When to Plant Potatoes in Virginia: Spring and Fall Dates by Zone
One Virginia calendar, one crop: potatoes, with the source’s dates left as printed and NOAA frost dates for Roanoke Regional Airport, Charlottesville Airport, and Richmond International Airport.

Figures checked against their sources on ; next check .
Open Virginia Cooperative Extension’s calendar to the potato line and you find 6 zones, each with its own spring and fall entries. Zone 6a starts latest, on April 1, while Zone 8a starts on February 20: 40 days between the two.
Potatoes: the Virginia table
Table 5 of the same guide puts potatoes at 10 plants per person, with 1 planting in spring and summer and none in fall.
| Zone | Spring planting | Fall planting |
|---|---|---|
| Zone 6a | April 1-June 1 | Not recommended |
| Zone 6b | March 20-June 1 | Not recommended |
| Zone 7a | March 10-May 20 | Not recommended |
| Zone 7b | March 1-May 10 | Not recommended |
| Zone 8a | Feb 20-April 10 | Not recommended |
| Zone 8b | Feb 20-April 1 | Not recommended |
Reading the Virginia Cooperative Extension table
The guide warns that Virginia’s mountainous topography creates a diversity of hardiness zones over a small area, and it gives Roanoke County as an example: four zones, with a 30-day planting difference between them. Its first table prints the median last spring frost and first fall frost as a range for each zone, for example April 5-15 and October 25-November 5 in zone 7b.
Where a cell reads “Not recommended”, the source gives no planting window for that season, and this page leaves it that way.
Do potatoes get an indoor start?
The general sources have little to say about starting potatoes indoors, since UNH has them go straight into the ground.
Potatoes are planted as seed potatoes, not seedlings, so none of the saved seed-starting tables applies; UNH’s timing is counted from the last frost instead.
UNH’s own timing for potatoes is 1 to 2 weeks before the last frost, so Virginia’s printed window and UNH’s rule of thumb can be set side by side.
| Source | What it says |
|---|---|
| University of New Hampshire | Not started indoors; plant seed potatoes 1 to 2 weeks before the last frost |
Where the frost dates fall in Virginia
The dates come straight from NOAA’s frost and freeze normals at the 32°F threshold; the frost dates tool shows earlier and later odds for the same stations.
Virginia Cooperative Extension does not say which of its zones each city falls in, so the table does not guess.
| Station | Last spring 32°F | First fall 32°F | Region in the calendar |
|---|---|---|---|
| Roanoke Regional Airport, Virginia | April 3 | November 1 | Not stated by the source |
| Charlottesville Airport, Virginia | April 3 | November 1 | Not stated by the source |
| Richmond International Airport, Virginia | April 3 | November 4 | Not stated by the source |
| Norfolk International Airport, Virginia | March 17 | November 23 | Not stated by the source |
| Washington DC Dulles Airport, Virginia | April 15 | October 24 | Not stated by the source |
Worked example
Start from Roanoke Regional Airport: the station’s median last spring freeze is April 3, and its median first fall freeze is November 1.
The calendar does not say which zone Roanoke Regional Airport belongs to, so set the date against the rows at each end. Zone 8a opens February 20, 42 days before that date; Zone 6a opens April 1, 2 days before it.
The offsets will shift by a few days with every revision of the normals, so use them as a rough guide to which row to trust and not as a deadline.
Before you rely on these dates
The guide says actual last and first killing frost dates vary with local conditions and from year to year, and invites gardeners to favor earlier or later dates within a range.
Treat the table as a starting range and look at the ten-day forecast before setting out anything tender.
