Vegetative Growth (Late Spring to Early Summer)
6-8 weeksFern-like foliage fully develops, creating an attractive mound; plant reaches 24-36 inches tall
Water regularly; ensure consistent moisture; apply balanced fertilizer once in early summer; deadhead spent flowers if desired for neatness
Flowering (Mid to Late Summer)
4-6 weeksDense, feathery plumes of rose-pink flowers emerge on tall, sturdy stems above the foliage; flowers are very showy
Maintain consistent moisture as flowering drains plant energy; stake tall stems if needed in windy locations; deadhead spent flowers to encourage extended bloom
Seed Development (Late Summer to Fall)
4-6 weeksFlowers fade to tan/brown; seed heads form and may persist into winter if not removed
Cut back spent foliage after first frost or leave standing for winter interest and wildlife shelter; reduce watering as temperatures drop

Harvest Tips
Astilbes are ornamental flowers; harvest fresh plumes by cutting stems at the base when flowers are fully open. Remove spent flower heads to encourage a tidier appearance and redirect energy to root development. Leave some flowering stems standing into fall for seed head interest and wildlife shelter. Cut back all foliage after first frost or in early spring before new growth emerges.
