Water: Newly-planted astilbe macroflora requires weekly manual watering until its root system is strong. It prefers moist soil to avoid drying leaf margins and scorch, which can threaten its survival. Regularly check moisture levels, particularly during hot summers or in sunny spots.

Fertilize: To encourage flowering in astilbe macroflora, ensure ample phosphorous with a slow-release 5-10-5 or 10-10-10 fertilizer, applied in early spring. Use high nitrogen fertilizer in late summer for bud setting. For potted astilbe macroflora, apply soluble fertilizer biweekly, and take care to avoid leaf contact.

Pruning: Astilbe macroflora features lush, plume-like flowers and benefits from pruning. In early spring, cut back old foliage and remove spent flower stalks to promote blooms and improve appearance. Pruning also enhances airflow, reduces disease risks, and invigorates growth. Use clean, sharp tools for optimal results.

Propagation: Astilbe macroflora grows slowly, needing division every 4-5 years. In early spring or late fall, divide the root ball into smaller pieces, ensuring each has an eye. Plant immediately in spring or store rhizomes indoors in fall for spring planting.
