When is the best time to plant Polygonatum sibiricum?

Most of our friends in rural areas are engaged in breeding or planting. The planting industry includes many types, the most common ones are vegetables, fruits or grain crops. However, in recent years, some friends have also taken advantage of the local unique geographical conditions to choose medicinal material planting industry, and Polygonatum sibiricum is a Chinese medicinal plant chosen by many grower friends. Let’s learn together when is the best time to plant Polygonatum sibiricum?

When is the best time to plant Polygonatum sibiricum?

The planting time of Polygonatum sibiricum should be chosen when the ground temperature begins to rise, preferably in spring and autumn. Spring is the best choice for sowing Polygonatum sibiricum, especially in the southern regions. With the arrival of the Beginning of Spring, the ground temperature gradually warms up and sowing can begin. In the northern regions, after the spring equinox, the climate becomes more stable, which is also a good time to sow Polygonatum. It should be noted that different altitudes and climatic conditions, as well as differences in Polygonatum varieties, may affect the optimal sowing time.

In addition to sowing in natural environments, Polygonatum sibiricum seedlings can also be grown in greenhouses. By taking advantage of the greenhouse, the temperature and humidity can be effectively controlled, thus achieving sowing throughout the year without seasonal restrictions. This method can provide a more stable environment for the growth of Polygonatum sibiricum, helping to improve the success rate and yield of planting.

Polygonatum sibiricum planting method and management

1. Soil selection and treatment

Polygonatum likes to grow in moist, loose, fertile, hydrophobic and well-drained soil. Choose soil rich in humus, organic fertilizer and high in phosphorus fertilizer to ensure the growth and development of Polygonatum.

2. Seed germination

The seeds of Polygonatum sibiricum are small and have a hardened surface, so they need to be germinated before planting. Soak the Polygonatum sibiricum seeds in water for 24 hours, take them out and hang them in a wet black plastic bag, waiting for them to germinate.

3. Planting seeds

Before sowing, you need to spray an appropriate amount of water in the plastic bag, then sprinkle the seeds evenly on the soil, and pat them to make them fit the soil. The sowing area is then covered or sprayed with water to ensure that the Polygonatum sibiricum seeds can adapt to the environment and grow quickly under suitable conditions.

4. Rhizome propagation

In late autumn or early spring around late March, dig up underground rhizomes, select the tender part at the tip, cut into several sections, each with 3-4 nodes, dry the wounds slightly, and plant them in the prepared ridges with a row spacing of 50-50 cm, a plant spacing of 50-50 cm, and a depth of 12 cm. Cover with 5-7 cm of soil, and press down slightly to keep the soil moist.

5. Field management

After planting Polygonatum, field management needs to be done well. Frequent weeding is required in the early growth stages to prevent weeds from competing for nutrients. Be careful not to damage the roots when weeding. Combine topdressing with tillage and weeding every year to prepare the soil and apply fertilizer to cover the soil. During the growth period of Polygonatum, you need to pay attention to water. It likes moisture and is afraid of dryness. The field should always be kept moist. Water it in time when there is a shortage of water. During the rainy season, pay attention to clearing ditches and draining water to prevent a large amount of water from accumulating in the soil and causing root rot.

6. Disease prevention and control

Common diseases of Polygonatum include leaf spot disease and black spot disease. After becoming infected, spots will appear on the plants, affecting their normal growth. For leaf spot disease, you can use a diluted solution of Zineb for spraying treatment. After contracting black spot disease, you should spray Bordeaux liquid once a week to allow the plant to resume healthy growth.

The above is an introduction to the best planting time and management points for Polygonatum sibiricum. When planting Polygonatum sibiricum , you can first choose the appropriate time according to the local environmental and climatic conditions.
