Correct planting and caring for Ottawa barberry

Landscaping is becoming more popular every year. Now gardeners pay attention not only to the productive and useful qualities of plants, but also to decorativeness. This characteristic is possessed by the Ottawa barberry, which is equally attractive as a specimen plant and in combination plantings.

General characteristics of the Ottawa barberry

The Ottawa barberry species arose as a result of crossing the Thunberg barberry and the common barberry in the city of Ottawa (Canada). In culture since 1889. Natural habitat of ravines, estuaries and forest edges of North America.

In domestic gardening, this type of barberry is known for several varieties.:

  • "Superba" ("Superba"). This is a shrub with a height of 2.5-3m. The leaves have dark red and purple hues with a bluish tint.
  • "Aurikoma" ("Aurikoma"). Forms a compact shrub from 1.8 to 2.2 m. Large leaves when blooming have a dark red hue, closer to autumn they become light red or orange.
  • "Purpurea" ("Purpurea"). A well-branched shrub with a height of 1.5 to 2 m. Leaves at the beginning of the season are purple-red, in autumn they acquire a coral hue.
  • Silver miles. Sprawling shrub with a height of 2 to 2.5 m. The leaves are claret-purple in color with a silvery tint.

All varieties of Ottawa barberry are grown mainly for decorative purposes. The bushes reach full decorative effect 6-8 years after planting.... Shrub flowering begins in mid-May and lasts up to 20 days. The flowers are small, yellow-red.

For fruiting, shrubs require insect pollination. The flowers of the plant are distinguished by high honey productivity (100 kg / 1 ha).

Shrubs begin to bear fruit 5-6 years after planting. Fruiting starts in mid-August and early September, depending on the variety. Average yield per adult bush 10-13 kg of fruits... Intensely red fruits can survive on the bush until December. The life span of shrubs is up to 50 years. With proper care, plant productivity lasts up to 35-40 years.

The advantage of the Ottawa barberry is a high growth rate, the growth of annual shoots reaches up to 35 cm. For the culture, the 4th frost resistance zone (USDA) has been determined. It means that plants can withstand temperatures as low as 35 ° C... Therefore, shrubs can be planted in the southern and middle regions of gardening, and with proper shelter in the Urals.

The disadvantage of the species is the average winter hardiness, which, depending on the variety, has I-II points. This means that annual shoots can completely or partially freeze out of plants.

In general, the Ottawa barberry is an unpretentious plant. It easily adapts to different types of soil, is drought-resistant and shade-tolerant, is rarely affected by pests, and tolerates a gas-polluted urban environment well. Plants quickly recover from mechanical damage, so annual cutting does not affect their productivity.

Planting barberry Ottawa

The best option for the initial planting of barberry in a personal plot is the purchase of a two-three-year-old seedling. It is better to buy planting material in specialized nurseries that breed varietal plants. In addition, in the nursery, there is often an opportunity to visually assess the external characteristics of an adult plant. The seedling quality indicator is a root with a length of at least 20-25 cm without traces of rot and mechanical damage.

For planting the Ottawa barberry, you should choose the most illuminated areas, protected from piercing northern winds. The plant will develop well in partial shade, but the decorative effect of the leaves will be reduced..

Unpretentious to the composition of the soil, barberry is sensitive to excessive moisture. Therefore, the groundwater at the site should be no higher than 2 meters. Otherwise, a solid drainage layer must be laid.

A month before planting, the site must be dug to a depth of 30 cm, weed roots must be removed. In this case, based on 1 m2 contribute:

  • potassium salt 10 g;
  • superphosphate 20 g;
  • manure or compost 10 kg;
  • lime 0.5 kg (with increased acidity).

The distance between the bushes depends on the purpose of planting. During the formation of a dense hedge, 4 seedlings are planted on a site 1 m long, with a more rarefied 2... When the barberry is considered a specimen plant, it is planted 1 to 2 meters away from other crops.

After choosing a landing site, pits 40x40 are formed... The top layer of fertile soil is laid out on the bottom of the pit and fertilizers are applied: manure or compost 30 kg, potash salt 40 g (wood ash 300 g). Fertilizers are evenly mixed with the soil and spilled abundantly with water.

A seedling is placed in the middle of the pit. In this case, it is important to ensure that the root collar does not deepen. Taking into account the shrinkage, it is left 3-4 cm above the ground level.... The roots of the barberry are sprinkled with fertile soil, preventing the formation of voids and unnatural bends. The soil is compacted and watered with 10 liters of warm water. The trunk circle is mulched with humus or peat.

Barberry can be planted in spring before bud break and the soil warms up to + 15 ° C. The plant enters the growing season early, so it will be more difficult for it to take root when planting in spring. Autumn planting 3-4 weeks before the first frost is more favorable for barberry. During this time, the roots of the plant adapt to the soil and undergo the first hardening in natural conditions. This significantly increases their winter hardiness.

