State Gardening lists frost dates, planting zones and planting dates for every county in the states it covers. All figures come from public sources: NOAA climate normals, the USDA plant hardiness zone map and the land-grant university extension service in each state. Each page names its sources and links to them.
Where a publication gives dates relative to frost, or by region or zone, the site applies them to each county as the publication describes and says so on the page. Nothing is estimated beyond that.
State Gardening is not affiliated with NOAA, USDA or any university. For advice on your own garden, contact your county extension office, listed on each county page.
