July checklist
- Water mature trees deeply, to about 18 inches, out to the canopy edge
- Check mulch, 2 to 4 inches (ISA), kept off the trunk
- Look for scorched, wilted or thinning crowns
- Keep leaves, needles and woodpiles out of the first 5 feet around the house
- Call 811 before any stump grinding
- Have dead limbs over structures removed
- Keep ladder fuels pruned under larger trees
Highs average 93.9 F at the Reno airport and 94.2 F at Fallon, while Glenbrook on the Tahoe shore tops out at 76.6 F.
July weather at five stations
Fallon has the lowest July precipitation at 0.12 inches, and Carson City has 0.18. The Reno airport's 77.2 F mean is the warmest of its year, and Minden averages 70.1 F against Glenbrook's 63.1 F. No station records snow.
| Station (elevation, ft) | Mean temp (F) | Precip (in.) | Snow (in.) |
|---|---|---|---|
| Reno airport (4,410) | 77.2 | 0.20 | 0.0 |
| Carson City (4,761) | 72.1 | 0.18 | 0.0 |
| Minden (4,709) | 70.1 | 0.25 | 0.0 |
| Glenbrook (Tahoe) (6,350) | 63.1 | 0.32 | no normal |
| Fallon (3,965) | 74.7 | 0.12 | 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
Trees draw hard on stored soil water. Leaf scorch, curling and early yellowing can follow a hot spell. Siberian elm tolerates cold and dry ground better than most shade trees, but old trees still shed limbs. See drought stress and dieback.
Jobs that fit July
Watering is the main job, along with checking that mulch still covers the root zone. Dead wooding, hazard pruning and removal fit any month. For large removals near a house, wires or fences, a crane can reduce time and impact on the surroundings. Stump grinding is fine in summer; call 811 first so marked lines are known before anyone digs.
Keep fire from the door
Dry vegetation is the fire concern now. Living With Fire keeps Zone 0, the first 5 feet, free of woodpiles, combustible mulch, dead leaves and needles, and describes Zone 1 as lean, clean and green. Pine needles in gutters and on roofs are fuel. Remove them, and keep firewood well away from the building.
Valley versus lake
The Tahoe shore runs about 17 degrees cooler on an average July afternoon, 76.6 F against 93.9 F at the Reno airport, but its dry season is real: Glenbrook gets 0.32 inches. The agencies set the rules, not us: TRPA permits apply to live trees over 14 inches DBH. For anything overhead or near a structure, call 775.232.8243. Estimates are free, and a certified arborist assesses every job before work begins.
