Lithops Monthly Watering Calendar — Month-by-Month Guide

Lithops have a unique watering cycle that confuses many growers. Follow this month-by-month watering calendar to keep your living stones alive and thriving year-round. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: Lithops have an annual growth cycle of splitting, growing, flowering, and dormancy that dictates watering. The old leaf pair is absorbed to feed the new pair — watering during this split phase rots the plant. Most lithops flower in autumn (October-November) and split in late winter through spring (February-April). In the Northern Hemisphere, lithops are typically fully dormant and need zero water from December through March. Each species varies slightly but the general calendar works for the most commonly grown lithops varieties. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: Watering during the splitting phase (Feb-April) is the number one killer of lithops collections. Using a standard succulent watering schedule leads to overwatering since lithops need far less water. Humid environments add moisture that the lithops absorb through their skin, requiring even less watering. Heavy soil that retains moisture keeps roots wet far longer than lithops can tolerate. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: January-March: No water at all — the plant is splitting and the old leaves feed the new pair. April-May: Resume light watering only after the old leaf pair is completely shriveled and papery. June-August: Water deeply once every 2-3 weeks when soil is bone dry — this is the active growing season. September-November: Water lightly to trigger flowering, then reduce as temperatures cool. December: Stop watering completely as the plant enters its winter dormancy and prepares to split. If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
