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.
It is believed that the same accumulated sun damage that causes brown spots also causes white spots. Brown spots occur when the cells in your skin that produce color (melanin) have been bombarded by sun damage to the point where they start reproducing and growing abnormally, causing spotty, dark discolorations.
