Devil’s Trumpet, also known as Brugmansia, is a popular and beautiful plant that can add a touch of elegance to any garden or patio. However, it can be frustrating when your plant begins to wither and die for seemingly no reason. In this article, we’ll explore some of the common causes of Devil’s Trumpet plants dying and what you can do to prevent it.


One of the most common causes of Devil’s Trumpet plants dying is overwatering. These plants prefer moist soil but not waterlogged conditions. Overwatering can cause root rot, which will eventually kill the plant. Signs of overwatering include yellowing leaves, wilted or mushy stems, and a foul smell emanating from the soil.

To avoid overwatering your Devil’s Trumpet, ensure that the soil is well-drained and only water when the top inch of soil feels dry to the touch. Additionally, make sure that your pot has drainage holes to allow excess water to escape.


On the other hand, underwatering your Devil’s Trumpet can also cause it to die. These plants require regular watering to thrive, especially during hot weather. Signs of underwatering include dry and brittle leaves, brown edges on leaves, and wilting.

To avoid underwatering your Devil’s Trumpet, make sure that you water it regularly, especially during hot weather. However, ensure that you don’t overwater it as well by monitoring the moisture levels in the soil.


Pests such as spider mites, aphids, and whiteflies can also cause Devil’s Trumpet plants to die. These pests feed on the sap from the leaves and stems of the plant, causing them to wilt and eventually die.

To prevent pest infestations, regularly inspect your plant for signs of pests such as webbing, sticky residue, or distorted leaves. You can also use insecticidal soap or neem oil to control the pest population.

Fungal Diseases

Fungal diseases such as powdery mildew and leaf spot can also cause Devil’s Trumpet plants to die. These diseases are caused by excess moisture on the leaves and stem of the plant.

To prevent fungal diseases, ensure that the plant is not overcrowded and that there is enough airflow around it. Additionally, avoid watering the leaves and stems of the plant and instead focus on watering the soil.
