is a tropical plant with fleshy stems, in thorns and without leaves. Most cacti only because of their appearance do not fit into the ordinary ideas about plants, because of this they cause contradictory feelings.
Meanwhile, cacti are just as normal for the terrestrial flora as any other family. They have all the organs that ordinary plants have. Obviously, cacti have special features that are characteristic only of them and qualities. In this regard, around them there are so many conjectures and conjectures.
Cacti in Mexico are found at every step.
There is an opinion that Mexico “liked” cacti. In reality, this is not entirely true. Not that Mexico liked cacti, but its climate did not suit most other plants. In this country, cacti are the most common plant, which does not mean that they are found in Mexico at every step. In general, there are artificial plantings there, and in the wild state it is difficult to find cacti, 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, one can not find cacti of this species, even if it is known that the area covers half the country. And the word “thickets” must be understood conditionally. The density of plants in populations also varies – this may be a single specimen of several square meters.
Habitat of cacti – desert.
This is looking at what place to call a desert. In the imagination of many people who have never been in Africa or in America, the deserts are the vast expanses of the sandy sea, dunes, camels. It is obvious that in such deserts cacti do not grow: with their slow growth, they, without having had time to appear on the surface, would already be covered with sand. But not all deserts are like the Sahara. Deserts are determined by the number of annual precipitation (0-250 mm), a sharp daily change in temperature (difference up to 50 degrees), a meager composition of the flora and fauna (as a consequence of the climate). There is no desert in the world, where cacti were its only inhabitants, as a rule, they are here in cohabitation with some herbs and small shrubs. Despite this, a much larger number of cacti grows not in deserts. More often they can be found in semi-deserts, steppes (prairies, pampas), savannah forests and moist tropical forests.
Tequila – vodka from cacti.
Immediately notice: tequila is produced not from cacti. It is obtained by distillation from the previously fermented agave juice, a plant that is not at all like a cactus and belongs to a different family – agave.
Cacti grow in a hot climate, where there is never winter.
First, the winter season is inherent in almost all climatic zones. Another thing is that winter, for example, in the northeast of Brazil, where the average daily temperature of the coldest month is much higher than the zero mark. But this does not exclude the fact that in many cactus habitats there are not only negative temperatures, but also other attributes of winter – hoarfrost, snow and ice. It should be noted that cacti have developed and exist in the terrestrial flora not as plants of hot countries, but as capable of growing in areas with insufficient moisture.
Cacti can not be watered 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 in a day – so it will last longer.
Cacti do not bloom.
This is a myth born from the fact that some cacti start to bloom quite late, and many can die before their flowering.
The cactus blooms only once in its life and then dies.
This statement applies only to certain types of agaves and cacti growing in conditions that are not suitable for normal existence.
Cacti are a good remedy against computer radiation.
It’s unclear where, but the myth that cacti somehow draws and absorbs computer radiation is gone. And this belief has spread so quickly that it remains to be surprised. It is necessary to understand this. Most of the radiation does not come from the computer itself, but from the monitor, with 4/5 of this radiating screen, and only 1/5 of high-frequency waves pass from other sides. If the radiation spreads radially, then the cactus can absorb (if it is even so) only that part of the radiation that is directed at it. Much more effective and reliable special protective devices built into the monitor tubes – grounded grids. Thus, the benefits of cacti in the fight against radiation are questionable, but the damage to the plant from the computer is obvious.
It is better not to transplant the cactus after planting.
This is a very common opinion based on the analogy with the aquarium: if the biosystem is established, then it is better not to disturb it. This is partly true. Since inept intervention will only damage the plant. Another argument in defense of this proposition may be the fact that nobody cared for the cacti in nature. But it is worth considering that in natural conditions, cacti can develop a fairly large root system without any restrictions. It is also important that the plant in the population is wholly included in a particular ecosystem. In the homes of such conditions, of course, can not be found. The volume of ground mixture is limited, improper irrigation and drainage deteriorates its quality, the soil fauna is virtually drowned out. If the cactus is not transplanted, “forget about it,” then the plant roots will gradually die off, depriving it of moisture and nutrition. Such a process can be a relatively long and inconspicuous inexperienced eye. Large plants can even bloom annually, although not so violently. Most often this is how big small cacti die. But not everything is so terrible! If the soil mix was originally made correctly, and irrigation was carried out according to all the rules, cacti can exist without transplantation for many years. Although their annual growth will be small, but in the natural environment, it is not much higher.
A cactus that does not grow in summer, often dies in winter.
Not growing cactus, half dead, although some species can persist in this half-dead state for several years. In order not to lose a non-growing copy, it is necessary to find out the reason why it does not grow – most often this is the loss of roots – and take the necessary measures.
In order for the cactus to blossom, it must be fertilized abundantly.
The cactus should be fertilized to the extent of its needs, and they are much less than that of deciduous plants. Overfed, it will never bloom, as well as starving. But cacti do not die from underfeeding, while overfeeding for them is often fatal: 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 the spines are of leaf origin, and at certain stages of development they contain chlorophyll. But this does not mean that spines are modified leaves. Along with thorns, leaves are found in all plants of the subfamily Perovski and parts of the plants of the subfamily Opuntia. The spines of cacti are modified kidney scales.
Each cactus should be planted in a separate pot.
The nature of the planting of plants should be determined by expediency. If the house only 2-3 cactus, then the issue with pots disappears. But it happens that there are a lot of plants, then the transplant takes away a lot of time only because it is necessary to select an individual pot under each flower. But if there is a certain amount of approximately age-old and requiring similar conditions for cacti, it is more reasonable to plant them in groups.But suppose that in some pots these plants occupy the same area, then the volume of substrate that every cactus can have is immeasurably increasing. With this planting in the process of development, the roots of strong plants will be taken by the free areas of the substrate under the weaker or younger ones. When planting in a common vessel, there are disadvantages:
a) only plants with the same type of care should be selected for planting;
b) it will not be possible to take one plant, for example an exhibition, and then return it back;
c) the risk of root pests and diseases is high.
Cacti do not live well with other plants.
This fact has not been scientifically proven. In this case, 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. The whole thing is in different conditions of content: often cactus suffers from excessive humidity, which is created by flower growers for most indoor plants.
Cactus and succulent are synonyms.
Actually, this is not the same thing: not every succulent is a cactus, although every cactus is necessarily succulent.
If you often look at cacti, they will grow better.
Considering your “hedgehogs” often enough, you can notice advancing troubles in time (attack of mites, loss of roots, wounds) and warn them with appropriate measures.
