Lithops salicola
Lithops salicola
Lithops salicola, commonly known as living stones, is a fascinating succulent native to southern Africa. Its unique appearance mimics stones, making it a popular choice for collectors and succulent enthusiasts alike.
Everything it needs
9 essentials at a glance
Watering
Lithops salicola requires very little water, typically only once every 2-4 weeks during the growing season (spring and summer).
Water sparingly, allowing the soil to dry out completely between waterings. In fall and winter, reduce watering to once every 4-6 weeks. Signs of over-watering include mushy leaves and root rot, while under-watering will cause the leaves to shrivel and become wrinkled.
Light
Lithops salicola thrives in full sun, requiring at least 6 hours of direct sunlight daily.
Ideal placement is on a south or west-facing windowsill. While it can tolerate some partial shade, too little light will lead to etiolation, where the plant stretches towards the light.
Soil
The ideal soil composition for Lithops salicola is a well-draining cactus mix or a blend of potting soil, sand, and perlite (2:1:1 ratio).
The pH range should be between 6.0 and 7.0. Ensure the pot has drainage holes to prevent water retention, which can lead to root rot.
Humidity
Lithops salicola prefers low humidity levels, ideally below 40%.
To increase humidity, place a humidity tray with water near the plant, but avoid direct contact with the leaves. Signs of humidity stress include wrinkled leaves or stunted growth.
Temperature
The ideal temperature range for Lithops salicola is between 65-80°F (18-27°C) during the day and slightly cooler at night.
This plant is hardy in USDA zones 10-11. It can tolerate brief periods of heat but should be protected from frost and extreme cold.
Fertilizing
Use a diluted cactus fertilizer with an NPK ratio of 5-10-10 during the growing season, applying every 4-6 weeks.
Avoid fertilizing in fall and winter. Signs of nutrient deficiency include slow growth and pale coloration.
Pruning
Lithops salicola does not require regular pruning, but dead leaves can be removed to maintain appearance.
Use clean, sharp scissors to cut away dead foliage at the base. Avoid cutting live leaves as they are essential for photosynthesis.
Repotting
Repot Lithops salicola every 2-3 years or when it outgrows its pot.
Choose a pot that is slightly larger than the current one, ensuring it has drainage holes. Signs it needs repotting include roots growing out of the drainage holes or soil that dries out too quickly. Gently remove the plant from its pot, shake off excess soil, and place it in the new pot with fresh soil.
Propagation
Lithops salicola can be propagated through seed or division.
For seed propagation, sow seeds in a well-draining mix and keep them moist until germination occurs, which can take several weeks. Division is best done when the plant has formed clumps, carefully separating the offsets in spring. Ensure that all cut surfaces dry out before replanting.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or insufficient light.
How to fix it
Reduce watering frequency and ensure the plant receives adequate sunlight.
Shriveling leaves
Why it happens
Under-watering or low humidity.
How to fix it
Increase watering frequency and maintain low humidity levels.
Mold on soil surface
Why it happens
Excess moisture and poor air circulation.
How to fix it
Allow the soil to dry out completely and improve air circulation around the plant.
Etiolated growth
Why it happens
Insufficient light.
How to fix it
Move the plant to a brighter location with more direct sunlight.
Root rot
Why it happens
Over-watering and poor drainage.
How to fix it
Remove the plant from the pot, trim away any rotten roots, and repot in fresh, dry soil.
Care through the year
Spring
In spring, resume regular watering as the plant begins its active growth phase. Fertilize every 4-6 weeks with a diluted cactus fertilizer.
Summer
During summer, ensure the plant receives plenty of sunlight and continue with regular watering. Monitor for signs of heat stress.
Fall
In fall, gradually reduce watering as the plant prepares for dormancy. Stop fertilizing and allow the soil to dry out more between waterings.
Winter
In winter, limit watering to once every 4-6 weeks and keep the plant in a cool, dry location to prevent rot.
Toxicity & Safety
Lithops salicola is non-toxic to pets and children. However, ingestion of any plant material may cause mild gastrointestinal upset.
