Lithops (Living Stones)
Lithops, also known as Living Stones, are fascinating succulents that mimic the appearance of pebbles or stones. These unique green plants have evolved to blend into their native desert environment and make intriguing additions to succulent collections.
Lithops (Living Stones) Care Guide
Environment
Lithops prefer bright locations with some direct sun. They require very specific watering cycles based on their growth pattern and dormancy periods.
Light
Bright light with some direct sun is essential. South-facing windows are ideal. Insufficient light causes elongated growth and poor coloration.
Temperature
Prefers temperatures between 65-80°F (18-27°C) during growing season. Can tolerate cooler temperatures during winter dormancy.
Watering
Follow a specific watering schedule based on their annual cycle: Water sparingly in spring and fall, almost none in summer, and very little in winter. Never water when splitting or during dormancy periods.
Humidity
Tolerates dry air very well. No need for additional humidity measures.
Fertilizing
Minimal fertilizer needed. Apply a very diluted succulent fertilizer once in spring and once in fall. Avoid fertilizing during summer dormancy and winter splitting.
Care Tips
- Use extremely well-draining soil mix with at least 80% mineral content (pumice, perlite, coarse sand).
- Choose a deeper pot than seems necessary as Lithops have long taproots.
- Learn to recognize their annual cycle: new leaves emerge by splitting the old ones in winter/spring.
- Never water when the plant is splitting or has just completed splitting.
Common Problems
- Soft, mushy appearance indicates overwatering - the most common cause of death.
- Wrinkling during summer dormancy is normal and not a sign to water.
- Elongated growth indicates insufficient light.
- Failure to split and produce new leaves may indicate improper dormancy periods or watering schedule.
Seasonal Care
Spring
Old leaves wither as they transfer nutrients to new leaves. Water lightly once old leaves are completely dry.
Summer
Dormant period - water very sparingly or not at all.
Fall
Growth resumes - water lightly when soil is completely dry. May flower in late fall.
Winter
New leaves begin to emerge by splitting the old ones. Do not water during splitting.
