Hibiscus is a beautiful and popular plant that produces vibrant, showy flowers. However, when the leaves of a hibiscus plant start to turn yellow, it can be a cause for concern. Yellowing leaves can indicate that there is a problem with the plant, and if left unaddressed, it can result in further damage and even death of the plant.
The good news is that there are several potential causes of yellowing hibiscus leaves, and with a little investigation and treatment, the plant can often be restored to health.
Hibiscus Leaves Turning Yellow Causes
- Nutrient deficiency: Hibiscus plants require a balanced diet of nutrients, including nitrogen, phosphorous, and potassium, as well as trace minerals like iron and zinc. If your plant is not getting enough of these nutrients, its leaves may turn yellow.
- Overwatering or underwatering: Both overwatering and underwatering can cause yellowing leaves on a hibiscus plant. Overwatering can lead to root rot, which can cause the leaves to turn yellow and fall off. On the other hand, underwatering can cause the leaves to turn yellow and become crispy due to a lack of moisture.
- Environmental stress: Hibiscus plants are sensitive to extreme temperatures and direct sunlight. If the plant is exposed to too much heat or direct sunlight, the leaves may turn yellow and wilt.
- Pest infestation: Yellowing leaves can also be a sign of a pest infestation, such as aphids or mites. These pests can suck the sap from the leaves, causing them to turn yellow and eventually die.
- Disease: Hibiscus plants can be prone to various diseases, including fungal infections and bacterial infections. These diseases can cause the leaves to turn yellow and eventually fall off.
- Poor soil quality: Hibiscus plants need well-draining soil that is rich in organic matter. If the soil is too heavy or has a poor drainage, it can cause the roots to suffocate and the leaves to turn yellow.
- Pruning: Over-pruning or improper pruning techniques can also cause yellowing leaves on a hibiscus plant. It’s important to only remove dead or damaged branches and to prune the plant correctly to avoid stressing it.
- Age: As hibiscus plants grow older, they may naturally produce fewer leaves and the remaining leaves may turn yellow and fall off. This is a normal part of the plant’s life cycle and is not necessarily a cause for concern.
Hibiscus Leaves Turning Yellow Treatment
Yellowing leaves on a hibiscus plant can be a sign of an underlying problem that needs to be addressed in order to keep the plant healthy and thriving. Fortunately, there are several potential treatments that can help to address the cause of the yellowing leaves and restore the plant’s health.

Hibiscus Leaves Turning Yellow After Transplant
If your hibiscus leaves are turning yellow after transplant, it could be a sign of transplant shock. Transplant shock is a common problem that occurs when a plant is moved from one location to another.
During this process, the plant may experience stress, which can cause leaves to turn yellow or brown and fall off. To help your hibiscus plant recover from transplant shock, it’s important to make sure it is getting enough water and nutrients.
Water the plant regularly and ensure that it is planted in nutrient-rich soil. Additionally, you can try adding a transplant solution that contains nutrients and beneficial microorganisms to the soil. This can help to encourage healthy root growth and reduce the stress on the plant.
With proper care and attention, your hibiscus plant should recover from transplant shock and start producing healthy, vibrant leaves once again.
Hibiscus Leaves Turning Yellow With Brown Spots
If your hibiscus leaves are turning yellow with brown spots, it could be a sign of a fungal or bacterial disease. One common disease that causes these symptoms is leaf spot, which is caused by a fungus.
Leaf spot starts as small brown spots on the leaves that gradually grow larger and turn yellow. If left untreated, the leaves may fall off. To treat leaf spot, it’s important to remove affected leaves and prune back any heavily affected areas of the plant.
Additionally, treating the plant with a fungicide can help to eliminate the fungus and prevent further damage to the plant.
Why Are My Hibiscus Leaves Turning Yellow With Black Spots?
If your hibiscus leaves are turning yellow with black spots, it could be a sign of a fungal or bacterial disease. One common disease that causes these symptoms is anthracnose, which is caused by a fungus.
Anthracnose typically appears as black or brown spots on the leaves, which gradually grow larger and turn yellow. If left untreated, the leaves may fall off. To treat anthracnose, it’s important to remove affected leaves and prune back any heavily affected areas of the plant.
Additionally, treating the plant with a fungicide can help to eliminate the fungus and prevent further damage to the plant. Another potential cause of yellow leaves with black spots is bacterial leaf spot, which is caused by a bacterium.
To treat bacterial leaf spot, it’s important to remove affected leaves and prune back heavily affected areas of the plant. Additionally, treating the plant with an appropriate bactericide can help to eliminate the bacteria and prevent further damage to the plant. By addressing the underlying cause of the problem, you can help to keep your hibiscus plant healthy and vibrant.
Potted Hibiscus Leaves Turning Yellow
If your potted hibiscus leaves are turning yellow, it could be a sign of over or under watering. Overwatering can cause the roots to become waterlogged, leading to root rot and a lack of oxygen, which can cause the leaves to turn yellow.
Under watering can cause the plant to become dehydrated and the leaves to turn yellow as well. To remedy this, make sure the plant is potted in well-draining soil and that the pot has adequate drainage holes.
Check the soil regularly and only water when the top inch of soil feels dry to the touch. When watering, water deeply until water runs out of the drainage holes. It’s also important to provide the plant with appropriate sunlight, as too little or too much can also cause yellowing.
With proper care and attention, your potted hibiscus should recover and produce healthy, vibrant leaves once again.
Hibiscus Leaves Turning Yellow Overnight
If your hibiscus leaves are turning yellow overnight, it could be a sign of sudden environmental stress. This can be caused by a variety of factors, including extreme temperatures, pest infestations, or sudden changes in light or water conditions.
One potential cause of yellowing overnight is cold temperatures, which can cause stress and damage to the plant. Another potential cause is an infestation of spider mites, which can cause the leaves to turn yellow and fall off rapidly.
To address sudden yellowing, it’s important to identify and address the underlying cause of the problem. This may involve treating the plant for pests, adjusting watering and lighting conditions, or taking steps to protect the plant from extreme temperatures.
By addressing the problem promptly, you can help to prevent further damage and ensure the health and vitality of your hibiscus plant.
