Plant NameTypeDescription 
Black root rotFuchsiaDiseaseBlack root rot is caused by a widely distributed fungal root pathogen. Untreated or mismanaged field soil can be the source of the fungus. Spores can be found in commercial peat moss. The pathogen forms thick-walled chlamydospores, which can survive for several years in the soil. Materials exuded by roots stimulate germination of chlamydospores. Root rot tends to worsen in neutral or alkaline soils, and is generally of greater concern in soil temperatures between 55 and 70 degrees F, and soil that holds a lot of moisture. Fuchsias may appear chlorotic or stunted. Roots initially appear brown, and eventually develop flat, black lesions.
RustFuchsiaDiseaseFuchsia rust is caused by a fungus. It also affects fireweed and true firs. It produces yellowish spores on fir needles. Spores produced on firs then infect fuchsia. Older leaves are more susceptible, and low light encourage the disease. The rust can overwinter on fuchsia and maintain itself indefinitely, independent of alternating to fir. Pale, yellowish spots appear and may change rapidly to tan or brown necrotic spots. On some cultivars, spots may bear purple borders and appear on only a few leaves. Tiny yellow to reddish fruiting bodies (uredinia) develop in jumbled groups along borders of spots on leaf undersides, which are easily overlooked. Heavily affected leaves dry up and drop; in extreme cases, whole plants may die.
Fuchsia gall miteFuchsiaInsectThe fuchsia gall mite is a tiny eriophyid mite which infests shoot tips, young leaves, and flower buds. Damage appears as distortion, twisting, blistering, or swelling. Tissues may become thickened and form irregular, light green to reddish galls. The pale yellow adult mites are extremely small (less than 1/100 inch long). Because of their size, they are unlikely to be noticed on the plant, so galling is usually the first sign of an infestation. Adults are wormlike in shape, with two pairs of legs at the front of the body. The mites hide within plant structures, such as galls, bud scales, or loose bark. They typically spread by wind currents and may also be moved between plants by physical contact, including humans, insects, and hummingbirds. Fuchsia gall mites are a pest primarily in cool, coastal regions with mild winters.
