Astilbe chinensis, commonly known as false goat's beard, tall false-buck's-beard or Chinese astilbe, is a plant in the saxifrage family, Saxifragaceae. It is commonly grown in shade gardens.
They love rich, moist soil. An annual spring dose of 5-10-5 organic fertilizer helps them produce their beautiful blooms year after year from spring through summer.
A soil composed of peat moss, loam, or sand, or any soil mixture with good drainage can be used. The soil should not be overly fertile.
Deadheading astilbe won't encourage new flowers, so you should leave them in place through the fall. Eventually, the flowers will dry on the stalks but should stay in place. When winterizing astilbe plants, you can cut all the foliage off, leaving just a 3-inch (7.5 cm) stem above ground.

After the first hard frost, put down about two inches (5 cm) of mulch around the stem. This will help regulate the temperature of the soil and keep the roots moist through the winter.
