Mammillaria: characteristics, habitat, cultivation, uses and species
Mammillaria is a genus that constitutes the largest group of perennial cactus species belonging to the Cactaceae family. This group of plants consists of more than 350 species, characterized by the bulbous shape of their short, cylindrical body.
Native to central Mexico, these plants are characterized by their small size, prolific growth, and the presence of tubers, or mammillas. In fact, their bodies lack ribs, but are covered in these conical formations, distributed spirally throughout the plant.
A peculiarity that distinguishes this genus of cacti is the areoles covered in silky, robust spines. These spines are arranged around the star-shaped tubercle. From these structures emerge the attractive flowers in various colors, including white, yellow, pink, red, and purple.
Most of these species are medium to small in size, with small white, green, or red berries. These cacti are easily propagated and are regularly sold in pots for ornamental and decorative purposes.
From an ecological perspective, most of its wild populations are threatened or endangered. This genus, endemic to Mexico, has lost significant natural habitat due to its high level of extraction for illegal marketing purposes.
General features
Appearance
Most species in the genus Mammillaria have tubular cacti that are 2 to 5 cm thick and 12 to 15 cm tall. In fact, each foot develops numerous basal shoots that grow firmly or creepingly, establishing small, isolated colonies.
Caule
The stems consist of small, conical tubercles, 0,3 to 0,5 cm long, that develop 15 to 20 lateral spines, which are fragile and pale yellow. It also develops 1 to 3 firmer central spines, some curved and dark in color.
At the base of each mammillaria, new apricots and flower buds emerge. In fact, in the genus Mammillaria , the areoles are divided into two sections: the apex, where the spines emerge, and the base, where the apricots and flowers emerge.
Flores
The flowers are relatively larger than those of the mammillas. They emerge at the base and open above the lateral spines. The numerous petals have the characteristic colors of each species, and the center features multiple yellow stamens and a multi-lobed stigma.
Fruits
The fruits are small, fleshy, conical capsules, reddish-brown or orange in color. Each fruit contains between 5 and 20 ovoid, slightly leathery, dark-hued seeds.
Taxonomy
– Kingdom: Plantae
– Division: Magnoliophyta
– Class: Magnoliopsida
– Order: Caryophyllales
– Family: Cactaceae
– Subfamily: Cactoideae
– Tribe: Cacteae
Genus: Mammillaria Haw.
Etymology
– Mammillaria : the generic name derives from the Latin " mammilla ," meaning " tuber ," in reference to the modified characteristics of the stem or tuber of the genus.
Habitat and distribution
Members of the genus Mammillaria are native to the Americas, specifically Mexico, the southern United States, the West Indies, and the coast of Venezuela. Guanajuato, Hidalgo, and Querétaro are the Mexican regions with the highest concentration of endemic varieties and species.
These cacti are unique to desert ecosystems and are characterized by their tolerance to wide temperature ranges, both cold and hot, and their low humidity requirements. Thus, they adapt and survive in extreme desert climates and very arid environments where other species cannot survive.
Propagation
Mammillaria cacti reproduce through seeds or vegetatively by dividing the basal shoots. The difference between the two methods is related to the propagation time and the genetic variability obtained when using seeds.
Semente
Seeds are selected from ripe fruits of healthy, vigorous plants, free of pests, diseases, or physical damage. The fruits are allowed to dry in the air or placed between absorbent paper to speed drying and facilitate seed extraction.
The best time to sow seeds is during the cool months of March and April, distributing the seeds in a loose, well-drained substrate. Germination trays or shallow pots can be used, maintaining moisture and trying to cover the seeds with a thin layer of substrate.
It's advisable to cover each container with plastic to ensure constant temperatures and prevent the substrate from drying out. Place the containers in a shaded location with an average temperature of 21°C and continuous humidity until germination begins.
Germination occurs within 30 to 60 days or more, at which point it's time to remove the plastic and place the container in partial shade. This process occurs gradually, so moisture and shade must be provided for seeds that haven't yet germinated.
Once the plants have reached a certain size and are firm enough to withstand handling, they can be transplanted into individual containers. It's important to keep in mind that seed propagation is a slow process, so it can take more than a year to transplant.
Basal outbreak division
Basal shoots are new structures that include roots, stems, or buds that arise from the base of the parent plant. These shoots usually have small adventitious roots that promote the development of the new plant.
The buds are separated with a sharp, disinfected tool to avoid cross-contamination. Once separated from the mother plant, the seedlings are sown directly into a loose substrate, avoiding irrigation for the first 15 days.
If the bud doesn't have roots, it's allowed to dry for 7 days before transplanting. After the basal bud is transplanted, the new plant is managed like an adult plant, with occasional watering and increased light.
Cultivation
Transplant
Mammillaria cacti need to be transplanted from time to time to free up the root system and promote growth. Transplanting is necessary when, despite perfect watering, fertilizer, and sun exposure, the plant has slowed its growth rate.
Furthermore, transplanting monitors the health of the roots, removing damaged or diseased tips. When part of the root system is discarded, it's not advisable to water the plant to promote effective root healing.
The ideal substrate for this type of cactus is one part coarse sand or perlite and two parts compost. When planting, it's important to keep the drainage hole clear, as watering is essential for these plants.
Clay pots are recommended, as they allow air circulation between the substrate and the outside. Furthermore, they should be wider than they are deep, as the root system expands laterally.
Rega
Irrigation should be applied when the substrate is completely dry. An average watering schedule would be once a week during spring and summer and once a month during fall and winter, depending on temperature and humidity.
During the winter, it is advisable to suppress irrigation unless the plant shows signs of physiological damage. Furthermore, it is necessary to avoid keeping the substrate too moist, as Mammillaria is very susceptible to excess moisture in the substrate.
Lighting
Like all cacti, Mammillaria requires full sun exposure throughout the year. Ideally, keep it facing south and avoid north-facing exposure, which can cause burns in young plants.
Temperatures during spring and summer can range between 15 and 25°C, while in autumn and winter they can range from 10 to 15°C. Avoid temperatures below 10°C. In low temperature conditions, it is advisable to keep the plant dry and ventilated.
Spreading
During the spring and summer, it's advisable to apply a liquid fertilizer every 25 to 30 days, which promotes the cactus' development and flowering. However, during the fall and winter, fertilizer application is not recommended, as the plant is in vegetative dormancy.
The suggested formula to ensure optimal growth and vigorous flowering is a balanced 30:30:30 nitrogen, phosphorus, and potassium fertilizer. Likewise, regular application of trace elements required for specific deficiencies, such as boron, copper, iron, magnesium, manganese, molybdenum, and zinc, is necessary.
Bloom
Flowering begins in early summer and continues throughout the season. Maintaining the correct level of irrigation, lighting, and fertilization ensures excellent flowering for mammillaria cacti.
Uses
Ornamental
Most species of the genus Mammillaria are used as indoor ornamental plants due to their large and attractive flowers.
Among the main species used as ornamentals, the following stand out: Mammillaria senilis , Mammillaria schiedeana dumetorum , Mammillaria surculosa , Mammillaria schwarzii , Mammillaria roseoalba , and Mammillaria tayloriorum.
Medicinal
Certain species of mammillarias contain chemical compounds that provide medicinal properties, such as disinfectants and wound healing. In fact, a milky liquid from the succulent stems is used to disinfect and heal ulcers or wounds.
