1. Temperature

Wulan is a typical subtropical fruit tree that likes high temperatures and is afraid of frost. The best annual average temperature is around 22°C. The average temperature in January can be around 13°C, and the temperature cannot be below -2.5°C. 2. Moisture

The root system of Wu Lai likes to be moist and avoid waterlogging. Waterlogging can easily cause root rot and poor growth. Appropriate moisture should be given during the breeding period to facilitate good plant development. It is better for the soil used for breeding to be slightly moist. 3. Soil

Wulan has less stringent soil requirements and can be planted in red soil, yellow soil, riverbank alluvial soil, sandy loam, gravel soil and light clay loam. However, it is best to choose slightly acidic soil with a deep, loose, moist, well-drained soil layer and a pH value of 4.5 to 6 for planting. 4. Lighting

Ophiopogon japonicus is a light-loving fruit tree and can tolerate moderate shade, so during plant cultivation, extra light time should be given. At the same time, you should pay attention to proper shading in hot summer to avoid burning the leaves and promote plant growth. Only then can the leaves grow green and bright, and the flowers bloom more beautifully.
