Cultivation methods and precautions of Yunnan Polygonatum

1. Maintenance methods

1. Soil: It has high requirements for soil and is suitable for growing in fertile soil. Soil with deep soil layer is also suitable for its growth. When preparing it, just use garden soil + leaf mold.

2. Light: Yunnan Polygonatum likes shade and also needs a certain amount of light during its growth period. The planting of Yunnan Polygonatum is generally chosen in a semi-shaded place or in a place with shade next to the planting site to prevent direct sunlight. However, it is also necessary to ensure that there is some diffuse light, which will be of great benefit to its growth.

3. Water: Yunnan Polygonatum needs a lot of water to grow, but it does not need a large amount of water each time, otherwise it will easily get sick. During maintenance, watering is required regularly to keep the soil moist. The water requirements of Yunnan Polygonatum are different in different growth cycles. You can water it more during the growing season, but pay attention to water control in winter.

4. Temperature: Yunnan Polygonatum grows best in an annual temperature of 15-25℃ and is not suitable for growing in a hot environment.

2. Breeding techniques

1. Seed storage: Its seeds mature around August. When they mature, you need to collect them and pick out the fuller ones for sand storage. The sand storage method is to mix seeds and sand in a ratio of 1:3 and place them in a shady pit. Then just spray water at the right time to keep the sand moist.

2. Timely pruning: If poorly growing leaves appear on the plant, they should be cut off in time to prevent them from affecting the growth of the entire plant.

3. Problem diagnosis and treatment

1. Disease: Its main disease is leaf spot, which often occurs in summer and autumn. The diseased leaves will turn white in the middle and have large brown spots on the outside. In severe cases, it will affect the photosynthesis of the leaves and cause the death of the entire plant. In the early stage of discovery, it is necessary to spray 500 times diluted 65% Zineb for treatment.

2. Pests: Its main pest is the bark beetle, which mainly harms the roots and rhizomes of the plant. Adult insects can be killed by luring them with light or spraying them with 800 times diluted 90% crystal dichlorvos.

IV. Other issues

1. Can it be grown indoors: It can be grown indoors. Try not to expose it to direct sunlight during normal care. A little scattered light will be fine. Also keep the air circulating in the maintenance environment.

2. Harvesting time: If cultivated in a warm climate, it can be harvested after 2-3 years of management. The best time to harvest is in spring and autumn, as the products harvested during these two times will be of better quality.
