Frost improves the flavour – almost impossible to kill.
Kale (also known as Grünkohl) belongs to the Vegetables category and is suitable for outdoor planting from Mid Spring onwards.
Use the Growing Temperature Sum (GTS) as a guide: Kale 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.
Kale is very frost-hardy and survives even hard freezes. Can be planted in late winter or very early spring. Minimum night temperature: -5°C (ideal, not a strict requirement).
Kale grows best at daytime temperatures between 8°C and 20°C. Night temperatures should not fall below -5°C.
Kale is relatively robust against mold and tolerates wetter conditions well. Still, always avoid waterlogging.
Rain sensitivity: Low – Relatively rain-tolerant – good drainage is sufficient.
