📅 When to Plant Broad Bean?

Broad Bean (also known as Dicke Bohne) belongs to the Vegetables category and is suitable for outdoor planting from Early Spring onwards.

Use the Growing Temperature Sum (GTS) as a guide: Broad Bean can be safely transplanted once the local GTS has passed the threshold for Early 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

Broad Bean is frost-hardy and withstands moderate freezing temperatures well. Can be planted early in spring once the ground is workable. Ideal minimum night temperature: 2°C.

🌡️ Optimal Temperatures

Broad Bean grows best at daytime temperatures between 10°C and 22°C. Night temperatures should not fall below 2°C.

🍄 Mold & Rain Tolerance

Broad 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.
