Rebution: home care, reproduction, types, photos
Rebutia (lat.Rebutia) - a genus of cacti growing in Argentina, Peru and Bolivia, which, according to various sources, includes from 40 to 100 or more species. Due to their unpretentiousness, small size, readiness to bloom in any conditions and the ability to form a large number of children, these plants are very popular in indoor floriculture.
The rebutia cactus is a close relative of the Ailostera, an equally popular plant of the same family. Both of these cacti are so similar to each other that in 2001 all representatives of the Ailoster genus were introduced into the Rebucian genus. True, among scientists there were also those who did not approve of this "merger", therefore the final decision on whether these two genera were correctly combined into one has not yet been made and continues to cause difficulties.
However, for practicing flower growers, little has changed, since the methods of care and conditions of maintenance for rebuts and ailoster are exactly the same.
Planting and caring for rebution
- Bloom: from the second year of life, under good conditions, it can bloom throughout the year, but the cactus lays flower buds at the end of February.
- Lighting: bright sunlight throughout the year: southern windowsills are most suitable.
- Temperature: during the growing season - common for living quarters, but in winter a cooler content is needed - 8-12 ºC.
- Watering: regular and even: in the summer - once a week, but in extreme heat, the substrate will have to be moistened more often. In winter, watering is almost completely stopped, especially if you are interested in the appearance of children.
- Air humidity: usual.
- Top dressing: from April to September - once a month with complex fertilizer for cacti. The nutrient solution is added to a pre-moistened substrate.
- Rest period: not pronounced, but usually within 1-1.5 months after flowering.
- Transfer: in March, as necessary, when the roots will master the earthy lump.
- Reproduction: sometimes by seeds, but more often and easier - by lateral shoots (children).
- Pests: sometimes affected by red spider mites, scale insects and mealybugs.
- Diseases: stem rot and cork growths.

Rebucias have perfectly spherical ribbed stems covered with a large number of spines. These plants reach a height of 5-6 cm, but sometimes they can grow up to 10 cm. The ribs on the stems of the rebuts are low, weakly expressed, arranged in a spiral and divided into tubercles. There are at least 11 ribs on the stem. Each areola can have up to 30 heterogeneous, thin, bristle-like spines: radial - up to 5 mm long and central - up to 3 cm in length. Due to the abundance of thorns, rebutia cacti look like fluffy balls. Sufficiently large single, glossy, funnel-shaped, wide-open flowers of orange, yellow-orange, red or orange-pink hue are usually formed in the lower areoles of the lateral surface of the stem, forming a girdle wreath. It is possible to distinguish an ailoster from a rebutia by the structure of the flower: if you look closely, the pistil of the ailostera half grows together with the pubescent tube, and the rebutia has a smooth and non-accrete tube.
Rebution care at home
Caring for rebutia at home does not involve any difficulties, since these are mountain plants that require a minimum of comfort. The most important thing in growing a cactus is to provide it with a cool content (8-12 ºC) during wintering, otherwise the plant will refuse to bloom in the future. When buying a cactus, do not forget to check with the seller what the optimal temperature for your rebution should be, because recently bred varieties have been recommended wintering at 5 ºC, and frequent airing of the room is also a prerequisite: rebutions do not tolerate stale air and are very fond of changes between daytime and nighttime temperatures. As for the period of active growth, at this time the rebuts put up with any temperature regime.
Rebuts are very photophilous and are not at all afraid of direct sunlight, so you can safely place them in the sun and not worry that the plants will overheat or get burned. But the easiest shading of the rebution will not work.
Rebution normally tolerates infrequent waterlogging of the substrate, but try not to abuse it. Watering should be uniform and sufficient, and their frequency depends on the evaporation of moisture from the soil and the temperature in the room. In the summer, one watering a week may be enough, but if there is an abnormal heat, then you can water the rebutia more often. The frequency of watering in winter is determined by the same conditions: the temperature in the room, which is much lower than in summer, and the degree of evaporation of moisture from the soil, which is also at a low level in winter. Consequently, rebutia is rarely watered during the dormant period, and the rate of water consumption is also significantly reduced. If the plant hibernates in a warm room or grows children whose diameter does not exceed 3 cm, its watering should also be scarce and rare. However, keep in mind that the transition from summer to winter watering and vice versa should be gradual.
Water the rebution with water that has been settled during the day, the temperature of which should be a couple of degrees higher than the temperature in the room.
You do not need to spray or wash the cacti. Dust from plants is swept away with a soft brush.
You can not fertilize the rebution at all, however, once a month from April to September, feeding with a non-concentrated solution of special complexes for cacti will help you achieve a lush flowering from the rebution. Solutions should be applied only on a moistened substrate.

