Collection of 3 Astilbes

To install, work your soil to a depth of 20 cm (8in), crumbling the soil well and adding a base amendment such as dried blood or horn at the bottom of the planting hole. Position your plant, freed from its pot, covering the top of the root ball with 3 cm (1in) of soil. Fill in the hole and water generously to eliminate air pockets. In dry weather it is necessary to water regularly for a few weeks to facilitate rooting. Astilbes thrive in a marshy area, in a sunny or partially shaded location. They do not tolerate chalky soil that dries out in summer. Spring frosts can damage the flowers and young leaves.
