## Succulents Grow Lithops: A Comprehensive Guide to Cultivating Living Stones
Lithops, also known as “living stones,” are captivating succulents that have intrigued plant enthusiasts due to their unique appearance resembling small stones. Growing these enigmatic plants can be rewarding yet requires specific care and conditions to achieve optimal growth.
Understanding Lithops
Lithops are native to the arid regions of southern Africa. They have adapted to survive in harsh conditions, exhibiting unique characteristics:
Stone-Like Appearance: Lithops have two fleshy, bean-shaped leaves that mimic the surrounding rocks, providing camouflage from predators.
Splitting Habit: During the growing season, Lithops undergo a process called “splitting.” A new set of leaves emerges from the center of the existing pair, eventually forming a cluster of several leaf pairs.
Cultivating Lithops
Soil:
Well-Draining: Lithops require a well-draining soil mix to prevent rot. Use a commercial succulent potting mix or create your own blend using ingredients like cactus soil, pumice, and perlite.
Gritty Material: Adding pebbles or sand to the soil improves drainage by allowing excess water to pass through quickly.
Light:
- Bright Sunlight: Lithops thrive in bright sunlight. Provide at least 6 hours of direct sunlight daily.
Water:
Sparingly: During the growing season (spring and fall), water Lithops sparingly when the soil has completely dried out.
Dormancy: Lithops have a summer dormancy period during which they should not be watered at all.
Additional Care Tips:
Fertilizer: Fertilize Lithops once a year during the growing season with a balanced succulent fertilizer.
Repotting: Repot Lithops every 2-3 years, or when the roots become pot-bound. Use a slightly larger pot with fresh, well-draining potting mix.
Troubleshooting
Overwatering: Avoid overwatering, as it can lead to root rot. Allow the soil to dry out completely before watering again.
Sunburn: Protect Lithops from prolonged exposure to intense sunlight, especially during the hottest hours of the day.
Pests: Aphids and mealybugs can infest Lithops. Treat infestations with insecticidal soap or neem oil.
With proper care and attention, succulents grow lithops can thrive and add a unique and captivating element to your succulent collection.

Choose the Right Soil
When cultivating Lithops, selecting the appropriate soil is crucial to their well-being. The ideal soil for these fascinating succulents possesses specific characteristics that ensure optimal growth and prevent potential issues.
Key Takeaways:
- Soil pH: Lithops prefer a slightly alkaline soil with a pH range of 6.5 to 8.5.
- Drainage: Free-draining soil is essential to prevent waterlogging, which can lead to root rot.
- Porosity: A porous soil provides proper aeration for the roots to thrive.
- Avoid Peat: Peat-based soil is unsuitable for Lithops as it retains too much moisture.
Soil Composition
The ideal soil composition for Lithops includes the following:
- Mineral Grit: Perlite, pumice, or crushed granite provide porosity and drainage.
- Organic Material: A small amount (less than 10%) of organic matter, such as composted bark or worm castings, can provide some nutrients and improve water retention.
- Sand: Coarse sand improves drainage and prevents soil compaction.
- Dolomite or Limestone: These materials help raise the soil pH to the slightly alkaline range preferred by Lithops.
Soil Preparation
Before planting Lithops, prepare the soil by mixing the ingredients thoroughly. Use a 50:50 ratio of mineral grit to organic material as a base, and adjust the pH if necessary.

Repot and Fertilize
Whether you’re a seasoned succulent enthusiast or just starting your Lithops journey, knowing when and how to repot and fertilize these fascinating “living stones” is crucial for their health and longevity.
Key Takeaways:
- Repot every 2-3 years, during the growing season.
- Use fast-draining soil specific to succulent requirements.
- Fertilize monthly during the growing season with a balanced, diluted fertilizer.
- Avoid overwatering, especially during the summer dormant season.
Repotting
- Choose a pot with drainage holes and slightly larger than the current one.
- Use a well-draining succulent potting mix or prepare your own by adding perlite or pumice to regular potting soil.
- Carefully remove the Lithops from its old pot, gently shaking off excess soil.
- Place the Lithops in the new pot and fill the space around it with the potting mix, pressing gently to secure it.
Fertilizing
- During the growing season (spring and fall), fertilize your Lithops monthly with a balanced liquid fertilizer, diluted to half strength.
- Avoid using fertilizers high in nitrogen, which can lead to excessive growth and weaken the plant’s defenses.
- Suspend fertilization during the summer dormant season.
By following these simple steps, you can ensure your Lithops receive the nutrients and space they need to thrive. Remember, these unique succulents appreciate a well-draining environment and prefer to be on the drier side, so err on the side of caution when watering and fertilizing.
