Fall Cleanup & Sprinkler Blowouts in Park City: The October Checklist

October in Park City is the in-between month. The aspens have turned, the mornings are crisp, and the first real snow is a matter of weeks away, not months.

What you do in the next few weeks decides two things: how your yard wakes up in spring, and whether your irrigation system survives the winter. Here is the October checklist we run through on every property before the freeze sets in.

Why October Is the Deadline, Not the Starting Line

At 7,000 feet, the first hard freeze can arrive with almost no warning, and a single deep freeze is all it takes to crack an irrigation line that still has water in it. Leaves left matting the lawn all winter invite snow mold. Branches left on beds end up buried and forgotten until spring.

None of this is complicated. It just needs to happen before the weather turns, because once the ground freezes, the window closes.

The October Checklist

1. Clear leaves and debris off the lawn and beds. A thick mat of wet leaves smothers grass over winter and creates the perfect conditions for snow mold. Mulch-mowing light leaf cover back into the lawn is fine; heavy layers need to be removed.

2. Do the final mow a little lower than summer. Around 2 to 2.5 inches is the sweet spot for going into winter in Park City. Too tall, and the grass mats down under snow. Too short, and the crowns are exposed.

3. Winterize the irrigation system with a proper blowout. This is the big one. Every line, valve, and head needs to be cleared with compressed air before the first hard freeze. Water left inside expands as it freezes and cracks pipes, valves, and backflow preventers. It is the most common and most expensive spring repair we see, and it is entirely preventable.

4. Aerate if you missed September. Early October still works. Pulling cores relieves summer compaction so water and nutrients reach the roots before dormancy.

5. Cut back perennials and tidy the beds. Cut back spent perennials, remove annuals that are done, and check mulch depth. Bare spots in beds are worth topping up now so roots have insulation through freeze-thaw cycles.

6. Feed the lawn one last time. A fall fertilization feeds root growth rather than top growth, so the lawn stores energy all winter and greens up faster in spring.

7. Mark edges and protect delicate surfaces before snow season. If your driveway gets plowed, snow stakes or markers along edges, walkways, and delicate bed borders save a lot of spring repair. Anything fragile near a plow path should be flagged now, while you can still see it.

8. Disconnect hoses and shut off outdoor water. Drain garden hoses, shut off exterior spigots from inside where possible, and drain backflow devices after the blowout.

The Most Expensive Thing to Skip

If you only do one thing on this list, make it the sprinkler blowout. A winterized system costs a fraction of what a single cracked mainline or backflow preventer costs to repair in spring, and freeze damage has a way of hiding until the system pressurizes in May.

 

When to Schedule It

Blowouts need to happen before the first hard freeze, which in the Park City area usually means mid-October. Our crew runs fall cleanups and sprinkler blowouts through October, and once the freeze hits, the schedule fills fast.
