Astilbe is a genus of 18 species of rhizomatous flowering plants within the family Saxifragaceae, native to Asia and North America and cultivated by gardeners for their large fern-like foliage and dense flowering.
They are hardy herbaceous perennials widely adapted to shade and water-logged conditions, hence particularly used as pond-side planting.
Numerous hybrid cultivars have been raised.

Plant my false goat's beard
The best planting period is March to April, or between September and November. Plant your astilbe in a semi shade or a shady situation in neutral to acid soil, preferably heavy and moist - for once ...
Prepare the soil by a digging (without necessarily upturning it, with a fork or a grelinette), scratching and raking.
Plant with 0.5 to 1 m between plants according to the species and the variety. Tamp the soil well to avoid air around the roots, then water thoroughly.
Astilbes like humus so a small addition of fibrous compost on the top of the soil will be beneficial.
Planting in pots is possible in a large container placed in the shade, filled with moorland.
Water my false goat's beard
During the first month, water once or twice a week. In case of drought, watch especially your astilbes, they prefer the humidity.
Water adult plants by big inputs even if you do it less often; the plant will develop a better root system if it has to fetch its water in depth. When watering, wait until the water that you pour stops rushing into the ground, and forms a small puddle. Do not wet the foliage, especially in the evening because it will be all the more attractive for molluscs.
Fertilize my false goat's beard
With a respectful approach to soil life, it's always better to fertilize a little in advance with organic material that will decompose; spread out a compost that isn't entirely decomposed, with well decomposed manure at the plant's base, and incorporate over 10 cm with a hoe. This operation is carried out in winter so that earthworms and bacteria have enough time to do their job.
Weed my false goat's beard
Your false goat's beard will widen for several years, so during this interval you will have to weed occasionally to limit the competition. If you have mulched, weeding should not be too frequent.
Propagate my false goat's beard
Astilbes are multiplied by tuft division in March. A spade in the middle, a new hole, and voila ... A few handfuls of compost and a watering can later, you have a new plant.
