Firstly, its delicate carved leaves do not like direct sunlight, secondly, the root system does not tolerate overheating, and thirdly, the plant cannot tolerate dry soil.
Therefore, it is better to plant astilbe in the shade and mulch the ground around it.
What does astilbe like: sun or shade
You need to choose a suitable location and soil, taking into account the flowering time.
These perennials grow best in partial shade (especially those that bloom in July).
Early and late bloomers tolerate both shade and sun.
Pink and white astilbe are brighter in the light, but fade faster.
What to put in the hole when planting astilbe
When planting astilbe in the spring, dig a small hole (20-30 cm deep), pour in 30 g of granular complex fertilizer, 1/2 cup of ash, add humus, mix thoroughly and water generously.
Watering astilbe correctly
If astilbe grows in the shade, then it needs to be watered as the soil dries out, usually even in dry and hot weather this is no more than 2 times a week.
If the climate is hot and dry, and you planted the plant in an area where it is sunny for at least a few hours a day, watering is necessary every day.
A common reason why astilbe leaves dry is a simple lack of moisture and too hot and dry air.
In the southern regions, the choice of planting site must be approached especially carefully.
Astilbe does not tolerate heat and bright sun.
In a sunny place, plants need to be watered 2 times a day.
