📅 When to Plant Plum?

Plum (also known as Pflaume) 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: Plum 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

Plum 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

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

🍄 Mold & Rain Tolerance

Plum is sensitive to mold and high humidity. Ensure good air circulation during prolonged wet or humid weather. Space plants well and allow leaves to dry after rain.

Rain sensitivity: High – Prolonged rain can cause damage – protection with a film cover or roof overhang is recommended.
