Perennial and frost-hardy – great for beginners.
Lemon Balm (also known as Zitronenmelisse) belongs to the Herbs category and is suitable for outdoor planting from Mid Spring onwards.
Use the Growing Temperature Sum (GTS) as a guide: Lemon Balm 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.
Lemon Balm 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.
Lemon Balm grows best at daytime temperatures between 14°C and 28°C. Night temperatures should not fall below 4°C.
Lemon Balm is relatively robust against mold and tolerates wetter conditions well. Still, always avoid waterlogging.
Rain sensitivity: Low – Relatively rain-tolerant – good drainage is sufficient.
