Phlegmatic phloxes and astilbae - how to grow

For many years I have been trying to grow phlox and astilbe on my participation. I bought all sorts of varieties, I wore a bunch of money, but they don’t live with me. Tell me what is my mistake. I put it in the ground in mid-May, I bring in humus. Accepted and even grow, but in the heat the leaves begin to dry. I have a panic: I start spraying twice as much for everyone in turn - from diseases and pests. But it is not possible to save the plants. Friends say: "Not your plants, do not plant." And I do not want to believe it. I would like to have at least one bush.

To successfully grow a plant in your garden, you need to create conditions suitable for those in which it grows in nature. Despite the fact that breeders try to improve not only decorativeness but also other characteristics to create hybrids and varieties in order to expand the climatic zone of the species application, the plants genetically have the basic requirements for successful growth, corresponding to their origin.

Now it's about phloxes and stilbas. Both those and others are winter-hardy plants, i.e. Our harsh winters - not a hindrance to their successful cultivation. In our hot climate both phlox and astilbe are oppressed by air drought. To successfully grow these plants, you need to think about how to create a more humid microclimate.

Astilbe and paniculate phlox are distinguished by high decorative and therefore desired in the garden. But to see them blossoming, it is necessary to study the peculiarities of growing these plants, and try to carefully apply them.

ASTILBE - perennial herbaceous plant of the Saxifrage family. Complex, very delicate leaves are collected in a basal rosette, and small flowers in a paniculate inflorescence. Almost all of the many types of astilbe in nature grow in China, Japan, and only two in the Far East. Compare the climate of Japan and the Volgograd region. In Japan, it is soft, moist, with a minimum temperature difference in different seasons of the year. Almost everywhere in Volgograd and the region it is severe, with a strong temperature difference in winter, with dry, hot weather in summer, i.e. sharply continental climate. Here is the answer to the question why astilbe is uncomfortable with us.

Agrotechnics of growing Astilbe

The advantage of astilba is the ability to develop well in the penumbra, but not in the penumbra, when half the sun, half a day shadow, and in the constant lacy shade of trees. If the shading is too strong, it does not bloom well. Another excellent quality of Astilba is high winter hardiness. In addition, astilba is practically not affected by diseases and pests, so the increased spraying with fungicides and insecticides, which our reader resorts to, is pointless.

There are several ways to create suitable conditions for the safe growth of astilbe.

For the landing of Astilbe, we do not need to wait for mid-May (at this time our air temperature can be quite high), it is better to do this in mid-April.
When choosing a site for planting, preference should be given to areas with diffuse lighting. It is better to plant astilba in a light shade of trees or from the north side of the house.
Loamy and peat soils are suitable for cultivation, which are sufficiently moistened throughout the growing season. But avoid places where water stagnates during the winter thaws. In such areas, the probability of plant escapes increases.
Particularly favorable for planting astilba places with high humidity: near water bodies, near fountains and swimming pools. But if there is no pond? Increase the soil moisture for astilbe can be by placing them among the host, which have similar requirements. The host leaves cover the soil well, keeping humidity, guarding against overheating on hot days. Suitable and other plants with large leaves with similar growth conditions. The denser the planting, the better the plants feel.
When planting the rhizome is placed at such a depth that above the buds of renewal there was a layer of soil 4-5 cm, i.e. strongly deepen. After planting, the soil around the plant is mulched with a layer of peat or humus to preserve moisture. The plant is watered regularly for two weeks, until it takes root. In dry, hot weather, watered regularly. At evening watering, astilba and hosts are sprayed on top, on leaves.
In many astilbe with a vertical rhizome, its upper part eventually protrudes from the soil and bare, towering above the ground in the form of a hummock. To avoid this, two steps must be taken.

Astilbe - care

1. Every three years, dig up the plant, if necessary, divide and plant with deepening.

2. Regularly in the spring and autumn mulch peat soil around the plant. The thickness of the mulching layer depends on how much the rhizome of Astilba has risen above the ground. If this is not done, the buds of renewal will fall into unfavorable conditions, the blossom of astilba will weaken, the leaves will begin to dry.

The simplest and most reliable way of vegetative propagation of astilbe is to divide the bush. The best breeding time is early spring. Large adult specimens are dug up, their solid rhizome is cut with a sharp knife into several parts so that at least three kidneys are on each part. At the same time, it is recommended to remove the lower parts of the rhizome, since they should still die out, because the growth occurs due to the upper part of the rhizome. Immediately after dividing, parts of the bush are planted. In spring, astilbe vegetation begins relatively late, when the daytime air temperature does not drop below 10 degrees. Therefore, if spring is late and cold, astilba begins to grow late.

Blossoms an astilbe 1-3 weeks. After flowering, to preserve the decorative effect of planting, inflorescences are cut at the soil level. After flowering, new foxes begin to grow. Pruning of the entire aboveground part is carried out late in the autumn. An additional shelter for the winter does not require astilba: a good layer of mulch can cope with the role of shelter.

