Lithops, or also referred to as pebble plants, are succulents that grow extremely slowly and rarely get more than 1-inch above the soil. They usually only have a pair of leaves, which look more like stones than leaves with a fissure separating them (small gap) and epidermal windows (the small holes on top of the leaves)
Light Exposure: Lithops have adapted to tolerate harsh sunlight in their native environment. Thus, the best way to care for them would be to provide 4-5 hours of early sunlight, and partial shade in the afternoon.
Ideal Temperature: Lithops are desert succulents that can tolerate temperatures up to 90 to 100 degrees Fahrenheit.
Water: Since Lithops can store water for months in their leaves, watering this plant at the wrong time in their growth cycle can lead to its demise.
Soil: It is best for Lithops to be planted in cactus mix or fast-draining potting soil. Sand, pebbles, or other gritty materials can also be added to help with soil drainage.
Fertilizing Needs: In general, Lithops don’t require fertilization to thrive.
