The current average 2-inch soil temperature across Virginia is 75°F. Readings range from 68°F to 79°F, from 5 USDA and NOAA monitoring stations. Soil across Virginia is running 3°F above the seasonal normal of 71°F for mid-September, based on 5 of 5 stations with historical records. Virginia spans USDA hardiness zones 7a to 8b, cool-season grass country. Last updated September 14, 2026.
Soil across Virginia is cooling off its summer peak at an average of 75°F at 2 inches. The fall poa annua pre-emergent window is in play as readings fall through the 65–70°F band, and cool-season overseeding follows close behind.
Virginia spans both grass families: cool-season lawns are more common toward the cooler, northern parts of the state and at elevation, warm-season lawns toward the warmer south.
For cool-season lawns (fescue, bluegrass, ryegrass), fall is the best time to plant grass seed in Virginia, with spring the second choice: fall seedlings face less weed competition and mature before summer heat. The window opens as 2-inch soil falls back through 70°F, and germination slows sharply once soil drops below 50°F, typically around November 20.
Spring is the second choice: the window opens when soil first holds 50°F and narrows as soil passes 65°F, typically by May 15.
For warm-season lawns (bermuda, zoysia, St. Augustine), the best time to plant grass seed in Virginia is late spring into early summer, when soil is warming and a full growing season lies ahead. The window opens when 2-inch soil reaches 65°F and keeps rising, and closes as soil cools back through 65°F, typically around October 8.

|---|---|---|---|
| Eastern Virginia | March 11 | September 30 | 2 |
| Central Virginia | March 23 | September 9 | 3 |
Fall seeding also needs a stop date: new seedlings want about six weeks of growth before frost arrives. Your city page estimates the last safe seeding date from its nearest station: see when to plant in Roanoke, when to plant in Richmond or when to plant in Arlington. Readings current through September 14, 2026: Virginia averages 75°F at 2 inches right now; the Current Planting Conditions section above reads that number against the season.
Typical dates are computed from historical 2-inch soil temperature averages at 5 monitoring stations in Virginia; your own window depends on your nearest station's readings.

Fall is the best time to overseed a thin lawn.
Core aeration relieves compaction, but timing decides whether the lawn recovers in a week or struggles for a month.
Apply fall pre-emergent when 2-inch soil falls back through 70°F and keeps declining; that crossing is when poa annua and winter annual weeds sprout.
Fall is when broadleaf herbicide works hardest.
The current average 2-inch soil temperature across Virginia is 75°F. Readings range from 68°F to 79°F depending on location and elevation, from 5 USDA and NOAA monitoring stations. Soil across Virginia is running 3°F above the seasonal normal of 71°F for mid-September, based on 5 of 5 stations with historical records.
Apply pre-emergent herbicide when soil at 2 inches reaches 55°F for several consecutive days. Timing varies across Virginia, so check your city's page for station-specific readings and the pre-emergent timing recommendation.
Virginia spans USDA hardiness zones 7a to 8b, cool-season grass country. For cool-season grasses (fescue, bluegrass), the fall window typically opens around September 18 and the spring window around March 11; for warm-season grasses (bermuda, zoysia), the window typically opens around May 15, based on historical 2-inch soil temperature averages at 5 in-state stations. Timing varies by location, so check your city's planting window for the dates specific to your area.
