Fall Tree, Lawn, and Pest Checklist

Fall Tree, Lawn, and Pest Checklist for Minnesota Homeowners

September 17, 2026

As summer says its long, warm goodbye and those first golden leaves start to tumble down, it’s a great time to give your home and yard a little extra TLC. Think of fall prep as your chance to set up a smooth, stress-free winter and a lush, healthy spring. Whether you’re a seasoned Minnesota homeowner or just settling in, let’s walk through some simple, practical ways to care for your landscape, lawn, and home as the seasons shift.

Fall Tree & Shrub Care

Keep Them Hydrated:

During dry spells, including drought conditions like we’re experiencing now, water all your trees, bushes, and evergreens deeply once a week until the ground freezes. Consistent watering helps them head into winter healthy and ready to thrive come spring!

Protect Their Roots and Bark:

Blanket your trees and shrubs with a layer of mulch to keep their roots cozy and moist through the chilly months. The rule of thumb is 2” deep, keeping the mulch away from the base of the tree. Got young or thin-barked trees? Wrap them with plastic tubes or chicken wire to keep curious critters at bay. In areas with high deer pressure, consider installing a larger temporary fence around new trees to prevent deer browsing and rubbing over the winter.

Feed for the Future:

Early fall is a perfect time to give your trees, especially evergreens, a little boost with fertilizer. It helps them stay healthy and bounce back from winter stress.

Quick Check and Prune:

Once leaves have dropped, take a stroll around your yard and look for any branches that might need a trim. Fall is a great time to begin dormant pruning, giving you a clear view to spot any trouble before winter storms roll in.

Fall Lawncare

Keep Up with Leaves:

Recent research shows that leaving leaves on your lawn won’t smother the grass. In fact, mulching leaves by mowing them into small pieces and leaving them in place adds nutrients and organic matter to your soil. This simple step supports a healthier lawn and reduces yard waste; just make sure thick layers are broken up so sunlight can reach the grass below.

Give Your Lawn Some Air:

Aerating your lawn (even just once in the fall) helps roots grow deep and strong, and it’s a great excuse to get outside one more time before the cold.

Fill in Bare Spots:

After aerating, toss down some grass seed to help fill in any patchy spots and set yourself up for a lush, green lawn next spring.

Don’t Retire the Mower Yet:

Keep mowing until your grass stops growing (yes, even into October some years!). Just raise the mower blade a notch to keep the roots protected through the cold.

Feed Your Lawn:

A fall application of fertilizer gives your grass the nutrients it needs for strong roots and a quick comeback in spring.

Care for Your Tools:

Give your lawn tools a little love before you stow them away. Clean and service them now, and you’ll hit the ground running when spring rolls around.

How to Prevent Pests This Fall

Inside the House:

Try to keep things tidy and clutter-free, especially in those easy-to-forget storage spaces. Less clutter means fewer hiding spots for pests.
Snacks and leftovers belong in airtight containers, and a quick sweep for crumbs goes a long way toward keeping critters out.
Notice any leaks or damp corners? Fix them up and consider a dehumidifier to keep moisture-loving pests at bay.

Around the Yard:

Rake up leftover leaves, clear debris, and trim back bushes around your home’s foundation. It helps keep pests from finding cozy spots to sneak in.
If you’ve got firewood, stack it off the ground and at least 20 feet from your house. It’s an easy way to prevent unwanted guests from moving in.
Before you bring in outdoor furniture or fall decorations, give them a quick look for hitchhiking bugs or spiders.

Seal Up the Gaps:

Check screens on windows, doors, attics, and crawl spaces for any tears or gaps, and fix them up before it gets too chilly.
Look for worn weatherstripping and any cracks or holes around the outside of your home, especially near utility lines and your foundation. Mice can squeeze through openings as small as a pencil, so take time to seal up even the tiniest gaps. Sealing those up now saves you headaches (and heating bills) later.
Here’s a fun tip: Swap your outdoor bulbs for yellow or red ones. Bugs aren’t as attracted to those colors, so you’ll see fewer critters buzzing around your door.
