perennial breeding methods

At one point shrub can grow up to five years,after which it is required to rejuvenate. Propagation is perennial as the early spring and late autumn, using this method of vegetative or seed.

Method # 1 - autonomic

This method involves dividing rhizomes 2-3parts, each of which has deflorate stem from dormant buds. When breeding vegetatively Astilbe can be planted at any time. The main thing - to provide in the first days after transplantation sufficient moisture.

Not bad take root shrubs and flowering period, subject to all the same humidity conditions.

vegetative division bush

In vegetative method lignified rhizome dug out of the ground, washed with water and using a shovel or secateurs cut into sections

The rhizome should be divided so that each plot were cut at 2-3 kidney replacement at the base, which later will the young shoots.

The size of the plot is not significant,portion and will be sufficient rhizomes to 5.3 cm long. They are planted at a distance of 30 cm from each other. The next season planted plots are actively in the growth and spread by lush panicles.

Method # 2 - Seed

This method is quite time-consuming, but it allowsbring new growth. Collect seeds to plant in early September, carefully cutting the inflorescence with boxes. Their spread on paper and left in a warm place for two weeks. To get the smallest peas enough to shake the dried panicles. Collected seeds are placed in a bag and leave until the spring.

When growing Astilbe from seed planting sown in February - March in a container filled with a mixture of peat and sand, taken in the ratio 3: 1.

Small pea seeds Astilbe

Seeds have Astilbe are very small and they grow quite slowly, so their pre-stratification is desirable to subject

Seeds are dispersed on the surface of moist soiland cover glass or plastic wrap. At this stage it is important to comply with humidity regime, preventing the soil to dry out. Some growers recommend to use this "snow" from the freezer, which as melting will gradually moisten the soil.

The first shoots appear after 3-4 weeks, butonly towards the end of the season they form a small rosette of leaves. Watering delicate seedlings should be very careful, subtle directing jets of water at the very root.

If the young bushes in the greenhouse are not close to each other, they can not bother until the following spring. bushes grown from seed will please flowering on the third year of planting.

In mid-July, fueling potassium nitrate (2 tablespoons per 10 liters of water.) And last fertilizer after the blooming - superphosphate, distributing it to 20 grams per bush.
  • Provide timely watering. Moisture-loving plants can not tolerate long-term drought. On hot summer days, it should be watered two times a day. Especially in the strong culture needs watering during the formation of inflorescences. Watering Astilbe better in the early morning and after sunset.

  • Every five years, to rejuvenate the bush. The ability of plant roots quickly build mass requires periodic rejuvenation of the bush. At the end of each season, the bare roots necessarily sprinkle fresh ground. Otherwise, stick out old roots young shoots become bare and dry, which, in turn, adversely affects the quality and duration of flowering.
  • Fighting pests. Nematode and slobbery spittlebug - the main pests of plants. They hit the leaves and rhizomes of the plant, causing its wilting and death. Get rid of the nematodes can only completely destroying the affected instance. With spittlebug little easier. Its larvae can try to destroy mechanically, without damaging the roots and stems, or using garden chemicals: konfidor, Akhtar, malathion.
  • After flowering cut the flower stalks. But some growers, on the contrary, leave the dried flower stalks are not cut, so that they as long as possible adorn the spring garden.
  • Harboring the plant for the winter. In snowy winters the bulk varieties of flowering culture freeze slightly. To prevent it before the onset of cold weather the stems are cut to ground level, the exposed roots of mulch with peat and cover with spruce spruce branches.

In the future, the plant got stronger weed control will perform the self - its powerful roots an excellent job with this task.
