Polygonatum arisanense prefers consistently moist soil. Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot.

Reduce watering frequency during winter dormancy, allowing the soil to dry out slightly more between waterings.

Remove any dead, damaged, or yellowing foliage at any time of year. After the plant has finished flowering and setting seed, cut back the spent flower stalks.

In late autumn or early winter, cut the entire plant back to the ground to maintain tidiness and prepare for new growth.

Polygonatum arisanense can be propagated by division of rhizomes in early spring before new growth emerges. Carefully separate healthy sections of the rhizome, ensuring each piece has at least one bud.

Replant immediately in well-draining soil. Seed propagation is also possible but slower.

Repot Polygonatum arisanense every 2-3 years or when the plant becomes root-bound. Spring is the ideal time for repotting, just as new growth begins. Use a well-draining potting mix.

Ensure the rhizomes are planted at the same depth as before. Water thoroughly after repotting.
