As summer winds down, your lawn and landscape need a little extra care to prepare for winter. Fall is the perfect season for aeration, overseeding, fertilizing, trimming, and cleanup that will set your yard up for success in spring. One of the most common questions we hear is, “When should I aerate my lawn?” Let’s answer that first, then move through the rest of your fall checklist.
1. When to Aerate Lawn
For cool-season grasses, early fall is the best time to aerate. The soil is still warm, the grass is actively growing, and aeration opens pathways for air, water, and nutrients to reach the roots.
If your lawn has heavy clay soil or sees a lot of foot traffic, aeration is especially helpful. Using a core aerator to remove small plugs of soil relieves compaction and creates the ideal environment for stronger, deeper root growth.
2. Overseed for a Thicker Lawn
After aeration, overseeding helps fill in thin spots and improve turf density. Fall’s cooler nights and steady moisture provide the perfect conditions for new grass seed to germinate and establish before winter.
3. Fertilize for Strong Roots
Fall fertilizer is less about making your lawn look green now and more about strengthening roots for the cold months ahead. Choose a blend high in potassium and phosphorus to help grass store energy and bounce back strong in spring.
4. Trim and Prune Thoughtfully
Fall isn’t just about the lawn—your plants need attention too.
- Perennials: Cut back dead stems and foliage once they’ve finished blooming.
- Shrubs & hedges: Lightly trim to maintain shape, but save heavy pruning for late winter or early spring.
- Trees: Remove dead or damaged branches now to prevent winter breakage.
Smart trimming keeps plants healthy and prevents disease from spreading during the dormant season.
5. Manage Leaves the Easy Way
Instead of raking and bagging, mulch leaves with your mower. Shredded leaves break down quickly, adding organic matter to your soil and reducing the need for extra fertilizer.
6. Adjust Mowing Practices
Keep mowing until the first frost, maintaining your grass at its recommended height. Don’t cut too short—scalping weakens turf and leaves it vulnerable to winter stress.
7. Keep an Eye on Water and Drainage
Lawns still need water in the fall, especially if you’ve just seeded or fertilized. Aim for about an inch per week until the ground freezes. Also, watch for drainage issues—puddles or soggy spots may indicate compacted soil or grading problems worth fixing before spring.
