Light Requirements: Lithops thrive in bright, direct sunlight. They need at least 4-5 hours of direct sunlight each day. If grown indoors, place them in the sunniest window available. Insufficient light can cause the plants to become elongated and lose their compact shape.
Watering Needs: Lithops require minimal watering. Water sparingly, allowing the soil to dry out completely between waterings. Typically, water them only once every few weeks during their growing season (spring and fall). Do not water during their dormant period in summer and winter, as overwatering can cause them to rot.
Soil Preference: Use a well-draining, gritty cactus or succulent mix. A mixture of potting soil, sand, and perlite or pumice works well to provide the necessary drainage and prevent water retention.
How to Fertilize: Fertilize sparingly, if at all. Lithops generally do not require fertilization, but if desired, use a diluted, balanced cactus fertilizer at half-strength once a year during the growing season.
Hardiness Zone: Suitable for outdoor cultivation in USDA zones 9-11. In cooler climates, they are best grown indoors or in a greenhouse to protect them from frost and cold temperatures.
Pet Safety: Lithops are non-toxic to cats and dogs, making them safe for households with pets.
Additional Care Tips: Lithops prefer low humidity and thrive in dry conditions. Ensure good air circulation to prevent fungal issues. Do not water during the plant’s dormant periods in summer and winter. Lithops will naturally split and shed their outer leaves as they grow; this is normal and does not require intervention. Repot infrequently, as they prefer to be root-bound and do not need much space. To mimic their natural habitat, provide Lithops with plenty of bright light and minimal water. Allow the old leaves to dry out and shrink naturally; they will eventually be replaced by new leaves from within. Avoid touching or disturbing the plants frequently, as this can stress them.
