Large-leafed – wind-sensitive, out after frost.
Courgette/Zucchini (also known as Zucchini) belongs to the Vegetables category and is suitable for outdoor planting from Late Spring onwards.
Use the Growing Temperature Sum (GTS) as a guide: Courgette/Zucchini can be safely transplanted once the local GTS has passed the threshold for Late 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.
