Light
Lithops thrive in bright light and prefer several hours of direct sunlight each day. A south- or west-facing window is ideal. If grown indoors, make sure they receive strong, consistent light to maintain their compact shape and vibrant color. Too little light can cause them to stretch or lose their distinct stone-like appearance.
Water
Proper watering is the most important part of Lithops care. These succulents store water in their thick leaves and require very little moisture. During their active growing season (spring and fall), water only when the soil is completely dry—typically once every 3–4 weeks. Stop watering entirely during the summer and winter dormancy periods, as excess water can cause the plant to split or rot.
Soil
Use a very well-draining cactus or succulent mix with extra perlite, pumice, or coarse sand. Lithops grow best in gritty soil that dries quickly. Avoid soils that retain moisture.
Temperature and Humidity
Lithops prefer warm, dry conditions and grow best in temperatures between 65 and 85 degrees Fahrenheit. They can tolerate cooler nighttime temperatures but should be protected from frost. These plants do not require additional humidity and thrive in dry indoor air.
Fertilizer
Fertilization is rarely needed. If desired, feed sparingly with a diluted, low-nitrogen succulent fertilizer once a year during the growing season. Over-fertilizing can damage the plant or alter its natural growth pattern.
