# Tree care in September in Northern Nevada

September is the month to finish fire-season work and set up winter: temperatures fall about 8 degrees at the Reno airport from August, precipitation stays near 0.2 inches, and the first storms are weeks away.

The month's typical rain, snow and temperatures at five weather stations:

## September weather normals

| Station | Elevation (ft) | Precipitation (in) | Snowfall (in) | Mean temperature (F) | Average low (F) |
|---|---|---|---|---|---|
| Reno airport | 4,410 | 0.21 | 0.0 | 67.0 | 50.3 |
| Carson City | 4,761 | 0.24 | 0.0 | 63.1 | 45.6 |
| Minden | 4,709 | 0.21 | 0.0 | 61.8 | 40.2 |
| Glenbrook | 6,350 | 0.28 | not reported | 58.2 | 45.4 |
| Fallon | 3,965 | 0.19 | 0.0 | 63.6 | 43.9 |

Source: [NOAA NCEI U.S. Climate Normals 1991-2020, monthly](https://www.ncei.noaa.gov/products/land-based-station/us-climate-normals). Monthly normals for September at five stations. Glenbrook publishes no snowfall normal.

## September checklist

- Finish defensible space work while the ground is open
- Inspect large trees for cracks, dead limbs and lean
- Book removals, crane work and stump grinding before winter
- Call about firewood availability and pricing early
- Keep watering until the soil freezes
- Clear leaves and needles from Zone 0 as they drop
- Ask whether your address is on a snow service route

The Reno airport drops from a 75.1 F August mean to 67.0 F in September, and Carson City falls from 70.2 F to 63.1 F. The ground is still dry and open, which makes this a good month for clearing and inspection.

## September weather at five stations

Precipitation stays near 0.2 inches at every valley station: 0.21 at the Reno airport and Minden, 0.24 at Carson City and 0.19 at Fallon. Glenbrook has 0.28 inches. No station records snow in September.

| Station (elevation, ft) | Mean temp (F) | Precip (in.) | Snow (in.) |
|---|---|---|---|
| Reno airport (4,410) | 67.0 | 0.21 | 0.0 |
| Carson City (4,761) | 63.1 | 0.24 | 0.0 |
| Minden (4,709) | 61.8 | 0.21 | 0.0 |
| Glenbrook (Tahoe) (6,350) | 58.2 | 0.28 | no normal |
| Fallon (3,965) | 63.6 | 0.19 | 0.0 |

Station normals, not town averages. NOAA flags Glenbrook's temperature normals as reduced completeness and publishes no snowfall normal there.

## What the trees are doing

Cooler nights start to slow growth, and some species begin to color and drop leaves. Trees are still using water. Do not stop irrigating because the weather has cooled: keep watering until the soil freezes, then follow University of Nevada, Reno Extension's winter schedule.

## Jobs that fit September

Finish the defensible space work you started in spring. See [defensible space work to finish before winter](https://battleborntreeservice.com/blog/defensible-space-before-winter/). Large removals and crane work are easier to schedule before the first storms. A walk with a certified arborist now, while leaves are on, shows which limbs carry the most weight over a roof or drive. Hazards and dead wood come out any time.

## Firewood and snow, early

Firewood bought in September has months to season. Penn State Extension puts drying at 6 to 12 months to reach about 20 percent moisture, which is why timing matters. Call the office for availability and pricing. If you want snow service, call before the season and ask whether your address is on the route. See [how to season and stack firewood](https://battleborntreeservice.com/guides/how-to-season-and-stack-firewood/) and [firewood season in Carson City](https://battleborntreeservice.com/blog/firewood-season-2026-carson-city/).

## Valley versus lake

Glenbrook falls from 63.2 F in August to 58.2 F, a 5-degree drop, against 8 at Reno, so autumn arrives more slowly on the lake. TRPA permits and fire district rules still govern removals in the Tahoe Basin. Call [775.232.8243](tel:775.232.8243) to book fall work; the phone is staffed seven days a week and estimates are free.

## Questions people ask

Still have a question? Call [775.232.8243](tel:775.232.8243). Phones are answered seven days a week.

### Should I keep watering trees in September?

Yes, until the soil freezes. Winter watering then follows University of Nevada, Reno Extension's schedule.

### When should I order firewood?

Early. Firewood generally needs 6 to 12 months to dry, so ask the office what is available. We do not publish prices or terms.

### Is September a good time to do defensible space work?

Yes. The ground is open and summer fuel has dried. Your fire district may have its own rules.
