The Q&A Archives: Black Eye Susan

Question: Hi. Started garden 9 years ago. One side of the Black Eye Susan garden is hardy, getting bigger each yr. Other side, I have had to add plants each yr to keep up with other side (always buying from same nursery, replenishing soil & compost). This yr, some of the leaves have brown spots. Is this a fungus? How do I treat it? I prefer organic solution. How do I protect other plants in same area?
