Rebutia solar

  • Tiny rebutia (minuscula) Rebutia minuscula - with a spherical light green stem, flattened on top, about 5 cm in diameter. Ribs 16-20, with small but well-defined tubercles. Each areola has up to 30 whitish thin spines, 2-3 mm long. There is no central thorn. The flower is bright red, about 4 cm in diameter and 4 cm in tube length. Flowers appear closer to the base of the stem.
    • Variations of the Rebutia of the tiny (minuscule) Rebutia minuscula - represented by the variety of the former Rebutia senile (senilis) Rebutia senilis - now it is not a separate species, but a kind of miniscule. Moreover, within a species, variations are very different, for example: var. schieliana has up to 15 whitish spines with brown tips and orange-red flowers; var. sieperdaiana has pink-yellow flowers about 3.5 cm in diameter.
    • Rebutia is a tiny variation of Wessner's Rebutia minuscula var. wessneriana - has a longer cylindrical stem, its diameter is about 8 cm, height is up to 7 cm and the color is more saturated green. Whitish (or gray) radial spines up to 20, up to 15-20 mm long. The central spines are not pronounced. The flowers are red, about 5 cm in diameter of the corolla.
  • Rebutia Marsoneri Rebutia marsoneri - about 4 cm high, 4 cm in diameter, has a light green stem, on which large areoles (much more noticeable than other rebucias). Radial spines are whitish, there are about 8-12 of them, but short, only 1-2 mm. There are no central spines. The tube of the flower is about 3 cm long, the corolla is blood-red, about 4 cm in diameter. The synonym is Rebutia Krainz Rebutia krainziana.
  • Rebutia solar Rebutia heliosa is a completely unusual in shape and beauty rebutia, characterized by the fact that its stems are strongly branching, form incredible growths, similar to corals. Each cactus stem is spherical, about 2.5-3 cm in diameter. Many ribs - about 35-40, small oval halos up to 1 mm. There are 24-26 radial spines, they are silvery, no more than 1 mm, almost completely hide the stem itself. There are no central spines. It blooms with bright orange or orange-red flowers about 4 cm in diameter and 5 cm long.
  • Rebutia pulvinosa Rebutia pulvinosa - This small rebutia has good bushiness. The stem is cylindrical, about 5 cm long and 3 cm wide. Covered with white thin spines, like hairs - total of 5 to 22 radial spines, rather flexible, 3-5 mm long. There are also 6 central spines - these are more authentic, up to 1 cm and pale brown in color. Flowers are orange-yellow 2-3 cm in diameter. There is a form with white flowers. Synonym - White-flowered Rebutia albiflora.

Many types of rebutia are currently referred to as other genera. So, Lobivia Lobivia pygmaea is the former Rebutia pygmaea ssp. violascens; Lobivia pygmaea - Rebutia pygmaea; Lobivia einsteinii - Rebutia einsteinii etc.

Rebutia is tiny

A native of Bolivia, rebutia grows in semi-arid regions at an altitude of about 2500 m above sea level, on sedimentary rocks. The climate here is characterized by dry winters, with an average temperature of about + 10 ° C, and rather rainy summers. Therefore, at home growing cacti should strive for the ideal - fresh air and cold winters. Although rebutia is considered one of the simplest species, and generally undemanding to care for, it blooms easily and forms berries with numerous seeds.

Temperature

Moderate all year round, does not like the rebution of the scorching sun, when the heat on the southern windows is above 40 ° C and there is no air movement, in greenhouse conditions the cactus will suffocate. Therefore, do not keep plants on a stuffy closed balcony, open windows or vents. Winter minimum at an average temperature of + 10 ° С (minimum + 5 ° С), with absolutely dry content, it is advisable to withstand at least 2-3 months.

Lighting

Bright, intense lighting with direct sunlight. After winter, accustom to the bright sun gradually, in species with short thorns, burns are possible. Rebuts love a lot of light in winter and summer.

Watering

Moderate in spring and summer, after the soil has dried, keep the cacti dry for several days. The most dangerous period is the rainy season in central Russia from mid-August - be careful, the soil dries longer, reduce watering, and stop completely by the time of cold wintering. In winter, they practically do not water, and if the temperature is warmer, within 18-14 ° C, watering is rather rare and stingy, literally with a teaspoon.

Fertilizer

If necessary, from late spring to mid-summer, they are fed with a special fertilizer for cacti, diluted according to the instructions. With fertilizers, the usual rule is, if in doubt, do not feed.

Air humidity

Rebuces are resistant to dry air, like all other cacti, but respond well to spraying the air around them in spring and summer from a very fine spray bottle in the morning.

