It is believed that cacti as a species stood out about thirty -five million years ago, and appeared in South America, later spread to the Northern Continent. Scientists know more than a million species of cacti, all of them are divided into four main groups: cross -fingers (the connection of cacti with deciduous plants), opunsium (stem plant with small fragile thorns), mahienic (distributed only in patagonia, externally they are similar to the venues, but the thorns are absent ), and cactus
(all other kinds of cacti, there are no leaves, mostly have a cylindrical or spherical shape).
To date, cactus for many people is a favorite pastime, they look after them, water, fertilize, and all this so that your favorite cactus grew up and develops, and blooms once or twice a year (most species), and this is happiness for a true flower grower. Some people buy cacti to use the supposedly useful property of this plant – the absorption of radiation. Unfortunately, this is a myth, cacti are not able to absorb any radiation, it will simply die slowly (rot from the inside), due to a lack of sunlight, so it is better to grow cacti on the windowsill of their house, apartment, rooms and necessarily on the sunny side. It is also necessary to maintain constant air ventilation, it is necessary for the good development of prickly plants.
Also, many residents of South America, in particular Mexicans, use some cacti for food, eat only fruits and stems (edible species of units). In the deserts they are used as a source of water, because in some large species in the stem may contain up to three liters of liquid.
Every day, scientists open a new type of cacti, crossing one plant with another. This is not easy to do, but if you succeed, it will be easier further, you can cross cacti with some berries, fruits (for example, crossing a cactus with raspberries, it turns out very beautiful and interesting).
Do not be afraid to breed cacti, you will definitely like it and will become the main and favorite hobby.
