Daylily is barren and drought-tolerant, and has low requirements for soil, so it can be cultivated geographically or on hillsides. It has wide adaptability to light and can be intercropped with higher crops. The aboveground part of day lily is not cold-resistant, and the underground part is cold-resistant to-10℃. Avoid excessive soil moisture or water accumulation. When the ten-day average temperature is above 5℃, seedlings begin to emerge, and the suitable temperature for leaf growth is 15℃ ~ 20℃. Flowering requires high temperature, and 20℃ ~ 25℃ is more suitable.
