Pereskia


Pereskia has the origin of cactus plants that are common in Central and South America. In the past, cacti consisted of leaves, and in too dry climates in deserts, they began to turn into thorns. And the central part of the plant is capable of performing all the functions of the leaves.

Pereskia is a large shrub or low tree with thorny stems and green or purple leaves. Islets with spines are located in the axillary areas of the leaves; they can be singly or in bunches. During growth, in nature, pereskii with the help of thorns clings to the trunks of various trees. Over time, the leaves fade, dry out, and crumble at rest.

Caring for ossification at home

Location and lighting

It is important to observe the correct lighting regime: the peresky loves light, so it is better to place it on the southern windowsill. In order not to burn the leaves, when the sun is too active, the plant must be shaded. In summer, pereskiy can be taken outside, but the container with the plant should be located so that precipitation does not fall on it. It can be placed under a canopy or in another covered place.

In the absence of such an opportunity, it is necessary to actively ventilate the room in the summer, so that the plant receives more air. In winter or autumn, it is also necessary to provide good lighting. In the spring, the light becomes more, the plant must be taught to this gradually, so as not to burn the leaves.

Temperature

Pereskia feels favorable at a temperature of 22-23 degrees, while it is desirable that the cactus receive fresh air. In the autumn, this figure must be reduced to 15 degrees, the pereski is prepared for a state of rest, in the winter they are kept cool, from 12 to 16 degrees, but not lower than 10 degrees. The room should be regularly ventilated and well lit.

Air humidity

Pereskia is able to tolerate dry air, but the leaves acquire a beautiful and healthy appearance only with periodic spraying, for this they use soft water.

Watering

In spring and summer, watering is carried out as the soil surface dries up. Since autumn, the amount of watering is reduced, and in winter the plant is rarely watered to prevent leaf shedding.

The soil

For growing pereskii, soil of a fertile and loose type is used, humus can be added to it. Usually, several types of soil are combined: leaf, clay-soddy, humus and sand, the latter should be one part less (2: 2: 2: 1).

Top dressing and fertilizers

Starting in spring, the plant is fed twice a month. For this, special fertilizers for cacti are used, only the concentration is made by half. To prevent unwanted development and growth in winter, no feeding is done. When using fertilizers of a mineral type, nitrogen should be in a minimum amount, otherwise the roots will begin to rot.

Transfer

The transplant is carried out as the plant develops, usually up to several times a year. Pereskia roots are powerful, so large containers are selected every time. Drainage must be laid at the bottom. After the plant is transplanted, it begins to grow actively.

Reproduction of pereskii

Pereskia is able to multiply using seeds or cuttings. Seeds are planted in containers in the spring, while maintaining the temperature in the range of 20-22 degrees. Cuttings of the stem type are cut in the spring or summer period, they are immersed in a moist perlite or peat composition, and then covered with a film. In order for rooting to occur quickly, a temperature of 25-28 degrees is observed. Roots can emerge and develop in water, which takes about 3 weeks. After that, they are seated in small containers.

Diseases and pests

With an excessive amount of liquid, especially in cold weather, the neck and roots begin to rot. This can happen in the absence of drainage or insufficient drainage. To prevent such a problem, you must carefully monitor the implementation of watering so that it is not excessive.

In some areas of the stem, mildew of a softened type may appear, this disease is called gray rot. This disease occurs from high humidity and when circulation does not occur. To combat the disease, it is necessary to change the conditions of detention, as well as to process the plant with special compounds.

Mealy worms extract juice from the leaves and all stems of the plant, as a result, it dies. To combat such pests, they are removed with a hard-looking brush. If there are a lot of plants, then it is necessary to carry out additional processing with special means that can prevent the development of cocoons.

There are also other types of pests, for example, mites or thrips, they are capable of infecting all plant organs, flowers, leaves, stem. To combat such a problem, pereskii are processed with special means.

Popular types

After the time elapses at the bottom of the plant, the leaves crumble, and areas with thorns remain, up to 3 pieces on each former leaf. In this case, the color of the areola turns brown, and in its lower part there are two curved spines. At the end of the summer period, and by the beginning of autumn, on the processes of the young species, a color that has a fragrant smell, a cup-shaped shape, and a white-yellow color with a pinkish tinge bloom.

The disease is manifested by infection of flowers, ovaries, branches and fruits. During the flowering period, the disease affects flowering shoots. Flowers and leaves wilt and dry out. They remain on trees for a long time, but they look like burnt.

The cause of the disease is the microscopic fungus Monilia cinerea. He spends the winter period in affected branches and shoots of the same age, as well as in fruits that have fallen to the ground.

Often, the disease begins to develop in cool and humid weather, fog and dew during the flowering period.

In the summer, the fungus continues to infect the shoots and branches of trees, gradually reaching the fruits. At first, you can see a small brown spot on them. The increase in its size occurs rather quickly, and after a while the entire fetus is affected.

The disease can appear as a result of damage to the fruit by insects such as goose, weevil, moth. In turn, an infection can get to the site of damage, which will contribute to the development of moniliosis.

Cactus blooms - what species is it?

Breeding thorny pets is often perceived as a simple game that does not require regularity or increased attention. However, when people realize how reluctant and rarely a cactus blooms, they urgently need professional advice and clear instructions. Almost all species of this plant do not have leaves and can be of various shapes. Healthy stems are usually fleshy, with a unique stem pattern for each species.

