Dragon Fruit Turning Yellow

Yellowing of the dragon fruit is a concern for growers as it can indicate a problem with the plant’s health or the growing conditions. Yellowing can affect the fruit’s appearance and quality, and if left untreated, can lead to reduced yields and even plant death. Know the causes of yellowing in dragon fruit, prevention and treatment methods, and the importance of timely intervention to ensure a healthy crop.

Causes of Yellowing

Overwatering: Dragon fruit plants are sensitive to waterlogged soil, which can lead to yellowing of the fruit. Overwatering can cause the roots to rot and inhibit the plant’s ability to absorb nutrients, leading to yellowing.

Nutrient deficiencies: A lack of essential nutrients such as nitrogen, potassium, and magnesium can cause yellowing of the leaves and fruit. A soil test can help determine if the plant is deficient in any specific nutrients.

Pests and diseases: Pests such as scale insects and mealybugs can suck the sap from the plant, causing yellowing and weakening the plant. Diseases such as powdery mildew and anthracnose can also cause yellowing and fruit rot.

Environmental factors: Extreme temperatures, high winds, and intense sunlight can all cause stress on the plant and lead to yellowing. Additionally, a sudden change in temperature or light conditions can also cause yellowing in the fruit.

It’s important to note that yellowing can be caused by a combination of factors or a single one. Therefore, it’s important to inspect the plants regularly and to consider the environmental conditions and the symptoms of the plant to identify the cause of yellowing.

Prevention and Treatment

Proper watering and fertilization: To prevent yellowing caused by overwatering, it’s important to let the soil dry out slightly between watering and to make sure that the drainage is adequate. Fertilizing with a balanced fertilizer according to the soil test results, can help to prevent nutrient deficiencies and yellowing.

Pest and disease control: Regular inspections of the plants can help to identify and address any issues with pests or diseases. Pesticides and fungicides can be used to control pests and diseases, but it’s important to follow the instructions and safety precautions carefully.

Maintaining appropriate temperature and humidity: Dragon fruit plants prefer warm temperatures and high humidity, so it’s important to provide the appropriate conditions for the plant to thrive. If the plant is exposed to extreme temperatures or sudden changes in light conditions, yellowing can occur.

Regular inspections and prompt removal of affected fruits: Regularly inspecting the plants and removing any yellowing or diseased fruit can help to prevent the spread of problems and ensure a healthy crop.

Consultation with experts: If you are facing recurrent yellowing problem and are not able to identify the cause and solution, it’s advisable to consult with experts in horticulture, agriculture or local extension services to get the best advice.

Prevention and treatment of yellowing in dragon fruit requires careful observation of the plant’s health and growing conditions, as well as prompt intervention when issues are identified. By following these recommendations, you can help to prevent yellowing and ensure a healthy crop.


Yellowing of dragon fruit can be caused by a variety of factors including overwatering, nutrient deficiencies, pests and diseases, and environmental factors. To prevent yellowing and ensure a healthy crop, it’s important to practice proper watering and fertilization, control pests and diseases, maintain appropriate temperature and humidity, and conduct regular inspections and prompt removal of affected fruits.
