📅 When to Plant Pak Choi?

Pak Choi (also known as Pak Choi) belongs to the Vegetables category and is suitable for outdoor planting from Mid Spring onwards.

Use the Growing Temperature Sum (GTS) as a guide: Pak Choi 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.

❄️ Frost Sensitivity & Protection

Pak Choi tolerates light frost down to about −3°C. Extended cold periods or hard frosts are harmful. Once night temperatures stay above 5°C, it is safe to plant outdoors.

🌡️ Optimal Temperatures

Pak Choi grows best at daytime temperatures between 14°C and 24°C. Night temperatures should not fall below 5°C.

🍄 Mold & Rain Tolerance

Pak Choi shows moderate sensitivity to mold. Take precautions during extended rain or very high humidity – good ventilation is important.

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