It is somewhat cold-tolerant, but may be susceptible to freezing in very cold areas. In addition, the room needs to be ventilated frequently in summer to avoid stuffiness.

2. Light: Polygonatum cyrtonema is a shade-loving plant. It does not require much sunlight, but it is afraid of strong light. Therefore, except in winter, it is necessary to provide appropriate shade when encountering strong light in other seasons, otherwise its leaves will be burned and it will also affect its normal flowering.

In addition, after sowing, you need to pay attention to shading and ensuring humidity.

2. Pruning: During the peak growth season, some messy and dense branches and leaves may appear. It is best to thin them out at this time. In addition, it is best to cut off the remaining flowers after flowering, and it is best not to let them remain on the branches.
