Complete Lithops Care Guide — Mastering Molting & Dormancy

Lithops are succulent plants native to South Africa, also known as "living stones" or "mesembs." Their unique stone-mimicking appearance and the distinctive window patterns that vary by species are their main attractions. However, their watering cycle differs drastically from typical succulents, and growing them without proper knowledge often leads to failure. Here we explain the annual care cycle for lithops and how to avoid common mistakes.

Understanding the Annual Growth Cycle of Lithops

Successfully growing lithops starts with understanding their unique growth cycle.

Fall to Winter (October-February): Growing Season This is the most active period for lithops. They flower in fall and form new leaves internally through winter. Moderate watering and sunlight are needed during this time.

Spring (March-May): Shedding Season The most distinctive feature of lithops occurs—shedding (molting). New leaves push out from between the old leaves, which gradually shrivel and die. Watering management during this period is most critical.

Summer (June-September): Dormancy Japan's hot, humid summers are the harshest season for lithops. Growth nearly stops as the plant enters energy conservation mode. Overwatering during this period is the leading cause of death.

Shedding Season Management Is the Key to Success

Shedding is the most important event in lithops cultivation. Mistakes in management can cause double-shedding (shedding within shedding), weakening the plant.

Stop watering once shedding begins When new leaves become visible through the gap in old leaves, stop watering completely. New leaves absorb moisture from the old leaves to grow, so external water is unnecessary. In fact, watering prevents the old leaves from shriveling, causing double-shedding.

Let old leaves run their course naturally Never forcibly peel off old leaves. Unless mold develops, leave them alone until they've completely shriveled to a paper-like state. Once old leaves are completely dry, gently remove them.

Signs shedding is complete Shedding is complete when old leaves have dried to thin husks and new leaves have fully expanded. Resume watering at this point. This typically occurs around late April to May, though it varies by variety and conditions.

Proper Watering Timing and Methods

Watering lithops is fundamentally different from other succulents.

Watering during the growing season (fall-winter) Water 5 to 7 days after the soil has completely dried. Roughly 2 to 3 times per month is a guideline, but adjust based on weather and temperature. Water thoroughly until it flows from the drainage holes, and always discard water from saucers.

Watering during dormancy (summer) The general rule is no watering. However, if the plant becomes visibly wrinkled, give a very small amount of water on a cool evening. Just enough to moisten the soil surface is sufficient. Watering during daytime heat causes steaming and rot.

Watering don'ts Avoid showering water from above. Water collecting in the leaf gap causes rot. Gently pour water at the base of the plant, or use bottom watering.

Placement and Light Management

Lithops love light, but Japan's summers require caution.

Direct sunlight is generally fine During the growing season, give them plenty of direct sunlight. Insufficient light causes etiolation (stretching), distorting the shape and reducing flowering. Even in winter, provide direct sunlight through glass on sunny days.

Summer shading is essential Use about 50% shade cloth from June through September. The sudden intense light after the rainy season poses a high risk of sunburn, so prepare shading measures early. Place in a well-ventilated location, and on days exceeding 35 degrees Celsius, bringing them indoors is one option.

Never leave them exposed to rain For outdoor management, locations where rain falls directly are absolutely off-limits. Keep them under cover or under eaves where rain can't reach. Extended rainy season downpours are particularly lethal.

Choosing Lithops Varieties and Acquisition Tips

Lithops come in over 100 varieties, each with unique window patterns.

Beginner-friendly varieties L. aucampiae (Nichirin-gyoku), L. karasmontana (Kamon-gyoku), and L. bella (Kohaku-gyoku) are relatively hardy and easy to grow. We recommend starting with these varieties to become familiar with the annual cycle.

Collector varieties The L. lesliei (Shikun) group offers rich color variations and high collectibility. L. dorotheae (Reikoh-gyoku) features delicate patterns and is popular among advanced growers.

What to check when buying Since lithops often look different in person compared to photos, buying from trustworthy sellers is important. On BriChoku, specialist breeders sell directly, ensuring accuracy in variety names and plant health. Being able to ask care questions easily makes BriChoku reassuring for first-time lithops owners too.
