| Coleus? Is that what you are talking about? There are many different kinds of fungi that grow on the mulch that we use in our landscaping beds. Without a better description, we cannot help you identify what this might be. However, I will tell you that fungi growing on the mulch is one hundred percent not harmful to your camellia. (I sure would get rid of that coleus!) I would not spray with Lysol or anything else. Unless you can do a better job at describing this stuff, we can only assume that you have what jillions of others have complained about: a decomposing fungus of some kind, or a slime mold....both of which are totally harmless to your camellias. |
