Everything it needs
9 essentials at a glance
Watering
Lithops lesliei requires very little water, typically needing to be watered every 2-3 weeks during the growing season (spring and summer).
Allow the soil to dry out completely between waterings to prevent root rot. In the fall and winter, reduce watering to once a month or less. Signs of over-watering include mushy leaves and a foul smell, while under-watering may cause the leaves to shrivel and become wrinkled.
Light
Lithops lesliei thrives in bright, indirect light but can tolerate some direct sunlight.
Ideally, it should receive about 4-6 hours of light daily. A south or east-facing window is perfect for placement. Too much direct sun can scorch the leaves, while too little light may cause etiolation.
Soil
This plant prefers a well-draining soil mix, ideally a cactus or succulent mix with added perlite or sand to enhance drainage.
The pH should be slightly acidic to neutral, around 6.0 to 7.0. Ensure the pot has drainage holes to prevent water accumulation.
Humidity
Lithops lesliei prefers low humidity levels, ideally below 40%.
To increase humidity, you can mist the plant lightly or place a humidity tray nearby, but avoid excessive moisture. Signs of humidity stress include wrinkled leaves and poor growth.
Temperature
The ideal temperature range for Lithops lesliei is between 65-80°F (18-27°C) during the day and slightly cooler at night.
It is hardy in USDA zones 10-11. Protect the plant from temperatures below 50°F (10°C) as it can suffer damage from cold.
Fertilizing
Use a diluted cactus fertilizer with an NPK ratio of 5-10-10 during the growing season, applying every 4-6 weeks.
Do not fertilize in the fall and winter. Signs of nutrient deficiency include stunted growth and pale leaves.
Pruning
Lithops lesliei generally does not require pruning.
However, if dead leaves appear, they can be gently removed at the base to maintain appearance. Use clean, sharp scissors to avoid damaging the plant.
Repotting
Repot Lithops lesliei every 2-3 years or when it outgrows its pot.
Choose a pot that is only slightly larger than the current one. Signs it needs repotting include roots growing out of the drainage holes or soil that dries out too quickly. To repot, carefully remove the plant, shake off excess soil, and place it in fresh soil.
Propagation
Propagation can be done through leaf cuttings or seeds.
For leaf cuttings, take a healthy leaf, let it callous for a few days, then plant it in well-draining soil. For seeds, sow them in spring on the surface of the soil and keep them moist until germination. The best time for propagation is during the growing season.

Care through the year
Spring
In spring, resume regular watering as the plant enters its active growth phase. Fertilize every 4-6 weeks with a diluted cactus fertilizer.
Summer
Continue to water every 2-3 weeks, ensuring the soil dries out completely. Monitor for pests and provide bright, indirect light.
Fall
Reduce watering frequency as the plant prepares for dormancy. Fertilizing should stop as the plant enters its resting phase.
Winter
Water sparingly, about once a month, and keep the plant in a cool, dry location. Avoid fertilizing during this time.
