Why are the leaves always getting black spots on them? What am I doing or not not doing to cause this? They are getting early morning/day sun and afternoon shade. I water regularly and miracle solution once a month or so sometimes more. In the colder months, have gone months without it. I have 4-5 potted plants that have been in the family for over 40 yrs and don't want to lose them. (yellow/orange flowers) Help!
