📅 When to Plant Corn/Maize?

Corn/Maize (also known as Mais) belongs to the Vegetables category and is suitable for outdoor planting from Late Spring onwards.

Use the Growing Temperature Sum (GTS) as a guide: Corn/Maize 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.

❄️ Frost Sensitivity & Protection

Corn/Maize cannot tolerate any frost whatsoever. Even light ground frost (−1°C) can cause complete plant loss. Only transplant outdoors when night temperatures are consistently above 10°C and no frost is forecast for the next two weeks.

What to do in case of late frost?

❄️ Late frost risk: In many temperate climates, late spring frosts can occur well into May. Always check the 10-day forecast before planting Corn/Maize outdoors.

🌡️ Optimal Temperatures

Corn/Maize grows best at daytime temperatures between 18°C and 32°C. Night temperatures should not fall below 10°C.

🍄 Mold & Rain Tolerance

Corn/Maize is relatively robust against mold and tolerates wetter conditions well. Still, always avoid waterlogging.

Rain sensitivity: Low – Relatively rain-tolerant – good drainage is sufficient.
