The Apothecary
Every trouble the companion knows how to name — the fungi, the molds and bacteria, the viruses, and the disorders that are nobody's fault but the weather's. Search by what you can see on the plant, or leaf through by kind; each entry opens with its symptoms, the real cause, how to treat it, and how to keep it from coming back.
