If you’re noticing yellow leaves, spots, or some suspicious-looking fuzz, you’re probably eager to figure out what the heck is causing it, so let’s not dally.
1. Alternaria Leaf Spot
If you examine the lower surface of the leaves and notice raised quarter- to half-inch water-soaked spots, it’s time to suspect Alternaria leaf spot.

Bacterial blight is bad news. It causes small sunken spots on the underside of the leaves, and the leaves may eventually wilt while the stem stays firm.

Water molds in the Pythium genus cause a disease commonly known as blackleg. It impacts a wide range of plants, including our lovely geraniums. You usually see it in propagated cuttings but it can happen at any point, and it can spell disaster pretty quickly.
4. Botrytis Blight
Botrytis blight, caused by the fungus Botrytis cinerea, impacts the flowers first – which is both good and bad news.
5. Fasciation
Fasciation (am I the only one whose brain wants to convert that word to “fascination?”) is caused by a bacterial pathogen known as Rhodococcus fascians.
