Caladiums are popular ornamental plants known for their vibrant foliage. However, they can be susceptible to various diseases that affect their health and appearance. Proper identification and treatment are essential for maintaining a healthy plant. This article provides guidance on how to recognize common diseases in divided caladiums and effective methods for treatment.
Common Diseases Affecting Divided Caladiums
Fungal Diseases
Fungal infections are among the most common problems in caladiums. They typically thrive in moist, poorly drained soil or during periods of high humidity. Recognizable signs include leaf spots, mold, and rotting bulbs.
Bacterial Diseases
Bacterial infections can cause soft, mushy spots on leaves and stems, often accompanied by a foul smell. These diseases spread quickly in warm, wet conditions and can lead to plant death if untreated.
