Lawn Aeration & Overseeding
Fall Core Aeration and Overseeding Are the Keys to a Thick, Healthy Lawn in Eastern Massachusetts
If a lawn gets just one service a year, lawn aeration is the one we'd recommend. Core aeration pulls small plugs of soil so air, water and nutrients can reach the roots, and paired with overseeding it's one of the most effective treatments for thin or compacted turf in our climate. The fall schedule fills quickly, so it's worth booking early.
We provide weekly and biweekly mowing across Newton, Wellesley, Weston, and all surrounding towns, and we'd be glad to price the season for you.
What Core Aeration Does
Soil under a lawn compacts over time from foot traffic, mowing equipment and, on many properties here, construction from years ago. Compacted soil holds less air and water and resists root growth. Grass growing in it stays shallow-rooted, which is why it's the first to turn brown in a dry August.
Core aeration removes plugs of soil and leaves open channels behind. Roots grow into them, water soaks in instead of running off, and fertilizer and seed reach the root zone. The plugs left on the surface break down within a couple of weeks.
We use core aerators, which pull plugs, rather than spike aerators, which push soil sideways and can add to compaction.
Why Overseeding Goes With It
A freshly aerated lawn is an excellent seedbed. Seed falls into the open holes, makes good contact with the soil and germinates at a much better rate than seed spread on an undisturbed surface.
It's also a chance to introduce improved grass. Turf varieties have come a long way, and a lawn seeded twenty years ago is running on older genetics. Fine fescues for shaded areas, or turf-type tall fescue for drought tolerance, can change how the lawn performs over time.
Early Fall Is the Window
Late August through September is ideal, and the timing matters more than people expect.
The soil is still warm, which helps seed germinate. Air temperatures are cooling, which eases stress on new seedlings. Rainfall is more reliable, crabgrass has finished for the year, and there's enough season left for new grass to establish before the ground freezes.
Spring aeration and seeding is possible, but the results aren't as strong, because seedlings head straight into summer heat and compete with crabgrass. For a once-a-year service, September is the time.
Mark Irrigation and Private Lines
Aeration equipment pulls plugs several inches deep, which can reach shallow irrigation lines, invisible fence wire and lighting cable. Public utility marking doesn't cover private lines, so we'll ask you to mark them before we arrive. If we service your irrigation, we can help locate the heads.
Common Questions
How often should a lawn be aerated?
Once a year for most properties here, since soil in this area tends to compact. Lawns with heavy clay or lots of use benefit every year. Sandy, lightly used lawns can go every other year.
Do I need to water after seeding?
Yes, and it's the most important step after the service. New seed needs consistently moist soil until it germinates, which means light, frequent watering. Once the grass is established, switch to deeper, less frequent watering.
What should I do before you arrive?
Mark irrigation heads, invisible fence and any other private lines. Mowing a little shorter than usual helps the seed reach the soil, and watering the day before helps if it's been dry.
How long before new grass fills in?
Germination takes one to three weeks depending on the variety and temperature. You'll see real fill-in over four to six weeks, and the full result the following spring.
