The disease symptoms of this fungal disease on pachysandra include brown or black spots on leaves that may enlarge and blight the entire leaf or stem. Infected plants may turn black and become soft. In wet weather pink spores will be visible on infected surfaces. Under drier conditions the brown spots may have a target appearance or have concentric rings.

Management

Avoid overhead irrigation and thin plantings to increase air circulation that will promote faster leaf drying. Thinning can be accomplished by selective pruning of infected leaves or by mechanical removal such as with a lawn mower set at the highest setting. Removal of fallen debris and clean up of old leaves etc. will also help reduce the amount of moisture trapped and will promote faster drying of the planting bed.
