Mammillaria: Home Care, Transplanting And Propagation, Species

One of the most popular cacti among florists is the mammillaria, which is unpretentious and undemanding in its care. These cacti are native to southern North America and also to Mexico, and in natural conditions they prefer to grow on chalky and calcareous rocks. Some species of Mammillaria can be found at a very high altitude, around 2.5 thousand meters above sea level. These cacti prefer to put down roots in rock crevices, in volcanic tuffs, and some species grow near the sea.

Mammillariae are not large, and their shape is mostly cylindrical and rounded. These cacti are very strongly pubescent. Mammillaria differs from other cacti in that on the surface of its stem are small papillae, from which grow small hair-like spines. This plant is highly resistant to cold and heat. But consider that there are also species that are extremely demanding to weather conditions.

Mammillaria in culture is a very popular cactus. But for it to grow and develop well under room conditions, it needs good care and optimal conditions for development and growth.

Brightness

This cactus is a light-loving plant, so it needs plenty of light. If the plant does not get enough light, it can die. A shrub will grow best on a southern balcony or loggia.

To make it feel well in winter, you should provide it with extra light by installing phytolamps.

Temperature regime

For the cactus to develop and grow normally, it needs moderate air temperature, namely from 15 to 25 degrees. In summer on hot days, it will need protection from the direct rays of the sun, as they can harm it. If the bush overheats, it will become shriveled or burns will appear on it. Shade the plant only when it is in a dry and unventilated place.

If the window is constantly open, the shrub does not need shade.

Dormant period

Wintertime Mammillaria has a dormant period. It is best to keep it cool (7 to 10 degrees) during this period. During the resting period, watering should be stopped. Those cacti, which stems have pubescence, during winter time must be kept at not less than 15 degrees.

If such bushes grow in a warmer place, they may suffer.

Watering

In winter and summer, mammillaria are watered differently. During the resting period, water very sparingly and infrequently so that on average it should be watered once every 15 to 20 days. In spring and summer, the number and abundance of watering increases. During the warm season, on average, the soil is moistened once every 7 days, but the final frequency of watering is influenced by weather conditions and the size of the container.

But be sure to remember to moisten the potting soil mixture only when it is completely dry. Otherwise you can harm the plant. It is best to water the mammillaria in the morning so that the surface of the potting soil can dry out in the evening. Exactly in the cold season it is very susceptible to overwatering of the substrate, although even in spring and summer period you can not allow the stagnation of moisture in the root system.

Feeding

Feed this plant only with special fertilizers for succulents and cacti.

Choose only liquid fertilizers. Mammillaria is not fed all year round, but in April-October. In winter, when there is a dormant period, all nutrition stops.

Potting Mammillaria

When the mammillaria is young, it is transplanted regularly once a year. When the plant becomes an adult, the number of transplants should be reduced to one every 2 years.

Such plants need a porous substrate that lets water and air through well. Prepared soil mixture should be sure to pour a small amount of gravel and brick crumbs. Do not put mulch in the substrate, because cacti are not recommended to grow in a soil mixture that contains too many nutrients.

Flowering

When growing the cactus in room conditions, it blooms regularly and quite spectacularly. Generally, the first buds form at the end of the dormancy period. The maturing buds on the bush can be found as early as January. In this case, start to water more abundantly from April and around March the first flowers should already be opening.

Bud development on the Mammillaria takes about four weeks, which is why the watering needs to be more plentiful and frequent but balanced at this time. Remember that during the maturation of the buds the plant should be placed on a window sill in such a way that direct sunlight does not reach the side of the plant where the flowers will open after a while. The side on which the bud is located should be turned so that it is in the shade. If this is not done, the bud may die.

Propagation

Many flower growers use shoots to propagate Mammillaria, because this method is simple and easy.

However, experts advise, once every few years to grow such a cactus not from a stem, but from a seed. The fact is that the shoots of this plant can degenerate over time.

Diseases and pests

The following problems may occur with mammillaria when growing it in room conditions:

  1. The Red spider miteHas settled on the bush. This pest can cause severe damage to the cactus, so you must start combating it as soon as it is detected. To get rid of the mite, as a rule, use special insecticidal preparations.

    You must use them within 15 days according to the instructions on the package.

  2. Cactus mites appeared on the plant . It is quite difficult to get rid of scutes, because the adults have a protective shell. That is why in the fight against such a pest can not do without pesticides, or more precisely, insecticides. Treatments with such a drug are carried out regularly according to the instructions for several weeks until all the insects are dead.

  3. Appearance in the root system of the bush nematodes. The matter is complicated by the fact that nematodes are underground on the roots, so it is not easy to detect them. In most cases, the affected bush has bubbles forming on the surface of the roots. To save the cactus, remove it from the substrate and cut off any bubbles. Then immerse the root system in very warm water for 10 minutes (about 50 degrees).

    Then sprinkle the roots with carbon powder and put the bush in a new pot and freshly disinfected substrate.

  4. The color of the stem has changed or it has become soft. In most cases this is due to rotting on the bush. Make sure the potting soil is very dry and adjust your watering.

Bad potting soil usually causes pests to infest the cactus.
