How to care for the plant Sempervivum
The web tells you about the knowledge of the succulent plant Sempervivum, how to care for it, let's take a look together!
Sempervivum is native to the desert areas of central Mexico and the southern United States, preferring warm, dry, and sunny environments, fearing waterlogging, drought-resistant and semi-shady, requiring a significant day-night temperature difference, mainly growing in spring and autumn, watering should follow the principle of "no watering when not dry, and watering thoroughly when watering", to avoid waterlogging in the potting soil, otherwise it will cause the fleshy roots to rot. Although the plant will not die in a long-term dry environment, growth is slow or even stagnant, the epidermis becomes wrinkled and loses its luster.
Sempervivum prefers a humid environment, and a higher humidity should be maintained during cultivation. Some enthusiasts use transparent, colorless beverage bottles to cover the globular part for care, which although makes the globular part plump and the epidermis clean and lustrous, it is also prone to rust disease due to poor air circulation, and can be regularly sprayed with fungicides such as carbendazim and propiconazole for prevention.
During the growing period, apply a thin organic liquid fertilizer or a "low nitrogen, high phosphorus and potassium" compound fertilizer once a month, and avoid splashing fertilizer water on the globular part.
In the hot summer, the plant grows slowly but not completely stops, requiring good ventilation and avoiding a stuffy and dry environment, otherwise it is easily infested by red spiders. Stuffy and humid conditions can lead to rust or stem rot disease, so ventilation must be good in summer, and appropriate shading should be done to prevent strong direct sunlight from burning the globular part.
In winter, place the plant in a sunny indoor area with a minimum night temperature of about 10°C and some day-night temperature difference, and water normally to allow the plant to continue growing. If such high temperatures cannot be maintained, water should be controlled to make the plant dormant, and it can safely overwinter at about 5°C.
For the vigorous Sempervivum, repot once a year in April, the potting soil should be loose and fertile, with good drainage and aeration, containing some granularity and an appropriate amount of lime. A mixture of 2 parts of deciduous leaf soil or peat soil, 3 parts of coarse sand, and the addition of a small amount of bone meal, shell powder, and lime-based planting material can be used. Some people also mix a small amount of slow-release compound fertilizer into artificial materials like red jade soil and orchid stone, and the effect is also good. Due to its fleshy roots, a deeper pot should be used for planting, and more tiles or coarse gravel should be placed at the bottom of the pot to aid drainage.
