More sensitive than broccoli – protect heads from frost.
Cauliflower (also known as Blumenkohl) belongs to the Vegetables category and is suitable for outdoor planting from Early Spring onwards.
Use the Growing Temperature Sum (GTS) as a guide: Cauliflower 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.
Cauliflower tolerates light frost down to about −3°C. Extended cold periods or hard frosts are harmful. Once night temperatures stay above 5°C, it is safe to plant outdoors.
Cauliflower grows best at daytime temperatures between 14°C and 24°C. Night temperatures should not fall below 5°C.
Cauliflower 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.
