wet leaves off the grass and out of garden beds to they don’t smother the soil.
- Leave winter interest: Trim back spent perennials, but leave standing ornamental grasses and seed heads like coneflowers to give overwintering birds food and shelter.
- Pack up equipment and hardscapes: Drain fuel out of lawn equipment, pull fragile ceramic pots indoors, set driveway snow stakes before the ground freezes, and coil hoses inside.
