Cactus is a tropical plant with fleshy stems, spines and no leaves. Most cacti just because of their appearance do not fit into everyday ideas about plants, because of this they cause conflicting feelings.

Meanwhile, cactus are the same normal family for the terrestrial flora, like everyone else. In this regard, there are so many guesses and speculations around them.

Cacti in Mexico are found at every turn. It is believed that Mexico "liked" cacti. In reality, this is not entirely true. It's not that Mexico cactuses like Mexico, but its climate didn't suit most other plants. In this country, cacti are the most common plant, which does not mean at all that they are found in Mexico at every turn. Mostly there are artificial plantings, and it is difficult to find cacti in the wild, as they grow too unevenly. Often, cacti form local "thickets" called populations. The sizes of such populations vary from several tens of meters to several tens of kilometers. Outside such populations, it is possible not to find cacti of this species, even if it is known that the range covers half the country. Moreover, the word "thickets" must be understood conditionally. The density of plants in populations also varies - it may be a single specimen for several square meters.

The habitat of cacti is the desert. It depends on which place is called a desert. In the imagination of many people who have never been to either Africa or America, deserts are the vast expanses of the sandy sea, dunes, camels. Obviously, in such deserts, cacti do not grow: with their slow growth, they would not have had time to appear on the surface, they would have already been covered with sand. But not all deserts are like the Sahara. Deserts are determined by the amount of annual precipitation (0-250 mm), a sharp daily change in temperature (a difference of up to 50 degrees), and a meager composition of flora and fauna (as a result of the climate). There is not a single desert in the world where cacti were its only inhabitants, as a rule, they are here in cohabitation with some grasses and small shrubs. Despite this, significantly more cacti do not grow in deserts. Most often they can be found in semi-deserts, steppes (prairies, pampas), savanna woodlands and tropical rainforests.

Tequila is a vodka made from cactus. Let's note right away: tequila is not made from cacti. It is obtained by distillation from the previously fermented juice of agave, a plant that is completely different from the cactus and belongs to a different family - agave.

Cacti grow in hot climates where there is never a winter. First, the winter season is inherent in almost all climatic zones. Another thing is that winter, for example, in northeastern Brazil, where the average daily temperature of the coldest month is much higher than zero. But this does not exclude the fact that in many habitats of cacti, not only negative temperatures are observed, but also other attributes of winter - frost, snow and ice. It should be noted that cacti have developed and exist in the earth's flora not as plants in hot countries, but as capable of growing in areas with insufficient humidity.

You don't need to water the cacti at all. Of course, the resources of the autonomous existence of these plants are also not unlimited, but it is better not to water the cactus at all than to water it every other day - this way it will last longer.

Cacti don't bloom. This is a myth born of the fact that some cacti begin to bloom quite late, while many may die before they bloom.

A cactus blooms only once in its life and then dies. This statement applies only to some species of agaves and cacti growing in conditions unsuitable for normal existence.

Cacti are a good remedy for computer radiation. It is not clear from where, but the myth started that cacti somehow attract and absorb computer radiation. Moreover, this belief spread so quickly that one can only wonder. It's worth looking into this. Most of the radiation does not come from the computer itself, but from the monitor, and 4/5 of this is emitted by the screen, and only 1/5 of the high-frequency waves pass from other sides. If the radiation propagates radially, then the cactus can absorb (even if it is so) only that part of the radiation that is directed at it. Much more effective and reliable are special protective devices built into the monitor tubes - grounded grids. Thus, the benefits of cacti in the fight against radiation are doubtful, but the harm to a plant from a computer is obvious.

It is better not to replant the cactus at all after planting. This is a very common opinion, based on an analogy with an aquarium: if the biosystem is established, then it is better not to disturb it. This is partly true. Since inept intervention will only harm the plant. Another argument in defense of this judgment may be the fact that in nature no one cares for cacti. But it should be borne in mind that in natural conditions, cacti are able to develop a fairly large root system without any restrictions. It is also important that the plant in the population is fully included in a specific ecosystem. Of course, such conditions cannot be found in houses. The volume of the soil mixture is limited, improper watering and drainage deteriorates its quality, the soil fauna is actually drowned out. If the cactus is not transplanted, "forget about it", then the roots of the plant will begin to gradually die off, depriving it of moisture and nutrition. This process can be relatively long and invisible to the untrained eye. At the same time, large plants can even bloom annually, though not so violently. Most often, this is how large melocactuses die. But not everything is so terrible! If the soil mixture was originally compiled correctly, and watering was carried out according to all the rules, cacti can exist without replanting for many years. Although their annual growth will be small, it is not much higher in the natural environment.

A cactus that does not grow in summer often dies in winter. A non-growing cactus is half dead, although some species can remain in this half-dead state for several years. In order not to lose a non-growing specimen, it is imperative to find out the reason why it does not grow - most often it is the loss of roots - and take the necessary measures.

In order for a cactus to bloom, it must be abundantly fertilized. The cactus must be fertilized to the extent of its needs, and they are much less than that of deciduous plants. Overfed, it will never bloom, just like a starving one. But cacti do not die from underfeeding, while overfeeding is often fatal for them: according to their physiological characteristics, they are not adapted to it.

Cactus spines are underdeveloped leaves. No one doubts that it is in cacti that thorns have a leaf origin, and at certain stages of development they contain chlorophyll. But this does not mean that thorns are modified leaves. Along with thorns, leaves are present in all plants of the subfamily of the Peres and some plants of the subfamily of Opuntia. Spines in cacti are modified kidney scales.

Each cactus should be planted in a separate pot. The nature of planting should be determined by expediency. If there are only 2-3 cactuses in the house, then the question of pots disappears. But it happens that there are many plants, then transplanting takes a lot of time only because you have to select an individual pot for each flower. But if there is a certain number of approximately the same age and requiring similar conditions for keeping cacti, then it is wiser to plant them in groups. But suppose that in separate pots these plants occupy the same area, then the volume of the substrate that each cactus can have increases immeasurably. With such a planting, in the process of development, the roots of strong plants will occupy free areas of the substrate under the weaker or younger ones. There are disadvantages when landing in a common vessel:
a) only plants of the same type should be selected for planting;
b) it will not be possible to take one plant, for example, to an exhibition, and then return it back;
c) there is a great risk of root pests and diseases.

Cacti do not get along well with other plants. This fact has not been scientifically proven. Moreover, there are examples of their peaceful existence with other plants in the natural environment. Despite this, the statement is close to the truth. Cacti do not get along well with other indoor plants. It's all about different conditions of detention: often cactus suffer from excessive moisture, which is created by flower growers for most indoor plants.

Cactus and succulent are synonymous. In fact, it is not the same thing: not every succulent is a cactus, although every cactus is necessarily a succulent.

If you look at cacti often, they will grow better. Examining your "hedgehogs" often enough, you can notice the upcoming troubles in time (attack of ticks, loss of roots, wounds) and warn them with appropriate measures.
