Water: Astilbe grandis thrives in consistently damp soil, reflecting its woodland origins. Watering weekly is essential, especially during the active growing season, to support robust growth and vibrant flowering, although it can tolerate moderate drought conditions.

Fertilize: For optimal growth of astilbe grandis, use balanced fertilizers twice: at the start of spring and mid-summer. Employ a controlled-release formula to avoid stress. Reduce feeding in autumn as astilbe grandis enters dormancy. Apply fertilizer around the base, avoiding foliage, and water well afterward.

Pruning: Optimal pruning for astilbe grandis occurs in early to late spring, removing dead stems and spent flower spikes to encourage growth and prevent overcrowding. This improves air circulation, reduces disease risk, and enhances blooming by pruning before new shoots emerge.

Propagation: Astilbe grandis, from the Saxifragaceae family, is propagated by sowing high-quality seeds in well-draining soil. Plant seeds shallowly for light-driven germination, maintaining moderate moisture. A warm, humid environment aids germination. Once true leaves appear, seedlings can be transplanted into individual pots and later to the garden.
