- Pest infestations, such as mealybugs or aphids, can damage succulents and cause yellowing leaves. Treating infestations promptly is essential.
Overwatering and Underwatering
One of the most common reasons for succulent leaves turning yellow is overwatering. Succulents are adapted to dry conditions and storing water in their leaves, so watering them too frequently can lead to the roots becoming saturated and unable to absorb water properly. To prevent your succulent from turning yellow due to overwatering, make sure to water it only when the soil is dry. Check the moisture level by sticking your finger about an inch into the soil. If it feels dry, it’s time to water.
On the other hand, underwatering can also cause yellowing and dried-out leaves. Succulents still need water to survive, so neglecting to water them can lead to dehydration and discoloration. It’s important to find the right balance and provide your succulent with enough water without overdoing it. Remember that different succulent species have different water needs, so it’s always best to research the specific requirements of your plant.
How to prevent succulent from turning yellow due to overwatering:
- Ensure the soil has good drainage to prevent water from sitting in the pot.
- Use a well-draining potting mix specifically designed for succulents.
- Water your succulent thoroughly but allow the soil to dry out completely before watering again.
- Consider using a moisture meter to accurately gauge the moisture level of the soil.
How to save a yellow succulent due to underwatering:
- Gradually increase the frequency of watering, allowing the soil to fully absorb the water.
- Ensure that the soil is thoroughly saturated during watering sessions.
- Monitor the plant closely and adjust the watering schedule as needed to prevent underwatering or overwatering.
By understanding the importance of proper watering and finding the right balance between overwatering and underwatering, you can help prevent your succulent from turning yellow and keep it healthy and vibrant.
Lack of Sunlight and Too Much Sunlight
Lack of sunlight or too much sunlight can both contribute to yellowing succulent leaves. It’s important to find the right balance and provide your succulents with adequate sunlight to keep them healthy and vibrant.
Effects of Lack of Sunlight
When succulents don’t receive enough sunlight, their leaves may become pale or turn yellow. This is a sign that the plants are stretching and reaching for more light. Lack of sunlight can also slow down their growth and make them more susceptible to disease and pest infestations.
Effects of Too Much Sunlight
On the other hand, too much sunlight can cause sunburn and lead to brown or yellow leaves. Succulents that are exposed to intense, direct sunlight for prolonged periods can become stressed and show signs of sunburn. It’s important to provide indirect sunlight for at least 6 hours a day to prevent sunburn and keep your succulents healthy.

Solutions and Prevention
To address the issue of lack of sunlight, you can try the following:
- Move your succulents to a brighter location, such as a south-facing window or a well-lit area in your home.
- Consider using grow lights to supplement natural sunlight, especially if you have limited access to sunlight.
- Rotate your succulents regularly to ensure all sides receive equal sunlight exposure.
To prevent the negative effects of too much sunlight, you can:
- Provide shade for your succulents during the hottest part of the day, such as using sheer curtains or placing them under a patio umbrella.
- Adjust the position of your succulents to avoid intense, direct sunlight, especially during the peak hours of midday sun.
- Use window coverings like curtains or blinds to filter the light and protect your succulents from excessive sun exposure.
By maintaining the right balance of sunlight, you can help prevent yellowing of succulent leaves and promote their overall health and well-being.
Root Rot
One of the common causes of yellowing succulent leaves is root rot. This fungal disease occurs when succulents are overwatered or planted in poorly draining soil. It starts below the soil surface and can cause the leaves to turn yellow or black.
If you suspect root rot in your succulent, it’s important to take immediate action. Start by carefully removing the affected plant from the soil and gently shaking off any loose soil from the roots. Trim off any soft, mushy, or blackened roots using clean and sterilized scissors or shears. Be sure to also remove any yellow or blackened leaves.
After removing the affected parts, give the plant’s roots some time to dry out and heal before replanting. During this time, it’s crucial to provide the plant with fresh, well-draining soil. You can use a mix of succulent or cactus soil with added perlite or coarse sand to improve drainage. Avoid overwatering the plant during this period to prevent further damage and allow the roots to recover.
To prevent root rot in the future, it’s important to ensure your succulents are planted in well-draining soil and that you follow proper watering practices. Check the moisture level of the soil before watering and only water when it is completely dry. Avoid letting your succulents sit in standing water, as this can promote the growth of fungi and lead to root rot.
Table: Signs of Root Rot and Treatment
| Signs of Root Rot | Treatment |
|---|---|
| Yellowing or blackening of leaves | Remove affected plant from soil, trim affected roots and leaves, replant in well-draining soil |
| Soggy or mushy roots | Allow roots to dry out and heal before replanting, provide fresh soil with improved drainage |
| Foul odor from the soil | Remove affected plant from soil, trim affected roots and leaves, replant in well-draining soil |
Pest Infestations
One of the common causes of yellowing succulent leaves is pest infestations. Pests such as mealybugs and aphids can damage the plant by feeding on its sap. This can lead to stress and discoloration of the leaves. If you notice pests on your succulents, it is important to take immediate action to prevent further infestations and save your plant.
To address pest infestations, start by isolating the affected plants to prevent the pests from spreading to other healthy plants. You can manually remove the pests by gently wiping them off the leaves with a cotton swab soaked in rubbing alcohol. For more severe infestations, you can use insecticides labeled for use on succulents or natural remedies like neem oil.
When using insecticides, always follow the instructions carefully and avoid applying them during the hottest part of the day or when the plant is under stress. Additionally, consider using organic and environmentally friendly pest control methods to minimize harm to beneficial insects and the environment as a whole.
Table: Common Pests and Treatment Methods
| Pest | Treatment |
|---|---|
| Mealybugs | – Manual removal with rubbing alcohol-soaked cotton swabs – Insecticides labeled for use on succulents – Natural remedies like neem oil |
