| the leaves are turning blotchy then yellow then falling off my impatiens. what can I use to treat them. I need a brand of chemical and where can I buy it. |
| It sounds as though your impatiens have developed a fungal disease. This can happen when conditions are too wet or when plants are overcrowded. Disease pathogens need three things to become established: a susceptible host (usually a plant that's under stress), a pathogen, and the right environmental conditions. Your best defense against disease problems is to provide all of the cultural requirements necessary for healthy growth, keep water off leaves as much as possible, and remove diseased plant parts as soon as you notice them. If leaves on the entire plant are affected, it may be too late to save your impatiens. If only a few leaves and stems have symptoms, cut them off the plants to encourage healthy new growth. Funginex is the chemical of choice for controlling fungus diseases on impatiens. |