The basics of caring for Ottawa barberry

Barberry Ottavsky is not picky about care. Only annual pruning for the formation of a decorative crown can take a significant time for a gardener.

The first top dressing after planting a shrub is done in the spring of next year. To stimulate the growth of shoots, an aqueous solution of urea (30 g / 10 l) is added... Fertilization rate 10 l per 1 m2 trunk circle. Subsequently, nitrogen is fed only once every 4 years.

To lay flower buds and normal ripening of shoots, the plant is fed with organic matter before and after flowering... To do this, 1 kg of well-rotted manure or humus is poured into 3 liters of water, insisted for 3 days and filtered. One liter of infusion is diluted in 3 liters of water and poured under the bush. To strengthen the barberry for winter in the fall, 15 g of superphosphate and 10 g of potassium sulfate are introduced into the trunk circle.

After each feeding and once a week in dry weather, the barberry is watered. The rate for one bush is 5-10 l... After watering, the mulch layer is corrected. Moisture-charging irrigation (20 l) is carried out in dry autumn 2 weeks before frost.

In the first years of life, the Ottawa barberry requires careful shelter for the winter... To do this, the layer of mulch is increased to 10 cm, the branches of the bush are pulled together with a soft rope, and a cap made of burlap or other covering material is covered on top. Additionally, the plant is covered with spruce branches, and in winter they tighten the snow.

Shrub pruning

Barberry Ottawa belongs to ornamental deciduous shrubs, which require annual pruning to maintain their beauty. This is done to stimulate the active growth of young shoots, which are distinguished by leaves of maximum decorativeness.... The second purpose of pruning is sanitary, it is needed to remove unnecessary load from the shrub, prevent the development of diseases and damage by pests.

Sanitary pruning is carried out in autumn... The procedure is carried out when the shrub begins to enter a dormant state, at least 2 weeks before the first frost. Depending on the regional climate, pruning times may start at the end of September and last until the end of November.

It includes the removal:

  • old and withered branches;
  • areas affected by pests or rot;
  • unnaturally intertwining branches;
  • shoots growing inside the crown.

Slices are made only along the annular influx or above the kidney with sharp and disinfected garden shears. Large wounds should be treated with garden varnish. After the procedure, all plant debris, mummified fruits and fallen leaves are disposed of.

Barberry Ottawa perfectly forms the crown in a natural way. This is facilitated by thin branches growing vertically upward at an acute angle. Therefore, with single plantings, you can only do with sanitary pruning.

Plants for hedges will need to be trimmed regularly. In the second year after planting, the shoots of barberry are shortened by 1/3 or 1/2... This will stimulate tillering of the plants. The flowering of barberry occurs on the growths of the last year. Therefore, so that the shoots with flower buds have time to grow, the procedure is carried out immediately after the flowering of the shrub.

In the same way, barberry continues to be cut in subsequent years, until the crowns of neighboring shrubs close. After that, the lateral and upper growths are shortened twice a season. This forms the flat edges of the hedge with a thicker bottom.

The pliability of the Ottawa barberry to a haircut makes it possible to embody many of the fantasies of landscape designers. The bush can be shaped like a ball, triangle and complex multi-tiered shape. At the same time, it is important to know during the formation of the crown 3-4 years, in connection with regular pruning, you will have to forget about the flowering of the shrub.

Diseases and pests

The vegetative mass of Ottawa barberry contains a large amount of phytoncides, which makes it resistant to many pests and diseases. The defeat by pathogenic microorganisms and insects of the Ottawa barberry most often occurs during a mass epidemic in a personal plot or a violation of plant agrotechnology (waterlogging, thickening of the crown).

Pests

The most common Ottawa barberry infect aphids and moths... In autumn, both insects lay eggs capable of wintering, from which larvae and caterpillars appear in the spring. Their activity on young leaves and shoots leads to a loss of decorative effect and productivity of shrubs. Therefore, the fight against them should be started immediately upon detection.

In case of massive lesions of barberry, they are treated with insecticidal preparations:

  • Korbofos;
  • Actellik;
  • Confidor;
  • Bankcol.

The procedure is carried out according to the instructions for each drug.

If the insect population does not exceed the permissible threshold, you can limit yourself to washing the shrub with an ash and soap solution. For this, ash (400 g) is poured with water (5 l) and boiled for 30 minutes.... The broth is filtered, brought to a volume of 10 liters and 50 g of laundry soap is added.

To prevent the appearance of pests during autumn work, shrubs are sprayed with fungicides... To do this, 500 g of urea is diluted in 10 liters of water. Shrubs are sprayed with the solution. It is a versatile remedy that additionally destroys fungal spores.

Diseases

The weak side of the Ottawa barberry - fungal diseases: powdery mildew and rust. Most often, leaves suffer from them, less often shoots and fruits are affected.

