Water: Originating from high-altitude Himalayas, sikkim rhubarb needs weekly hydration and thrives in well-drained soil with consistent moisture. This resilient outdoor plant, common in alpine gardens, stores water in its thick leaves, enabling it to survive temperature fluctuations and unpredictable rainfall.

Fertilize: For sikkim rhubarb, use balanced fertilizer monthly in spring and summer, and bi-monthly during dormancy. Apply at half strength to prevent over-fertilization. Adjust based on the plant's response to nutrients and seasonal changes, as insufficient nutrients can affect vigor, while excess may harm roots.

Pruning: Sikkim rhubarb features tall, translucent bracts and thrives in high-altitude areas. Prune in early to late spring by removing dead stems and cutting back post-bloom stalks. This practice encourages healthy growth, minimizes disease risk, and enhances the plant's structure and ecological value.

Propagation: Sikkim rhubarb is a perennial herb with distinctive yellow-bracted inflorescences. To propagate, sow fully ripened seeds in well-draining soil mixed with sand or perlite. Germination thrives in moderate moisture and cool temperatures, while avoiding waterlogging is crucial for seedling health.