Astilba responds well to fertilizing in spring and summer (after flowering) with organic and complex mineral fertilizers.

Varieties of Astilbe

At present, about two hundred varieties have been created. Not everyone is equally well with us. There are varieties quite stable in our climate: abundantly bloom, do not lose leaves in the heat, grow well. I list the varieties tested by the growers and time: white - Deutschland, Avalanche, Diamond, Snowdrift, White Wing, Weiss Gloria, Bruteschleer, Professor Van der Vilen, Davins Snow; Reds - Final and Glut, Etna, Spinel, Montgomery, Red Santinel; with differently colored flowers - Amethyst, Bremen, Gloria, Finale, Lolipop, Catley, Snowdrift, Superba, Vigins; with drooping inflorescences - Strzu-senfederer, Avalanche, Bruteschleer, Professor Van der Vilen, Moerheim, Flamingo, Pink Lightning.

Another recommendation: it is better to purchase large varieties with a height of at least 40-50 cm. The logic of this choice is as follows: a large plant will better cope with dryness and heat in the summer, and even among the host it will not “get lost”. Miniature astilles must be planted in plain sight, from the edge, where it is difficult to cover them with something to protect them from the summer heat.

Some varieties of foliage are large, sparse, and others are very dense. Choose varieties with abundant dense foliage.

If the above recommendations are followed, the astilbae grow quite satisfactorily in our gardens. Create a stilbam as comfortable as possible, and they will please you with their unusual flowering, elegant openwork foliage. Astilbs, like no other plants, illuminate the dark corners of the garden with multicolored salutes of unique fluffy inflorescences.

Growing of paniculate phlox

FLOX METHELIC there is no need to describe in detail: everyone loves it. And for the beautiful lush flowering, and for the wonderful fragrance. Phlox is becoming more and more desirable because in recent years you can buy plants of sophisticated colors, adding them to the familiar white and pink phlox. But the phlegm panicle is unusually lavishly blooming in the more northern latitudes, and in our climate during its cultivation the growers face problems. To flox fluffy really happy, showing us all their beauty, you need to know some tricks.

Do not plant phlox on the scorching sun, they feel fine in the penumbra.

Phlox refers to plants with high nutrient intake. Loves the fat soil (preferably loam), in the sandy soil it is necessary to add compost. When preparing the soil, make humus, compost, peat, add phosphorus-potassium fertilizers, wood ash. Alkaline soils for phlox are of little use: with excess of lime, the leaves turn yellow.

Immediately after the snow falls, phloxes are fed with nitrogen fertilizers, which you can simply sprinkle around the bushes. But in summer it is better to make complex fertilizers dissolved.

The soil must be sufficiently moist. With a lack of moisture, plants are low, and inflorescences are short and few-flowered. When the soil overheats, the young roots first of all suffer, causing drying of the lower leaves.
In May, the tops of individual stems are pricked (for example, half of the stems of the bush), the bloom will move somewhat, but it will be more prolonged and lush.
The basis of summer care is mulching and regular watering.
They fly phlox in April-early May or in September-October. Bushes should be divided every four years.

Phlox melancholy is cold-resistant enough, but in frosty winters, freezing of shrubs is possible. Plant accidents are observed after winters with frequent thaws. First of all, the kidneys of renewal are frozen out, and the roots remain alive. There is an effective method for reviving shrubs. The place where phloxes grew is loosened to a depth of 3-4 cm, mulched with peat and watered regularly. On the surviving roots are laid subordinate growth buds, of which in the first year will develop short, and next year-normal flowering shoots.

The shoots of the astilba planted on the shore of the reservoir were covered with a gray bloom. Later, several young bushes withered, although in the early summer often rains. What is it? And is it possible to save plants?

  This fungal disease is fusariosis (root rot). Most often manifested in the form of a whitish-gray plaque (traces of sporulation of the fungus) in wet weather. It also affects peonies, chrysanthemums, especially in low-lying areas with clayey heavy soils and stagnant water. Stronger damage to weaker plants, with low immunity.
  Control measures
  At the first symptoms, treat plants and soil around the 0,2% "Fundazol". In case of severe damage, the bushes are recommended to be excavated and burned.
  Henceforth, use only healthy planting material (seeds, seedlings, delenki) from a reliable producer.
  Observe the rules of landing. Astilba prefers semi-shaded areas with well-drained fertile moistened soils (with the addition of humus and handfuls of ashes to the removed soil 1 / 3 or 1 / 4). The root collar when planting chunks deepen a little lower (at 2-3 cm) ground level.
  
  In the care it is necessary to loosen the soil around the plants, mulch, if necessary, water and feed first complex, after flowering - potassium phosphate fertilizer (according to the instructions).
  Every 3-4 year, the bushes are divided, to ground out the rhizome in spring, pour the soil.
