Bacterial infections are often sneakier and harder to notice. They are spread by a number of different possible vehicles, ranging from insects and humans to rain and unclean soil or substrate. Bacteria can sometimes get into a plant and then leave it mostly untouched unless the plant is weakened by external stresses, at which point they can quickly take down the whole plant.
Proper treatment of a fungal or bacterial disease requires a knowledge of the potential symptoms, which we’ll list below. As always, the best defense against disease is prevention. Do your best to create an environment which is healthy for plants and inhospitable for fungus and bacterial growth.