Rebuts are transplanted in March, at the very beginning of the season, and only when their roots have completely mastered the substrate in the pot. For these plants, a special soil for cacti or succulents is most suitable - light, permeable, based on sand and containing gravel. Do not water the substrate in an old cactus pot before replanting: the soil must be completely dry. Place a thick layer of drainage material on the bottom of the new pot, transfer the rebution from the old pot to the new one, and fill in the remaining space. dry soil mixture. Place the plant in a warm and very bright place. The first watering of rebutia after transplantation is carried out only after a week. And in the next 2-3 months, also be very careful with moisturizing.
The flowering of rebucias, like ailoster, begins in the second or third year of life and usually occurs in summer. Flowers open only in clear weather, closing at night. Each flower lives for at least two days.
If, despite your efforts, the rebutia does not bloom, check if all the necessary conditions are met:
- the plant needs a lot of bright sunlight;
- in winter, the flower should be kept at a temperature not exceeding 10 ºC;
- the substrate for rebution must be well-drained;
- in summer, the plant is watered moderately, infrequently in autumn, and in winter it is better not to water at all.
Reproduction of rebutia
The rebutia flower constantly grows and bushes, so it is easy to propagate it vegetatively: you just need to separate the side shoots and plant them for rooting in a light, loose substrate. Such babies grow very quickly and soon they themselves begin to give birth to offspring.
You can grow rebutia from seeds, which are first disinfected for 10 minutes in a weak solution of potassium permanganate, and then dried in the fresh air. Sowing is carried out in early March in wide low bowls filled with a mixture of a substrate with sand or a substrate with stone granules. The seeds are spread at a distance of 2-3 cm from each other: with such a density of sowing, the seedlings can not be dived in the future. Young rebuts are grown at a temperature of 15-20 ºC, regularly ventilating, spraying or watering the substrate. Slightly grown seedlings are planted in separate pots. The rebutia needs good lighting all year round, so on short winter days you will have to supplement the seedlings for the first two years.
Pests and diseases
Diseases and how to treat them
Sometimes cork formations appear on the rebution. This happens as a result of mechanical damage to the stem, hypothermia or insufficient watering in the summer. And if you water the plant during dormancy, when it is in a cool room, it may develop stem rot. If this happens, you need to stop watering and let the stem dry out. Nitrogen fertilizers applied at the wrong time or in too much amount can lead to decay of the root system of the rebution. Try to follow our recommendations, and your cactus will never get sick.

Pests and the fight against them
Rebutia, which is quite resistant to diseases and pests, is sometimes affected by red spider mites, scale insects or mealybugs. The scale insects and worms must be removed from the plant with a cotton swab dipped in alcohol, after which the rebution should be treated with Actellik or Fitoverma solution. The same drugs are also used against ticks. As a preventive measure, inspect the rebution as often as possible and wipe it with a brush moistened with alcohol.
Types and varieties
Most often, rebuts with abundant and bright flowering are grown in room culture.
Or minuscule rebution - a very beautiful miniature plant, a spherical, flattened stem of which reaches 5 cm in diameter. The tubercles on its ribs are arranged in a spiral, and white spines stick out from the areoles in an amount of up to 30 pieces. Flowers in plants of this species are large, bright red or crimson, and after flowering, small reddish berries are formed on the plant.

Home cacti (90 photos): types, care and watering
Almost everyone who asks questions about beautiful and unpretentious home plants, one way or another, comes to the idea of having a cactus. They are loved for their variety and unusual appearance. There are many myths, beliefs and signs around them. It is believed, for example, that if a cactus suddenly bloomed - this is an important joyful event. Finally, this is a real find for those who dream of a green home corner, but they are sorely lacking time for complex and regular care.
Caring for the clivia plant at home
Clivia needs different temperatures depending on the season. 20-25 ° C in spring and summer, and during the flowering period should be above 20 degrees. From October 12-14 ° C to allow the plant to rest. An increase in temperature can lead to impaired development of clivia. Libya does not need a lot of moisture: moderate watering is enough. It should be watered as the earth dries.
It is important that water does not remain in the sump when watering. In the autumn-winter period, when clivia is at rest, watering can be excluded. And only if the plant begins to lose leaves, you need to periodically moisten the soil. During the period of the appearance of the pedicel, the flower should be watered more often.
Humidity doesn't matter. It is necessary to spray or wipe the sheets only at the peak of flowering or heat.
You need to feed the clivia in spring and summer. The ideal option would be to alternate between organic and mineral fertilizers.
With proper care and regular rest, clivia blooms every spring.In order for the plant to delight with flowers every year, it is necessary to give the clivia a rest for 2 months for young plants, more for adults. As mentioned above, it is better not to water the clivia at all without special need during the dormant period.
The pot with clivia, the length of the peduncle of which has reached 10 cm, is transferred to a warm place. At the same time, it is important to be careful: clivia do not like to be disturbed. When moving, it is also worth considering the direction of growth of the leaves of the plant. Otherwise, the leaves will begin to fall off.
Currently, botanists have described 17 species of radermacher. Among them are:
However, despite all the species diversity of the plant, only one species is grown as an indoor plant - the Chinese Radermachera (Radermachera chinensis). Its distinctive feature is large glossy leaves, reaching 70 cm in length and 25 cm in width. The leaf blade is divided into several small segments up to 4 cm long.
