Bubble (Latin Physocarpus) - a genus of ornamental deciduous shrubs of the Pink family. The genus includes 14 species, distributed mainly in East Asia and North America.
Popular species and their characteristics
Bubbles is a highly decorative plant, often used for landscaping household and summer cottages. The most common are two types - the Amur pemphigus and the Kalinoliforne pemphigus.
* The Amur bubble plant (Latin Physocarpus amurensis) is a shrub up to 3 m high with a wide spherical crown. Leaves on the upper side are dark green smooth, on the inside - pubescent with a grayish tint. The fruits are red. Under natural conditions, the Amur puscarp grows on rocky slopes, undergrowth of mixed forests, in thickets of bushes and on rocky ridges of ridges. The Amur bilberry is a light-loving mesophyte, calcephyte, methotroph, microtherm and an assembler of undergrowth and shrub plantings.
* Kalinolistny blister (Latin Physocarpus opulifolius) is a shrub up to 3-4 m high with a wide rounded crown and flaky bark. The leaves are green, three or five-lobed, in autumn they acquire a golden yellow color. The flowers are small, whitish-pink or white, collected in globular umbrellas. The fruit is reddish in an immature state, while when ripe it is reddish-brown. Blossoming bladderwort in early summer. There are several decorative forms of the described species, differing only in the color of the leaves.
Growing conditions
Bubbles are unpretentious, they can grow without problems both in sunny and semi-shaded areas. Exception: varieties "Darts Gold" and "Diabolo", they develop well only in intensively lit areas. Fertile, well-drained, neutral or slightly acidic soils are preferred. bladders have a negative attitude to swampy, saline, waterlogged and highly acidic soils. Also, the culture does not accept lowlands with an accumulation of melt water and cold air. Plants are distinguished by increased wind-resistant properties, relatively frost-hardy, but in severe winters they can freeze to the very root.
Application
Often, vesicles are used in group and single plantings along railways and along highways. Plants are also suitable for creating hedges, both freely growing and shaped. The vesicle is decorative throughout the gardening period, but in winter the plants do not lose their attractiveness.
Reproduction and planting
The bladders are propagated by seeds, cuttings, layering and dividing the bush. Seeds are sown in autumn or spring. In the latter case, with a preliminary stratification lasting one month. Good results are obtained by the reproduction of the vesicle by layering. To do this, a healthy and strong lower shoot is bent to the ground, placed in a prepared groove, pinned with wooden brackets (metal brackets are not recommended), sprinkled with soil and watered abundantly. It is advisable to carry out this procedure in the spring, so that by the fall the layering has formed a good root system. At the beginning of September, the layers are separated with a shovel and transplanted to a permanent place. For the winter, young plants are covered with a thick layer of peat or humus.
Cutting is an equally effective breeding method for the culture in question. Cuttings cut from green shoots of the current year are used as planting material. Before planting in the substrate, the cuttings are treated with growth stimulants. The substrate is composed of sand and peat. After planting, the substrate is watered abundantly, and the cuttings are covered with plastic wrap. Caring for cuttings consists in systematic airing and watering. Rooted cuttings are transplanted to a permanent place next spring.
Care
The vesicles do not need special care, they adapt well to any growing conditions. However, regular watering, feeding, weeding and loosening the near-stem zone will not harm the plants, but will only benefit.
Because they grow rapidly, they require sanitary and formative pruning. This procedure allows not only to form a beautiful crown, but also to stimulate branching, which is also important. The cuttings of the bladderworms are painlessly tolerated, easily restored. Pruning is carried out in early spring, before bud break. To obtain a fountain-like shape in the vesicles, all thin shoots are cut off at the very base, leaving 5-6 stronger and healthier shoots.
The bladderworms respond positively to feeding. In the spring, the plants are fed with mullein, ammonium nitrate and urea, in the fall - with nitroammophos. The culture is resistant to diseases and pests, therefore it does not need preventive treatments.

Bubble Smut In Corn
Bubble smut attacks corn in most of its cultivation areas. It differs from the dust smut in that it manifests itself in the form of galls (as pathological formations are called) on all organs of corn. Often such galls can be seen on cobs with leaves. The most susceptible to this ill-fated misfortune, corn is considered at the stage from the moment of throwing out panicles and up to the phase of milk ripeness, therefore, during this period, special care should be taken, otherwise the loss of ur
