More cold-sensitive than oregano – only after last frost.
Marjoram (also known as Majoran) belongs to the Herbs category and is suitable for outdoor planting from Mid Spring onwards.
Use the Growing Temperature Sum (GTS) as a guide: Marjoram 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.
Marjoram is frost-sensitive and should only be planted out after the last frost date for your area. Minimum night temperature: 8°C. Brief cold snaps below 0°C can cause damage.
Marjoram grows best at daytime temperatures between 16°C and 30°C. Night temperatures should not fall below 8°C.
Marjoram is relatively robust against mold and tolerates wetter conditions well. Still, always avoid waterlogging.
Rain sensitivity: Medium – Moderate rain is tolerated, but waterlogging should be avoided.
