Robust – sow early, harvest quickly.
Spring Onion (also known as Frühlingszwiebel) belongs to the Vegetables category and is suitable for outdoor planting from Early Spring onwards.
Use the Growing Temperature Sum (GTS) as a guide: Spring Onion can be safely transplanted once the local GTS has passed the threshold for Early 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.
