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.
Look for blight issues, such as early blight, caused by the fungal pathogen Alternaria solani, which causes black spots in the form of a bull's eye on lower leaves. Examine the ground for yellowed leaves that have dropped early. Search fruit for dark, sunken areas of plant tissue.
