is difficult even to believe that these plants, consisting of a bloated from the water reserves of the stem, fairly close relatives ... cloves!Yes, the family of the cactus belongs to the order of clove.The leaves of the cactus are reduced to the rough, woolly hairs, papillae, and the like (the exception - Pereskia), they are usually collected in the areola (a kind of center outlets of thorns), with the central and radial spines, many species very different from eachother lengths, colors and even the structure;it is not surprising that the stem had unwittingly take on the physiological functions of leaves: this is where photosynthesis and transpiration.

Many cactus species are very beautiful in bloom, but for flowering you need to create them for special conditions in the period of rest.

Different species of cactus in the wild are found in different environments, there are cactus desert (most of them), there is a mountain, there is forest.Of course, the origin of the imposed its own specific requirem

ents on these plants to the environmental conditions in the rooms.

General for the maintenance of all cacti recommendations:

requirement to moisture: for even the most water-loving species will be sufficient watering once a week, slightly more frequent in the hot summer sun, it can be quite abundant opportunities provided moisture outflow.We can not allow the accumulation of moisture in the substrate.Cacti, contained in plastic containers, watering less frequently than growing in clay pots.Water must be warm and soft tap - defended at least during the day.Volume (increase or decrease) of irrigation can be changed only gradually, sudden changes are extremely undesirable.

Temperature range: normal for the vast majority of flowering cactus is necessary to ensure the winter cold (about 10 ° C, for some - from 5 ° C).

Light regime: very light-requiring, they may be exposed to direct sunlight.Cactus is necessary to ensure maximum coverage.

requirement to soil: cacti require slightly acidic soil reaction (pH 4.5-6), a typical mixture is prepared from the coarse sand containing a large percentage of gravel (possibly domeshivanie brick chips, not only provides the necessary porosity, but also absorbs moisture)sheet metal and clay and sod land in equal parts with obligatory addition of charcoal as a preventive agent against root rot.Fertilizers are made in dry form.One of the main nutrients needed cacti is phosphorus, so the separate addition of superphosphate and other phosphate fertilizers will not be superfluous.It is also desirable to add lime, not only conducive to the supply of nutrients, but also helps normal growth of spines, bristles and hairs, but to use it you need to carefully: as a substance which changes the acidity of the soil much - only in conjunction with having acidifying properties of fertilizers.

Reproduction: cuttings, the children, at least - by grafting (in a way very interesting instances can be created).

Features: for alpine and desert cactus desirable summer outdoor maintenance, such as on the balcony or on a shelf, fastened to the window sill, but need to be protected from rain and dust.
