The cultivation methods and precautions of Polygonatum odoratum

How to cultivate Polygonatum odoratum

Soil requirements

It is best to choose a slightly acidic sandy soil with deep soil layer, good drainage and sunny orientation for growing Polygonatum odoratum. When planting and cultivating, pay attention to replacing the soil. Change the soil about once every year to ensure the nutrients needed for growth.

Selection of stems

When cultivating Polygonatum odoratum, first choose to use underground rhizomes for reproduction. After preparing the rhizomes, be sure to spread the root buds in a cool, sheltered place indoors for maintenance.

Seed germination

Before germinating the seeds of Polygonatum odoratum, you should soak them in cold water for 24 hours, then take them out and drain the water. Then put the seeds into a wooden box for cultivation, and then place them about 5 cm away from wet sand and wait for them to germinate and grow.

Planting and breeding

Planting is generally done from early to late October, and it is best to choose a cloudy or sunny day to plant, which can promote the growth and germination of new seedlings. During this period, pay attention to keeping warm, watering, and ensuring the moisture of the soil. Also provide enough light.

Notes on the cultivation of Polygonatum odoratum

Winter protection

Although Polygonatum odoratum is cold-resistant, the weather is too cold in winter, so you still need to pay attention to cold protection to avoid frostbite and inability to grow.

Fertilization and topdressing

Polygonatum odoratum likes fertile soil, so it is necessary to fertilize it on time and in the right amount to supplement sufficient nutrients to facilitate the growth of the plant.

Not only should we apply fertilizer, but we should also pay attention to top dressing. This is especially true during the seedling period. However, please note that if enough base fertilizer has been applied, there is no need to apply top dressing to avoid burning the roots.

Pay attention to pest control

The main diseases of Polygonatum odoratum include leaf spot, root rot, gray spot, etc. Pay attention to spraying with drugs for prevention and control.

Pests include white grubs. The method of prevention and control is to use 1000~1500 times the concentration of 90% crystal dichlorvos to water the soil around the roots until the pests are killed.
