Loves dry conditions – avoid waterlogging.
Rosemary (also known as Rosmarin) belongs to the Herbs category and is suitable for outdoor planting from Mid Spring onwards.
Use the Growing Temperature Sum (GTS) as a guide: Rosemary 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.
Rosemary 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.
Rosemary grows best at daytime temperatures between 12°C and 35°C. Night temperatures should not fall below 2°C.
Rosemary is relatively robust against mold and tolerates wetter conditions well. Still, always avoid waterlogging.
Rain sensitivity: High – Prolonged rain can cause damage – protection with a film cover or roof overhang is recommended.
