The success of Astilbe 'Diamant' begins with its location: sun to partial shade, in suitable soil (kept moist, clayey). For Astilbe 'Diamant', regularly check the soil around the root ball: it must remain moist.

To maintain the appeal of Astilbe 'Diamant' after flowering, monitor watering during hot weather and remove old stems when the clump regrows in spring. Drying out of the root ball shortens astilbe flowering and can cause leaf edges to turn brown. For plant pairings, consider perennial geraniums, daylilies, and bellflowers in varieties with similar needs. The flowering period (July-August) and the spread of 50 cm will serve as guides for arranging other plants around this one.
