When & Where to Plant Astilbe
Light: Astible grows best in part shade. It can thrive in full sun, but will need shade in the afternoon in hot summer climates. In full shade, flowering will be reduced.
Soil: Astilbe thrives in moist, well-drained soil that has a slightly acidic pH (6.0). Add organic matter to keep the soil from drying out. If soils dry out the foliage may curl and scorch during the hot summer.
Spacing: Space astilbe plants 18 to 24 inches apart. The clumps will spread quickly when grown in the best conditions and will need dividing every 3 to 4 years to keep them in bounds.
Planting: Plant astilbe in spring or fall. Avoid summer planting due to astilbes aversion to drying out. Astilbe can be started from seed, but it may be hard to germinate and will take a few years to get a substantial plant. Since astilbe spreads easily, a better way to get new transplants is to divide mature plants.
