The flowers will be in full bloom in mid-March and will wither around the Qingming Festival. But if the spring temperature continues to drop this year, the rapeseed flowers may not bloom until mid-March.

Rapeseed flowering process

The period from when rapeseed sprouts to 45 days is called the seedling stage. During this period, the whole plant is in a rosette shape and has no stem.

After the flowers wither, only a pod is left and the plant will gradually wither.
