When to plant cucumbers
Plant cucumbers after the last frost has passed and the soil has warmed to 70°F.
The window: Set out in the garden 1-2 weeks after the last frost, or plant seed when the soil warms to 70°F.
- Seeds will not germinate at soil temperatures below 50°F.
- Cucumbers grow best at temperatures between 75 and 85°F.
- Cucumbers are sensitive to cold and can be killed by even a light frost.
The mistake to avoid: Do not plant before the soil reaches 70°F, since seeds will not germinate below 50°F and a light frost can kill the plant.
