📅 When to Plant Runner Bean?

Runner Bean (also known as Stangenbohne) belongs to the Vegetables category and is suitable for outdoor planting from Late Spring onwards.

Use the Growing Temperature Sum (GTS) as a guide: Runner Bean can be safely transplanted once the local GTS has passed the threshold for Late Spring and no frost is expected. GrowPilot.guide calculates the current GTS for your location automatically.

🗓️ Tip: Always check the 10-day weather forecast before planting outdoors. The GTS is a helpful guide but does not replace a frost check for your specific area.

❄️ Frost Sensitivity & Protection

Runner Bean cannot tolerate any frost whatsoever. Even light ground frost (−1°C) can cause complete plant loss. Only transplant outdoors when night temperatures are consistently above 10°C and no frost is forecast for the next two weeks.

What to do in case of late frost?

❄️ Late frost risk: In many temperate climates, late spring frosts can occur well into May. Always check the 10-day forecast before planting Runner Bean outdoors.

🌡️ Optimal Temperatures

Runner Bean grows best at daytime temperatures between 18°C and 28°C. Night temperatures should not fall below 10°C.

🍄 Mold & Rain Tolerance

Runner Bean shows moderate sensitivity to mold. Take precautions during extended rain or very high humidity – good ventilation is important.

Rain sensitivity: Medium – Moderate rain is tolerated, but waterlogging should be avoided.
