1. Soil: it is best to use loose clay loam for cultivating paddy mustard, and it is better to use neutral soil.
2. Light: it likes sunshine. During the growth period, it should have enough light, which can promote photosynthesis. If not enough light, it will lead to poor growth of stems and leaves.
3. Temperature: to give it a growth environment of 15-25 ℃, temperature control at 20 ℃ will be more conducive to its growth. If the temperature is lower than 10 ℃ or higher than 30 ℃, it will grow slowly. If the temperature continues to be low or high, the plant may die.