Rust can be noticed by the swelling of the leaves and the formation of a powdery dark coating on their surface. With powdery mildew, a white bloom appears on the leaves, on which liquid gradually forms in the form of small drops.

To fight diseases, fungicides are used in the form of finished preparations or active substances for the preparation of a solution:

  • Topaz;
  • Vectra;
  • Fundazol;
  • copper sulfate;
  • colloidal sulfur;
  • Bordeaux mixture.

The drugs are used according to the instructions. Depending on the lesion, it will be necessary to carry out from 4 to 6 treatments until the shrub is cured.... In case of severe lesions, sanitary pruning of problem areas is carried out, followed by waste disposal.

Fungal diseases are the weakest side of the Ottawa barberry. Therefore, even if there are no traces of damage, it is important to carry out the treatment with fungicides every season - in spring and autumn.

Description of the plant

Ottawa barberry is native to the forests of North America. This deciduous shrub belongs to the genus Barberry, the Barberry family. This variety was obtained by crossing the Thunberg barberry and the common barberry in 1889 in Ottawa.

The bush grows to a height of 2 m, there are few soft thorns on the shoots. The growth of shoots per year is 35 cm. The shrub reaches its best appearance at the age of 6-8 years. The leaves are obovate, up to 3.3 cm long, in autumn they acquire a yellow or crimson hue.

The flowering period falls in May and lasts 3 weeks, flowers of a yellowish tint, combined in inflorescences of 10 pieces, emit a strong aroma. Pollination of barberry flowers occurs with the help of insects. Barberry flowers are honey plants and attract many bees and bumblebees with their aroma.

The fruits are oblong, bright red in color, edible, but sour in taste, ripen from mid-August to early September. Fruiting occurs 5-6 years after planting. From one adult bush, you can collect about 10-13 kg of berries. With good care, the barberry bush can bear fruit up to 35-40 years.

Ottawa barberry is famous for its unpretentiousness and endurance to drought, shade, air pollution, undemanding soil quality. It tolerates pruning well and grows quickly.


Classification by type

In addition to the usual shrub with bright red berries, there are less common species in which ripe fruits are colored white or yellow, and not all of them are edible. All varieties are considered hardy and drought tolerant. For medical and culinary purposes, the berries of the common barberry are used.

Common types:

  • Barberry Thunberg. The shrub grows 0.5-1.5 m high. There is a green rim along the edges of the bright coral leaves. On personal and summer cottages, the varieties Golden Ring, Koronita, Rose Glow, Aurea, Harlequin, Maria, Red Chief grow well.
  • Ottawa barberry. A tall species with a spreading crown and yellow flowers, the bushes reach 3-4 m in height. During the growing season, the color of the leaves changes from pink-purple to bright crimson. Varieties bred by breeders: Purple, Auricoma, Silver Miles, Superba.
  • Common barberry. The height of the shrub is no more than 3 m. The crown is compact or spreading. In young plants, the bark is colored yellow-gray or yellow-brown, and with age it acquires a typical gray tint. Most often, the following varieties are planted on the plots: Krupnokolyuchkovy, Atropurpurea, Vymchaty, Aureo-marginata, Alba-variegata.

Less common are hybrids obtained by crossing two or more varieties: Bristle, Provencal, James, Zimbold, Diels.


Propagation by cuttings

The best effect is provided by the propagation of barberry by cuttings, and the cuttings must be cut at the beginning of summer from green shoots, since lignified cuttings cut in autumn take root much worse. It is better to take a stalk from the middle of a young shoot of the current season.

The length of the cutting is about 10 - 12 cm. The lower part is treated with a root stimulator. After that, the cuttings are planted in containers filled with a well-moistened mixture of sand and soil, deepening by about 1 cm.

For faster rooting, it is necessary to maintain soil moisture. It is useful to periodically spray the cuttings with a spray bottle. Cuttings overwinter in a greenhouse with an air humidity of about 85%. They can be planted in a permanent place after 1-2 years.


Reproduction

For reproduction of Ottawa barberry, all vegetative methods are used, as well as seeds. Reproduction by cuttings and layering is used more often.

In the northern regions of Russia, sowing with seeds is best done in the spring. In a warmer area, you can sow seeds in the ground in spring and autumn. To do this, proceed as follows:

  1. Ripe fruits are harvested in autumn.
  2. Wring out, washed and dried.
  3. They are planted in prepared soil, deepening by 1/3 of a finger.
  4. Cover with foil until it snows.

For spring sowing, preliminary stratification is carried out for 3 months at a temperature of about +5 0 C.

Reproduction by green cuttings is carried out in the summer. For this, young branches of the current year are used in plants of 3-5 years of age.


Use in landscape design

Barberry "Superba" can decorate even relatively modest areas. It is advised to plant it in the most illuminated places. Then the plant will look brighter and more expressive. It is possible to use the culture in both single and group plantings. It is planted near curbs and on alpine slides, as well as in the format of decorative hedges and in the design of house plots.
