Can rape be planted after the first frost?

Rape can be planted in the first frost. The lowest temperature of rape seed germination is 4-6℃, and it can germinate for 4 days at 20-25℃. First frost means there will be frost. The national average temperature before and after the first frost is 10℃-20℃, and the first frost is suitable for planting rape.

Rape is suitable for growing in low temperature areas. Spring European rape, which was born more than 400 years ago, has the shortest growth cycle. Semi-winter European rape was born in China more than 70 years ago, with a wide planting area. After many generations of breeding, several varieties with different growth conditions and characteristics have been hybridized. Rape is strong in winter, and timely early sowing is beneficial to increase the effective growth period and photosynthetic products in winter, which lays the foundation for multi-branching and increasing the number of pods.
