It prefers warm climates, is heat-tolerant, and not cold-tolerant. The optimal growth temperature is between 25-30°C, with slow growth below 20°C, and it will wilt if exposed to frost. If the temperature exceeds 30°C, the product quality tends to decline. The plant is a short-day species and tends to bolt and flower under high temperatures and long daylight hours in autumn. It is not particularly picky about soil but has strong nutrient absorption. It thrives in loose, fertile soils rich in organic matter, which produce higher yields and better quality. It also has some cold resistance and drought tolerance.
