My blackeyed susans have black spots or dark spots
on the leaves. Is there a certain product I should use to get rid of
the darkening of the leaves?
Thank you

Leaf spots are caused by fungi or bacteria and are actually quite common on Black Eyed Susan plants. Splashing rain, insects, dirty garden tools, or even people can help its spread. The best approach is to remove the infected leaves when the plant is dry. Leaves that collect around the base of the plant should be raked up and disposed of. Avoid overhead irrigation if possible; water should be directed at soil level. For fungal leaf spots, use a garden fungicide according to label directions. Safer's Garden Fungicide is one brand name and you will find others in your garden center. Best wishes with your garden.
