Growing Cucumbers in Tennessee
Cucumbers in Tennessee's Climate
Your long, hot season is excellent for cucumbers. Plant early (transplant in March-April) for a long harvest before late-summer pest pressure builds. A second planting in August for fall harvest is productive and often has less disease pressure than midsummer. In the Gulf states, downy mildew is the primary disease concern — choose resistant varieties.
Soil Considerations for Tennessee
Clay soils over limestone in Middle Tennessee. Rich river bottom soils in west. Rocky mountain soils in east. Make sure soil has warmed to at least 60°F before planting cucumbers outside.
Tennessee Climate & Growing Season
Mild four-season climate. Hot, humid summers. Adequate rainfall. Good growing season for wide variety of crops. Cucumbers cannot tolerate any frost, so wait until all frost danger has passed before transplanting outside. Watch local forecasts carefully in spring.
Growing season length varies across Tennessee: East Tennessee (6a, 6b, 7a) has a last frost around Apr 5 - Apr 25, while West Tennessee (7a, 7b) sees frost end around Mar 25 - Apr 10. This difference matters for cucumbers — transplant timing shifts by several weeks across the state.
