Hi, I read the earlier post about another person's leaves turnign red. I understand that certain species will turn red come Fall, however, mine seem unhealthy in addition to the coloration.
These 3 plants were purchased from 2 different nurseries earlier this summer and all 3 are planted in a row, with decent drainage and mostly sun. The broad leaves are almost completely maroon in color, the flowers seemed to last for a very short period of time before they withered, and the interior of the plant appears stalky, woody and unhealthy. Some of the leaves have brown crunchy sides or areas as well. The plants were sprayed with a fungicide at the end of June after we had nearly a whole month of rain.
Any thoughts? Should I hit them with a fungicide again?
