Care at home
Temperature conditions
These plants do not like the cold, so year-round maintenance at room temperature is suitable. Carallums can withstand brief temperature drops of up to 5°C if kept dry. Winter maintenance at a temperature of 10 - 15° C.
Lighting
Shade the succulent during hot daytime hours in spring and summer. Provide the most illuminated location in autumn and winter.
Substrate
The root system is compact, with a large number of small roots, so loose soil is used for growing, for example, ready-made mixtures for cacti and succulents with the addition of coarse river sand, perlite or pumice to improve drainage.
Feeding
Caralluma is fed with fertilizers for cacti and succulents with a high potassium content and low in nitrogen, 2 times a month in half the concentration.
Purpose
A very unusual, spectacular, compact plant.
Flowering time
End of summer - autumn.
Air humidity
No need to spray. In winter, the air should remain dry. It is advisable to ensure good air movement around the carallum, while avoiding cold drafts.
Soil moisture
Water moderately but deeply during the growing season, allowing the soil to dry out before the next watering. Reduce watering in winter so that the earthen ball does not dry out.
Transplant
Adult specimens are replanted every 2 years, in the spring, it is advisable to use clay pots, the walls of which allow air and water to pass through and allow the soil to dry out faster.
Reproduction
Propagated by stem cuttings in spring and summer. Pre-dry the cut site for 1 - 2 days. Sowing seeds in spring in a damp mixture of peat and sand. Seeds germinate quickly. Grafting.
Pests and diseases
Plants are very sensitive to stem and root rot, which appear as a result of waterlogging, especially in the autumn-winter period. Sometimes mealybugs or scale insects appear.
Varieties:
Caralluma fimbriata
Small evergreen succulents up to 20 cm high with thick, tetrahedral stems branching at the base, reminiscent of a cactus. Small, rudimentary leaves sometimes appear on young plants, but they fall off with age. During the flowering period, few-flowered inflorescences appear at the tops of the shoots, which bear small flowers up to 2 cm in diameter.
