Spirea "Frobeli": description, planting, care and reproduction

In the sphere of decorative design of land plots, the Japanese spirea "Froebelii" is very popular. Experienced gardeners note that this variety combines an attractive appearance, unpretentious care and practicality. Today, the plant can be found both in private plots and in city parks and squares.

The ornamental shrub is compact and neat in appearance. During flowering, it becomes covered with lush inflorescences of a bright crimson color. A distinctive feature of the variety is the rich purple hue of young foliage when opened. Over time, by the beginning of summer, the color changes to dark green.

The flowering period is mid-June. At this time, all Japanese spireas are covered with corymbose inflorescences. Under favorable weather conditions, flowers will delight with beauty until the middle of the first autumn month. In autumn, the leaves of the bush are painted in a bronze-scarlet hue, which reveals its decorative effect with renewed vigor.

The plant reaches a height of about 120 centimeters. The width of the shrub is similar in size. The shape is spherical. Annual pruning is recommended to maintain an attractive appearance.

If you purchase ready-made plant shoots from special nurseries, it is recommended to opt for shrubs in containers. In this case, there is a greater chance that the flower will take root in a new area.

Examine the seedling carefully. If there are buds on it, it is better to remove them so that the shrub retains its strength and spent them on adaptation.

Let's take a closer look at the landing and leaving procedure.

According to experts, Japanese spiraea is unpretentious and grows remarkably in almost any conditions (lack of sunlight, low soil fertility, etc.). Even if the direct sun hits the shrub for about 4 hours a day, the plant will retain its attractiveness and delight with its lush color. Despite this, it is recommended to choose a lighted area where the shrub will be as comfortable as possible.

Be sure to arrange a drainage layer at the bottom of the planting pit. Use pieces of brick or rubble as material. Some growers place shrubs on embankments and artificial hills.

The depth of the pit should be 40 centimeters. It is recommended to prepare it at least 7-8 days in advance. A few hours before planting, the seedlings are kept in a solution that stimulates root growth. Shrubs with a closed root system are abundantly watered with the same composition, and then planted in open ground.

The drainage layer must be at least 10 centimeters thick. After that, the pit is filled with soil mixture. The prepared soil consists of half of earth, as well as peat and sand (in equal parts). It is very easy to prepare such a composition at home.

It is also necessary to thoroughly moisten the soil. When planting, the shrub must be deepened into the ground so that the root collar of the plant is several centimeters above the top layer of the earth. At the end of the work, the soil near the bushes is carefully tamped and watered from a watering can.

It is recommended to use mineral formulations as a top dressing. At the start of the growing season, experienced gardeners use nitrogen fertilizers. They give excellent results and work safely on the plant. When buds are laid, phosphorus-potassium dressings are applied.

At the end of summer or in the first months of autumn, spraying is carried out if necessary. The leaves are treated with a solution of potassium monophosphate. It will help the flower survive the winter.

Spirea "Frobeli" does not need to be thoroughly moistened, however, in the first year after disembarkation, it requires more careful attention. Watering frequency should be adjusted according to weather conditions.

You should also arrange a layer of mulch around the plant.

This representative of the flora needs such a procedure as annual pruning. This will help maintain the high decorative qualities of the plant. Sanitary pruning is performed even before the foliage bloom, at the time when the shrub begins to wake up after wintering. During the work, gardeners remove loose and thin branches.

Last year's growth is cut to the level of developed buds. Work on adult plants is carried out more radically: the branches are removed 40 centimeters from the soil surface. Forming at 4-5 years of age actively affects the process of plant growth, and also has a beneficial effect on the formation of the peduncle.

Withered flowers should be removed regularly so that the plant does not waste energy on them. This is necessary for the full preparation of the shrub in the winter.

Spirea has excellent frost resistance. Due to this feature, the shrub can be grown within the boundaries of the fourth USDA zone. Froebelii can withstand up to 35 degrees Celsius below zero.

To protect the root system, the plants are filled with a new layer of mulch from dry compost and then covered with geotextiles. The work is carried out at the end of October or at the beginning of the next month.

It is advisable to feed the shrubs. The nutrients will give the flower the strength it needs to survive the cold. If strong winds are raging on the territory of the region, it is necessary to build a special support for young shrubs.

There are several options for propagating the plant. The seed method is not used for the reason that hybrid varieties are not able to preserve the properties of the mother plants, as a result of which the seedlings completely lose their decorative qualities.

Gardeners recommend choosing one of the following options:

• cuttings (green);
• cuttings (winter);
• layering;
• division.

Reproduction by green cuttings is carried out in the summer, when the time of flowering begins. Gardeners choose a strong shoot and cut it into cuttings. Each of them must have at least 4 sheets. The upper cut is made straight, and the lower (under the kidney) - oblique. To reduce evaporation, the leaves on the cuttings are cut in half, and the two leaves are removed from the bottom.

Further, for about 4 hours, the cuttings are kept in a solution that stimulates growth, or in settled water. After the lower media, they are treated with Kornevin powder and planted in vermiculite or wet sand. Deepen the cutting by no more than 3 centimeters.

The cuttings should be transplanted into a separate container at an inclination of about 40 degrees and covered with a thick film. The containers are left in a dark place. Spray the cuttings every day using a fine spray.

This technique is reliable and simple.It allows you to get young plants with little or no effort. Several shoots should be selected from the bottom of the shrub and placed in the furrows near the mother plant. The branches need to be pinned to the ground in several places.

Further, the shoots should be sprinkled with earth, leaving the top on the surface. She is tied to a peg. In the place where the shoot adheres to the ground, the soil should be constantly moistened. It is recommended to arrange a layer of grass or peat mulch. The new plant should be separated from the mother bush in a year, with the onset of next spring.

This is the easiest way to propagate a plant. The roots of the bush should be cleaned of clods of earth and divided into several parts. On each new plant, a few strong and strong shoots should be left, at least 2 or 3. The procedure is carried out using a knife or secateurs. Places of cuts should be treated with coal powder or brilliant green.

Cuttings are cut from September to October. Leaves are removed. The cuttings are left in water for 2-3 hours and then planted in moist soil, deepening by 5-6 centimeters.

The planting site is covered with mulch from fallen leaves. As a rule, rooting occurs in the spring, with the arrival of heat.
