Fuchsia: Black root rot
Black 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.

- Dispose of affected plants and related material quickly.
- Prevent contact of contaminated tools or hands with planting media.
- Keep propagation and growing areas clean.
