Astilba is a perennial plant from the family of Sturgeon.
Its homeland is considered Japan and East Asia.

This culture has gained popularity due to its
unpretentiousness, frost resistance (rhizomes withstand frosts to
-35-37 ° C) and decoration (she is beautiful before, during and after
flowering).

In addition to flower beds and alpine slides, it can also be grown in
flowerpots that will be a great decoration for the veranda or
terraces.

Types and grades of astilbe

Breeders bred various varieties of astilbe (from dwarf
to tall, with different colors), which
divided into several types. Among them the most
popular:

• Astilba Arends – mainly represented by tall
varieties (0.6-1.1 m in height). Famous varieties: Pomegranate, Glut
Bergkristall, Amethyst, Brautschleier, Gloria, Weiss Pearl, Elizabeth,
Erica Bressinghem Beauty, Hyacinth;

• Chinese Astilba – Curtain Creatin
therefore, it can be used as a groundcover. Grades:
Troll, Serenada, Purpurkerze, Intermezzo;

• Astilba monolithic hybrid – unstable in the heat and
drought view. Drooping inflorescences give the plant an airy look.
Popular varieties: Praecox Alba, Darwin’s Snow, Sprite, Bronze
Elegans;

• Japanese astilbe – a feature of this species is previously
bloom (end of June) and the average growth of bushes (0.5-0.7 m). Outline
varieties: Montgomery, Bremen, Ellie, Koblenz;

• Astilba Thunberg – the most moisture-loving look. Reacts poorly to
frequent division of rhizomes. Such varieties are widespread

Astilba: landing

When planting astilba, it is important to choose the correct location.
Although this plant is unpretentious, it will still be more comfortable
feel in partial shade and shady areas.

Plant astilbu better in semi-shady places

The close occurrence of groundwater at the site will “delight” astilba –
in nature, it grows along the banks of reservoirs. Therefore, if your
land tenure is a natural or artificial pond or stream,
then they will come in handy. Soil astilba prefers
fertile loam with pH = 5.5-6.5. If on the selected site
acidity is increased, then to reduce it you need to make wood
ash or dolomite flour.

For planting choose high-quality planting material. Rhizomes
Astilbe must be healthy, elastic, dead and without
dry areas.

The parameters of the landing pit should be done taking into account the size

mineral fertilizers (25-30g), approximately one handful of ash and
bone meal. No excessive burial is allowed during landing.
Bush – the growth point should remain above the ground. After
this plant is watered and mulched ground crushed bark,
peat crumb or humus. This will protect the root system from
drying out

Astilba: cultivation

Astilba can be grown from both seeds and
vegetatively.
It should be remembered that perennial
plants grown and seeds often do not lose varietal traits (in
they may be a different color, weaker and shorter flowering).
The use of high quality seed varietal selection will reduce
The percentage of such inconsistencies.

Astilba seeds before sowing is better to expose

The procedure will increase the germination of seeds. For this mid February
the seeds are sown in a bowl with a moistened peat-sand substrate,
cover it with a film, put it in a fridge or on an unheated one

grown at room temperature, periodically carefully
pouring out a syringe without a needle. After появления 2-3 настоящих листиков,
seedlings dive in separate pots. Plants planted in the garden
after passing the threat of night frosts.

The most reliable and easiest way to breed astilbe –
division of the bush.
Maternal plant is dug up, knife
cut the bush into pieces so that each of them does not have
less than 2-3 buds. All sections are powdered with activated powder.

Astilba can also be grown from the kidneys. For this spring, when
the vegetation of the plant began, cut off the shoots with a sharp knife
pieces of rhizomes. After дезинфекции срезов, полученные черенки
planted in a greenhouse in a peat-gravel mixture (3: 1). In the open
soil young plants transplanted in the fall or next
in the spring.

Astilba: care

Caring for astilba is not difficult. Due to the fact that rhizomes have
Astilbs grow up, not down, as they grow, they become bare.
Therefore, it is necessary to add soil every year. As a result
a few years later a mound forms around the bush. It does not look
quite aesthetic, so astilba every 5 years it is better
transplant.

To preserve soil moisture and protect the roots from
overheating the ground under astilba bushes with peat mulch,
crushed bark, expanded clay or landscape rubble. Winter coat
Mulch protects the roots from freezing.

Mulching planting astilbe

Faded stems should be trimmed to preserve the decorative
plant species. In autumn, the entire above-ground part of the bush is completely cut off.
If this has not been done, pruning is done in the spring before
growth of young shoots.

In the spring, when the active growing season begins,
It is advisable to feed astilba with nitrogen fertilizers, and during
potash phosphorus blooms. After подкормок землю под
bushes loosen and mulch.

Astilba is a moisture-loving plant. It does not tolerate drought.
Reinforced watering is needed astilbe during the formation of inflorescences, and
also in hot summer. Double watering (morning and evening) in such
periods needed every day.

Astilbe diseases and pests

Astilbe is disease resistant and is rarely affected by pests.
However, she has enemies.

This plant is sometimes attacked by drooling penny,
gallic and strawberry nematodes.
