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.
