Pteridium aquilinum is a high-temperature and low-temperature tolerant plant, which can still grow at the temperature of 32℃, and its roots can safely overwinter at the temperature of -35℃. It has strong resistance and adaptability, but it likes the cool and humid climate best, so the growing season is generally around April, that is, from Qingming to Grain Rain.
However, due to local differences, the specific growth time may vary. For the southern region where the temperature rises rapidly, the growth rate may be faster, while for the northern region where the temperature rises slowly, the growth time may be slower.
The picking time of bracken in Kunming is usually from March to June.
