📅 When to Plant Blueberry?

Blueberry (also known as Heidelbeere) belongs to the Fruit & Berries category and is suitable for outdoor planting from Mid Spring onwards.

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

Blueberry tolerates light frost down to about −3°C. Extended cold periods or hard frosts are harmful. Once night temperatures stay above 2°C, it is safe to plant outdoors.

🌡️ Optimal Temperatures

Blueberry grows best at daytime temperatures between 14°C and 28°C. Night temperatures should not fall below 2°C.

🍄 Mold & Rain Tolerance

Blueberry 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.
