What Causes Brown Spots on Plants?

Answer

The main causes of brown spots on plants are fungi, insects, bacteria, and various environmental elements. Fungi can be found commonly at the top or the stem of the leaves causing large blotches of brown spots on the plant. Insects such as mites, aphids, whiteflies, scales, thrips, and nematodes eat the plants and decay their structures. Bacteria can grow on plants and make them sickly and withered. Finally, environmental aspects such as pH, overuse of fertilizers, poor nutrition, sunlight exposure, and use of cold water can make the leaves of a plant look dull.
