Perennial – slow to re-sprout in spring.
Tarragon (also known as Estragon) belongs to the Herbs category and is suitable for outdoor planting from Mid Spring onwards.
Use the Growing Temperature Sum (GTS) as a guide: Tarragon 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.
Tarragon tolerates light frost down to about −3°C. Extended cold periods or hard frosts are harmful. Once night temperatures stay above 4°C, it is safe to plant outdoors.
Tarragon grows best at daytime temperatures between 14°C and 28°C. Night temperatures should not fall below 4°C.
Tarragon 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.
