Zinnias are colorful, low-maintenance annuals that prefer warm weather and bright sunlight. Although zinnias are relatively disease-resistant, they are sometimes plagued by diseases that cause brown spots. The brown spots are usually caused by one of three types of leaf spot -- Alternaria leaf spot, bacterial leaf spot and Cercospora leaf spot.
Leaf Diseases. Fungal diseases from various pathogens cause leaf spots, blotches and blisters on birch trees. Cylindrosporium and Septoria cause small spots with no borders and Colletotrichum causes larger brown spots with darker borders.
