Cereus is a bright representative of the cactus family. Russian flower growers appreciate it for its rather rapid growth, large size, and unusual appearance. So, for growing at home, a certain variety of it is suitable - Peruvian Cereus. We will talk about the rules of landing and care in the article.
Cereuses are long-lived by nature: life expectancy reaches 300 years. In form - tree-like, branched, very bushy. This form is called monstrous. It grows up to 20 m in height. The root system develops powerful. Large areola covered with felt. The thorns of the flower are stiff, their length is 3 cm. The central thorns are in the form of an awl, much more - 10 cm.
The cactus blooms in May or early June. The disclosure of most species occurs at night. By the way, flowering is very short - wilting occurs within a day. It is for this reason that at home it is difficult to achieve a massive disclosure of cacti.
For Cereus Peruvian to bloom, favorable conditions are needed. There are only two of them: long daylight hours and a rest period.
Flowering "Peruvian" may not occur for several reasons:

The opening of a flower is greatly influenced by light.
Well, if the place in the house is adequately lit by the sun's rays, otherwise you can use additional illumination - a lamp.
In addition, the “Peruvian” needs a certain amount of moisture to safely survive low temperatures (autumn-winter season). When the cereus blooms - depends on the care and maintenance. Usually this moment falls on the last days of spring, as well as summer or autumn. Just at the time of ripening, the fruits turn red, sometimes yellow, and their sizes reach 10 cm. They are distinguished by smoothness, a pleasant aroma. By the way, the fruit of the Peruvian cactus is edible.
The main characteristics of this variety:

- the shade of the flower is white;
- the form is monstrous;
- the fruit is round, the shade is yellow or orange;
- seeds are black;
- the stalk is deeply divided (into 6–8 ribs);

Rules for care and reproduction

The variety tolerates heat, drought, tolerates temperature jumps. Wintering starts at 8–10 degrees. Fresh air has a positive effect on growth, so it is recommended in summer and in the first autumn days to put the cereus on the balcony.
Most often, the procedure is carried out in the summer, closer to the cold it stops altogether in order to avoid rotting of the root system. It is undesirable to water with cold as well as hard water.

In the wild, the “Peruvian” propagates with the help of seeds; in home growing conditions, flower growers have revealed another method - cuttings.
Time is April-May. The tank is filled with sandy soil, a seed is sown there, watered a little and sent to a dark place before germination. The first seedlings appeared - the container is rearranged on the bright side, where the temperature is not lower than 20 degrees. After the first spines appear, a pick is allowed.
Time is spring-early summer. First of all, they start cutting cuttings: one shoot is cut into pieces. For 4 days it goes to dry. A low container is used for the plant, where moist loose earth is laid out. Cuttings are deepened a little.
After 3 weeks, the appearance of roots is observed, then you need to wait until the entire root system is strengthened, after about two weeks the cactus can be transplanted into separate containers.
