Why are there black spots on some Hydranga leaves?

Planted in mostly sunny area in March in Atlanta, GA. Have been giving extra water due to drought. Some plants have black spots on leaves - others don’t. How come?

Hi,

It sounds like a fungus (I’m assuming you mean Hydrangia).

Do not do overhead watering. Contact the local garden center and see if you can find some Schultz products. They have a product called Fungicide 3 that is made with neem oil and approved for organic use.
