Mammillaria

One of the most popular cacti among flower growers is Mammillaria, which is distinguished by its unpretentiousness and undemanding care. These cacti come from southern North America, as well as from Mexico, and in natural conditions they prefer to grow on chalk and limestone rocks. Some species of mammillaria can be found at a very high altitude, about 2.5 thousand meters above sea level. Such cacti prefer to take root in rock crevices, in volcanic tuffs, and some species grow near the sea.

Mammillaria are not large, and their shape is most often cylindrical and round. These cacti are very pubescent. Mammillaria differs from other cacti in that on the surface of its stem there are small papillae, from which small hair-shaped spines grow. This plant is highly resistant to cold and heat. But it should be borne in mind that there are species that are extremely demanding on weather conditions.

Home care for mammillaria

Mammillaria is a very popular cactus in culture. But in order for her to grow and develop well in indoor conditions, she needs to be provided with good care and optimal conditions for development and growth.

Illumination

This cactus is light-loving, so it needs a lot of light. If the plant does not have enough light, then it may die. Best of all, the bush will grow on the southern balcony or loggia. To make him feel normal in winter, they provide him with additional lighting, for this they install a phytolamp.

Temperature regime

In order for a cactus to develop and grow within normal limits, it needs a moderate air temperature, or rather, from 15 to 25 degrees. In summer, on hot days, he will need protection from direct sunlight, as they can harm him. If the bush overheats, it will become wrinkled or burns will appear on it. The plant is shaded only when it is in a dry and unventilated place. If the window is constantly open, then the bush does not need to be shaded.

Dormant period

In winter, the mammillaria has a dormant period. Best of all, during this period, it is cool (from 7 to 10 degrees). During the dormant period, watering must be suspended. Those cacti, on the stems of which there is pubescence, in winter should be at a temperature of at least 15 degrees. If such bushes grow in a warmer place, they may suffer.

Watering

Mammillaria is watered differently in winter and summer. During the dormant period, the bush needs to be watered very sparsely and rarely, so, on average, the procedure is carried out 1 time in 15-20 days. In spring and summer, the number and abundance of irrigation increases. In the warm season, on average, the soil mixture is moistened once every 7 days, however, the final irrigation frequency is influenced by weather conditions and the size of the capacity. But it is imperative to remember that you should moisten the potting soil only when it is completely dry. Otherwise, you can harm the plant. It is best to water the Mammillaria in the morning, in this case, the surface of the soil mixture in the pot will be able to dry thoroughly until the evening.

Particular attention should be paid to watering the cactus in autumn and winter. Indeed, it is in the cold season that it is very susceptible to waterlogging of the substrate, although in the spring-summer period it is impossible to allow stagnation of moisture in the root system.

Top dressing

This plant is fed exclusively with specialized fertilizers for succulents and cacti. Moreover, they choose only liquid fertilizers. Mammillaria is not fed all year round, but in April – October. In winter, when a dormant period is observed, all feeding is stopped.

Mammillaria transplant

While the mammillaria is young, it is transplanted regularly once a year. And when the plant becomes adult, the number of transplants must be reduced to one in 2 years.

Such plants need a porous substrate that allows water and air to pass through well. It is imperative to add a small amount of gravel and brick chips to the finished soil mixture. Humus cannot be poured into the substrate, because it is not recommended to grow cacti in a soil mixture that contains too many nutrients.

Bloom

When growing a cactus indoors, it blooms regularly and quite effectively. As a rule, the formation of the first buds occurs at the end of the dormant period. Ripening buds on the bush can be found already in January. In this case, from April, the flower begins to be watered more abundantly, while the first flowers should already open around March.

The development of buds on mammillaria lasts about four weeks, it is because of this that during this period watering should be more abundant and frequent, but balanced. Remember that during the ripening of the buds, the bush should stand on the windowsill in such a way that direct sunlight does not fall on the side of it, on which flowers will open after a while. The side on which the bud is located is turned so that it is in the shade. If this is not done, then the bud may die.

Reproduction

Many flower growers use shoots to propagate mammillaria, because this method is distinguished by its simplicity and ease. However, experts advise that once every few years such a cactus should be grown not from the stem, but from the seed. The fact is that the shoots of this plant can degenerate over time.

Diseases and pests

When growing mammillaria in room conditions, the following problems may arise with it:

1. Settled on a bush red spider mite... This pest can cause severe harm to the cactus, so you need to start fighting it immediately after it is detected. In order to get rid of a tick, as a rule, special insecticidal preparations are used.They need to spray the bush for 15 days in accordance with the instructions, which can be found on the package.
2. Cactus appeared on the plant scabbards... It is quite difficult to get rid of scale insects, because adults have a protective shell. That is why, in the fight against such a pest, one cannot do without pesticides, or rather, insecticides. Treatments with such a drug are carried out regularly in accordance with the instructions for several weeks until all the insects die.
3. The appearance of a bush in the root system nematode... The matter is complicated by the fact that nematodes are located underground on the roots, so it is not so easy to detect them. In most cases, bubbles form on the surface of the roots in the affected bush. To save a cactus, remove it from the substrate and trim off any bubbles. Then immerse the root system in very warm water (about 50 degrees) for 10 minutes. Next, sprinkle the roots with charcoal powder, and plant the bush in a new pot and fresh, disinfected substrate.
4. The color of the trunk has changed or it has become soft... In most cases, this is due to the appearance of rot on the bush. Dry the potting soil well and adjust the watering.

As a rule, harmful insects settle on a cactus due to a poor quality soil mixture.
