Family of cactus. Homeland - the desert regions of Mexico and the southern United States. This genus has about 35 species. Most of the ferocactuses that are widespread in indoor conditions do not bloom, but are valued for the singularity and beauty of the thorns. Ferocactuses also have their own peculiarity - during the period of growth, sweet syrup is released from the center of the rosette of thorns, which hardens, forming sugar crystals. It is recommended to carefully remove or wash off with a brush soaked in alcohol.

Interestingly, young ferocactuses, especially those grown from seeds, are quite unpretentious, but with age they become more demanding and capricious, which makes them difficult to grow and requires more attention.

Distinctive features of various types of ferocactus: deeply cut ribs, rather thick and straight. The spines are very powerful, long, often hooked and brightly colored. Under natural conditions, some old cacti have spines up to 15 cm long. The spines can also be round or flat from the base. Another feature: the areoles, although fluffy, large, on the top of the head they never merge into a fluffy cap, like some other genera of cacti.

  • Wide-spined ferocactus Ferocactus latispinus - stem is spherical, slightly flattened, about 15-23 ribs, with large areoles. Radial spines from 6 to 12, they are white-pink, up to 20 mm long. 2-3 central spines, all directed upwards, only one is different in color - yellowish or reddish, flat, wide and crooked downwards. The flowers are red or purple, the corolla is about 5 cm in diameter.
  • Ferocactus Imary Ferocactus emoryi - the stem is spherical, gradually elongated, becomes cylindrical. Ribs about 22-30, thin with slight tuberosity, white large areoles. Radial spines from 6 to 8, they are white, white-pink, almost red in old cacti, very long on average 4-5, up to 6 cm long. One central spine up to 10 cm long, crocheted at the end. The flowers are red or yellow, 5.5 to 7.5 cm in diameter.
  • Powerful ferocactus Ferocactus robustus - this species branches well in the root zone and forms very wide clumps, colonies. A single plant is small in size, but together they reach several meters in width and up to 1 m in height, forming cactus reefs. The stems are small, dark green in color, often with a reddish-gray tint. Ribs 8, thin, tuberous. Areoles are large, young white, gray with age, almost invisible among the thorns. Radial spines 10-14, subulate, gray-brown. 4-6 central spines, red-brown or horn-colored, straight, square in section, sometimes flattened laterally. The lower central spine is longer, up to 6 cm long, also straight. The flowers are yellow-orange about 4 cm in diameter.
  • Porcupine ferocactus Ferocactus hystrix - young stems are spherical, old ones in nature - barrel-shaped, of low decorative quality. The species has many forms and variations, differing in the number and shape of the thorns. Most of them do not like the bright midday sun in spring and summer, unlike many other ferocactus. They are also susceptible to root rot, to the point that in culture they are most often grown grafted rather than on their own roots.

Ferocactus care

Temperature: Moderate in summer, the more fresh air the better. In winter, a dormant period at a temperature of + 8-10 ° C, at least + 5 ° C, with a dry content.

Lighting: Bright sunlight in both winter and summer for most species. Some species prefer light shading at midday on sunny summer days.

Watering: moderate in spring and summer, after thoroughly drying the soil. From autumn, watering is reduced, and in winter without watering with a cold content. Try to water in such a way that water does not linger on the surface of the soil, for this the neck of the cactus should not be surrounded by soil (earth), but by fragments of upper drainage (pebbles, gravel). If the water is too hard, contains impurities of calcium, iron, then a brown crust may appear on the lower part of the stem, this is not a disease, but try when watering so that the water spreads near the walls of the pot, and not along the trunk and near the neck.

Top dressing: from late spring to mid-summer ferocactus with a special fertilizer for cacti.

Humidity: Ferocactus are resistant to dry air, but regular spraying with warm water is very beneficial.

Transfer: annually in March - April. Soil - 2 parts of turf, 1 part of leaf, 1 part of peat land, 1 part of sand and brick chips. Up to 20% clay is also added to the soil. Young ferocactuses are replanted annually, old ones after a few years. The pH of the soil is about 7-7.2. Ferocactus are sensitive to waterlogging. Therefore, both the lower and upper ones are well drained in the pot, and crumbs of birch charcoal can be added to the soil.

Ferocactuses grow slowly, so frequent transplants and large pots are not needed. The need arises when roots begin to crawl out of the drainage holes.

Reproduction: seeds that sprout easily and are immediately covered with strong thorns. They practically do not propagate vegetatively and by vaccination.

For more information about the features of various modes of maintenance, transplantation and reproduction, see the section Cacti.

Ferocactuses are very sensitive to sudden changes in temperature and drafts. Therefore, they need to be careful to accustom them to fresh air. In winter, if there is a sharp drop in temperature, for example, if a window is opened, cracks and brown crusts appear on the ferocactus on the stem, which disfigure the plant.
