If you’re a succulent owner and you’ve ever owned a succulent plant, you may have noticed that sometimes the leaves on succulents can turn black. This can be quite concerning, as it can indicate that something is wrong with your plant.
In this article, we will discuss the reasons why your succulent leaves may be turning black and provide some easy fixes to prevent further damage.
Why are succulent leaves turning black?
Here are the reasons why your succulents have turned black:
One common reason why succulent leaves turn black is due to overwatering. Succulents are desert plants and they are adapted to survive in dry conditions.
When they get too much water, their roots become waterlogged and cannot absorb the excess moisture. This leads to root rot, which can cause the leaves to turn black.
On the other hand, underwatering can also cause the leaves to turn black. Succulents store water in their leaves and stems, and if they don’t receive enough water, they can become dehydrated.
This can cause the leaves to dry out and turn black. So, check for underwatering by checking the soil and leaves. Feel the dryness in soil, you will easily understand if it is underwatered.
Succulents love sunlight, but too much direct sunlight can also cause their leaves to turn black.
When succulents are exposed to intense sunlight for long periods of time, their leaves can get burnt and turn brown or black.
Black spots on succulent leaves can be a sign of a fungal infection.
Fungi thrive in moist environments, so if your succulent is constantly wet, it becomes more susceptible to fungal growth.
Pests like mealybugs can also cause black spots on the leaves of succulents. These pests feed on the plant’s sap, causing damage to the leaves and stems.
If your succulent is suffering from root rot, it can cause black spots on the leaves. This happens when the roots are constantly submerged in water and unable to get enough oxygen.
How to Fix Succulent Leaves Turning Black?
Here are the easy to fix ways:
The key to preventing succulent leaves from turning black is to water them properly. Succulents prefer to be watered infrequently but thoroughly.
You can water the succulents once every two weeks checking its soil. If the soil is wet you may skip that day.
Allow the soil to dry out completely between watering sessions and then water the plant until water drains out of the drainage holes.
To avoid overwatering your succulent, make sure to check the soil moisture before watering.
Stick your finger about an inch into the soil and if it feels dry, it’s time to water your succulent. If it still feels moist, wait a few more days.
Ensuring good drainage
Good drainage is essential for succulents to thrive. Make sure that the pot you are using has drainage holes at the bottom. This will allow excess water to escape and prevent the roots from becoming waterlogged.
Removing the Black Succulent Leaves

Check for signs of overwatering
If you notice that your succulent leaves are turning black, check the soil moisture and the condition of the roots.

Check the leaves and stems of your succulent for any signs of pests, such as mealybugs.
If you find any, take appropriate measures to eradicate the pests, such as using potassium soap or insecticide and wiping the plant with rubbing alcohol on the specific leaves that are affected.

If your succulent is suffering from root rot, it is important to repot it in fresh, well-draining soil. Carefully remove the plant from its old pot, trim away any black or mushy roots, and replant it in a new pot with fresh soil.

Potential lack of sunlight

Lack of sunlight can cause the leaves to turn black.
Overwatering due to less evaporation
Indoor environments tend to have less moisture and evaporation compared to outdoor conditions. This can lead to overwatering of succulents, as the excess water takes longer to evaporate.
