What is core aeration?
Core aeration is the process of pulling small cylinders of soil, called plugs or cores, out of your lawn with a machine. Each hole opens up space in packed-down soil, giving grass roots room to grow and creating a direct path for water, oxygen, and fertilizer to reach them.
It is the method turf professionals and golf courses rely on, and it’s the only kind of aeration I do. Liquid aeration products are sprayed on and don’t remove any soil, so they can’t physically relieve compaction the way pulling a core does. If you’re paying for aeration, you should be able to see the plugs.
Why Davis County lawns need it
Much of Davis County sits on soils left behind by ancient Lake Bonneville: dense clay toward the Great Salt Lake and rocky, fast-draining ground up on the benches. Add new-construction fill, kids, pets, and weekly mowing, and most lawns here end up compacted within a few years.
Signs your lawn is compacted:
- Water puddles or runs off onto the sidewalk instead of soaking in
- Thin or patchy grass that doesn’t improve with more watering
- A spongy layer of thatch at the base of the grass
- Hard ground you can barely push a screwdriver into
- Brown spots that show up every July no matter what
Fall lawn aeration
For Utah’s cool-season grasses, like Kentucky bluegrass, perennial ryegrass, and tall fescue, fall is prime time. The soil is still warm from summer, the air is cooler, and the grass is actively building roots for winter. Aerating now helps your lawn recover from summer stress and sets it up for a fast, thick green-up next spring. It’s also the best time to add overseeding.
Spring lawn aeration
Spring aeration, once the ground has thawed and the lawn is waking up, is a great way to loosen soil that’s been packed down all winter. It helps your lawn soak up spring moisture and build roots before summer heat arrives. It’s especially helpful for clay-heavy or high-traffic yards. Want first pick of spring dates?

Before your appointment
- Water 1–2 days before. Moist soil gives deeper, cleaner plugs. Soggy soil is too much.
- Mow a little shorter than usual if you can.
- Tell me about hidden stuff: invisible dog fences, shallow lines, or landscape lighting.
- Unlock gates and secure pets. You don’t need to be home.
