Overwatered Lithops: Causes, Symptoms and Treatment

Oleh Sara Osinski May 22, 2023 Post a Comment

Lithops are fascinating plants that belong to the Aizoaceae family. They are also known as "living stones" due to their resemblance to pebbles or rocks. The most remarkable feature of these plants is their ability to store water in their leaves, which allows them to survive in arid environments. However, overwatering can be fatal for Lithops, causing root rot and eventually killing the plant. In this article, we will discuss the causes, symptoms, and treatment of overwatered Lithops.

Causes of Overwatering

Overwatering is one of the most common mistakes that Lithops owners make. It happens when the plant receives too much water, either by watering it too frequently or by not allowing the soil to dry out between watering sessions. Some of the main causes of overwatering are:

Poor drainage: Lithops require well-draining soil to prevent water from accumulating around the roots.
Watering too often: Lithops should be watered sparingly, especially during their dormant period (winter).
Using the wrong type of soil: Lithops need a gritty, sandy soil mix that allows excess water to drain quickly.

Symptoms of Overwatering

The symptoms of overwatering Lithops can vary depending on the severity of the condition. Here are some of the most common signs to look out for:

Yellowing leaves: Overwatered Lithops may develop yellow leaves, which is a sign that the plant is receiving too much water.
Soft, mushy leaves: If the leaves feel soft and mushy to the touch, it indicates that the plant is suffering from root rot.
Fungal growth: Overwatered Lithops are prone to fungal infections, which can manifest as white or black spots on the leaves.
Wilting: The plant may to wilt and appear droopy if it is overwatered for an extended period.

Treatment of Overwatering

If you suspect that your Lithops is overwatered, there are several steps you can take to save the plant. Here are some tips:

Stop watering: The first thing you should do is stop watering the plant immediately. Lithops can survive for weeks without water, so don't be tempted to give it a drink.
Check the roots: Carefully remove the plant from its pot and check the roots for signs of rot. If the roots are black and mushy, you will need to remove them with a clean, sharp knife.
Let the soil dry out: Allow the soil to dry out completely before repotting the plant in fresh, well-draining soil.
Reduce watering frequency: After repotting, reduce the watering frequency to once every two weeks during the growing season (spring and summer) and once a month during the dormant period (winter).

Other Tips for Caring for Your Lithops

To prevent overwatering and ensure that your Lithops stays healthy, here are some additional tips:

Use a well-draining soil mix: Lithops require a gritty, sandy soil mix that allows excess water to drain quickly.
Water sparingly: Lithops should only be watered when the soil is completely dry. During their dormant period (winter), they should not receive any water at all.
Provide adequate sunlight: Lithops thrive in bright, indirect sunlight. Place them near a window that receives plenty of natural light.
Avoid fertilizing: Lithops do not need fertilizer and can actually be harmed by it.

Overwatering is a common mistake that Lithops owners make, but it can be fatal for these fascinating plants. By understanding the causes, symptoms, and treatment of overwatered Lithops, you can take steps to ensure that your plant stays healthy and thrives.
