Water: Tuberous-rooted cranesbill thrives in moderate moisture, preferring evenly moist soil, requiring weekly watering. As an herbaceous perennial, it flourishes outdoors, benefiting from natural precipitation. Water needs vary with growth cycles, necessitating consistent moisture during active growth for optimal foliage and flowering.

Fertilize: Tuberous-rooted cranesbill thrives with adequate nutrients, requiring a base fertilizer at sowing and additional fertilization during its rapid growth in spring (1-2 times). Outdoor plants benefit from slow-release fertilizers, while indoor plants should receive balanced liquid fertilizer post-establishment. Phosphate fertilizers enhance and extend flowering.

Pruning: Tuberous-rooted cranesbill has tuberous roots and delicate flowers, benefiting from strategic pruning in early to late spring. Remove old stems and spent flowers to encourage growth and enhance blooms. Thinning dense areas improves air circulation, reducing disease risk and promoting a healthy, tidy appearance.

Propagation: Tuberous-rooted cranesbill is propagated by sowing in well-drained soil with moderate moisture. Seeds should be sown at a depth allowing light for germination. Light, consistent watering and thinning of seedlings promote healthy growth. Careful handling during transplanting protects delicate tubers for future blooms.
