As summer fades and cooler weather sets in across western Pennsylvania, it’s time to give your landscape the attention it needs to thrive through winter and emerge healthier next spring. Fall cleanup isn’t just about aesthetics—it’s essential for plant health, turf strength, and long-term landscape resilience.
At Dream Greener Lawn & Landscape, we serve homeowners across Pittsburgh and surrounding areas with seasonal services backed by science and tailored to our unique climate. This checklist outlines exactly what your Pittsburgh-area lawn and landscape need before winter—and why timing matters.
Remove Leaves Before They Suffocate Your Lawn
Why it matters:
Fallen leaves block sunlight and trap moisture, creating a breeding ground for fungal diseases like snow mold and smothering the grass beneath. According to the Penn State Extension, letting leaves accumulate can lead to dead patches, increased thatch, and difficulty with spring green-up.
What to do:
- Rake or mulch leaves weekly during peak fall drop
- Use a mulching mower if leaf volume is light
- Schedule professional leaf removal if you’re dealing with mature trees or heavy drop zones
Dream Greener Tip: Our cleanup crews remove leaves from turf, beds, hardscapes, and drainage areas to prevent long-term damage and ensure proper runoff during winter snow and rain.
Core Aerate Compacted Soil (Especially in Clay Areas)
Why it matters:
Much of the region sits on heavy, compacted clay soils. Aeration service in Pittsburgh lawns is a mechanical process that pulls soil plugs from the ground, opening up the lawn to oxygen, water, and nutrients. It also improves drainage and reduces thatch—both critical before winter.
According to Penn State University, fall is the best time to aerate cool-season lawns like Kentucky bluegrass, fescue, and ryegrass.
What to do:
- Schedule core aeration in early to mid-fall (Sept–Nov)
- Follow with overseeding using regionally appropriate seed blends (we use blue tag certified seed, the best on the market)
- Consider adding compost topdressing for better seed-to-soil contact
Dream Greener Tip: We tailor aeration depth and spacing based on your property’s turf health, slope, and soil condition. Overseeding right after gives new grass a head start before dormancy.
Cut Back Perennials and Prune Strategically
Why it matters:
Leaving some perennials up for winter interest is okay, but most herbaceous plants should be cut back to reduce disease and pest overwintering. Trees and shrubs also benefit from selective pruning—but timing and technique matter.
What to do:
- Cut back dead or diseased perennial foliage to 2–4” above the ground
- Remove faded blooms and dead wood from shrubs
- Wait until late winter or early spring for major structural pruning of trees
Caution: Never “top” trees or prune spring-flowering shrubs like lilac or forsythia in the fall—this removes next season’s blooms.
Clean and Mulch Landscape Beds
Why it matters:
Fall bed cleanup not only improves curb appeal but also prevents insect and disease carryover into next year. A fresh layer of mulch also insulates roots from winter freeze-thaw cycles, especially for shallow-rooted plants.
What to do:
- Assess the current landscape and identify areas that need improvement or changes.
- Remove spent annuals and fallen plant debris
- Add or refresh mulch (1–2” max) to stabilize soil temperatures
Dream Greener Tip: Our teams use organic, locally sourced mulch and can also apply compost to improve soil texture and biology.
Apply Final Fertilizer for Root Strength
Why it matters:
Fall fertilizer helps cool-season grasses like bluegrass and fescue store energy in their roots over winter, improving early spring green-up. The Penn State Extension recommends fall as the most important time to fertilize cool-season lawns.
What to do:
- Apply a slow-release nitrogen fertilizer between late September and early November
- Avoid quick-release or high-nitrogen fertilizers that promote top growth in cold weather
- Follow soil test recommendations whenever possible
Dream Greener Tip: Our Pittsburgh lawn care programs include a custom-blended fall fertilizer that promotes deeper roots without pushing late-season leaf growth.
Check for Drainage Problems Before Snowmelt
Why it matters:
Pooling water around your home or landscape can cause damage during winter freeze-thaw cycles. Proper grading and drainage ensure excess water drains away from foundations and plantings.
What to do:
- Inspect gutters, downspouts, and French drains for blockages
- Ensure downspouts extend at least 3–5 feet from the foundation
- Identify areas of turf that remain soggy after rain
Dream Greener Tip: We offer drainage assessments and can install or repair dry creek beds, catch basins, or swales before winter weather sets in.
Protect Young or Vulnerable Plants
Why it matters:
New plantings, shallow-rooted shrubs, and broadleaf evergreens (like boxwood or rhododendron) may suffer from desiccation, frost heave, or salt damage during Pittsburgh’s harsh winters.
What to do:
- Apply 2–3” mulch around root zones (not touching trunks)
- Water thoroughly before ground freeze
- Wrap trunks or use burlap screens to shield from wind and road salt
Clean and Store Outdoor Equipment
Why it matters:
Lawn mowers, string trimmers, and garden tools last longer when cleaned and stored properly. This also prevents the spread of diseases or weeds in spring.
What to do:
- Empty fuel or add stabilizer to engines
- Clean blades, remove debris, and sharpen as needed
- Store in a dry, covered space away from moisture
Schedule a Professional Lawn & Landscape Analysis
Why it matters:
A custom evaluation helps you understand your property’s specific needs. At Dream Greener, we look at soil condition, turf density, light exposure, compaction, drainage, and plant health so you get a tailored fall cleanup plan. Fall is the ideal time to assess and address lawn issues before winter stress sets in—and when fixes like aeration and seeding are most effective.
Frequently Asked Questions
When should I schedule fall cleanup in Pittsburgh?
Early to mid-fall (late September through early November) is ideal. Timing varies depending on leaf drop and the services you need.
Can I skip fall cleanup and just start fresh in spring?
Skipping cleanup leads to matted leaves, fungal disease, and a mess to fix later. Fall prep = spring success.
How much does fall cleanup cost?
It depends on property size, services included (e.g., aeration, leaf removal, bed prep), and add-ons like compost. Request a quote here.
