Lithops
Lithops , often called rock plants or stone plants , are succulents native to the arid regions of South Africa. Their unique appearance, which mimics rocks or stones, is an adaptation to blend into their environment and evade predators. Each plant is composed of two fleshy, fused, dome-shaped leaves that form a compact structure. Lithops range in color from gray to brown to green, often with patterns and marbling that give them a natural appearance.
In autumn, these little wonders produce pretty white or yellow, daisy-like flowers that emerge from the centre of the leaves.
Lithops Care
Light : Lithops need plenty of direct light to thrive. Place them in a location where they can get several hours of sunlight per day, such as a well-exposed window. They will also tolerate strong artificial light if natural exposure is lacking.
Watering : Lithops are succulents that require very little water. Water sparingly, and only when the soil is completely dry, which can mean every 2 to 3 weeks in the summer. In the winter, during their resting period, avoid watering altogether , as excess moisture can cause root or leaf rot. A simple rule is to never let water stagnate in the pot.
Humidity : They prefer a dry environment and do not need additional humidity. An environment that is too humid can be detrimental to their health, especially in low light conditions.
Temperature : Lithops thrive in warm temperatures, around 20 to 30°C. They tolerate high temperatures well, but should be protected from frost or temperatures below 10°C.
Substrate : A very well-draining substrate is essential for Lithops. Use a specific mix for cacti and succulents, or prepare a homemade mix composed of light potting soil, coarse sand and gravel. Drainage must be optimal to avoid water retention.
Fertilization : Lithops do not need a lot of nutrients. A diluted fertilizer, specifically designed for cacti and succulents, can be applied once a year in spring or early summer. Avoid over-fertilizing, as this can hinder their growth.
Repotting : Lithops do not need to be repotted often, as they like to be cramped in their pot. If necessary, repot them every 3 to 4 years in the spring, in a pot with excellent drainage.
Life Cycle : Lithops replace their leaves every year. A new pair of leaves grows inside the old ones, and eventually the old ones dry out and disappear. During this time, it is crucial not to water , as the new leaves use the water reserves of the old ones to grow.
Propagation : Lithops can be propagated by seed, but this requires patience, as germination can take several months and the plant takes years to reach its adult size. They can also be propagated by division if several plants form from a single one.
Toxicity : Lithops are non-toxic, making them safe plants to grow in homes with pets or children.
Lithops are fascinating plants that are easy to care for succulent lovers, as long as you respect their specific light and watering needs. Their unique appearance and low water requirements make them ideal for those who love plants but sometimes forget to water.
