Core aeration pulls small plugs of soil out of your lawn so air, water and nutrients can reach the roots more easily. For most lawns in the Salt Lake Valley, timing it right makes a noticeable difference.
Why Aeration Helps
Foot traffic, mowing equipment and our region’s often clay-heavy soils can compact the ground over time. Compacted soil makes it harder for water to soak in and for roots to grow deep.
Core aeration loosens the soil and can help break up thatch – the layer of dead stems and roots between the grass and the soil. The plugs left on the surface break down on their own after a few mowings and waterings.
The Best Time to Aerate in Utah
Most Utah lawns are cool-season grasses like Kentucky bluegrass. These grasses recover fastest when they are actively growing and temperatures are mild, which is why spring and early fall are generally recommended.
Early fall is often the favorite: the soil is still warm, nights are cooler, and the lawn has time to recover before winter. It is also a good time to overseed thin areas. Spring aeration works well too, once the soil has thawed and dried enough to work.
Try to avoid aerating during the heat of mid-summer, when the lawn is already stressed, or when the ground is frozen or waterlogged.
Signs Your Lawn May Need Aeration
- Water puddles or runs off instead of soaking in.
- The soil feels hard and a screwdriver is difficult to push into the ground.
- Grass is thinning in high-traffic areas such as paths and play areas.
- A spongy feel underfoot, which can point to a thick thatch layer.
- It has been a few years since the lawn was last aerated.
How to Prepare
- Water the lawn a day or two before if the soil is dry – moist soil lets the tines pull cleaner plugs.
- Flag sprinkler heads, shallow lines and invisible pet fences so they are not damaged.
- Mow beforehand at your normal height.
- After aerating, leave the plugs in place and resume normal watering and mowing.

Frequently Asked Questions
How often should I aerate my lawn?
Many lawns benefit from aeration about once a year, and heavily used or compacted lawns sometimes more. Lightly used lawns on looser soil may need it less often.
Should I remove the soil plugs after aeration?
No. The plugs usually break down on their own within a couple of weeks and return soil and organic matter to the lawn.
