A little work in fall pays off when the snow melts. Here is a straightforward checklist to help your Salt Lake County lawn come through winter in good shape.
1. Keep Mowing Until Growth Stops
Cool-season grass keeps growing into fall. Continue mowing as needed, and lower the height slightly for the last cut or two. Very long grass going into winter can mat down under snow; scalping it too short can stress it.
2. Clear the Leaves
A thick layer of wet leaves can block light and trap moisture, which can weaken grass and encourage disease. Rake, blow or mulch leaves regularly instead of waiting for one big cleanup.
3. Consider Fall Aeration and Fertilizing
Early fall is a good time to aerate compacted lawns. A fall fertilizer application is generally considered one of the most useful feedings of the year for cool-season grass, helping roots store energy for spring. Follow product label rates.
4. Winterize Your Sprinklers
Water left in sprinkler lines can freeze, expand and crack pipes, valves and heads. Shut off the water supply and have the lines drained or blown out before hard freezes set in – often in October or early November along the Wasatch Front, though it varies each year.
5. Plan for Snow and Ice
Prefer not to shovel? See our snow and ice removal service.
- Mark the edges of driveways and walkways with stakes so shovels and plows stay off the lawn.
- Avoid piling snow in the same spot on the lawn all winter.
- Use ice melt sparingly near grass and planting beds, and sweep up excess once the ice is gone.
6. Water During Dry, Mild Spells
Utah winters can have long dry stretches. If there is no snow cover and the ground is not frozen, a light watering on a mild day can help lawns, trees and shrubs avoid winter dry-out. Use a hose rather than restarting a winterized sprinkler system.
Frequently Asked Questions
When is the last mow of the year in Salt Lake County?
Usually when the grass stops growing in late fall, often in late October or November depending on the weather.
Is it too late to fertilize in November?
It depends on the weather and the product. Many fall programs apply fertilizer while grass is still green and growing; check the label or ask us about your lawn.
