The cultivation method and precautions of Polygonatum sibiricum

1. Maintenance methods

1. Soil: Sandy loam or loose soil with good water retention is suitable for growing Polygonatum. Because Polygonatum sibiricum likes shade and moist soil, some farmyard manure should be applied before planting, and then the land should be tilled. This will help promote the absorption of nutrients by Polygonatum sibiricum after planting.

2. Water: Always keep the soil moist because it is afraid of drought. It is also necessary to drain the water on rainy days to avoid excessive water accumulation which may cause root rot.

3. Nutrients: Fertilizers generally use chicken, duck, pig manure and human feces at home, and some farmyard manure can also be applied appropriately. During the growing period, you need to weed and till the soil regularly, but only shallowly.

4. Sunlight: A cool and shaded place should be chosen for cultivation. It likes moisture and avoids places with strong sunlight, as strong sunlight will sunburn its branches and leaves.

1. Leaf spot disease: Leaf spot disease often occurs during its growth period. At this time, you only need to use wettable powder of mancozeb diluted with water for spraying and prevention.

2. Root rot: The reason for root rot is the presence of water in the soil. If it is not drained in time, it will cause root rot of Polygonatum, so it is necessary to drain in time.