Transfer

Rebuts are transplanted annually or as needed, when the roots grow too much, or the colony of cacti (along with the children) begins to fall out of the pot, but at least once every two years. Soil for rebuts: 1 part of sod land, 1 part of leafy soil and 1 part of granite chips, a few grains of charcoal per pot (1/8 of the total volume of soil). Since most rebucias branch well, the pot for them should be wide, but not deep, and at the bottom there are large holes for water drainage. Young plants are transplanted annually, old in a year.

Flowering rebutia

Rebution is prized for the beauty of the thorns and for its tremendous responsiveness and grateful flowering, if its care meets the needs of the cactus. And there are few conditions:

  • sun during the warm season: south window without shading from the street by trees or houses
  • cold wintering from November to February: the natural deterioration of illumination when the temperature drops to 5-10 ° С is not significant
  • watering in the warm season with visible growth is frequent, when planting in small pots in the correct drained soil - abundant, until the soil is completely wetted
  • watering in cold weather is very rare, the soil is almost always dry
  • top dressing has practically no value for flowering

Personal observations, Natali:

While the temperature is not higher than 10 ° С, already at 12 ° С in cloudy weather, chalked vegetation begins, the cactus stems tend to the light, at temperatures above 15 ° С - a noticeable elongation of the tops.

Rebutia Rebutia heliosa v. condorensis were planted in September 2013, grown in a mixture of leafy soil and zeolite granules (in equal parts) with top drainage. Grown on the southern balcony in summer, from September on the northern balcony (glazed, not insulated) until the end of October. The first two winters are supplemented in winter from October to February - they love a lot of light.

In the third year, I divided all the cactus cubs into two parties. When the temperature on the balcony approached + 4 ° C, I left one batch of three-year-old seedlings in the room (plastic window), fenced it off from the edge of the window sill with glass, but this was not enough, the temperature kept around 18 ° C and a good rest period did not work out. The second batch was put up on the window sill on the landing, until March. The temperature was just the same (the frames were wooden, the barrel was blowing, but the pots were in a plastic container) from +8 to 12 ° C, not higher. Watering about once a month with a moderate amount of water (only the top layer of soil was moistened to the middle of the pots).

The first batch was slowly drawn out. The second batch of rebuts was brought in as soon as the temperature on the southern balcony in the spring was at least + 4 ° С. In mid-spring, shaggy pimples appeared between the thorns, grew slowly, for the first time I saw the rudiments of peduncles at the end of April, they began to look like buds at the end of May, blossomed in early June.

There were no buds on non-wintering rebuts, and from 5 to 8 buds on overwintered ones, opening in turn. The seedlings were fed only in the first two years three times: in the spring, in the middle and at the end of summer).

Reproduction

Seeds and cuttings (offspring). Sow the seeds in wide bowls, in rows at a distance of at least 2 cm from each other, in a mixture of sand and peat soil. Germination and development at a temperature of 24-26 ° C. Be careful with watering, seedlings are sensitive to waterlogging. Young plants begin to bloom in the second or third year of life.

Many rebucias branch quite strongly, and if other cacti have babies that easily fall off and take root, then in rebucias the lateral shoots seem to become an independent cactus, but are nevertheless connected to the mother plant by a thin isthmus, form dense, but strong colonies. If desired, they can be separated and seated separately. Most likely, this even needs to be done when, branching and expanding, the shoots begin to oppress each other.

There are great difficulties in collecting rebuts. The fact is that, due to the ease of reproduction and undemanding cultivation, many hybrid forms have appeared among rebucias, and it is sometimes very difficult to determine which species a given rebutia belongs to by appearance. Therefore, for those who want to collect real rebuces, and not their little similar hybrids, it is better to purchase seeds in specialized stores or subscribe from a catalog.

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

Growing problems

The main problem with growing rebuts is tick damage. This frequent pest can disfigure and destroy unpretentious cacti in a short time. As a preventive measure, regularly inspect the plants, if you suspect, wipe the rebutions with a brush dipped in medical alcohol, and at the first signs of a pest - a silvery film or plaque on the stem, treat with acaricides.

The second problem is over-watering. Rebuces are very susceptible to root rot, so the soil for them must necessarily contain gravel or granite chips - these components do not allow the soil to compact and retain water for a long time. Never bury the root collar in the substrate with the rebuts - only the upper drainage from the pebbles should fix the body of the cactus.

In the spring, in the bright sun, the cactus stalks can turn red out of habit - you just need to shade it with a mosquito net in the first sunny week, in general, rebuts are very photophilous.
