There are a lot of synonymous, common names for this plant. It is often called a bone worm, iron ore, solidago. Gardeners love goldenrod for ease of care, beauty and rapid growth … Let us consider in more detail the description, types and varieties, features of planting and care of goldenrod.

Description

Goldenrod or solidago refers to herbaceous perennials with a raceme-like rhizome. The roots of the plant are quite powerful, strong, deep. On the surface of the soil, a shoot is not too branched, of a simple type. The height of the grass is up to 1 meter, the type of stem is longitudinal, straight . The stem is covered with satin-type bark, the color is purple or emerald. The foliage of the grass has a juicy shade of green, looks like an oval or egg in shape. The edges are sawtooth, with jagged edges. At the bottom, the foliage grows narrower and elongated, somewhat similar to willow leaves.

Flowering begins in late spring and lasts until autumn, the yellow beauty of the inflorescences is very impressive. The flower is formed by bell-type buds, the color is yellow, lemon. In the middle, the shade is close to chestnut.

The aroma of flowers is intense. At the end of flowering, a fruit is formed in the form of a cylindrical achene with longitudinal ribs.

Non-specialists often confuse the plant with ragweed, garden mimosa. However, goldenrod is significantly different from them. Ragweed, for example, looks more like wormwood, the flowers form into an inflorescence like an ear, rather than a bell. The stem has grooves and is bristled with bristles. Goldenrod is considered an aggressive plant, as one plant is capable of dispersing about 100,000 seeds, which are almost completely germinated.

Landing features

Planting goldenrod on the site is not difficult, but time must be taken to assess the soil. It should be quite nutritious, it should be fertilized regularly with organic matter, compost . Goldenrod prefers moist fertile soils. If the soil is poor, you will need top dressing. Improving soil quality will result in abundant and luxurious flowering. The scarcity of the soil is reflected in the beauty and decorativeness of the plant. Compost is best suited for these purposes.

During self-sowing, some of the seeds become non-germinating, some plant varieties do not form seeds at all or they do not have time to ripen. therefore this representative of the flora is rarely bred with seeds . This must be done through seedlings, and can also be purchased ready-made in garden stores.

It is planted in open ground both in the spring and in the fall. Healthy, strong shoots with abundant foliage are suitable for these purposes. Do not plant plants with spots or insects.

Choosing a site is not difficult, both sunny and shaded areas are suitable. The optimal soil is wet and heavy, so you should not loosen the soil with sand and other methods . The gaps between the bushes should be about 40 cm, more, but not less. For one square meter, the amount is calculated depending on the variety - from 2 to 5 bushes on average.

Subtleties of care

Goldenrod will not particularly burden with its presence on the site, it is unpretentious and very resilient … This is a great plant for not very active gardeners who cannot devote a lot of time to grooming. If it grows in the sun or in partial shade, there will be no problems with it. In deep shade, the plant feels normal, but blooms later. This flower it is recommended to regularly and correctly water, giving preference to one abundant watering, rather than a few meager ones.

Additional moisture is required only in case of dry and hot summers. If the flower does not have enough moisture, it can get sick, flowering will become scarce. The plant is sensitive to alkali, so tap water can be harsh for it. Rainwater is ideal.

Poor soils need fertilizer - mullein, compost, mixed organic matter, for example, mineral dressings with horny flour, while the composition should not contain lime. Top dressing is carried out once a month until the plant stops blooming. An excess of minerals leads to active growth of stems, flowering decreases. After the inflorescence has withered, it must be removed if there is no purpose to provoke self-seeding. Higher grades require a garter. The frost resistance of the culture is high, therefore, the plant is not covered for the winter period.

Competent care helps prevent insect attacks and various plant diseases . In a weakened state, goldenrod is susceptible to powdery mildew and aster rust. A particularly dangerous environment for the development of dew is hot weather. Weak shoots must be removed immediately. If there was an excess of nitrogen in the top dressing, the risks of powdery mildew increase, but ash can reduce them to a minimum. In the case of any fungal diseases, fungicide preparations are used. If the plant is attacked by slugs or caterpillars, it is necessary to rob them and treat them with insecticidal agents.

Reproduction methods

This representative of the flora reproduces in different ways: by seed, by dividing the bush, by cuttings. These processes do not create difficulties, therefore, they are available even to novice gardeners. Rooting usually occurs without problems.

Seeds

This method significantly reduces germination; fresh specimens must be used. Seeds that have been in place for over a year will not work . Landing in open ground is carried out in any spring month - it depends on the climate of the region. After disembarkation, the area is covered with polyethylene, cloth. Before planting, the soil is dug up, loosened, equal to a rake.

Seed material is laid out in a ditch at a decent distance. The sowing is covered with earth from the grooves, equal to the rake. After disembarkation, watering is carried out, it should not be allowed to dry out. After germination, after about 2-3 weeks, the seedlings are thinned out. There may be no flowering in the first year. To increase the percentage of germination, you can grow seedlings at home in containers with high-quality irrigation.

Important! The seed method is the most unclaimed among gardeners.

By dividing

This method is very simple and is therefore the most commonly used method. The bush is dug out, parts are cut off with a knife, you can gently tear it off with your hands. Selected seedlings are planted in selected zones, 40 cm apart. In the second year, the plant is already capable of producing root-type shoots, but it is better to postpone the division until the goldenrod is 4 years old . The event takes place in spring or autumn.

Cuttings

Cuttings are separated from the plant of the uterine type, from the upper zone of the plant, inflorescences on them are not welcome. The optimum length of the process is not less than 10, but also not more than 15 cm . The cut must be held in a solution that stimulates growth, after which rooting is carried out in any container filled with soil. The substrate can be made independently by mixing equal parts of sand and loose soil without fertilizers, you can buy it ready-made in the store. Cover the tray with glass on top, you can use cans or polyethylene and put it out in a sunny place.

After 2-3 weeks, the roots appear, the seedlings are ready for transplanting to a pre-selected permanent place.
