📅 When to Plant Thyme?

Thyme (also known as Thymian) belongs to the Herbs category and is suitable for outdoor planting from Mid Spring onwards.

Use the Growing Temperature Sum (GTS) as a guide: Thyme 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

Thyme is frost-hardy and withstands moderate freezing temperatures well. Can be planted early in spring once the ground is workable. Ideal minimum night temperature: 0°C.

🌡️ Optimal Temperatures

Thyme grows best at daytime temperatures between 10°C and 35°C. Night temperatures should not fall below 0°C.

🍄 Mold & Rain Tolerance

Thyme 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.
