Aztekium


GeneralitŠ°


This genus includes only two species of cactaceae originating from Mexico. They grow very slowly and the specimens over the years can reach 15-20 cm in diameter, also producing many side shoots; they have a globular body, gray-green in color, with 9-11 ribs, of which the most pronounced bear small areolas with white spines that come off over the years. In summer they produce white or pinkish tubular flowers, generally in the apical area. These cacti are not very common because the cultivation is quite difficult and the growth is very slow.

Exposure



The aztekiums love the semi-shady positions and fear too many hours of direct sun; in winter they can withstand short frosts if they are kept completely dry, to have a well-developed plant it is good to cultivate it in places with a minimum temperature around 10 ° C.

Watering



In the vegetative period, from March to October, water regularly, with small amounts of water and waiting for the soil to dry completely between one watering and another. With the arrival of cold weather, drastically reduce watering, to allow the plant to begin its vegetative rest. In spring and summer, provide fertilizer for succulent plants every 20-25 days, mixed with the irrigating water.

Ground


They need very well drained soils, mainly composed of sand and fine pumice or volcanic lapillus. It is not necessary to repot these plants that develop a fleshy root too often.

Multiplication


Generally these plants propagate by removing the shoots from the mother plant and rooting them in individual containers. If you want you can also sow the small black seeds, even if they are not always fertile.

Aztekium: Pests and diseases


Cultivating aztekium in poorly drained soil may favor the onset of root rot, which can quickly compromise the entire plant; excessive watering and poor air circulation can lead to uncontrolled cochineal development.
