It is not always easy to find plants that thrive in the shade. Especially plants that also impress with pretty flowers. However, one can be found in almost every garden and is also very popular there: the Astilbe. It is a plant from East Asia, which comes with multiple leaf leaves and whose inflorescences are somewhat reminiscent of feathers. It looks really extraordinary. Mainly because the Astilbe not only blooms in white, but also in red, pink and violet.
But it is not only because of its appearance that the Astilbe is often planted in the garden. But also due to the fact that it thrives where other plants are simply too dark, cold and damp. So if you have a lot of shady spots in the garden, the Astilbe is just the thing for you. However, you have to do a lot to ensure that the plant thrives splendidly.
When do Astilben bloom?
Astilbe are perennial plants. The first bloom in June / July. Others only in August and September. If you buy Astilben, then always pay attention to the flowering period. Because if you choose the varieties skillfully, you can enjoy a sea of flowers all summer long. Astilbe are best used in small groups. Individually, they go under visually next to bigger neighbors.
Where do Astilbe thrive best?
As you have already learned, Astilben like it dark and moist. So the best place for the plants is a shady place. But it can also be partially shaded. In addition, the soil at the location should always be nice and humid, because the Astilbees don't like dryness at all. If the soil in your garden contains sand or limestone, you can still plant Astilben. Finally, there is a trick on how to perfectly prepare the soil for the Astilbe:
Place a container, such as a large flowerpot with a water drain hole, in the ground. Fill in a layer of gravel as drainage at the bottom. Then you have to fill in plant soil for rhododendrons or compost and use the plants. Then always water vigorously and the beautiful flowers will thrive even in sandy or calcareous soils.
How to plant Astilben properly
You can plant Astilben in spring or in autumn. It is only important that you plant them deep enough, because over time the root balls will push up. You must also ensure that the planting distance is large enough. A distance of approx. 20 centimeters is recommended for dwarf varieties and a distance of approx. 40 cm for larger plants.
Caring for Astilben properly
As a rule, you do not have to water astilbe. However, if there are dry periods, you even have to reach for the watering can. So check the condition of the floor regularly. If it is very dry, water the Astilbe abundantly. Incidentally, this does not only apply to freshly planted Astilben. Older plants also need plenty of water during longer periods of drought. By the way, rainwater is recommended for watering, since Astilbe are sensitive to lime.
A little hint:
To prevent the soil from drying out so quickly, simply spread some mulch around the Astilben. This also reduces weed growth. Reading tip: Apply bark mulch - how it's done.
We recommend fertilizing the Astilben twice a year. Once in spring (early April) and once in autumn (after the growing season). It is always advisable to use compost because it provides the plants with the best possible nutrients. The compost also keeps the soil nice and moist. If you don't want to work with compost, you can also apply slow release fertilizers.
As a rule, astilbe need not be cut. Not even when the plants have faded. On the contrary: let the faded seed heads of the perennials stand still. They turn bronze to brownish in autumn and look really beautiful. In spring you can then cut them off to make room for the new flowers.
Astilbe are hardy. So you do not have to take any special measures in the cold season. Nevertheless, it is advisable to cover the plants with some brushwood to protect the roots from too strong a winter.
If you have planted the Astilbe in a bucket, you can simply bring the bucket into the house and put it in a frost-free room. You can also leave it in the garden. Then, however, it is advisable to wrap the tub with a bit of bubble wrap and cover the plant with brushwood.
