Environmental conditions

Light. It is a light-loving species, and for a harmonious growth and development, young specimens in particular need to be exposed to indirect light. However, both mature and young plants should benefit daily from at least 4-6 hours of indirect light.

temperature

Temperature. Crassula ovata prefers temperatures between 18-21 °C. In winter, the optimum temperature is 10-12 °C during the day and 7-9 °C at night. In summer, it can withstand temperatures of 29-30 °C.

Substrate. It is recommended to use a special substrate for succulent plants, which ensures the good drainage of water and thus prevents excessive moisture, persistent in the substrate, which can cause the occurrence of soil pathogens.

Care

Watering. During the vegetative growth period (spring-summer) watering should be done moderately, allow the substrate to dry before watering again. Also, after each watering, the surplus that accumulates in the tray needs to be removed every time, because the stagnation of the water can lead to the suffocation of the roots and the occurrence of diseases.

Fertilization. During the vegetative growth period, it is recommended to administer fertilizers specially formulated for succulent plants.

Propagation by stem cuttings. It is done with cuttings harvested from mature, healthy plants. The seedlings are harvested when they are at least 5-7 cm long, then left to dry for a few days. Subsequently, after the respective part has dried, they will be planted in a substrate specially designed for this purpose.

Propagation by leaf cuttings. It is done with cuttings harvested from mature, healthy plants. The process consists in removing (with a slight twist) / cutting a leaf (with a small portion of the stem), which is then rooted (after the section has dried) in a substrate specially designed for this purpose.

Transplanting. Normally, it can be done once every 2-3 years in the case of young plants and once every 4-5 years in the case of mature specimens.

Diseases and pests. Due to high humidity, persistent in the substrate, various soil pathogens can occur. The most common pests that can attack Crassula ovata are wooly apple aphids, but it can also be affected by European fruit lecanium or red spider mites. To control diseases and pests, it is recommended to carry out treatments with specific products, depending on the pathogen / pest targeted.

Common problems that may occur

Leaf fall

If this phenomenon has a high frequency, it could occur due to the fact that the plant does not receive enough light. In this sense, it is recommended that the plant be placed in a brighter place, where it benefits from at least 6 hours of indirect light per day. At the same time, it is recommended to follow the evolution of the plant after taking this measure, in order to be able to observe if the phenomenon is accentuated or if it stops.

Additionally, if most of the falling leaves are old or if the loss of leaves is accompanied by an etiolated growth of the plant, the temperature in that room may be too high, therefore, it is recommended to move it to a room with slightly lower temperatures.

Withering of the leaves

Crassula ovata is a succulent plant, and the main characteristic of succulents is to store water in thickened organs (leaves, stems, even roots). Thus, if the leaves or the whole plant has a withered appearance, it is often a sign that it is not receiving enough water, and after proper watering, the general state of the plant should improve.

The overall yellowing of the plant

It often occurs in case of excessive watering, therefore, it is recommended that watering be done moderately, leaving the substrate to dry before watering again, according to the requirements of the species.

The information on the various problems that may arise is indicative and can often be the result of a much greater accumulation of biotic and abiotic factors. Therefore, when the first symptoms appear, it is advisable to consult a specialist for a suitable recommendation.

Additionally:
  • Direct sunlight can cause burns to young plants and reddening of the leaves, in the case of mature plants;
  • It is a toxic plant for dogs and cats.