Blooming cacti. Types and features

The appearance can vary significantly between cultivars: the surface can be smooth, with tiny bumps, covered with pits or ribs. Familiar needles can also look different, the spines can be thick (up to 1-2 mm) or similar to soft curly hair. If a cactus blooms, its buds can have absolutely any color - from white to crimson and dark purple. The shape of the flowers is tubular or funnel-shaped. The plant belongs to self-pollinated species, capable of producing good seed for planting material. Some members of the thorny family bloom only at night, others only in the morning. A well-chosen collection can always present a colorful corner in an apartment or mini-greenhouse. When growing blooming cacti, the names have to be memorized in Latin, so as not to accidentally spend a lot of time on an uninteresting variety. It is necessary to try to select such varieties of pets so that you can keep them in the same conditions. It will be quite difficult to equip a personal greenhouse for each tiny pot.

Such different thorns

There are two large groups of cacti: desert and rainforest. Accordingly, the conditions of their detention will be different. For home cultivation, any dwarf species is suitable, which does not have to be attached to a clinic or post office in a few years. If the grower has a desert cactus, it blooms well and for a long time, but in the second or third year. Forest representatives require more moisture and shade, but they also delight with their buds much more often.

Popular desert varieties of thorny pets: the Cereus family, echinocactus, prickly pear, rebutia and whip-like aporocactus. Forest options for greenhouse residents suggest growing zygocactus or ripsalidopsis. A unique representative of the desert group - pereskia, it has glossy leaves and, of course, this cactus blooms with delicate, pleasantly smelling pale yellow inflorescences.

Species suitable for beginners

Epiphyllum is the easiest and most abundant blooming cactus to care for. The color of the buds can be from crimson-red to lilac-violet, white or pale blue. In the summer, the plant is placed in a bright, but not hot place. Once every few days, you need to spray with not very cold water, otherwise the cactus will lose all its color. When the last petals fall off, watering is reduced. If a transplant is required, then it is best carried out in the month of April, when the natural growth of the cactus begins. The plant can be propagated by cuttings into light soil from leafy soil, turf and clean sand. Almost any variety of cactus can be made to bloom with a little effort and patience.


Cacti and other succulents

Before Columbus discovered America, the inhabitants of other continents had no idea what cacti, although several of their species at that time were quite common in the subtropical belt of our planet, not only in America.

These include branching leafy tree species that have received the generic name PERESCIA.


But when we say the word "cactus", it is associated with succulents spherical or cylindrical. These are the overwhelming majority of representatives of the vast family cactus... Sometimes cacti they call plants similar in shape native to Africa, but this is a completely different branch, most of which belongs to the milky, well known to us by euphorbia or super succulents, among which the most famous are lithops and conophytums.


Therefore, "everyone cactus - this is succulentbut not everyone succulent - cactus". The very definition"succulent"(from Latin succus - juice) refers to plants capable of storing moisture in the tissues of their stems. This ability of stems and their biomorph was the result of centuries of struggle cactus for survival in an arid climate with a high level of solar insolation. In the process of evolution, protection from the hot rays of the sun began to be provided by the ribbed structure of the stems together with the shading bunches of spines on the areoles, and the fragile growth tissues at the tops learned to protect themselves with dense fluff or multiple bristles.


Try to direct a beam of light slightly deflected from the vertical to such a stem and you will make sure that half of it, and in spherical forms more than half of the stem is in its own shadow, and the illuminated edges of the ribs are only for a short time (remember the rotation of the Earth) are directly affected directed rays of the sun. As for the supply of moisture by plants, then large-sized cacti it can provide their vital activity for one to two years in the absence of atmospheric precipitation and a low level of relative humidity. At the same time, it is necessary to mention one more developed ability cactus: close the respiratory stomata of the epidermis at high temperatures during the day, thereby sharply reducing the level of transpiration, and open them during cool night hours, when the moisture consumption during the respiration of the plant is insignificant.

So, cacti - natives of America and only America! From Canada in the north to Patagonia and the Brazilian Highlands in the south - this is their area of ​​distribution. As a rule, these are high-mountain, treeless plains with a pronounced dry period, where cacti grow from ocean coastal areas to an altitude of 4500 m above sea level. m. Their appearance in the natural conditions of the subtropical zone of Europe, in India and even in the Crimea is the work of man and the adaptive ability of the plants themselves.


Its appearance, variety of shapes, colorful palette of prickly outfit and flowering cacti at all times attracted people of various social strata, and for many, the study and systematization of this family has become a matter of life.

Folk remedies for combating moniliosis

From folk remedies for combating moniliosis, we can offer you an autumn treatment of fruit trees with a solution of 1 kg of urea in a bucket of water. For spraying each adult plant, about half a bucket of the drug is consumed. For better "stickiness", you can add 40 grams of dishwashing detergent to the solution.It is necessary to wet all the leaves on both sides and all the branches of the tree, and after the leaf fall, you need to cover all the litter in the near-trunk circle with a thick layer of straw: the urea solution will clean the fungus from the branches and leaves of the tree, and straw mulch will preserve the pathogens that have not died during processing in the soil. In addition, mulch will serve as a good protection for the root system of the tree from winter frosts. In the spring, before the start of sap flow, you can once again process the fruit trees with a urea solution.
