What you do to your lawn and garden in the fall has an outsized effect on how everything looks come spring. A thorough cleanup now protects your grass from disease, gives perennials and shrubs their best shot at surviving winter, and means a lot less scrambling once warm weather returns. Here are nine steps worth working through before the ground freezes.
Keep up with leaf removal
A thin layer of leaves is fine, but a thick, matted layer blocks light and traps moisture against the grass, which can smother it and encourage fungal disease over winter. Rake or mulch leaves regularly rather than waiting for all of them to fall at once. A mulching mower can shred leaves into fine pieces that break down and actually feed the lawn, as long as the layer isn’t too thick.
Give the lawn one last mow and feed
Most cool-season lawns benefit from a final mow at a slightly shorter height than you used in summer, which helps prevent matting under snow. A fall fertilizer application, timed according to your product’s instructions and local climate, helps grass build stronger roots before winter dormancy — this is one of the most impactful lawn care tasks of the whole year in many climates.
Aerate and overseed bare or compacted spots
Fall is prime time for core aeration, which relieves soil compaction and lets water, air, and nutrients reach the roots. Follow up by overseeding thin or bare patches; cooler temperatures and typically more consistent rainfall give new grass seed a good head start before winter.
Cut back perennials — selectively
Many perennials can be cut back to a few inches above the ground once they’ve died back for the season, which tidies the garden and reduces places for pests and disease to overwinter. That said, consider leaving some seed heads and ornamental grasses standing through winter; they provide food and shelter for birds and add visual interest to an otherwise bare garden.
Plant spring-flowering bulbs
Tulips, daffodils, and crocuses all need a cold period to bloom properly, which makes fall the right time to get them in the ground — generally a few weeks before the ground freezes solid. Plant at the depth recommended on the packaging, typically about three times the bulb’s height.
Protect tender plants and containers
Bring any tropical or tender potted plants indoors before nighttime temperatures threaten frost. For in-ground plants that are marginally hardy in your area, a few inches of mulch around the base after the ground starts to cool helps insulate roots through winter. Empty and store ceramic or terra cotta containers, since trapped moisture can cause them to crack if it freezes.
Mulch garden beds
A fresh two- to three-inch layer of mulch over garden beds helps regulate soil temperature, retain moisture, and suppress weeds that would otherwise get a head start in spring. Keep mulch pulled a few inches back from tree trunks and shrub stems to avoid trapping moisture against the bark.
Clean and store garden tools and equipment
Clean soil and sap off hand tools, dry them thoroughly, and apply a light coat of oil to metal parts to prevent rust over winter. For gas-powered equipment like mowers and trimmers, run the tank dry or add a fuel stabilizer so leftover gasoline doesn’t degrade and gum up the engine. Drain and store hoses before the first freeze so they don’t crack.
Give trees and shrubs a final check
Walk the yard and look for dead or damaged branches, which are more likely to break under snow or ice load. Minor pruning can typically wait until the plant is fully dormant in late fall or winter, but if you spot a branch that’s clearly hazardous — hanging over a walkway or close to power lines — have a certified arborist handle it rather than tackling significant tree work yourself.
Quick checklist
- Keep up with raking or mulching leaves
- Final mow and fall fertilizer application
- Aerate and overseed thin areas
- Cut back perennials, but leave some for winter wildlife
- Plant spring bulbs
- Bring in tender plants; empty ceramic containers
- Refresh mulch in garden beds
- Clean and store tools; stabilize fuel in equipment
- Check trees and shrubs for hazardous branches
Spread across a few weekends, this list isn’t overwhelming — and the payoff is a lawn and garden that bounces back faster and healthier once the weather turns warm again.
For complex structural, electrical, gas, and other safety-critical work, consult a qualified professional and check local requirements.
